Control program in the event of stopping, indicating position of stop
As a rule, in the event of any kind of stop, the fuel flow is cut off immediately. At the same time, the programmer re-
mains immobile, as does the switch position indicator. The symbol visible on the indicator reading disk indicates the
type of fault.
No start-up, because of failure in closing of a contact or lock-out stop during or at the end of the command
sequence because of external lights (for example: flames not extinguished, loss at the level of the fuel valve,
defects in the flame control circuit, etc.)
Start-up sequence stops, because the OPEN signal was not sent to terminal 8 by limit switch contact "a".
Terminals 6, 7 and 15 remain powered until the defect is eliminated.
P Lock-out stop, because of lack of air pressure signal.
Any lack of pressure from this moment onwards will cause a lock-out stop!
Lock-out stop because of flame detection circuit malfunction.
Start-up sequence stops, because the position signal for low flame was not sent to terminal 8 by auxiliary
switch "m". Terminals 6, 7 and 15 remain powered until the fault is eliminated.
1 Lock-out stop, due to lack of flame signal at the end of the first safety time.
2 Lock-out stop, because no flame signal was received at the end of the second safety time (main flame si-
gnal with pilot burners at intermittent operation).
Lock-out stop, due to lack of flame signal during burner operation.
If a lock-out stop occurs at any moment between the start and pre-ignition without a symbol, the cause is generally
to be attributed to a premature or abnormal flame signal caused, for example, by self-ignition of a UV tube.
