IONIZATION CONTROL
◄
Safety connections are open, program won’t run.
Flame distinction during operation, error mode.
▲
Air damper fully open.
P
Air pressure is not enough, error mode.
■
Problem in flame detection circuit, error mode.
▼
Gas flow.
1
Flame signal not formed at the end of safety time, error mode.
2
Flame signal not formed at the end of 2nd safety time, error mode.
Normal operating mode.
ERROR CODES (LFL 1.322)
22
1.
The red light on the control unit is on when burner is in error mode. Take off the plastic cover by
unscrewing the 3 screws. Determine the below defined error types from the indicator on LFL
1.322.
2.
Press once on the indicator placed on the control unit. This will reset the control unit. Below are
the signs and definitions of the error types stated on LFL 1.322.
3.
The burner starts only after resetted. If the control unit error code related problem is not fixed, the
burner will switch to error mode again.
Microampermeter is connected as seen above in order to measure the ionization current. The
connection to modulating burner’s control unit is shown in the Figure above. The microampermeter
must have enough resolution to indicate a minimum current value of 15 µA.
