The unit is a control and protection panel
designed to monitor the 3-phase mains voltages, send remote
start command to the generating set and make changeover of both generator and mains contactors. The genset is
supposed to be controlled by a Remote Start type control unit.
It shows the measured values on its display. The
unit is designed to provide user friendliness for both the installer and the user. Programming is usually
unnecessary, as the factory settings have been carefully selected to fit most applications. However
programmable parameters allow the complete control over the load transfer. Programmed parameters are
stored in a Non Volatile Memory and thus all information is retained even in the event of complete loss of
power.
Measured parameters are:
Mains voltage phase L1 to neutral
Mains voltage phase L2 to neutral
Mains voltage phase L3 to neutral
Mains voltage phase L1-L2
Mains voltage phase L2-L3
Mains voltage phase L3-L1
Mains frequency
Battery voltage
Gen voltage phase L1 to neutral
Gen voltage phase L2 to neutral
Gen voltage phase L3 to neutral
Gen voltage phase L1-L2
Gen voltage phase L2-L3
Gen voltage phase L3-L1

The unit is designed for panel mounting. The user should not be able to access parts of the unit
other than the front panel.
Mount the unit on a flat, vertical surface. Before mounting, remove the mounting brackets and
connectors from the unit, then pass the unit through the mounting opening. The unit will be maintained in its
position by the mounting brackets spring.
The output of the current transformers shall be 5 Amperes. The input current rating of the current
transformers may be selected as needed (between 10/5 and 9000/5 amps). Current transformer outputs
shall be connected by separate cable pairs from each transformer, to related inputs. Never use common
terminals or grounding. The power rating of the transformer should be at least 5 VA. It is recommended to
use 1% precision transformers.
Programmable digital inputs are compatible with both
‘normally open’
and
‘normally closed’
contacts, switching either to
BAT-
or
BAT+
.
Engine body must be grounded for correct operation
of the unit, otherwise incorrect voltage and
frequency measurements may occur.
