DKG-307 User Manual V-01.03 (14.02.2006) 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.

DKG-307 User Manual V-01.03 (14.02.2006) 5. MODES OF OPERATION The modes of operation are selected by pushing the front panel keys. Changing the operation mode while the genset is running will result to a behavior suitable for the new operating mode. For example, if the LOAD TEST mode is selected when genset is running at TEST mode, then the genset will take the load. OFF: In this mode, the mains contactor will be energized if mains phase voltages are within the programmed limits.

DKG-307 User Manual V-01.03 (14.02.2006) 6.2 Sender type Selection The unit has the ability to adapt to any type of oil pressure and temperature senders. The commonly used standard sender characteristics are recorded in memory and selectable from a list. However non standard senders may also be used by entering their characteristics to the table. Oil Pressure Sender Type Selection: The oil pressure sender is selected using parameter P_019.

DKG-307 User Manual V-01.03 (14.02.2006) 6.4 Service Request Display This led is designed to help the periodic maintenance of the genset to be made consistently. The periodic maintenance is basically carried out after a given engine hours (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 SERVICE REQUEST led has no effect on the genset operation.

DKG-307 User Manual V-01.03 (14.02.2006) 6.7 Remote Monitoring and Programming feature. Thanks to its standard serial RS-232 port, the unit offers the remote monitoring and programming The remote monitoring and www.datakom.com.tr internet site. programming PC software may be downloaded from The software allows the visualization and recording of all measured parameters. The recorded parameters may then be analyzed graphically and printed.

DKG-307 User Manual V-01.03 (14.02.2006) 7. WEEKLY OPERATION SCHEDULE In most applications, the genset is requested to operate only in working hours. Thanks to the weekly program feature unwanted operation of the genset may be prohibited. The unit has one programmable turn-on/turn-off time pairs for each day of week. These programmable parameters allow the genset to operate automatically only in allowed time limits. The weekly operation schedule is only active in AUTO mode.

DKG-307 User Manual V-01.03 (14.02.2006) 8. EVENT LOGGING The unit keeps records of the last 12 events in order to supply information for the service personal. The events are recorded with a date and time stamp. The date and time information comes from the internal battery backed-up real time clock circuit of the unit. The real time clock circuit will continue its operation even in power failures. The real time clock is precisely trimmed using the program parameter P_046.

To enter the program mode, press the MENU button for 5 seconds. The program mode is only allowed if the PROGRAM LOCK input (terminal_23) is left open. If this input is tied to GROUND, the program value modification will be disabled to prevent unauthorized intervention. It is advised to keep the PROGRAM LOCK input tied to GROUND.

DKG-307 User Manual V-01.03 (14.02.2006) Parameters from P_143 to P_154 define the ohm-degrees characteristics of the temperature sender. The sender characteristics will be defined using maximum 6 points. The values should be entered in the increasing order of ohm values. For unused points, ohm values should be entered as 0. An example table is given below. The sensor characteristics used in this table are: 38 ºC........342 ohms 82 ºC..........71 ohms 104 ºC........40 ohms 121 ºC........

Pgm 155 Definition Exercise start day and hour Unit - Std Val 168 Description This parameter defines the start day and hour of the exerciser. Values higher or equal to 168 mean that the exerciser is off. The exercise may be selected to start at the beginning of the any hour of the week. The parameter value is the hour count of the start time.

DKG-307 User Manual V-01.03 (14.02.2006) 12. TROUBLESHOOTING The genset operates while AC mains are OK or continues to operate after AC mains are OK: -Check engine body grounding. -AC mains voltages may be outside programmed limits, measure the phase voltages. -Check the AC voltage readings by pressing the MENU button. -Upper and lower limits of the mains voltages may be too tight. Check the parameters P_004 and P_005. Standard values are 170/270 volts. -The hysteresis voltage may be given to excessive.
PAGE 27
DKG-307 User Manual V-01.03 (14.02.2006) When the AC mains fails, the engine starts to run but the unit gives START FAIL alarm and then the engine stops: -The generator phase voltages are not connected to the unit. Measure the AC voltage between terminals U-V-W and Generator Neutral at the rear of the unit while the engine is running. A fuse protecting the generator phases may be failed. A misconnection may be occurred.
