2. INPUTS AND OUTPUTS
12V JUMPER:
When this jumper is placed, 12V-DC operation is selected. Do not operate a 12V-DC unit with
a 24V-DC system. This may cause the destruction of the unit. Always disconnect the voltage selector jumper
of a stocked unit.
RS-232 SERIAL PORT:
This connector provides serial data input and output for various purposes like
software update, remote monitoring, remote control, remote programming, etc.
EXTENSION CONNECTOR (OPTIONAL):
This connector is intended for the connection of input and output
extension modules. The optional relay extension module provides 8 programmable 16A relay outputs. The
DKG-705 allows the use of up to 2 I/O extension modules.

Description
1
GENERATOR CONTACTOR
Relay output, 10A-AC This output provides energy to the generator
contactor. If the generator phases do not have
acceptable voltage or frequency values, the
generator contactor will be de-energized. In
standard genset applications, in order to
provide extra security, the normally closed
contact of the mains contactor should be
serially connected to this output. In
‘no break
transfer’
or
‘parallel
with
mains’
applications, this output will drive directly the
generator contactor.
