Gas Start sequence
The starter is engaged ("Turning" is displayed). Following the expiration of the
firing delay time and if the engine is rotating with at least the configured "min‐
imum speed for ignition", the ignition is switched on ("Ignition" is displayed).
Following the expiration of the gas valve delay, the gas valve is then enabled
("Start" is displayed). If the configured firing speed is exceeded, the starter is
disengaged. The gas valve and the ignition remain enabled via the firing
speed. "Ramp to rated" is displayed until the engine monitoring delay timer
expires and the start sequence has finished.
If the configured "minimum speed for ignition" is not reached, a start pause is
initiated ("Start - Pause" is displayed) before the next start attempt.
Stop sequence
After opening the GCB, the coasting time starts and the engine runs without
load ("Cool down" is displayed). On termination of the coasting time, the gas
valve is closed or de-energized, and the engine is stopped ("Stop engine" is
displayed).
If the engine cannot be stopped, the alarm message "Eng. stop malfunct." is
displayed. If no speed is detected anymore, the ignition remains active for
5 seconds so that the remaining gas is able to combust.

CAUTION
It is imperative to connect an emergency stop circuit to discrete input DI 1 to
be able to perform an emergency stop by disabling the ignition in case the
gas valve fails to close.
External The start/stop sequence must be done externally.
Off The start/stop sequence is completely disabled.
The delayed engine monitoring is dependent from LogicsManager firing
speed
The GCB release is activated by LogicsManager start request in AUTO

The controllers are deactivated in operating mode STOP.
