1. INSTALLATION
1.1 Introduction to the Control Panel
The unit is a control and protection panel used in gensets. It shows the measured values on its
displays. 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 generating set. Programmed
parameters are stored in a Non Volatile Memory and thus all information is retained even in the event of
complete loss of power.
The measured parameters are:
Gen voltage phase U to neutral
Gen voltage phase V to neutral
Gen voltage phase W to neutral
Gen voltage phase U-V
Gen voltage phase V-W
Gen voltage phase W-U
Gen current phase U
Gen current phase V
Gen current phase W
Gen frequency
Gen total KW
Gen total cos
Φ
Battery voltage,
Coolant temperature
Oil pressure
1.2 Mounting the Unit
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. The unit fits into a standard panel meter opening of 151x111
millimeters. Before mounting, remove the retaining steel spring and connectors from the unit, then pass the
unit through the mounting opening. The unit will be maintained in its position by the steel spring.
Engine body must be grounded for correct operation of
the unit, otherwise incorrect voltage and frequency
measurements may occur.
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.
If analogue senders (e.g. temperature or oil pressure) are connected to the unit, it is not possible to
use auxiliary displays, otherwise the unit may be destroyed. If temperature or oil pressure displays are already
present on the generator control panel, do not connect the senders to the unit. The unit is factory programmed
for VDO type senders. However different types of senders are selectable via programming menu. Please
check the programming section.
The programmable digital inputs are compatible with both
‘normally open’
and
‘normally closed’
contacts, switching either to
BAT-
or
BAT+
.
The charge alternator connection terminal provides also the excitation current, thus it is not necessary
to use an external charge lamp.
