3 System Operation
H1
Fault 600
The control unit has locked up
- call-up running text and follow instructions there
Check wiring and external signal transmitters e.g.
- safety interlock chain boiler
- safety interlock chain gas
- air pressure monitor
- safety interlock chain oil (special function)
- fuel selection (special function)
- external high firing rate acknowledgement
- external ignition position acknowledgement
Check motor limit stops
otherwise
Extend program monitoring time
see parameterisation, parameter 777 (only with level 1 access)

H2
Fault 001, 003,
005...010,
604
The flame signal does not appear during the ignition process (terminal 8)
(or with separate ignition flame monitor terminal 7)
Check wiring
Check ignition transformer and, where necessary, pilot burner
Check flame sensor
The exact time after ignition is 3 sec., after H004 appears.
H3
Fault 606
In the FMS the parameters may be set, that the gas > min monitor is also monitored in oil op-
eration.
Check gas pressure monitor
Alter configuration (P 761)
H4
Fault 607
The ignition position acknowledgement signal drops during the ignition sequence
(terminal 74)
TIP:
The ignition position acknowledgement signal must be present up to the end of the ignition
sequence (to the end of the 2
nd
safety period).
H5
Fault 605
In the FMS the parameters may be set, that instead of the "Re-circulation On” signal (terminal
6), an oil pressure > min signal is monitored.
Check oil pressure monitor
Alter configuration (P 762)
H6
Fault 711...745
The monitoring processor checks the control unit cycle for plausibility. It has detected a fault
in the cycle.
H8
Fault 734
For one of the processors the pre-ventilation is still running while the other one already termi-
nated the pre-ventilation.
