General displays
The two upper rows of the LEDs provide important information on the operating processes and error
messages. The displays described below are intended as standard.
7.1.
Monitoring on
Using this green LED (after the genset start-up), the release of the operating-dependent delayed
alarms is signalled. As soon as the motor has started up, this LED flashes until the monitoring is re-
leased. The display goes out at the beginning of the shut-down process.
7.2.
Automatic system locked
The display is switched on by a signal on the Q
UICK
S
TOP INPUT
(E
MERGENCY
S
TOP
), or together with
such alarms that lead to the shut-down of the genset. This LED indicates that the automatic system
is locked for further start attempts and thus genset operation is inhibited.
The automatic system is unlocked by selecting the O
FF
operating mode (after eliminating the cause
of the error). To do so, any actuated external emergency stop buttons must also be unlocked.
7.3.
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 dis-
play goes out as soon as the genset exceeds the ignition speed during start -up (recognised through
the D+ signal of the generator, through the speed sensor signal or through the generator voltage, in
accordance with the parameterisation). 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.
7.4.
Failed start / Motor malfunctions
This alarm is controlled by three criteria. That's why this message has expired needs to be inter-
preted. The message is controlled if
the genset has not started at the end of the starting program. This message,
FAILED START
, is
displayed with a continuous light (without flashing). The automatic system is inhibited.
the automatic system is already running and is brought to a standstill without a stop command.
This message,
SPEED MEASUREMENT FAILED
, is indicated with a flashing light and the automatic
system is inhibited.
the genset continues to run after the stop time has expired. This message, M
OTOR DOES NOT
SHUT DOWN
flashes, the automatic system is not locked.
7.5.
Mimic diagram / Voltage monitor
The mimic diagram displays the mains infeed, the generator, the mains and generator circuit
breakers and the busbar. Green LEDs below the mains or generator symbol indicate if the respec-
tive voltage is within the limits. These LEDs flash as soon as the voltages are within their limits
again, but the release time has not yet expired.
The positions of the mains or generator switch are displayed by green LEDs below the O
FF
keys
(

N THE EVENT OF THE MAINS BREAKER OR GENERATOR BREAKER TRIPPING
(if parameterised), the cor-
responding LED flashes in quick succession after a longer off period.
