Trouble-Shooting

The Prolevel FMC 662 provides a number of aids for setting up and operating the module
correctly. This Chapter contains the following:

•

Fault recognition system

•

Error message and trouble-shooting tables

•

Simulated operating mode

•

Commissioning replacement transmitters and probes.

•

Repairs

6.1

Fault recognition

Alarms

If the Prolevel FMC 662 transmitter recognizes a fault condition where further
measurement is impossible, i.e. an alarm:

•

the red alarm LED lights (LED 3) and the alarm relay trips

•

the limit value relays assume respond according to the setting in V1H3/V1H8.

•

the code for a diagnostic message is to be found in V9H0.

If several faults occur together, the code for the one with the highest priority is displayed.
The others can be called up by pressing the »+« or »-« key when field V9H0 is selected.

If the cause of the fault is rectified, its code is no longer displayed:

•

the code for the last fault rectified is retained in V9H1

•

this message can be cleared by pressing the »E« key.

If the power fails, all relays de-energise.

Warnings

If the Prolevel FMC 662 transmitter has detected a fault condition where further
measurement is possible, i.e. a warning:

•

the red alarm LED flashes but the transmitter functions as normal, however,
depending on the fault the measured value may be incorrect

•

the alarm relay remains energised

•

the appropriate code is to be found in V9H0.

The codes and error messages are listed in Table 6.1 in the order of their priority.
