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
remains immobile, as does the switch position indicator. The symbol visible on the indicator reading disk indica-
tes 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 com-
mand 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 auxi-
liary 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
signal 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 gene-
rally to be attributed to a premature or abnormal flame signal caused, for example, by self-ignition of a UV tube.
