Page 13: Final Checks
FINAL CHECKS • Obscure the photocell and switch on the control devic- es: the burner should start and then lock-out about 5 s after opening of the low fire nozzle operation valve. • Illuminate the photocell and switch on the control cir- cuit: the burner should go into lock-out . -
Page 14: Burner Operation
BURNER OPERATION BURNER STARTING (A) Operating control closes. The motor starts and the ignition transformer is con- nected. The pump 3) sucks the fuel from the tank through the piping 1) and the filter 2) and pumps it under pressure to delivery. -
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 6), 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) LAL2... Sub-base Min value for a good signal: 8 μA. 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 A c.c., connected to the scanner, as in the dia- gram. -
