SPECIFICATIONS S4565PV, QV, RV, TV
General
The S4565PV, QV, RV, TV are multitrial volatile ignition
controls in accordance with EN 298. The S4565RV and TV
are fan assisted versions with or without prepurge, (reset by
means of interrupting the permanent live or by a reset
switch). Non volatile lock-out of S4565PV, QV, and S4565RV,
TV without prepurge are obtained if the status output is
used to store the lock-out status in the comfort boiler control
e.g. with the use of EEPROM. (see Fig. 58.)
The alternative S4565RV, TV versions with prepurge option
do not contain an independent manual reset function, (reset
by means of interrupting the heat demand).

Remark
Optional integrated flame relay available with safe separation
or opto coupler with safe separation according EN 60730.
WARNING
Opto coupler interface needs a debounce
time > 500 ms in order to prevent noise caused by
transients on mains or by status transitions.
Opto coupler status output
• After heat demand during waiting time (T
w
) or prepurge
time (T
p
) the status signal must be logic “0”.
• After the waiting time (T
w
) and without flame the status
signal must be logic “1”.
• After flame detection the status signal must be “50 Hz”.
• If after the safety time (T
s
) there is no flame detection, the
ignition control goes to volatile lock-out. The status signal
is logic “0”.
• If high limit (LM) opens during operation the status signal
becomes logic “0”. The ignition control makes a restart but
the status signal stays logic “0” during the safety time (T
s
).
This is the high limit indication status. The ignition control
goes to volatile lock-out. The comfort boiler control has to
store this status in a semi permanent memory in order to
achieve non volatile lock-out. Line voltage interruptions
may not cause data loss.
