Table of timings

Symbol Description
t0 Stand-by: The burner is waiting for heat demand
t1 Waiting time for an input signal: reaction time, control box remains in waiting status
for t1
t2 Initialization check time: time interval after start main supply
t2l Checks extraneous light during t2: waiting status for t2l, after goes in lock-out
t2p Oil pre-heating time : waiting status for t2p, after goes in lock-out
t3 Pre-purge time: the fan motor is working
t3l Checks extraneous light during pre-purging: Control box goes in lock-out immediately
t3i Spark pre-ignition time
ts Safety time
t4i Total spark ignition time
t4l Reaction time to achieve safety shut-down due to flame failure
t5 2nd stage time: delay time between 1st stage and 2nd stage
t5i Spark post- ignition time
- Minimum time to reset the control box
tr Re-cycles: Max. no. 3 repetitions of complete start-up sequence if there is a flame fail-
ure during operation; the final action at the last attempt following flame failure is a lock-
out
tpp Post-purge time: additional purge time at the end of heat demand can be interrupted
by a new heat demand
* independent by flame control-box
