To Next PageTo Next PageWhat should I do if my Siemens Transmitter is out of specification?
If the Siemens Transmitter detects deviations from permissible ambient or process conditions, it indicates that the measured value is unreliable, or deviations from the set value in the actuators are likely greater than anticipated. To resolve this, check the ambient temperature or process conditions. If possible, install the device at a different location.
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 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.
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 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.
