The display should show several DOS text style screens. A penguin image will appear in the upper left corner of the screen as the boot sequence progresses.
Check that the software is OK: Is the correct software installed? Did you just install new software? Check the display. If the Q5 board is booting but you have no display, check the following: Check the LCD backlight tube. Look very closely at the display to see if anything. Using a beam type source of good lighting, such as a ashlight, look for any ghost type image. If it appears that there is something on the screen but very dark, the problem may be with the LCD backlight tube.
There is a sticker on the display mounting plate, that will have a part number that describes the type of display. If there is no sticker, you must take the display apart to identify the display manufacturer. Verify that both the display cable and the inverter cable are rmly seated. It may be necessary to remove the video cable from the back of the LCD display and re-seat it to be sure it is connected properly.
Note: This is a small connector and caution should be observed so that it is not damaged due to excessive force. Locate the Battery socket, as shown on the following drawing:. Place your ngernail under the edge of the battery, and gently lift up. The battery should release itself from the socket easily. Take a new battery and place it into the holder in the same orientation as the old battery the side with the writing must be facing out.
Return the Control Power switch back to ON. Once the Q5 has rebooted, the correct Date and Time must be set. A photo of this interface board is shown here:. If the date and time are not being maintained properly, this may indicate that the battery is not functioning, and should be replaced. The battery is fully assessable, but is surrounded by sensitive electronic components, so care should be. NOTE 2: Although the Q5 board is the main controller, most of customer connections will be to the Interface board, as shown later.
Each of the interconnecting harnesses must be installed as shown for proper operation. Over time, it is possible for temperature, humidity, vibration and component age, to degrade the accuracy of these voltages. When any of the DC voltages begin to stray from their optimum range, mysterious problems can begin to arise. Even with a perfectly adjusted supply, it is possible for a potential drop in voltage at each connection point. This drop normally is in the millivolt range, but under some conditions, the drop can be much greater as high as tenths of a volt.
By the time the voltage reaches the last board in the daisy chain, and all of these potential voltage drops are considered, the combined drop can be such that problems can be apparent. Some examples of problems could be: Loss of or intermittent communications failures. A shutdown message stating Digital Board x Reset where x is replaced by the number of the Digital Board that failed.
An shutdown message stating Digital Board x Comm. Fail - Shutdown where x is replaced by the number of the Digital Board that failed.
An shutdown message stating Analog Board x Comm. Fail - Shutdown where x is replaced by the number of the Analog Board that failed. Numerous sensor fault shutdown messages. Q5 reboots for no apparent reason.
Improper readings of analog pressures and temperatures. LED's on the Q5 are lit, but nothing appears on the display. All three supplies are adjustable and each has an indicator to show that they are powered. Refer to the following page for the location for the adjustment. Measuring and adjusting the power supply voltages require the control power switch to be energized. Extreme care must be observed when taking any readings, as or VAC depending on incoming system voltage will be present next to the DC voltage connector.
Adjusting the supplies requires the use of a small Philips screwdriver inserted into the supply to access an adjusting potentiometer. CAUTION: It is possible for the screwdriver and the person making the adjustment to come into contact with potentially lethal voltages. All circuit boards within the Q5 control panel require accurately adjusted DC voltages in order to function properly.
Periodic measurement and adjustment of. To perform measurements and adjustments on the power supply voltages, use a reliable, calibrated Digital Volt Meter DVM. With the control power switch turned ON, wait until the Operating Screen appears. This is because the graphics required to create this screen will draw more current than when the screen is showing the normal POST DOS style messages during a boot up.
If the screen never appears however possibly due to a voltage problem , you will need to proceed regardless of what is or is not displayed. In order to properly measure the DC power system, it must be checked at the DC power terminal strip.
The power supply drawing shown on the following page applies to all three power supplies. The adjustment access hole for each supply is located on the lower left of the front of the supplies.
If an adjustment is required, use a thin, Philips screwdriver, insert the tip into the access hole for the appropriate voltage potentiometer refer to the diagram on the following page for adjustment location. NOTE: Extreme care must be used when adjusting the potentiometer. Adjustment should only be performed by qualied personnel.
