Program Group: 10
This group of programs defines the No Break Transfer and Parallel with Mains feature
characteristics.
This group is reserved for factory and qualified installation personal and
must not be modified by end users or non-qualified service personal.
Otherwise severe damage may occur.
Group Param. Definition Unit Min Max Description
10 A00 No Break Transfer - 0 1 0: No break transfer disabled.
1: No break transfer enabled.
10 A01 Soft Transfer
Enable
- 0 1 0: Soft transfer disabled.
1: Soft transfer enabled.
10 A02 GOV Control
Enable
- 0 1 0: Governor control disabled.
1: Governor control enabled.
10 A03 GOV Reverse
Polarity
- 0 1 0: Governor control normal polarity (speed
increases with voltage increase).
1: Governor control reverse polarity (speed
decreases with voltage increase).
10 A04 AVR Control
Enable
- 0 1 0: AVR control disabled.
1. AVR control enabled.
10 A05 AVR Reverse
Polarity
- 0 1 0: AVR control normal polarity (voltage
increases with resistor decrease).
1: AVR control reverse polarity (voltage
decreases with resistor decrease).
10 A06 Ignore Phase
Order
- 0 1 0: Phase order check enabled. This option is
used in 3 phase gensets.
1: Phase order check disabled. This option is
used in single phase gensets.
10 A07
Synchronization
Fail Timeout
Sec. 0 60 If the phase and voltage synchronization is not
successful before the expiration of this timer,
then a Synchronization Fail Warning is given
and the DKG-705 renounces the No Break
Transfer and makes a conventional
changeover.
10 A08
Soft Transfer
Timer
Sec. 0 60 This is the time duration of the Soft Transfer.
At the end of this timer one of the contactors
will release to terminate the parallel operation.
10 A09 Contactor
Timeout
Sec. 0 5 This is the maximum time duration in which
both contactors are active in case of No Break
Transfer . It is advised to set this timer to
0.5sec.
10 A10
Max Frequency
Difference
Hz 0.1 2.0 This is the maximum difference between mains
and genset frequencies to enable a NO Break
Transfer . Note that the DKG-705 adjusts the
GOV output to bring the genset to the same
frequency with the mains.
10 A11 Max Voltage
Difference
V 0 20 This is the maximum difference between the
mains phase-R and the genset phase-U
voltages to enable a NO Break Transfer . Note
that the DKG-705 adjusts the AVR output to
bring the genset to the same voltage with the
mains.
