Fault 351 The curve set was changed during operation
760
Check wiring
Especially the activation of terminal 75
___________________________________________________________________
Even if the "flying curve switching” software option 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.

No signal defaults are accepted 24 V possibly defective (terminal 9 and 10)
(Status remains "Burner OFF”) Check fuse F2 (on power supply front panel)

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 being fed in
- terminal 9 and 10 are possibly transposed
Otherwise A7
