limit
Check process conditions. Adjust the parameter value
'Lower alarm limit' to normal process conditions.
148
Transmitter electronics
temperature too high
Decrease the ambient temperature. If possible, reposition
the device in a different location. Inspect the device for
heat-related damages.
149
Transmitter electronics
temperature too low
Increase the ambient temperature. If possible, reposition
the device in a different location. Inspect the device for cold-
related damages.

153
CH1 loop current in lower
saturation
The process value is so low that the loop current reaches
the lower saturation limit and cannot decrease any further.
Check process conditions. Adjust parameter value 'Lower
range value'.
154
CH1 loop current in upper
saturation
The process value is so high that the loop current reaches
the upper saturation limit and cannot increase any further.
Check process conditions. Adjust parameter value 'Upper
range value'.
155
CH1 loop current error
Invalid loop current deviation detected. Check current out‐
put cable connection. Passive operation: check external
power supply.
