Interface error
M030.020
Exchange of non-critical data between sensor and electronics is
precluded due to problem in the transmitter circuit of the electronics
or in receiver circuit of the sensor
GOOD Maintenance Required GOOD Maintenance Required

memory burn
error
M026.024
Writings to the electronic Non-Volatile Memory were not successful.
The device continue to work without problems but after the next
power cycle the last configuration will be lost

Sensor Invalid F120.016
The transducer is not in condition to generate a valid signal due to
one of the following conditions:
- The primary signal of the sensor is no longer available
- The sensor and the connected electronics are incompatible
BAD Maintenance Alarm More Diagnostic Available BAD Sensor failure
Sensor Memory

F118.017
The data in the sensor memory are corrupted precluding the correct
functionality of the device
BAD Maintenance Alarm More Diagnostic Available BAD Sensor failure
P-dP Sensor Fail F114.000
The sensor signal value is incorrect due to a mechanical failure i.e.
Loss of fill fluid from the cell; ruptured diaphragm, broken sensor….

error
M028.018
Writings to the Sensor non-Volatile Memory were not successful. The
device continue to work without problems but any replacement
operation is compromised because the back-up configuration is not
updated
