Description
4508
Process
droop
2 0.0 to 100.0 % 0.0 % The Process droop is the load droop desired based on process
level.
4509
Process filter
2
0 to 8
0
The Process filter adjusts the bandwidth of the filter on the
process input. Higher frequency settings result in faster control re-
sponse, but also more response to process noise.

Process
reference
2
-999999.9 to
999999.9
0.0
The Process reference is the internal reference for the process
control. The process engineering units are determined by the se-
lection and settings in Menu 6.1.
4504
Raise
reference
rate
2
0.01 to 20.00
%/s
0.10 %/s
The Raise reference rate is the rate at which the process refer-
ence is increased when the DI “Load Raise” command is acti-
vated.
4505
Lower
reference
rate
2 0.01 to 20.00
%/s
0.10 %/s The Lower reference rate is the rate at which the process refer-
ence is decreased when the DI “Load Lower” command is acti-
vated.

Process
control
action
´2
Direct / Indirect
Direct
The
Process control action
specifies if the process variable is di-
rect or indirect acting.
Direct: If the process variable increases when generator load in-
creases.
Indirect: If the process variable decreases when generator load
increases.

7500
Process high
limit alarm
2
Disabled./.
Enabled
Disabled
The Process high limit alarm specifies if the high process limit
alarm is activated.
4510
Process high
limit PU
2 0.0 to 150.0 % 75.0 % The Process high limit PU is the process input level where (if
enabled) the “High Limit” relay output is energized and the high
limit alarm is activated.
4511
Process high
limit DO
2
0.0 to 150.0 %
75.0 %
The Process high limit DO is the process input level where (if
enabled) the “High Limit” relay output is de-energized and the high
limit alarm is deactivated.
7501
Process low
limit alarm
2
Disabled./.
Enabled
Disabled
The Process low limit alarm specifies if the low process limit alarm
is activated.
4513
Process low
limit PU
2
0.0 to 150.0 %
50.0 %
The Process low limit PU is the process input level where (if
enabled) the “Low Limit” relay output is energized and the low limit
alarm is activated.
4514
Process low
limit DO
2 0.0 to 150.0 % 50.0 % The Process low limit DO is the process input level where (if
enabled) the “Low Limit” relay output is de-energized and the low
limit alarm is deactivated.
7502
Process
switches
2
Disabled./.
Enabled
Disabled
The Process switch specifies if the process high and low limits will
activate the “High Limit” and “Low Limit” relay outputs.
