General displays
The two upper rows of the LEDs provide important information on the operating processes and error mes-
sages. 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 released. 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 er-
ror). 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 display goes out as
soon as the genset exceeds the ignition speed during start-up (recognised from the D+ signal of the genera-
tor and also from the speed sensor signal according to the parameterisation). Switching on the starter is then
inhibited, even if attempted manually.
7.4.
Failed start / Motor malfunctions
This alarm is controlled by three criteria. That's why this message has expired needs to be interpreted. 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 inhib-
ited.
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.

Operating modes
8.1.
Off operating mode
The O
FF
position is automatically selected (reset function) during the application of battery voltage in order to
prevent the triggering of an unintentional start-up. When switching to O
FF
from another operating mode:
a genset operation is immediately ended.
previously displayed error messages, except the fault messages 9 and 10, are cleared as long as their
alarm contact is still active.
the automatic system is unlocked. However, if the Q
UICK
S
TOP
(E
MERGENCY
S
TOP
)
input is still active, un-
locking is not possible; the
AUTOMATIC SYSTEM LOCKED
message remains.
Manual operating mode
The
START CONTROL
indication flashes as long as there is no start release and the
SWITCH ON AUXILIARY
DRIVES
signal is present. If no auxiliary drives are required (for start release), terminal 8 from X2,
START
RELEASE
should be switched with L-. The motor can be started using the S
TART
key.
In order to switch off the genset, the O
FF
or (in the event of the external start command being missing)
A
UTOMATIC
operating mode must be selected.
8.2.
Auto operating mode
After the external start command is present the genset will be started after the parameterised delay time has
elapsed. The
START CONTROL
indication flashes as long as there is no start release and the
SWITCH ON
