Time is expressed in seconds.
Standby time pending an input signal to control box:
t1
reaction time, the control box remains idle for the time t1.
t1I Presence of extraneous light before the heat request: if
the presence of light during the t1l time, a block follows.
Standby time after a heat request:
t2
the control box remains idle for the t2 time.
t2I Presence of extraneous light during the oil preheating:
if the presence of light lasts the t2l time, a block follows.
t
4l
Maximum preheating time:
t2p
.
if the thermostat K does not make the switch within the
time t2p a block follows, the control box remains still for
the time t2p.
Pre-purging time:
t3
start of the fan motor.
Transformer pre-ignition time:
t3i
ignition of the transformer before the opening of the 1st
stage valve.
t3I Presence of an extraneous light during pre-purging:
Fig. 23
immediate block.
Transformer ignition time:
t4i
total turn on time: ts + t5i + t3i.
t5 Delay time between the 1st and 2nd stage:
2nd stage valve opening time after the opening of the 1st
stage valve.
t5i Transformer post- turn on time:
additional turn on time after ts.
Flame loss in operation:
t4l
maximum oil valve drop reaction time, after three recycle
attempts a block follows.
Post-purging time:
t6
supplementary purging time upon opening of limit ther-
mostat (TL) for heat request.
Presence of an extraneous light during post-purging: if
t6I
the presence of light lasts the t6l time, a block follows.
Long pre-purging time:
t7
pre-purging time more than t3.
Safety time:
ts
if there is no flame at the end of the ts time, a lockout fol-
lows.
