3. Error codes
The internal microcontroller continually monitors several voltages and signals and checks proper
operation of the sensor-transmitter measurement system.
If an error occurs, a fault code is displayed on the transmitter display. Error codes, which occur im-
mediately after initial installation, are usually caused by incorrect electrical wiring or improper flow
sensor installation (i.e. sensor tubes not totally filled with liquid).
A transmitter, which is not properly wired to the flow sensor, will indicate error code number 2 (ERR
2).
Possible error codes are:
Code Display Description
Err 1 Drive Drive signal error. Drive amplifier gives maximum power
possible causes:
• extreme unbalanced vibrating sensor system (for instance: gas
bubbles in the pipe loops or pipes are not filled completely)
• drive coil (term 1 - 2) defective
Err 2 Pick-up One of the two sensor signals 1 or 2 is not correct
possible causes:
• the wiring is incorrect
• one or both coils defective
• defective component on safety or amplifier board
• Sensor is not moving
Check sensor and wiring according to trouble-shooting section.
