3.4.4 Start signal, pressure switch relief
Output X4-03 is controlled depending on parameter
Start/PS valve
Start signal
If parameter
Start/PS valve
is set to
Start signal
, the output is con-
trolled in phase 21 to phase 79.

Pressure switch relief
If an air pressure switch is fitted, continuous venting or direct start is only possible
via pressure switch relief. To do this, a normally open vent valve has to be fitted to
the air pressure switch and parameter
Start/PS valve
must be set to
PS
Reli_Inv
The output is controlled together with the fan motor, except at start
release (phase 21) and direct start (phase 79). The output is not controlled in
phase 21 and 79, the air pressure switch de-energises via the open vent valve and
the signal at input X3-02:1 corresponds to the program sequence.

Application
on in Ph38
Output is controlled in phase 38 and 40
(short pre-ignition).
Dual fuel burners with magnetic coupling
between burner motor and oil pump.
Burners with separate pump or pump
station.
on in Ph22
Output is controlled in phases 22 to 40
(long pre-ignition).
Burners with oil pump coupled directly
to the burner motor.
