4.2.2 Displaying the Running Time Meter
NOTICE
The sum of the curve set 1 running hours and curve set 2 running hours does not necessarily
give the running hours value, which is displayed in total. The total counter relates to the FMS
running hours. It runs as soon as the unit is connected to a power supply (this also provides
the basis for the fault history).
The single running time meters relate to the burner running hours. These run as soon as the
burner is in operation with the respective curve set (flame signal to the FMS).

4.3.1 What Happens if There is a Fault?
NOTICE
If the processor detects a fault, it runs the outputs in the programmed direction, e.g. air on, fuel
off, re-circulation closed.
The fuel solenoid valves close. The fault signal relay pulls on with a few seconds delay. Auto-
matic restarting may be possible, depending on the nature of the fault.

content:
– total running hours
– running hours on curve set 1

If you use the 4 curve set or 8 curve set option the dis-
play shows the running hours and starts on the addi-
tional curve sets.
