Function testing the control unit

15. Function testing the control unit

Carry out the following checks after start-up and after the burner has been serviced:

Restarting with a covered flame detector:
the control unit must go into fault mode on expiration of the safety period. 

Burner start-up with flame detector exposed to external light, e.g. fluorescent lamp, lighter, light bulb
(daylight is not enough):
The control device must switch over to fault mode during the pre-aeration period as a consequence of 
the external light.

Normal start-up - if the burner is in operation, darken the flame detector during the post-ignition
period (e.g. unplug and cover flame detector)
TF 834: the ignition must switch on and upon expiration of the safety period the device must switch 
over to fault mode.

Post-aeration after flame cut-off.

Safety and switching functions

If a flame failure occurs during operation, the fuel feed shuts off immediately and the system tries a restart,
with pre-aeration and retarded ignition. If no flame results, the control box indicates a fault after the safety
interval expires. In any case, the control unit is restarted following a mains power failure. The control unit
indicates a fault if an external light source is detected during the pre-aeration cycle after expiration of the
safety cycle.

The control unit may only be plugged in or unplugged if the master switch is in the "OFF" position
or if the 7-pin plug connector is disconnected, because the bottom part of the control unit
carries 230 V.
Incidence of external light on the photoresistor or flame detector must be prevented (e.g.  through
a sight glass or red-hot fireclay lining). Only then is fault-free operation of the system assured.
