IGNITION CONTROLS FOR COMBINED VALVE AND IGNITION SYSTEM
EN1R--9161 0006R10--NE
”Old”-- style ”New”-- style
APPLICATION
The Combined Valve and Ignition system (CVI) has specially
been developed for application in gas fired appliances with
either intermittent pilot or direct burner ignition.
For this system, the VK41../VK81.. series gas controls have
been designed to have the S4565/S4575/S4585 series
ignition controls attached directly onto the valve.
The combined system then provides programmed safe light
up, flame supervision and regulation of gas flow to the main
burner and/or pilot burner of the appliance.
DESCRIPTION
The S4565/S4575 ignition controls provide automatic ignition
for direct gas burner applications and for intermittent pilot gas
burner applications with safety timer.
The S4565/S4575 ignition controls are not intended for direct
exposure to flame envelope.
The S4585 ignition controls provide automatic ignition for
intermittent pilot gas burner applications without safety timer.
The S4565/S4575/S4585 ignition controls are designed to
meet the european standards:
EN 298: Automatic gas burner control systems.
EN 60730--1: Automatic electrical controls for house hold
and similar use.
The S4565/S4575/S4585 ignition controls can be used in
appliances according European standard for household
electrical requirements EN 60335 series.
The S4565/S4575 ignition controls are approved on the North
American standard ANS Z21.20 Automatic Ignition Systems.
NOTE: S4565SD is not an ignition control but an ignition
circuit and rectifier only

SYSTEM OPERATION
General
Lock- out reset
The S4565 ignition control can be reset by either depressing
the internal/external reset button (suffix A and B) or by
interrupting the permanent life (suffix P and Q).
NOTE 1.: If during normal use the reset button is pressed,
the gas valves drop out and the S4565 ignition
control starts a new sequence after releasing the
reset button.
NOTE 2.: If permanent alarm output:
neon indicator with integral resistor >150 kτ
Εmax 1 mA)
NOTE 3.: If an return high limit thermostat is used, the high
limit switch in the application needs a longer return
time than the trial for ignition time of the control.
This in order to provide non volatile lock out.
Suffix A, B, P and Q (see fig. 4.)
When there is a call for heat a self check period (Tc)plus
waiting period (Tw) elapse before built--in igniter and gas valve
are switched on.
The ignition spark ignites gas and resulting flame is detected
by the flame rod.
Ignition is switched off after extended ignition time and flame
establishment.
If flame is not established within the safety time (Ts), the
S4565 ignition control locks out.
If the flame is lost during normal run, the S4565 ignition
control repeats start sequence.

SYSTEM OPERATION
General
The S4565AD, BD, CD, DD, PD, QD, RD, TD ignition control
can provide both closed--loop sparking and sparking to
ground.
If the S4565AD, BD, CD, DD, PD, QD, RD, TD will be used in
sparking to ground applications, the upper spark tab has to be
grounded.
Lock- out reset
The S4565 can be is reset by either depressing the
internal/external reset button (suffix AD, BD, CD and DD) or
by interrupting the permanent life (suffix PD, QD, RD and TD).
NOTE 6.: When first starting, the inition control can be in the
lock--out condition; reset the ignition control.
After a reset an extended waiting time will occur.
NOTE 7.: If during normal use the reset button is pressed,
the gas valves close and the S4565 ignition
control starts a new sequence after releasing the
reset button.
NOTE 8.: If permanent alarm output:
neon indicator with integral resistor >150 kτ
Εmax 1 mA)
Suffix AD and PD (see fig. 18.)
When there is a call for heat a self check period (Tc)plus
waiting period (Tw) elapses before the built--in igniter and gas
valve are switched on.
The ignition spark ignites gas and resulting flame is detected
by the flame rod.
After flame establishment a predetermined, extended ignition
time can be included.
If flame is not established within the safety time (Ts), the
S4565 ignition control locks out.
If the flame is lost during normal run, the S4565 ignition
control repeats start sequence.
Suffix BD and QD (see fig. 19.)
As AD and PD except flame relay contact or opto is closed
after flame detection.
Suffix CD and RD (see fig. 20.)
When there is a call for heat the fan starts running through the
no air position of the air proving switch after a self check
period (Tc) plus waiting period (Tw). When sufficient air flow is
proven by the air proving switch, the built--in igniter and gas
valve are switched on.
The ignition spark ignites gas and resulting flame is detected
by the flame rod.
After flame establishment a predetermined, extended ignition
time can be included.
If flame is not established within the safety time (Ts), the
S4565 ignition control locks out.
If the flame is lost during normal run, the S4565 ignition
control repeats start sequence.
If no air is proven by the air proving switch within the safety
time (Ts), the ignition control locks out.
Suffix DD and TD (see fig. 21.)
As CD and RD except flame relay contact or opto is closed
after flame detection.
Gas/air application
For gas/air application without dynamic aircheck, the
S4565AD, BD, PD or QD can be used.
In this application the fan is connected between pin 4 and 5
and will start when a call for heat is present. The waiting
period now acts as a prepurge time.
When the call for heat disappears or when the ignition control
goes in lock--out, the fan will be switched off.

