6 Diagnosis and Troubleshooting
6.1 Alarms
Output on alarm
The following response is set in the factory:
If the FEC 12 detects a fault, then the current output is set to 22 mA (=110 %) to
enable process control systems to, e.g. assume a response.
Alarm indication
If no alarm indication is to be given on an alarm, then "
CONTINUE"
can be set. In this
case the FEC 12 continues to measure although the measured value is possibly
incorrect.

6.2 Simulation
Simulation enables the current value coming from the electronic insert to be
simulated. It can be used for checking the correct processing of probe signals, e.g. in
a process control system. Simulation may also be necessary for tracing faults. No
change in level is required to produce a different current value. The various types of
simulation
•
Level (

•
Volume (

•
Current (

are independent from one another and therefore none affects the others.
Note!
•
If simulation is activated, Warning E 613 is displayed to indicate this.
•
The full simulation range is only available with a free probe, only a limited range is
possible with a covered probe.
•
On completion, switch off simulation again in order to continue normal measurement.