The use of a non-conductive device is recommended. Locate the DC power terminal strip. Place the negative lead on , and the positive lead on While watching the DVM, slowly rotate the screwdriver blade clockwise to increase the voltage or counter-clockwise to decrease until the voltage is correctly adjusted. Refer to the Recommended Spare Parts list for the appropriate part number. This pictorial represents a typical conguration using the Q5, and is not to scale.
Specic units may or may not have both Digital and Analog boards, depending on options. Additionally, exact wiring to and from the DC Power Terminals is for reference only.
The pictorial is meant to show the proper interconnection of the D. Refer to the wiring diagrams later in this manual for exact connections. This drawing appears here for reference purposes only, and is subject to change without notice. When installing, or servicing equipment, always refer to the actual drawings that are included with the control panel for the latest information. Because of the ever-increasing speed, memory features, and power of microprocessors, Frick will continue to introduce the latest advancement in microprocessor control technology.
Just before fully booting, a Loading bar will appear at the bottom of the screen, showing the percent of load that has completed. Quantum 4 Board If the powering up sequence continues to repeat without displaying the Operating Status screen, then there is a booting problem. It is normally not lit. LED D8 on the smaller board will start to blink at the rate of about once-per-second.
It will continue to blink after the Quantum 4 has booted. The only time that this ashing rate is interrupted, is when a key is pressed on the keypad. A penguin image will appear 6. Check for bad connections. Be sure to write down any error messages exactly as they appear.
Remove Flashcard and reboot. This will cause the Quantum 4 to boot under a preLX operating software. If it boots properly under this older software, then trying re-booting from the Flashcard again. If it doesnt boot with the card, then the Flashcard could be corrupted, and needs to be replaced. If the Quantum 4 board is booting but you have no display, check the following: Check the LCD backlight tube. Look very closely at the display to see if anything is visible in the dark screen.
On the Samsung LCD display it is not available and the display will have to be replaced. There may be a sticker on the display mounting plate. If there is, it will have a part number that describes the type of display. These cables both originate from the same connector on the Quantum 4. If the date and time are not being maintained properly, it may indicate that the battery is not functioning, and should be replaced.
The battery is partially covered by the communications daughter board, and is located directly beneath the COM1 port it may be necessary to unplug any connector that is plugged into COM1 to fully access the battery. Simply push the clip away from the battery, to release the battery from the holder. Remove the battery, observing the orientation. Once the Quantum 4 has rebooted, the correct Date and Time must be set.
PL7 LK1. LX panels use the Sharp display. Controller Board Pictorial Note: There are duplicate numbers for the links on the processor larger board and the communications smaller board. If you must make a change to a jumper link , ensure that you modify the correct link. Some examples of serious problems could be: Loss of or intermittent communications failures.
Quantum 4 reboots for no apparent reason. LED's on the Quantum 4 are lit, but nothing appears on the display. Refer to the following page for the location of this potentiometer adjustment.
If no reason can be found for the loss of any DC voltages, then the power supply will need to be replaced. Periodic measurement and adjustment of the DC power system is highly recommended for optimum system operation. All four DC voltages originate from the power supply. They are then daisy-chained to the main board, and then on to all connected Digital and Analog boards.
Refer to the Flow Diagrams for the Quantum 4. Even with a perfectly adjusted supply, it is possible for a potential drop in voltage at each connection point within the daisychain.
By the time the voltage reaches the last board in the daisy chain, and all of these potential voltages drops are considered, the combined drop can be such that. The range for this voltage is not critical at the Quantum 4 main board, and the reading does not need to be taken there. Extreme care must be observed when taking any readings, as or VAC depending on incoming system voltage is present within the power supply.
Adjusting the supply requires the use of a small screwdriver with an insulated shaft refer to NS inserted into the supply to access an adjusting potentiometer.
