DKG-705 AUTOMATIC MAINS FAILURE AND REMOTE START ...

DATAKOMDKG-705 User’s Manual1.2 Mounting the UnitThe unit is designed for panel mounting. The user should not be able to access parts of the unitother than the front panel.Mount the unit on a flat, vertical surface. The unit fits into a standard panel meter opening of 188x140millimeters. Before mounting, remove retaining steel springs from the unit, then pass the unit through themounting opening. The unit will be maintained in its position by the steel springs.The DKG-705 is factory set for 24V-DC operation. If the unit is used in a 12V-DC system, the 12Vjumper terminals must be short-circuited.Do not operate a 12V-DC unit with a 24V-DC system. Thismay cause the destruction of the unit. Always disconnectthe voltage selector jumper of a stocked unit.The engine body must be grounded for correct operation of the unit. Otherwise incorrect voltage andfrequency measurements may occur, resulting in faulty operation of the genset.The output of the current transformers shall be 5 Amperes. The input current rating of the currenttransformers may be selected as needed (between 50/5 and 2500/5 amps). Current transformer outputs shallbe connected by separate cable pairs from each transformer, to related DKG-705 inputs. Never use commonterminals or grounding. The power rating of the transformer should be at least 5 Watts. It is recommended touse 1% precision transformers.If analogue sensors (e.g. temperature, oil pressure, oil temperature or fuel level) are connected toDKG-705, it is not possible to use auxiliary displays. If temperature or oil pressure displays are already presenton the generator control panel, do not connect the sensors to the DKG-705. The unit is factory programmedfor VDO type sensors. However if a different type of sensor is to be used, it is possible to recalibrate the unit.The calibration process will be explained later in this document.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 necessaryto use an external charge lamp.705-UE.doc - 4 -
