1

Power ON

Power is applied across terminals 1 and 2.

(POWER LED lights up)

Flame detection

Relay 2K is turned on by a false flame signal.

(FLAME LED lights up)

2

Start contacts ON

When the start contacts are closed power is applied

across terminals 7 and 2. The start check is carried

out, and relay 1K does not turn on because 

a false flame is detected.

3

Start contacts OFF

Power across terminals 7 and 2 is cut off. The 
FRS100 returns to standby status and waits for 
the next start signal.
If the false flame signal is continuous, the FLAME 
LED is also ON continuously.

Note: It is possible that relay 2K may turn ON when the power is turned on.
