Ignition process

When the screed heating switch is switched on:

•

The control unit opens solenoid valves to supply gas to the

burners.

•

The control unit activates ignition units and unless perma-

nent fire is achieved within 7 seconds, the electronic system

indicates a fault.

•

If everything is OK, gas is automatically ignited by spark

plugs. Whether or not the flame is burning is evaluated by

the ignition unit through the spark plugs. After reaching

the temperature of 120°C on the screed temperature sen-

sor, the heating is automatically interrupted. After reducing

the screed temperature, heating is automatically activated

D451627

by the control unit.

•

If the flame cannot be ignited for any reason, a red Led indi-

cator is turned on on the ignition unit for the relevant sec-

tion, and an error message is displayed on the display.

Error message on the display:

F75 - Left screed extension

F76 - Main screed

F77 - Right screed extension

LED indicators on the ignition unit:

•

red LED indicator (1) - indicates a fault of the ignition system

for the given section

•

green LED indicator (2) - the ignition system is active

D451628

•

orange LED indicator (3) - is illuminated = it is burning, is not

illuminated = is not burning.
