DKG-307 User Manual V-42 (24.05.2013)
- 24 -
The unit offers 2 sets of voltage and frequency protection limit values. The user is allowed to
switch between these 2 sets anytime.
This feature is especially usefull in dual voltage or frequency gensets for easy switching
between 2 operating conditions.
The switching to the second set of limit values is performed by applying signal to the SPARE-1
digital input.
In order to assign this functionality to the SPARE-1 input, the program parameter P_092
Secondary Volt/Freq should be set to 1.
Below parameters are available for second voltage-frequency selection:
Mains Low Voltage Limit
Mains High Voltage Limit
Mains Low Frequency Limit
Mains High Frequency Limit
Genset Low Voltage Shutdown Limit
Genset Low Voltage Warning Limit
Genset High Voltage Warning Limit
Genset High Voltage Shutdown Limit
Genset Low Frequency Shutdown Limit
Genset Low Frequency Warning Limit
Genset High Frequency Warning Limit
Genset High Frequency Shutdown Limit
Genset Low RPM Shutdown Limit
Genset Low RPM Warning Limit
Genset High RPM Warning Limit
Genset High RPM Shutdown Limit
If the unit is used in a single phase electrical network, it is advised t set the Single Phase
Enable program parameter in CONTROLLER CONFIGURATION group to 1.
When Single Phase Enable is set to 1, then the unit will measure electrical parameters only
on phases L1 of genset and mains.
Voltage and overcurrent checks will be performed on phases L1 only.
Phases L2 and L3 parameters, as well as phase-to-phase voltages are removed from
display screens.
The unit is capable to be programmed to ask for a password when AUTO or RUN mode is
selected.
The password is adjusted with parameter P_115. If the password is set to zero, then the unit
will not ask for password.
When the unit asks for password, enter the password with and buttons, then
acknowledge with MENU button.
6.27. Password Operation (applicable only to DKG-317CAN/MPU)
6.26. Single Phase Operation
6.25. Dual Voltage and Frequency
