DKG-509 User Manual V-29
(23.08.2013)
- 26 -
In engine control mode, the unit is supposed to control an engine without alternator.
The engine control mode is activated by a program parameter in the
Controller
Configuration
group.
When the
Engine Control Mode
is activated:
-the unit will not display genset AC parameters (volts, amps, kW and pf).
-genset voltage and frequency protections are disabled. However engine rpm protections will
be active.
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 can be done in 2 ways:
-by setting the program parameter
Secondary Volt/Freq
to 1
-with digital input signal
Thus the user has full flexibility for manual or external switching.
If switching is done with digital input signal, one of digital inputs has to be defined as “
2
nd
Volt-
Freq Select
” using “
INPUT FUNCTION SELECT
“ program group.
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
It is strongly recommended to enter correct low and
high rpm limit values in order to enable engine
speed protection.
