Page 14: Final Checks
FINAL CHECKS • Obscure the photocell and switch on the control devices: the burner should start and then lock-out about 5 s after starting. • Illuminate the photocell and switch on the control devices: burner should go into lock-out. • Obscure the photocell while the burner is operating: flame should go out and burner lock out within 1 s. -
Page 15: Procedure To Refer Burner Operating Condition In High Altitude Plants
PROCEDURE TO REFER BURNER OPERATING CONDITION IN HIGH ALTITUDE PLANTS Find the corrected burner capacity for the plant’s altitude in chart 1 and the corrected pressure in chart 2. Check in the firing rate graph of the burner (page 5), if the working point defined by the values above is within the range limits. If not, higher burner size is needed. -
Page 16: Flame Signal Measurements
FLAME SIGNAL MEASUREMENT (A) Min value for a good signal: 8 μA. LAL2... Sub-base If the value is lower, it can be due to: • Worn photocell; • Low current; • Bad set up of the burner. In order to measure the current, use a microammeter of 100 μA c.c., connected to the scanner, as in the dia- gram. -
