Warnings
1.
The connection of the unit must be carried out carefully, as a wrong connection could lead to
the destruction of the unit. The connection regulations must be observed.
2.
The PE(N) must be connected to the point marked with the earthing symbol.
3.
The installation and commissioning must only be carried out by sufficiently q ualified person-
nel.
4.
Applicable regulations, especially those of the VDE must be observed.
5.
The information in the service instructions must be complied with prior to commissioning.
6.
The parameterisation of the unit must be carried out in such a way that end angerment of
persons and property is excluded.
7.
If the battery has to be disconnected, the charging unit must be switched off.
8.
The battery negative potential must be earthed at the input terminal on the switchboard. The
minimum cross-section is 10 mm
2
.
9.
The supply voltage (12 or 24 V DC) is selected using a switch located on the circuit board
under the hood.
10. If the supply voltage of the automatic system was switched off, it must only be switched on
again after approx. 20 seconds.
11. All the coils must be provided with a freewheeling diode (for DC voltage) or with a suppressor
circuit matched to the inductance of the coil. This also applies for all relays and inductances
that are used differently in the switchgear or are externally controlled.

General description
The
KEA 291 NSTR
automatic system is a further development of the KEA 091 NSTR. It is used in
emergency power systems. Both Diesel and gas motors can be controlled. All controls, displays and
the mimic diagram are arranged in a clear manner. Menu-driven guidance has been omitted in order
to keep the handling simple and the system user-friendly.
The automatic system includes all functions for automatic emergency power operation and manual
operation. All functions allocated to the genset for sprinkler operation are included (according to
VDS 2100-22).
The mains voltage is monitored across 3-phases and the generator voltage across 2-phases. The
voltages and frequencies are monitored for levels that are either too high or too low. In addition, the
rotating field of the mains voltage can be monitored. The device can also be used for single -phase
AC without alterations.
Ten displays can be selected as alarms or operational indicators. Provision has been made for re-
mote acknowledgement of alarms.
The speed is measured via a pick-up or the generator frequency and can be monitored for over-
speed.
The battery voltage monitor, a start counter and an operating hours counter are integrated.
Ten freely selectable alarm messages and the monitoring of the mains and generat or switches are
provided for the monitoring of the peripherals and the genset.
There are 10 relay outputs available for controlling the motor and the peripherals, switching power
35 V DC, 1 A. The function of the 7 relays and all of the parameters can be s et via a USB interface.
The P
ARA
W
IN
software is required for this.
All relevant values and signals can be read out via an add-on module.
The device is delivered with standard parameterisation and labelling.
