If your Siemens Transmitter shows INVALID CFG PARAM, it indicates that the factory settings for Functional Safety are faulty. Replace the device.
What to do if Siemens Transmitter failure occurs due to "Out of service" mode?
If the Siemens Transmitter output signal does not represent the process value because the device mode is set to "Out of service", you should disable the "Out of service" mode and enable normal operation.
How to fix invalid device configuration on Siemens SITRANS P420 Transmitter?
If the Siemens Transmitter has an invalid device configuration because one or more parameters are set to invalid values, review the configuration values and adjust as necessary.
What to do if the Siemens SITRANS P420 is in function test mode?
If the Siemens Transmitter output signal is temporarily invalid because work is being performed on the device, use manual mode over HMI or disable the engineering system.
Why is my Siemens SITRANS P420 Transmitter showing 'Maintenance required'?
If you receive a 'Maintenance required' notification for your Siemens Transmitter, it means the output signal is still valid, but wear reserve is almost exhausted, or a function will soon be limited. It is recommended to schedule maintenance as soon as possible.
What does INVALID CFG LOOPT mean on my Siemens Transmitter?
INVALID CFG LOOPT on your Siemens Transmitter indicates that the loop current is fixed because loop test or multidrop mode are enabled. To return to normal operation, disable the loop test or multidrop mode.
What to do if the Siemens Transmitter display is empty and there are no transmission pulses?
If the Siemens Transmitter display is empty and there are no transmission pulses, the cause may be no or incorrect supply voltage. Check the voltage at the terminals, the connections, and the wiring.
Why does my Siemens Transmitter display "#####" instead of the current measured value?
If the Siemens Transmitter displays "#####" instead of the current measured value, it means that the value is too large to appear on the display. Adjust the unit so that a lower value can be displayed, for example, by selecting bars instead of millibars.
What to do if Event counter 1 Number overruns above threshold Maintenance alarm on Siemens SITRANS P420?
The 'Event counter 1 Number overruns above threshold Maintenance alarm' on your Siemens Transmitter indicates that the number of overruns of the process value, which is set in the 'Upper limit' and 'Monitored value' parameters, has reached the specified threshold. To resolve this, reset and acknowledge the event counter, then check the process conditions and verify the limit monitoring and event counter settings.
What to do if Siemens SITRANS P420 Transmitter is in safety validation mode?
If the Siemens Transmitter is in safety validation mode, complete the functional test and confirm that it was successful in the Functional Safety wizard.