It is possible for the screwdriver and the person making the adjustment to come into contact with potentially lethal voltages. To isolate the problem: 1. Unplug the DC power connector from the power supply. Turn the Control Power switch back ON. Measure the voltages on the DC power output connector of the power supply as shown at the end of this section. If the proper voltages are present, the problem is external to the power supply, and further troubleshooting should be performed. If there are NO DC voltages present, then the problem could be that the internal power supply fuse is blown.
To access and replace this fuse, please follow these instructions: 1. Remove the AC and DC power connectors from the power supply. The power supply is mounted to a plate. Remove the four mounting plate nuts one from each corner. Remove the three Philips head screws located on the bottom of the power supply, and two on the side. Carefully lift of the slotted cover. This will expose the circuit board, as shown here:. Locate the fuse on the circuit board from the above drawing. It is mounted in a clip.
Pry up on one end of the fuse and extract the fuse. Verify that the fuse in question is actually bad, and if so, replace the bad fuse with a known good one. This fuse is rated for 3. Reassemble the power supply in the reverse order that it was disassembled. Mount the power supply on to its mounting plate. Reattach the AC and DC power harnesses. Turn the Control Power switch to ON. Verify that DC voltages are now present on the DC power connector.
The 5 VDC may now be adjusted per the adjustment procedure on the following page. Ensure that all of its connectors are tight. If all connections are good, then go back and start measuring over again, this time beginning at the rst board in the daisy chain. Continue checking the voltage at each connection, until you locate the point at which the voltage drop is excessive. This will usually indicate a connection that is not being made properly, or the sockets within the connector are weak.
Measure directly at the last connection. If the voltage is low, ensure that there is not an excessive voltage drop in the daisy chain. If the voltage is out of range, then the supply itself may need replaced. The VDC may be measured the same as the other voltages, however, this voltage is not adjustable on any supply, so if the harness is not the culprit, the supply may need to be replaced. This is because the graphics required to create this screen will draw more current than when the screen is showing the normal POST style messages during a boot up.
Ensure that the meter is set to the proper range DC, V or equivalent , as well as observing proper wire polarity. If the reading is outside of this range, then using a thin, at bladed, insulated screwdriver, insert the tip into the access hole for the appropriate voltage potentiometer refer to the diagram on the following page for adjustment location.
Adjustment should only be performed by qualied personnel, using an insulated screwdriver. While watching the DVM, slowly rotate the screwdriver blade clockwise to increase the voltage or counter-clockwise to decrease.
When ordering this replacement, you will receive an upgrade kit. Refer to the Recommended Spare Parts list for the upgrade part number. Specific units may or may not have both Digital and Analog boards, depending on options. Additionally, the power supply may vary. Each channel that is used needs a module plugged into it. A yellow module indicates that it is used for Inputs.
A black module is used for Outputs. The standard Quantum LX compressor control can have up to two Digital boards depending on options. These LED's should be ashing at a high rate during normal operation. This indicates that the main board, and the Digital board that you are looking at, are properly communicating with each other. If these switches are not properly set, the result will be lost or failed communications, or the wrong outputs being energized, or the wrong inputs being received.
Another connector plugs into the power supply. The remaining four connectors pin will plug into each of the Digital and Analog boards in the system. All wires in this harness are blue in color. Therefore, any time that a connector is unplugged from the daisy chain, these voltages and signals cannot continue through the daisy chain to the next board.
The four wires that feed from the power supply to the Quantum 4 provide all of the necessary D. These two signals are the RX receive and TX transmit. A second pin connector plugs into PL14 of the Quantum 4, where the communications signals originate. Another connector plugs into the power supply and picks up the DC voltages that are used. The remaining four connectors pin will plug into each of the Digital and Analog boards in the system up to four total.
This harness varies from the Special panel harness in that. To connect these boards together so that the Quantum LX can control them, they must be interconnected with a wiring harness that provides all of the necessary D. This harness uses Red, Blue, Yellow and Purple wiring. Q5 Panel - This harness distributes power and communications from the terminal blocks to the various logic boards. The harness terminates with four, 16 pin connectors, which plug into the digital and analog boards, and two, 4 pin connectors that apply DC power to the Q5 and Interface boards.
