2. INSTALLATION 2.1 Introduction to the Control Panel The control panel 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. -
Page 5: Inputs And Outputs
1) ALWAYS remove the plug connectors when inserting wires with a screwdriver. 2) ALWAYS refer to the National Wiring Regulations when conducting installation. 3) An appropriate readily accessible disconnection devices (e.g. automatic fuses) MUST be provided as part of the installation. 4) The disconnection device must NOT be fitted in a flexible cord. - Page 6 2) STOP RELAY: The relay will operate during programmed period in order to stop the engine (Activate to Stop) 3) PREHEAT RELAY: The relay will operate the programmed delay before the cranking of the engine. It will be deactivated during cranking and reactivated during the rest period between cranks.

2.5 Digital Display This display shows: - (R) phase voltage, when mains are on - Alternator frequency, if the generator is on - Program values in program mode Below values can be read in sequence by pushing the MENU key in AUTO or TEST modes: - (R) phase voltage - (S) phase voltage... -
Page 9: Periodic Maintenance Request Display
(for example 200 hours), but even if this amount of engine hours is not fulfilled, it is performed after a given time limit (for example 12 months). The DKG-205 has both programmable engine hours and maintenance time limit. The engine hours is programmable between 0 and 750 hours at 50-hour steps, the time limit is programmable between 0 and 15 months. - Page 10 ALTERNATOR HIGH TEMPERATURE ALARM: It turns on if a signal comes from the high temperature switch of the alternator. WARNING: This switch shall be normally closed, and open in case of excess of heat. If this input is not used, connect it to DC Supply negative terminal, else an alarm will be given continuously.

Page 11: Modes Of Operation
2.9 Modes of Operation The modes of operation are selected by pushing the front panel keys. If the mode is changed while the engine is running, it will be stopped. Do not change the operation mode while the generator is in operation. OFF: In this mode, the mains contactor will be energized if mains phase voltages are within the programmed limits. -

PROGRAM: It is used to program the timers, operational limits and the configuration. 3. MAINTENANCE WARNING: DO NOT OPEN THE UNIT There are NO serviceable parts inside the unit. Wipe the unit, if necessary with a soft damp cloth. Do not use chemical agents. - Page 13 When the AC mains fails the unit energizes the fuel solenoid, but does not start, also OIL PRESSURE ALARM led flashes: The unit is not supplied with battery (-) voltage at the oil pressure input. -Oil pressure switch not connected. -Oil pressure switch connection wire cut.

5. PROGRAMMING The programming mode is used to program the timers, operational limits and the configuration of the unit. To enter the program mode, press the PGM button. The display shows (Pr) when program mode is selected. When the MENU key is pressed the program number will be displayed, when it is released the program value will be shown. - Page 15 P14=MAINS WAITING TIMER: This is the time between the mains voltages entered within the limits and the generator contactor is deactivated. P15=COOLING TIMER: This is the period that the generator runs for cooling purpose after the load is transferred to mains. P16=MAINS CONTACTOR TIMER: This is the period after the generator contactor has been deactivated and before the mains contactor has been activated.
