3 System Operation
G3
Fault 351, 760
The curve set was changed during operation
Check wiring
Especially the activation of terminal 75
TIP:
Even if the software option "flying curve switching” is activated on the FMS, allowing the curve
set to be changed during operation, it must be remembered that in "EI” mode (Setting) a flying
change is not permitted.
G 6 No signal defaults are accepted (State remains "Burner OFF”)
24 V possibly defective (terminal 9 and 10)
Check fuse F2 (on power supply front panel)
G7
Fault 903
The optical couplers of the digital inputs are cyclically tested to see that they are functioning.
This is done by briefly withdrawing the voltage from terminal 9 (+24 V supply). A check is then
conducted to see whether the signals on the digital inputs also go to 0V.
A voltage remains on at least one of the digital inputs during the self-test.
Check wiring
- terminal 9 might not have been used to supply the inputs.
Disconnect terminal 9
and
Re-measure voltage level on all inputs
- an external voltage is possibly fed in
- terminal 9 and 10 are possibly transposed
Otherwise A7
G8
Fault 108
The digital input signals for main and monitoring processor are compared
Change processor card
