the following:
•
Trouble-shooting tables, with error messages, meaning and response

7.1 Trouble-shooting tables
Alarms If the Gammapilot FTG 671 transmitter recognizes a fault condition:
•
the red fault LED lights and the alarm relay trips
•
the limit value relays assume fail-safe mode as specified in fields V1H3 and
V1H8 - see Chapter 5, p 35.
•
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 Gammapilot FTG 671 transmitter has detected a condition which requires a
warning:
•
the red fault LED flashes but the Gammapilot functions as normal
•
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.
Table 6.2, trouble-shooting, indicates possible configuration errors for the Gammapilot.