If the power LED is not lighted, check the cable for proper connectivity. Note: Each board provides the necessary connections to feed all signals to the following connectors. If the auxiliary Analog or Digital Board is not present then a jumper plug see Recommended Spare Parts List must be installed to daisy chain the signals.
This LED does not indicate however that the proper voltage is necessarily present at the board, only that the voltage is enough to energize the voltage sensing circuitry. If a voltage related problem is suspected with regard to a Digital Board, the only way to actually determine this is to read the voltage on a Digital Voltage Meter DVM.
Notice that the Digital Board has one of these connectors on both ends of the board. The software program within the Quantum LX is constantly looking at these Input channels, via communications, and based upon whether a control voltage is present or not, will provide the necessary control for an associated Output channel.
For instance, if a control voltage is present on the Oil Level Sensor input, the software will determine that the Separator has sufcient oil level for the oil heaters to be energized if the temperature of the oil is also sensed to be low. Temperature sensing will be discussed in the Analog Input section. There are two possible varieties of Digital Input modules used on standard compressor control packages. One is for Volt controls, and the other is for volt controls. Both of these module styles are yellow in color.
A side prole of these modules is shown below:. The voltage will need to be corrected for proper operation of the system. The cause for a low voltage reading could be: The power supply may need adjustment see the section on power supplies. These Input modules, can be identied as to their operating voltage by looking at either the side, as shown above, or from the top.
You will notice the module operating voltage printed on the top, and the voltage range printed on the side. An LED is associated with each module and displays the state of each module.
If the LED is not lit, then check the fuse. If the fuse is OK, then check the module. Power off the panel. Open the panel door. Remove the questionable fuse. Power on the panel. Check the LED on the tester. If the fuse is faulty, check for external shorts on the corresponding circuit, the replace the fuse with a new plug-type fuse refer to Recommended Spare Parts list. Never plug a Volt Input module into a Volt system, and vice-versa.
Never plug an Output module into a position designated for an Input module. You will notice that when a module is plugged into the Digital board, there is a fuse located directly adjacent to the module. This fuse is of the pluggable variety, and must be plugged into the IN position for an Input module. These devices include solenoids, relay coils, and heaters to be energized, based upon the logic within the Quantum LX software program.
There is one variety of Digital Output modules used on standard compressor control packages. This one module will handle both Volt controls, and volt controls. This module is black in color. A side prole of this module is shown below:. Never plug an Input module into a position designated for an Output module. You will notice that when a module is plugged into the Digital Board, there is a fuse located directly adjacent to the module.
This fuse is of the pluggable variety, and must be plugged into the OUT position for an Output module. Position 3 provides power and position 4 is a neutral on the DIO connectors.
Positions 1, 2, 5, and 6 are signal connections, as shown below:. Replace the questionable module. If it is an Output module, check for proper panel voltage on the DIO connector plug. Check the voltage between position 4 neutral and the associated position to the Output module. If it is an Input module, check if the associated LED is on when power is applied to the module. Make sure the LED associated with the Output is on when power is applied to the module. If the LED is not on when it should be and there is no operating condition preventing it, contact the Frick Service Department.
Check the voltage between the position 4 neutral and the associated position to the Output module. If the voltage is OK, check for proper panel voltage between the associated position to the Output module on the DIO connector and the associated position on the terminal strip. If the voltage is OK, check the wiring external to the panel.
If voltage is not OK, check the fuse. If the fuse is OK then check the module. If the module is OK, check for proper panel voltage on the DIO connector plug between position 3 Hot and position 4 neutral. Shut off control power. Remove the old board from the machine and the new board from its packing and place both on an anti-static surface.
Check that all jumpers, dipswitches and components are properly setup on the new board as it was on the old board refer to the Digital Settings tables near the end of this section.
Install the modied replacement board in the panel. Make sure the LED associated with the Input is on when power is applied to the module. If the LED is on then the fuse and Input module are good. If the LED is on and there is no input voltage, replace the Input module.
