If no malfunction is detected during the waiting time t
W
, the 
ignition time t
Z
 then starts to elapse. Voltage is sup- plied to 
the gas valve V1 and the ignition transformer and the 
burner is ignited. The duration of the ignition time is either 
2, 3 or 6 seconds, see page 35 (Techni- cal data).
 
 
Once the start-up signal 
 
has been applied, the wait- ing 
time t
W
 starts to elapse. During this time, a self-test is 
conducted to detect errors in internal and external circuit 
components. If no malfunction is detected, the burner will 
start up.
