Diagnostics and troubleshooting

In the event of faults during commissioning or operation of the device, you can carry
out fault diagnostics on the electronic insert. This function is supported by the
electronic inserts FEI51, FEI52, FEI54, FEI55.
The electronic inserts FEI53, FEI57S and FEI58 signal two types of faults:
• the red LED flashes - faults that can be rectified
• the red LED is lit continuously - faults that cannot be rectified
8.1 Activating fault diagnostics FEI51, FEI52, FEI54 and
FEI55
The diagnostics provide information about the operating status of the device. The
results of the diagnostics are displayed by LEDs. If the diagnostics detect multiple
faults, these are shown according to their priority. A serious fault (e.g. priority 3) is
always displayed before a less serious fault (e.g. priority 5).
