Control group
[ ]
Defines the logical group which links this gen-set with other gen-sets on the CAN bus. The gen-sets in each
logical group make the Load Sharing and VAr Sharing independently on other groups, allowing more such
groups to be present on the CAN bus. Groups can be linked together using GroupLink tools.
Step:
1
Range:
COMMON (=1), 2 – 32
GroupLinkLeft
GroupLinkRight
[ ]
These setpoints define the gen-set groups present to both sides of a special breaker. The information about
the breaker status is sent to all controllers via CAN bus and the affected controllers will behave according to
it.
Step:
1
Range:
COMMON (=1), 2 – 32
Hint:
Example: if settings are GroupLinkLeft = 1 and GroupLinkRight = 2 and the special breaker is closed, a CAN
message is sent to notify all gen-sets in groups 1 and 2, that they should work together and make Load and
VAr Sharing not only within their groups, but together with the other group, too.
The message is sent if logical binary input GroupLink is active, and this signal should be linked to the
feedback of the special breaker (e.g. Bus-tie).
Sync/Load ctrl
SpeedRegChar
[ POSITIVE / NEGATIVE ]
Switch between speed governor characteristic.
POSITIVE: When the controller Speed governor output voltage increases – engine speed increases.
NEGATIVE: When the controller Speed governor output voltage decreases – engine speed increases.
Hint:
When set to NEGATIVE, Binary outputs Speed Up and Speed Dn still work without inversion.
Voltage window [ % ] (FV)
Maximum difference between generator and mains/bus voltage.
Step:
0,1 % of
GenNomV
Range:
0,0 – 100,0 % of
GenNomV
Force value possibility: Yes
Hint:
See Voltage phases match indication on the controller Synchronizing screen.
Example 1.
Voltage match 1 2 3
Note:
1 1 0
Phase L3 is out of voltage window
Example 2.
Voltage match 1 2 3
Note:
1 1 1
All phases are in voltage window
GtoM AngleReq
[
°
]
Requested phase difference between generator and mains voltage during synchronizing. Use this setpoint
for phase correction of potential transformers connection.
Step:
1
°
Range:
-45
°
to +45
°
Following is an example of the controller connection to a high voltage system.
T1 shifts phase +30
°
and no shift is on T2.
GtoM AngleReq
= +30
°
for this example.
