OPERATION
Combustion air blower is turned on and process limits
are controlled by external circuitry (see wiring).
At power on the device perform a self-test 8

displays messages if system failures are detected.
Once the equipment has been successfully tested, the
device waits for manual start-up S
SS
S(stand-by mode), or
starts Prepurge time P
PP
P(autostart mode) depending on
the selected configuration.
A flame detection or simulation during Prepurge time
leads to lockout condition. Ignition device is activated
during Prepurge time for oil burners only (preignition).
A short preignition time is anyway produced (all burner
types) before opening the fuel valve, which remains
open during the programmed safety time I
III .
If a stable flame has been detected the burner is
regularly ignited 2

If the burner does not ignite within the set safety
time, the system locks out U

F, and the system can (depending on
the selected configuration) :
retry the ignition immediately (respark);
restart a complete cycle again (recycle);
wait for reset (lockout).
The burner can be stopped by:
switching off the power supply;
pressing the front panel button, manual shutdown 0

remote communication command (remote halt h

internal timer (if enabled).
After a lockout or shutdown request a postcombustion
time is allowed Y

A point .
...will appear on the display (along with the
associated code) during Postpurge time.
The device can stop the burner after programmed auto
shutoff time (5m to 20h50m) of continuous operation
and restart again, providing that all the equipment and
burner safety tests are successfully performed.
The aux SPDT contact will be activated when the burner
is running and released when in lockout condition
(positive action).
Custom component (diode, resistor…) can be placed
in series to common return of aux relay to meet analog
telemetry supervision request.
Complete remote control through serial communication
line is available for devices equipped with the optional
'TraxBus' interface.
