Trouble-Shooting
When the instructions in the manual have been followed correctly, the system must now
function. Should this not be the case, the Silometer FMX 570 transmitter provides a
number of aids for setting up and operating the module correctly. This Chapter contains
the following:
•
Trouble-shooting tables, with error messages, meaning and response
•
Description of simulation operating mode for service and commissioning
purposes
•
Instructions for commissioning replacement electronic inserts, probes and
transmitters.
•

Trouble-shooting tables
Fault condition
When the FMX 570 transmitter recognizes a fault condition:
•
the red fault LED lights and the alarm relay trips.
•
the output current (with the exception of operating mode 2) reverts to the
status selected in field V0H7, i.e. to -10%, +110% of the selected measuring
range or last measured value (hold) - see Chapter 6.
A diagnostic message is given in Field V9H0:
•
If the cause of the fault has been rectified, the last diagnostic message is
retained in V9H1.
•
This message can be cleared by pressing the »E« key.
If the power fails, all relays de-energise.
Warnings
When the FMX 570 transmitter has detected a warning:
•
the red fault LED flashes but the Silometer continues to measure
•
the alarm relay remains energised
•
the appropriate message is to be found in V9H0.
The error messages are listed in Table 7.1 in the order of their priority. If one fault is on
display and a fault of higher priority occurs, the latter will appear at V9H0. The preceding
message can be called by pressing the "plus" key.
Table 7.2, trouble-shooting, indicates possible configuration errors for the Silometer
FMX 570.
