S4565C,D,R,T - Honeywell 1000 Series Instruction Sheet

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

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.

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 (T
S4565 ignition control locks out.
If the flame is lost during normal run, the S4565 ignition
control repeats start sequence.
