20/07/05 - 300005180-001-A
Operation
1 Furnace operation equipped with safety box S4565 BF 1161
Operating principle
The ignition and burner surveillance sequences are ensured by the
safety box.
Behaviour in normal conditions
If needed, the boiler thermostat TCH1 closes the contact. The ignition
transformer TA integrated into the safety control box and the ignition
burner valve VBA (supply to the ignition burner) are switched on. Gas
from the ignition burner is ignited by the ignition electrode and within
the time interval ts; a minimum current of 0.9 µA appears on the
ionisation sensor SF and the gas valve regulation flap (supplying the
principal burner) opens. If, moreover, TCH2 is required, the 2nd
stage valve VP2 opens.
Behaviour in abnormal conditions
- If the flame is not detected before the end of the safety time ts, the
safety control box goes into safety lockout and the safety lockout
warning light comes on. To restart the heater, press the reset
button on the safety box.
- If there is a loss of flame in normal operation, the box automatically
repeats the start up sequence.
- If the flame goes out before start-up, the safety control box remains
on standby.
Resetting
The box is reset after going into safety by pressing the reset button.
If the reset button does not work, wait at least 15 seconds before
trying a second time. After activating the reset button, the warning
light goes out and the safety control box restarts after a waiting time
of around 1 minute.
Note 1: The box may be on safety on its first start up: press the reset
button to release it.
Note 2: If the reset button is pressed in normal operation, the gas
valves close and the box starts a new ignition sequence.
