Sprinkler operation
The following functions are intended for the operation of an electrical sprinkler pump:
Switching of all shutdown alarms (overspeed alarm remains switched off for electronic speed sen-
sor, demand VDS 2100-22) to warning
Optionally, the inhibition of the generator switch-off function for
GENERATOR OVERCURRENT
, for ex-
ample
Start program to 6 (parameterisable) start attempts
Upon sprinkler request being withdrawn: Cessation of the sprinkler operation after the
SPRINKLER
IDLE TIME
, or only manual switching off
for the duration of the acceleration time of the sprinkler pump: Switching off of the normal consum-
ers or no interruption.
The supply of the sprinkler pumps is usually taken care of directly by the generator and thus prior to
the switch to the emergency power consumers. If a sprinkler request is arises, the genset starts. In the
event of an additional request from the remote start command, the consumers can be switched off for
a parameterisable period of time in order for enough energy to be available to allow the sprinkler pump
to start up. Furthermore, it is possible to parameterise that the consumer switches remain switched on
or switch off in the event of an overload on the side of the consumers.
Sprinkler operation is automatically cancelled after the sprinkler requirement is removed after an en-
tered idle time or can only be ended manually (demand VDS 2100-22).
If the automatic system is pa-
rameterised for manual shutdown, the LED of the O
FF
operating mode flashes as soon as the sprinkler
input is free. Stopping can then be carried out via the O
FF
operating mode (or always via Emergency
Stop).

Error messages / Programmable operation indicators
Any of the 10 LEDs can either display an error message or be parameterised as an operation indica-
tors.
10.1.
Use as an operational indicator
These displays are independent of the selected operating mode. Thus, they can be used as displays
of operational conditions via contact inputs as normal signal lamps. The parameterisation is described
in the service instructions.
10.2.
Use as an error message
The arrival of an error message is displayed by the LED flashing. At the same time, the acoustic signal
(for the entered duration) is controlled. The acoustic signal is switched off with a pulse from the A
LARM
O
FF
key (or automatically after the entered time). However, the LED continues to flash. If the value 0
sec. is entered for the duration of the horn switch-on, no automatic switch-off is carried out: The horn
remains switched on until manually deleted.
Due to a second button actuation of A
LARM
O
FF
, the message switches from flashing to continuously il-
luminated. Due to the necessary second acknowledgement, e.g. the switching off of the acoustic sig-
nal generator after an automatic switch-off, it can be distinguished which error message has newly oc-
curred.
The display is cleared after the error is eliminated after renewed actuation of the A
LARM
O
FF
key.
With messages that lead to the switching-off of the genset, further operation is inhibited and this is in-
dicated by
AUTOMATIC SYSTEM LOCKED
. In order to unlock, the O
FF
operating mode (any actuated ex-
ternal Emergency OFF buttons must also be unlocked) must be
selected.
If the generator is switched off due to a warning alarm in automatic operation, the engine is stopped after the idle
time and the automatic system is locked.
The parameterisation is described in the service instructions.
10.3.
Alarms 9 and 10
Both these alarms can be delayed from 0 to 240 sec. by the signal transmission, i.e. for the alarm con-
tact to issue an error, the signal must be pending for a parametrised time. Furthermore, both these
alarms are also effective in the Off operating mode (Off), but without switching on the horn. Thus, crite-
ria (e.g. tank overfilling, leakage warning) that always have to be reported can be monitored.
