• 1. When the Quantum/Quantum LX panel comes out of screensaver or at other random times, the panel reboots. How do I fix this problem?
• Verify that the +5Vdc power supply voltage is set high enough. Consult the power supply section in the Maintenance Manual for instructions on checking and changing the +5Vdc power supply voltage.
• 2. On a Quantum LX panel, how do I access other User Levels beyond 0?
• The default password for User Level 1 is 10, and the default password for User Level 2 is 20.
• 3. Someone has changed the User Level passwords on the Quantum LX panel. How do I login to a higher User Level?
• Contact Frick Controls and we can give you a temporary password that will allow you to login to that User Level and change the password to another value.
• 4. I am trying to setup serial communications to the Quantum/Quantum LX panel, but the panel is not responding. How can I verify that the communications port is working?
• Test the communications port using the Communications Loopback Test to verify that the port is working. The instructions for performing this test can be found in the Communication Manual. (The Communications Loopback Test was first available in Quantum LX Version 6.09 and in Quantum Version 5.00.)
• 5. When a compressor has shutdown, the Quantum/Quantum LX panel displays a shutdown message, but I don't know what the shutdown message means. Where do I find a definition for the compressor shutdown message?
• In the Operation Manual is a list of all the Quantum/Quantum LX alarm and shutdown messages and a description of the conditions that cause each alarm or shutdown.
• 6. I have 3 Quantums in my engine room right now. If I get a Quantum LX, can I sequence them all?
• The Quantums and Quantum LX can be sequenced by making one of the Quantums the master. The panels will communicate to each other through serial communications, and the remaining Quantums and the Quantum LX will act as slaves.
• 7. What is needed to sequence Quantum LXs?
• If all the panels are Quantum LX panels, the panels must be connected by an Ethernet network before they can be setup for sequencing. The Quantum LX panels use the Ethernet network to exchange setpoints and transmit sequencing commands.
• 8. I have Quantums which I view remotely using Q-Talk. Can I also view a Quantum LX panel through Q-Talk?
• No, to view a Quantum LX panel remotely an Ethernet connection must be used. The Quantum LX screens are viewed on a browser as a web page.
• 9. After I upgraded my Quantum LX software, I get a Low RPM Sensor Warning or some other Low xxx Sensor Warning and cannot clear the message.
• Sensor Warning messages may appear after the Quantum LX software (Version 6.53 or above) has been reloaded. These sensor warning messages are issued if the sensor reading was to the lower or minimum range (out of range) for its sensor. They are valid warnings if the analog input is defective or wired incorrectly. If the analog input is not used, it will appear as out of range. If the analog input is not used, the message can be cleared by setting the IO Board to None for these analog inputs. This will disable the alarm and clear the message. The configuration for these analog inputs (for some of the more common sensor warnings) can be found on the following Quantum LX screens (you must be in Session Level 3 to edit these values).
• 
  Low Rem Capacity Position Sensor Warning (Menu>Calibration>Motor Miscellaneous)
  Low Manifold Pressure Sensor Warning (Menu>Calibration>Pressure)
  Low Filter Pressure Sensor Warning (Menu>Calibration>Pressure)
  Low RPM Sensor Warning (Menu>Calibration>Motor Miscellaneous)
• 10. Why are my Run Hours on the Quantum LX Home screen not accumulating and/or my Maintenance Alarms are not working properly?
• If any of the setpoints for the Next Scheduled At hours on the Maintenance screen are less than the Run Hours on the Home screen, it will cause a Stop Process for the Maintenance process in the Quantum LX. This will cause the Run Hours to stop and the Maintenance Alarms not to display. An event in the Event Log will be displayed as Stop Process -Process Timeout Maintenance. To correct the problem, set the Run Hours to the correct value, set all of the Next Scheduled At hours to a value above the Run Hours and cycle power on the panel.
• 11. Can I upgrade my Quantum software to a newer version?
• You can upgrade the Quantum 4 series software with a Program Upgrade Flash Card and you can upgrade the Quantum LX series software with a Program Upgrade USB Flashdrive. Contact Frick Controls for part numbers and details.
• 12. Can I upgrade my Quantum to a Quantum LX without replacing the entire panel?
• Yes you can. Frick has a hardware upgrade kit, p/n 649C1083G01, and a software upgrade kit, p/n 649D5236G11 for that very purpose. Frick Factors can order these kits directly from the Baltimore Parts Center or contact Frick Controls for more details.