If the LED is not on when power is applied, check the fuse. If the fuse is good, replace the Input module. If you are receiving an Alarm or Shutdown from a digital input in which the adjacent LED indicator light is on, check the Service Screen to see if that channel is turning on and off. If so, replace the input module. This selection provides a method to detect all connected Digital and Analog boards. If a board has been removed, a communication error shutdown will be issued until this key is selected.
The About screen will show what was detected. No termination. No pull-up. RS transmit pull-up for long communications lines. No pull-down. Click on the [OK] button to proceed.
If the communications is working properly, there should be an immediate response from the first Quantum. If this portion of the test has passed, you can try to communicate to the next or any Quantum , by changing the value that you type into the HyperTerminal screen as follows: You will now be back to the main Hyperterminal communications screen.
This screen will be blank. All communications, both from the computer, and to the computer from the Quantum , will appear on this screen. Proceed to the Testing Communications section. Instead of [ 01], replace the 01 portion with the ID that you would like to access.
For instance, if you wanted to talk to a fourth Quantum ID 4 , type in [ 04]. This should return a message from that Quantum. This has been just a brief description of how to check your communications and verify that it is working. Greater detail can be found by consulting tables for each of the protocols in this manual. General Notes Ensure that the Quantum communications parameters are correct.
This setup can be found on the Communications screen. This info must match that of the device that you are trying to talk to at the other end. Ensure that neither of these LEDs are on continuously.
If one or the other or both are on constantly, disconnect the Com cable. If the status of the LEDs does not change, check the wiring connections to the comm port. Ensure that the wiring is not backwards. If the wiring is correct, power the Quantum down, then back up. If either or both of the LEDs is still on, a bad driver chip may be suspected on the Quantum, and the board should be replaced. Once everything has been inspected cables, jumpers, and setup , try to develop communications from the master.
If nothing happens, it would be best to consult the HyperTerminal section of this manual for more detailed troubleshooting. If no data appears, or if the data does not match the specific protocol requirements that you are using, then check the following:.
Verify that the communications wiring matches that shown in the drawings at the end of this manual. Access the Communications screen and. Also, check that the baud rate matches that of the setup in the properties section of the Hyperterminal example. Verify the position of the jumpers by comparing them with the section entitled Quantum Communications Jumpers. Ensure that the data that you have entered in Hyperterminal, exactly matches the example.
Go back through the Setting up Hyperterminal section, and ensure that it has been followed exactly. Repeat the process if necessary. If you are using a converter card to convert the RS signal from the computer to RS or RS , then either verify that the converter card is working properly with a different piece of known functioning equipment, or eliminate it completely by tying into the Quantum directly through RS Quantum 4 only.
The Communications port on the computer is bad. Try to verify this by communicating to a different piece of known good equipment. This table also shows the Data Table names, as well as the page numbers within this manual that the pertinent Data Tables may be found:. Leaving Temp. However, being that one decimal place is assumed, a value of 10 actually needs to be sent. Note 3: Mode must already be enabled. Note 4: The value passed with this command is the position percentage to which the control will attempt to set the Slide Valve.
This command is reset by a Remote Load or Remote Unload command Note 5: The value passed with this command is the speed percentage to which the control will attempt to set the Drive.
The numeric value to the left of each message corresponds to the value that is read from the Safety Message addresses Frick address As an example, if Frick address were being read, and it returned a value of 51, then referring to the chart on the following pages, it would be found that the code of 51 represents Oil Level Shutdown. The processor board shown on this page is known as the Q5 board, and it is based on the Pentium microprocessor platform.
The operating software that this board runs is known as Quantum LX software. This software displays graphic information and data on the LCD screen in a format that is similar to the way a Windows desktop computer screen displays a Web browser the Internet.
The Q5 board can be identified by the presence of a large aluminum heat sink located on the board. Adjacent to the processor board, is an Interface board which allows the user to attach local communications connections via the four orange connectors RS and RS ports.
There are also a number of jumpers present on both the Q5 and the Interface board. These jumpers MAY need to be modified by qualified personnel to config-. The Q5 utilizes Flash Card technology. There is a Flash Card socket located on the under side of this main board. The Q5 board has the LX Operating System pre-loaded at the factory, so this Flash Card feature will primarily be utilized for future program updates.
