ALARM
In lockout position (Phase 00) a mains voltage signal is emitted at alarm out-
put X3-01:2.
Additionally, it is also possible to signal prevention. To do this parameter
Alarm-
StartPrev
is set to activated [ch. 6.8.2]. The time, before a start prevention trig-
gers an alarm is set in parameter
AlarmDelay
Parameter
Alarm act/deact
is used to deactivate the alarm signal [ch. 9.1.1].
The deactivation only affects the alarm output, lockout or start prevention are not
reset. Reset or burner start are reset automatically by the deactivation and the
alarm output is ready of use again.

The fan motor is connected to output X3-01:1 via contactor or star delta switching.
Depending on parameter
ContinuousPurge
the output is controlled from
Phase 22 or continuously [ch. 6.8.7].
If an air pressure switch is fitted, continuous running fan is only possible via pres-
sure switch relief. To do this, a vent valve has to be fitted and connected to out-
put X4-03.

Either the magnetic coupling, a separate oil pump or the anti syphon valve are con-
nected to output X6-02.
The type of oil pump coupling is set in parameter
OilPumpCoupling
, see
Magnetic coupling / separate oil pump
On dual fuel burners with magnetic coupling or on burners with separate oil pump,
parameter
OilPumpCoupling
is set to
Magnetcoupl
. The switch-on point
of the ignition should be set to short pre-ignition (
on in Ph38
). In light oil opera-
tion, the output is controlled from the start of pre-ignition (phase 38) to operating
setting 2 (phase 62). In heavy oil operation, the output is controlled in phase 36, to
ensure oil pressure is available for the subsequent nozzle circulation.
Direct coupling
On oil burners with the oil pump directly coupled to the burner motor, the anti sy-
phon valve is connected to output X6-02. Parameter
OilPumpCoupling
must
be set to
Directcoupl
, this means that long ignition is activated automatically.
The output is controlled together with the fan from phase 22 and remains activated
for a further 15 seconds after the fan has switched off.
