What causes incorrect current output signal from Endress+Hauser Liquiline CM442R?
- M
  Megan SkinnerSep 12, 2025
  If the current output signal from your Endress+Hauser Controller is incorrect, measure the load and reduce it to the permitted value if necessary, referring to the Technical data in the Operating Instructions under "Commissioning", as the total load in the current loop might be too high. Also, check the wiring and identify and eliminate the cause of interference, as EMC (interference coupling) may be the cause.

Why is there no current output signal from my Endress+Hauser Liquiline CM442R?
- Z
  Zachary GreeneAug 22, 2025
  If there's no current output signal from your Endress+Hauser Controller, it could be due to a defective base module. Verify this by using the integrated current simulation and connecting an mA meter directly to the current output.

What to do if Endress+Hauser Liquiline CM442R Controller display doesn't change or device cannot be operated?
- K
  Kimberly WilliamsAug 25, 2025
  If values appear on the display of your Endress+Hauser Controller, but the display isn't changing or the device is not operating, it could be due to: * Incorrectly wired module: Check the modules and wiring. * Impermissible operating system condition: Switch the device off and then on again.

Why is the display dark on my Endress+Hauser Liquiline CM442R Controller?
- L
  Laurie ThomasAug 26, 2025
  A dark display on your Endress+Hauser Controller (if equipped with the optional display) can be caused by: * No supply voltage: Check if supply voltage is applied. * Display connector plugged in incorrectly: Ensure it's in the RJ45 socket on the base module. * Defective base module: Replace the base module.

What to do if Endress+Hauser Transmitter display does not change or the device cannot be operated?
- Q

  If the display values are present, but the display doesn't change or the device is inoperable, there might be an issue with the module wiring. Check the modules and wiring to ensure they are correctly connected. Alternatively, the device might be in an impermissible operating system condition. To resolve this, switch off the device and then switch it on again.

  If the display is dark, it could be due to several reasons. First, check if the supply voltage is applied. Second, verify that the display connector is correctly plugged into the RJ45 socket on the base module. Finally, the base module itself might be defective, in which case, replace it.

How to fix a fixed current output signal on Endress+Hauser Liquiline CM442R?
- A
  Alyssa SmithSep 18, 2025
  If the current output signal from your Endress+Hauser Controller is fixed, switch off the simulation, as the current simulation may be active.

Why is there no current output signal from Endress+Hauser Controller?
- J
  Joseph AllenSep 14, 2025
  If there is no current output signal from your Endress+Hauser Controller, disconnect the cable and measure directly at the device, as the cable may be disconnected or short-circuited. If the cable is not the issue, consult the "Device-specific errors" section, as the output may be defective.

Why measuring chain slope cannot be adjusted on Endress+Hauser Liquiline CM442R?
- K
  Kimberly SanchezSep 12, 2025
  If the measuring chain slope on your Endress+Hauser Controller cannot be adjusted, is too low, or shows no slope, check the device directly, as the device input may be defective. If the device input is not defective, the sensor might be old and needs to be renewed. Another possibility is a hair-line crack in the glass membrane, which also requires renewing the sensor.

What causes fluctuations in the measured value on Endress+Hauser Liquiline CM442R Controller?
- R
  rodriguezlisaSep 6, 2025
  If you observe fluctuations in the measured value on your Endress+Hauser Controller, check the cable routing for any interference on the signal output cable, and route the cable separately if necessary. Additionally, there may be interference potential in the medium, so try to eliminate the source of interference or ground the medium as close as possible to the sensor.