The information that follows will primarily describe the jumper configuration for communications settings, as well as wiring diagrams for the different types of communications that are possible with the Q5. As mentioned in the previous paragraph, the user connections for the serial communications portion of the Q5 controller consists of an Interface board, mounted below and to the right of the main controller.
In addition to external forms of serial communication to be discussed shortly , the keypad also connects here: COM-3 RS They can be used for external communications to the outside world.
The Interface board was developed to make customer connections to the processor easier, as the Q5 use connections that are too small and delicate to easily utilize in the field. The following table describes the Interface board RS connector pinouts and their associated communications signals:.
Always ensure that the wiring matches these pictorials before proceeding. Typically, the termination jumper should be installed in the last Quantum in the communications daisy chain only. If pins are shorted closed on J1, then RS is selected. Notice also the two LED indicators that are pointed out.
Also verify the position of J1, and ensure that it is set for pins closed. If pins are shorted closed on J7, then RS is selected. Also verify the position of J7, and ensure that it is set for pins closed.
Notice also the two LED indicators that are pointed out in the figure. If D43 never flashes, then the LX is not receiving any data. If D43 does flash each time a data bit is received, but D42 never flashes, this may indicate that the LX has received a data command, but that the protocol package is not properly formatted, and the LX cannot respond.
It can still be diagnosed with the following procedure. If D54 does flash each time a data bit is received, but D55 never flashes, this may indicate that the LX has received a data command, but that the protocol package is not properly formatted, and the LX cannot respond. The following user selectable buttons are provided:. This screen allows the technician to view all of the serial communications information that the Quantum LX is receiving and transmitting, one port at a time.
Simply select the button at the upper right side of the screen that corresponds to the port that you wish to view. The selected port name in this case Comm4 will appear in the upper left side of the screen. Each time a new command is sent or received, the screen will need to be refreshed by selecting the [Show CommX] button where X is replaced with the comm port number. Refer to the section on Hyperterminal for some examples of how this screen may be used.
The following user selectable button is provided:. This screen allows the technician to view all of the Modbus TCP communications information that the Quantum LX is receiving and transmitting. The processor board shown on this page is known as the Quantum 4 board, and it is based on the Pentium microprocessor platform.
The Quantum 4 utilizes Flash Card technology, as did the Quantum 3. The Quantum 4 board has the LX Operating System pre-loaded at the factory, so this Flash Card feature will primarily be utilized for future program updates. When calling Frick Company for service or help, it will greatly assist us if the type of board is known, either Quantum 1, 2, 3 or 4.
Additionally, Frick will request the Sales Order number, and the Operating System version number this can be found on the About screen. The more information available at the time of the call, the better able we will be to assist you. The Quantum 4 board can be identified by the presence of a daughter board mounted to the main board. This daughter board is the communications portion of the Quantum 4, and it can be identified by the presence of an 8 position DIP switch.
There are also a number of jumpers or links present on this smaller board, as well as three green connectors RS, RS and RS ports. The jumpers are used to set up the communications parameters that are listed on the next page. The information that follows will primarily describe the jumper configuration for communications settings, as well as wiring diagrams for the different types of communications that are possible with the Quantum 4.
The main board larger of the two has a number of jumpers or links also. It can be used for external communications to the outside world. TB2 is known as Com However, TB3 is also known as Com TB2 can be used in the same manner as TB1. The Com-1 and Com-2 serial communications portion of the Quantum 4 controller consists of a daughter board, mounted to the main controller. In addition to external forms of serial communication to be discussed shortly , the keypad also connects here.
Com-3 is another serial port RS that is dedicated to providing communications to the DIgital and Analog boards. The location of Com3 is on the main processor board and will be explained in the section entitled Com-3 Description. These signals must first be conditioned converted.

LK11 must be set to the A position. Notice the LED indicators that are pointed out. Also verify the position of LK11, and ensure that it is in position A. If communications cannot be established using PL6, verify that the wiring is per the figure when wired direct from a remote RS port.
