Flame monitor with Flame detector KLC2002
Carry out the following checks after start-up and after the
burner has been serviced:
• After the start pulse is given, the LERD may only flash
during the pre-ventilation cycle.
• During operating, pull out the sensor and
cover it well: the LED must flash. The control unit
tries to restart and goes into lockout mode on
expiration of the safety interval.
• Restart with covered sensor: LED must only flash. The
control unit must switch to lockout mode when the
safety interval expires.
• Burner start-up with the sensor exposed to external
light, e.g. fluorescent lamp, incandescent bulb (lighter,
daylight or similar are not sufficient!). The LED of the
KLC flame detector lights up continuously for approx.
3 sec., then flashes. The control unit switches to
lockout mode when the safety interval expires.
Important note:
the safety function of fault frequency sup-
pression prevents flame simulation by means of a simple artificial light source.
During normal burner operation, the LED is lit continuously.