SYSTEM OPERATION
General
The S4565AD, BD, CD, DD, PD, QD, RD, TD ignition control
can provide both closed--loop sparking and sparking to
ground.
The S4565SD ignition circuit and rectifier provides
closed--loop sparking.
Lock- out reset
The S4565 can be is reset by either depressing the
internal/external reset button (suffix AD, BD, CD and DD) or
by interrupting the permanent life (suffix PD, QD, RD and TD).
NOTE 9.: If during normal use the reset button is pressed,
the gas valves close and the S4565 starts a new
sequence after releasing the reset button.
Suffix AD and PD (see fig. 30.)
When there is a call for heat a self check period (Tc)plus
waiting period (Tw) elapse before the built--in igniter and gas
valve are switched on.
The ignition spark ignites gas and resulting flame is detected
by the flame rod.
After flame establishment a predetermined, extended ignition
time can be included.
If flame is not established within the safety time (Ts), the
S4565 ignition control locks out.
If the flame is lost during normal run, the S4565 ignition
control repeats start sequence.
Suffix BD and QD (see fig. 31.)
As AD and PD except flame relay contact or opto is activated
after flame detection.
NOTE 10.: The hour counter is energized when the valve is
energized. It can be used as an output signal.
Suffix CD and RD (see fig. 32.)
When there is a call for heat, self check period (Tc)plus
waiting period (Tw) elapse when the air proving switch is in the
no air position.
After Tc+T
wthe fan starts running.
When sufficient air flow is proven by the air proving switch, the
built--in igniter and gas valve are switched on.
The ignition spark ignites gas and resulting flame is detected
by the flame rod.
After flame establishment a predetermined, extended ignition
time can be included.
If flame is not established within the safety time (Ts), the
S4565 ignition control locks out.
If the flame is lost during normal run, the S4565 ignition
control repeats start sequence.

17 EN1R--9161 0006R10--NE
If no air is proven by the air proving switch, the ignition control
stays waiting (optional lock out on no air can be included).
Suffix DD and TD (see fig. 33.)
As CD and RD except flame relay contact or opto is activated
after flame detection.
Suffix SD (see fig. 27.)
If line voltage is applied between pin 5 (line valves) and
pin 9 (N), the gas valve is switched on.
If the line voltage is applied between pin 4 (line ignition) and
pin 9 (N) the build in igniter is switched on.
The igniter circuit is fed during the negative half wave of the
mains.
Pin 8 is present but not intended for use. It is connected with a
resistor (100 τ)topin5.
Ignition circuit must be on shorter than 10 s in an application
with single ignition trial.
Gas/air application
For gas/air application without dynamic aircheck, the
S4565AD, BD, PD or QD can be used.
In this application the fan is connected between pin 4 and 5
and will start when a call for heat is present. The waiting
period now acts as a prepurge time.
When the call for heat disappears or when the ignition control
goes in lock--out, the fan will be switched off.