Notice also the two LED indicators that are in the figure. If D2 never flashes, then the LX is not receiving any data. If D2 does flash each time a data bit is received, but D3 never flashes, this may indicate that the LX has received a data command, but that the protocol package is not properly formatted, and the LX cannot respond.
On the Communications Setup screen, verify that the proper Panel ID, Baud rate, data bits, and protocol matches that of the initiating device. If D6 never flashes, then the LX is not receiving any data.
If D6 does flash each time a data bit is received, but D1 never flashes, this may indicate that the LX has received a data command, but that the protocol package is not properly formatted, and the LX cannot respond. On the Communications Setup screen, verify that the proper Panel ID, Baud rate, data bits, and protocol has been setup, and matches that of the initiating device.
If D2 flashes each time a data bit is received, but D3 never flashes, this may indicate that the LX has received a data command, but that the protocol package is not properly formatted, and the LX cannot respond.

The possible messages are: Off - No communications are currently taking place. Active - Valid communications are actively occurring. This could be due to a bad checksum value, a wiring issue, or hardware problem at either the transmitting host or receiving Quantum LX end.
A pull down menu is provided to select from the following: Data Bits - Determines the number of bits in a transmitted data package. A pull down menu is provided to select from the following: 1 2 Parity - In communications, parity checking refers to the use of parity bits to check that data has been transmitted accurately.
A pull down menu is provided to select from the following: None Even Odd Protocol - A protocol is the special set of rules that each end of a communications connection use when they communicate.
A pull down menu is provided to select from the following: No - Do not use map file. The possible displayed states are: Off - Loss of or intermittent communica- Failed - Loss of communications, a shutdown message will be generated. The information in a message command requires: 6.

Command structure: Description Start of command sequence. Local Node: Quantum ID Octal Allen-Bradley Data Access Data passed to and from the Quantum are integer values with one decimal field assumed unless shown otherwise or the command is sent to select two decimal fields. D0 The greater effective char- acter density increases throughput over ASCII mode at the same baud rate.
The Response If the Quantum makes a normal response, the function code in the response is an echo of the This represents a heads up alert that data is coming: Following the last transmitted character, a similar interval of at least 3. In this particular example, we are strictly looking to write a data value, so we will be performing a write function 06 : Since this is the only address we are interested in writing to, send the following message: This is accomplished by adding each of the byte pairs hex that we have generated thus far: T1-T2-T3-T4 01 03 From the previous paragraph, we can assume that there is one decimal place to be applied to the data value that was returned.
Value The returned value in the above example is hex. Turn on the power for the lap top. After the laptop has fully booted, locate the Hy- A new dialog box will be shown asking to select a Com port choose the Com port that your communications cable is attached to, this will normally be Com If no data appears, or if the data does not match the specific protocol requirements that you are using, then check the following: Verify that the communications wiring matches that shown in the drawings at the end of this manual.
Access the Communications screen and verify that the Quantum ID is set to the same value that you are trying to access. The Communications port on the Quantum is bad. Oil Pressure Warning 11 Missing Comp. Oil Temperature Shutdown 25 High Comp.
Oil Temperature Warning 26 Low Comp. Oil Temperature Shutdown 27 Low Comp. On the Communications Setup screen, verify that the proper Panel ID, Baud rate, data bits, and protocol has been setup at the Quantum LX, and matches that of the ini- tiating device.
The following user selectable buttons are provided: [Show [Show [Show [Show Comm1] Comm2] Comm3] Comm4] This screen allows the technician to view all of the serial communications information that the Quantum LX is receiving and transmitting, one port at a time. The following user selectable button is provided: [Refresh] This screen allows the technician to view all of the Modbus TCP communications information that the Quantum LX is receiving and transmitting.
Data Bits: Does not matter, but all Comms to be tested must be set the same. Stop Bits: Does not matter, but all Comms to be tested must be set the same. Parity: Does not matter, but all Comms to be tested must be set the same.
