SYSTEM OPERATION

IMPORTANT
The automatic ignition controls S4560P, Q, R,
and T do not have an independant manual reset
function. The application of these types is therefore
restricted to only those applications where resetting
by switching off the heat demand is allowed.
Automatic ignition control for atmospheric appliances
See fig. 3. and 4. for suffix A, B, P and Q and fig 7. for suffix E
When there is a call for heat, a waiting period (T
before built--in or external igniter and gas valve is switched
on.
Ignition spark ignites gas and resulting flame is detected by
the flame rod.
Internal ignition is switched off immediately after flame is
established and --if appropiate-- external ignition is switched
off after elaps of stabilisation time.
If flame is not established within the safety time (T
automatic ignition control locks--out.
If flame is lost during normal run, the automatic ignition control
repeats start sequence (except suffix E).
In case of ignition control with LPG valve connection, gas
pressure switch and TTB switch, the ignition control waits for
gas pressure before normal sequence is started.
If TTB switch becomes active all valves are de--energized.
The TTB switch has to be reset before sequence will start
again.
Automatic ignition control for fan assisted appliances
See fig. 5. and 6. for suffix C, D, R and T
When there is a call for heat, fan is energized if air proven
switch is in the "NO AIR" position.
When sufficient air flow is proven by the air proving switch, a
prepurge period (T ) elapses before built--in or external igniter
P
and gas valve is switched on.
Ignition spark ignites gas and resulting flame is detected by
the flame rod.
Internal ignition is switched off immediately after flame is
established and --if appropiate-- external is switched off after
elaps of stabilisation time.
If flame is not established within the safety time (T
automatic ignition control locks--out.

If air flow is not proven by air proving switch, automatic
ignition control will remain in a waiting mode with fan
energized.
If flame is lost during normal run, the automatic ignition control
repeats start sequence.
WARNING
If fan/air proving switch response time is  1 s, an
orifice in the air flow switch tube must be mounted in
order to avoid cycling.
lock- out reset
The auto ignition control will be reset by either depressing the
internal or the external reset button in the external wiring
(suffix A, B, C, D and E) or by interrupting the power supply
(suffix P, Q, R and T).
If a first reset is not succesful wait at least 15 seconds before
making another reset.
INSTALLATION AND CHECKOUT
IMPORTANT
Installer must be a trained experienced service man.
Disconnect power supply to prevent electrical shock
and/or equipment damage.
Before installing or replacing any control check that
type number is correct for the application. Never use
a type with a larger safety time for which the
appliance is approved.
The appliance manufacturer's instructions should
always be followed when provided. If such instruc-
tions are not provided see fig. 11. ... 19. for typical
systems.
Ensure combustion chamber is free of gas before
start up.
Conduct a thorough check out when installation is
completed.
At the first start the automatic ignition control can be
in lock- -out; reset to free the control.
WARNING
After moving S4560 automatic ignition control from
outdoor to indoor conditions, condensation may occur.
Do not connect condensated automatic ignition control
to mains.
Mounting
The automatic ignition control should be mounted on a flat
surface by means of 4 mounting holes (see fig. 9.).
Mounting position
The automatic ignition control functions position
independently.
To ensure reliable long term operation mount automatic
ignition control at a position in the appliance with a low
ambient temperature and low radiation.
