Why is my Endress+Hauser Liquiline CM44P display dark?
A dark display on your Endress+Hauser Controller can be due to several reasons: a lack of supply voltage (check if supply voltage is applied), the display connector being plugged in incorrectly (it must be in the RJ45 socket on the base module), or a defective base module (replace the base module).
What to do if the Endress+Hauser Liquiline CM44P displays values but doesn't change or operate?
If your Endress+Hauser Controller displays values but the display doesn't change or the device cannot be operated, it could be due to incorrect module wiring (check modules and wiring) or an impermissible operating system condition (switch the device off and then on again).
What to do if Endress+Hauser Liquiline CM44P Controller shows invalid measured value?
If your Endress+Hauser Controller is showing invalid measured values, you should first check the sensor power supply and then restart the device.
How to troubleshoot implausible measured values on Endress+Hauser Liquiline CM44P?
If you are getting implausible measured values on your Endress+Hauser Controller, the inputs may be defective. Connect the Memocheck Sim CYP03D to the input to check its function.
What causes update error in Endress+Hauser Controller?
An update error on your Endress+Hauser Controller might happen because the firmware update failed. You can try repeating the update. If that doesn't work, the SD card may have an error, so try using another card. Finally, the firmware might be incorrect, so repeat the process with suitable firmware.
Why Endress+Hauser Liquiline CM44P Controller showing incorrect current value?
An incorrect current value in your Endress+Hauser Controller's current output can be caused by incorrect adjustment (check with integrated current simulation, connect mA meter directly to current output), a load that is too large, or a shunt/short to ground in the current loop.
Why Endress+Hauser Controller has no current output signal?
If there is no current output signal from your Endress+Hauser Controller, the base module might be defective. Check with integrated current simulation and connect an mA meter directly to the current output.
What causes firmware failure in Endress+Hauser Liquiline CM44P?
A firmware failure in your Endress+Hauser Controller is due to an internal device error. Update the software.
What to do if Endress+Hauser Controller electronics module is defective?
If the electronics module in your Endress+Hauser Controller is defective, replace the module.
How to fix no measurement signal from sensor in Endress+Hauser Liquiline CM44P?
If your Endress+Hauser Controller is not receiving a measurement signal from the sensor, check the sensor connection and check the sensor, replace it if necessary.
