Operating modes
9.1.
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 operat-
ing mode:
a genset operation is immediately ended
previously displayed error messages, except the fault messages 9 and 10, are deleted 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 ac-
tive, unlocking is not possible; the
AUTOMATIC SYSTEM LOCKED
message remains.
9.2.
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. If the generator
voltage lies within the nominal ranges with its voltage and frequency values, the generator can be
switched on with the G
EN
-O
N
(
I
) key or off again with the G
EN
-O
FF
(
O
) key. The actuation of the O
N
key remains ineffective if the generator voltage does not lie within the specified limits.
All switching processes are only carried out manually and not automatically. Even a remote start order
does not lead to the automatic switch-on of the generator. In order to switch off the genset, the O
FF
or
(in the event of the remote start command being missing) A
UTOMATIC
operating mode must be select-
ed.
9.3.
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 AUXILIARY DRIVES
signal is present. If no auxiliary drives are required (for start release), ter-
minal 8 from X2,
START RELEASE
should be switched with L-. If the genset has not started at the end of
the starting program, the
FAILED START
/
MOTOR FAULT
alarm is issued and the automatic system inhibit-
ed. After the start-up of the genset, the generator is switched on as soon as the nominal generator
voltage and frequency are reached.
After removal of the start command, the generator is switched off immediately. In order to prevent heat
build-up, if it was loaded the genset continues to run without load for the run-on time set and then is
shut down.
In addition to the remote start, the genset can also be started via the Sprinkler command (see further
in this document).
9.4.
Test operating mode
After button selection to the T
EST
position, the start program is triggered. The
START CONTROL
indica-
tion 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-.
If the generator voltage lies within the nominal values parameterised with its voltage and frequency
values, the generator can be switched on with the G
EN
-O
N
(
I
) key or off with the G
EN
-O
FF
(
O
) key.
If a remote start command occurs during test operation, the system switches to generator operation.
Then, it is not possible to manually switch off the generator circuit breaker. A manual operation of the
switch is only possible after the remote start command has been withdrawn.
In order to switch off the genset, the O
FF
or (if the remote start command is not present) A
UTOMATIC
operating mode must be selected.
