Page 9: Checking The Operation Of The Flame Monitor Control Unit
Checking the operation of the flame monitor control unit 12. Checking the operation of the flame monitor control unit The DKO control unit uses a microprocessor-based programming sequence to produce extremely stable tim- ings independent of fluctuations in the line voltage and ambient temperature. The built-in visual information sys- tem allows continuous progress monitoring and provides information on the causes of a fault shutdown. - Page 10 Checking the operation of the flame monitor control unit Function test A safety inspection must be carried out on the flame monitor on commissioning as well as after a service or lengthy shutdown. Start-up with covered flame detector: The burner must go into fault mode after the safety period. Start-up with flame detector exposed to light: The control device must switch over to fault mode, see IRD function description.
