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 im-
mediately. At the same time, the
programmer remains 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 se-
quence 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 mal-
function.
▼
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.
Lock-out stop, due to lack
1
of flame signal at the end of
the first safety time.
Lock-out stop, because no
2
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 generally to be attributed to a
premature or abnormal flame signal
caused, for example, by self-ignition
of a UV tube.
