If gas engine selected:
IGNITION DELAY
With gas engines often a purging operation is desired before starting. With the engaging of
the starter the ignition delay is started. If the ‘min ignition speed’ is reached after expiry of
this time, the configurable relay output ‘ignition’ is set.
GAS VALVE DELAY
By setting the ignition relay the gas valve delay is started. After the expiry of the set time as
long as the number of revolutions is higher than the minimum ignition speed, the gas valve is
set. When the necessary engine shutdown process, gas valve is de-energised.
MIN IGNITION SPEED
After expiry of the ignition delay the number of revolutions set must be reached, so that the
configurable relay output ‘ignition’ will be set.