• 13. Where can I find part numbers for the Quantum panels?
• You can find replacement part numbers for the Quantum in the Quantum Maintenance manual, S90-010 M and for the Quantum LX in the Quantum LX Maintenance manual, 090-020 M.
• 14. Sometimes when I press a numeric key on the Quantum LX keypad, I get the wrong character.
• This may be due to the Shift key being stuck. Press the Unload key momentarily and try the numeric keys again. If it continues to display the incorrect character, it may be another problem. Contact Frick Controls for more troubleshooting.
• 15. When I look at the Slide Valve position on the Quantum Calibration screen and on the Home screen, the two values do not match. Why is this?
• The Slide Valve position displayed on the Quantum and Quantum LX Calibration screen is the actual Slide Valve position, based on the slide valve total amount of travel. The Slide Valve position displayed on the Home screen is a calculated value, based on the limited amount of travel due to the Slide Stop position.
• 16. I have heard you can view the Quantum LX screen remotely from a PC. How do I do this?
• The Quantum LX has built in Web Browser software. If the Quantum LX is connected to a network and your PC has access to that network, you can view the Quantum LX by selecting the network IP address of the Quantum LX from your web browser (ex: Internet Explorer). In addition to viewing, you can edit setpoints, save setpoints and control the compressor operation.
• 17. I had my compressor rebuilt. Originally it had a slide valve potentiometer. After the rebuild it has a linear transmitter. How do I make this work?
• The wiring at the Quantum Analog board for the slide valve transmitter should be the same as the potentiometer. Depending on the Analog board type, the Quantum configuration or the Analog board jumpers will need to be changed to correctly read the transmitter. You can find the wiring diagram and jumper configuration for the analog board in the latest version of the Quantum or Quantum LX Maintenance manual and the software configuration in the latest version of the Quantum or Quantum LX Operation manual.
• 18. Can I print the data from the Quantum LX Trending screen?
• You can upload (save) the Trending Data files to a USB Flashdrive and view or printout the files from your PC. The files are in a .csv file format and can be viewed from a program like MS Excel. The upload option is on the Quantum LX Trending Setup screen.
• 19. Can I save the data from the Quantum LX Event Log?
• You can upload (save) the Event Log, Alarm History, Freeze Screens and Trending Data files to a USB Flashdrive and view, save or printout the files from your PC. The Event Log and Alarm History are text files and can be viewed with a word processor. The Freeze screens can be viewed with your PC Web Browser and the Trending Data files are in a .csv file format and can be viewed from a program like MS Excel. The upload option is on the Quantum LX Diagnostic screen.
• 20. How are the VFD setpoints on the Motor Setpoint screen used to control the capacity?
• Refer to the Quantum LX Operation manual, 090-022 O, for a detailed description of the VFD operation and the explanation of the setpoints used to control compressor speed and capacity. You will find this under the Setpoints Motor(VFD) section of the manual.
• 21. How can I find and change the Ethernet IP address on my Quantum LX?
• The Ethernet IP address, as well as all the Ethernet communication setpoints can be found in the Quantum LX Menu at Configuration>Ethernet.
• 22. My Quantum screen is black, but the compressor is running. What is wrong?
• Several things could cause this symptom. The most likely are, you could have a problem with the LCD display, the LCD display inverter module or the backlight tube for the display. The backlight tube provides the light for the LCD display. The inverter module provides the supply voltage to the backlight tube. Refer to the Quantum Maintenance manual, S90-010 M or the Quantum LX Maintenance manual, 090-020 M for the troubleshooting guide. You will find this under the What If The Operating Status Screen Is Not Shown section.
• 23. my Quantum LX communicate via Ethernet to my PLC?
• The Quantum LX will communicate via Ethernet using Modbus TCP or Ethernet/IP protocols. The Ethernet communication setpoints can be found in the Quantum LX Menu at Configuration>Ethernet. Detailed information regarding the Quantum LX Address ranges that are available to the PLC can be found in the Quantum LX Communication Setup manual, 090-020 CS.
• 24. The pressure or temperature analog value on the Quantum LX display fluctuates, but the actual values are steady.
• The most common faults with the improper reading of the analog channels other than a hardware problem (analog board) or a software setup problem is one of the following: a sensor fault, a wiring problem or improper grounding of the system. Refer to the Quantum LX Maintenance manual, 090-020 M, section: Analog Boards / Troubleshooting the Analog Inputs and Outputs.
