11.1.
Monitoring on
This green display (after the genset start-up) signals the release of the operating-dependent delayed alarms. As
soon as the motor has started up, this display flashes until the monitoring is enabled. The display goes out at
the beginning of the shut-down process.
11.2.
Automatic system locked
This red display illuminates if an alarm to be switched off has elapsed or the external quick stop was actuated.
In order to unlock the system, the Off operating mode must be selected. If the signal cannot be cleared even in
Off, the external quick stop is still active.
11.3.
Start control
The message will be activated as soon as a start request is present in automatic mode or if manual or test mode
has been selected. The display flashes as long as there is no start release. The display goes out as soon as the
genset exceeds the ignition speed during start-up (recognised from the D+ signal of the generator or from the
revolution transmitter signal). Switching on the starter is then inhibited, even if attempted manually. The starting
generator voltage interrupts the start but does not cause the
START CONTROL
indicator to extinguish.
