Via the temperature sensor and flame monitoring system, the electronics monitor gas
heater operation. If there is no stable flame at the ignition burner within 7 seconds,
the electronics indicate a malfunction. The gas supply is interrupted and the red indi-
cator lamps on the ignition box and in the switch cabinet light up.

In the event of a malfunction during the switch-on phase, the starting process can be
repeated up to three times. If the malfunction still occurs after three start-ups, the
cause of the malfunction has to be eliminated before starting again.
When the flame is correct, the screed is heated until the temperature sensors in the
individual screeds interrupt the heating process. During the heating phase, the yellow
indicator lamps (12, 13, 14, 15) in the switch cabinet and the yellow indicator lamps
on the ignition boxes (35) indicate a correct flame at the burners.
In the event of a malfunction, the red indicator lamps (16, 17, 18, 19) in the switch
cabinet and the red indicator lamps on the ignition boxes (34) indicate that the flame
at the burners is not correct.
m
The indicator lamps are important for trouble-free operation of the ignition system.
Therefore, defective bulbs should be immediately replaced!

A
Use the high temperature to preheat the
screed and the extendable parts/exten-
sion parts before starting work; this pre-
vents bitumen materials from sticking to
the tamper knives and to the bottom
plates on the first meters laid.
Usually, the switches can be toggled to the low temperature after a short time.
