05 AnIN 2, Gain dflt = 1.000 (0.00
–10.00)
Sets the gain for analog input 2.
06 AnIN 2, mA / Volt (monitor)
Shows the actual input value for input 2.
07 Actuator, Offset dflt = 0.000 (
–100.00–100.00)
Sets the offset for the actuator output. This value should never need adjustment.
08 Actuator, Gain dflt = 1.000 (
–100.00–100.00)
Sets the gain for actuator output. This value should never need adjustment.
09 Actuator Output (monitor)
Shows the actual milliamp output value of the actuator.
10 Anout 4
–20 mA, Offset
dflt = 0.000 (
–100.00–100.00)
Sets the offset of analog output.
11 Anout 4
–20 mA, Gain
dflt = 1.000 (
–100.00–100.00)
Sets the gain of analog output.
12 Anout 4
–20 mA, output
(monitor)
Shows the actual output value.
W**LOAD PULSE SETTINGS**
To enable the Load Pulse and Load Rejection functions, the kW calibration
should be verified since this logic uses the load change as a parameter.
01 ENABLE LOAD REJECT FUNCT dflt = FALSE (TRUE, FALSE)
This parameter enables (TRUE) or disables (FALSE) the Load Rejection logic.
The Load Rejection logic measures how fast the engine load changes in time. If
a large decrease in generator load is detected, the speed reference is decreased
momentarily to compensate for a large speed overshoot.
02 LOAD REJECT DERIV %/S dflt = -10.00 (
–1000.00–5000.00)
This value represents the level of change in generator load at which the Load
Reject logic is activated for large load rejections. When this level is reached, the
load step value used with the value “03 LS REJECT MULT ACT %/S” is
subtracted from the actuator output.
03 LD REJECT MULT ACT dflt = 1.000 (
–100.00–100.00)
This represents the value that multiplies the measured load rejection step and
subtracts this from the actuator output in case of a large load rejection. This step
is momentary and will return to zero. The rate at which this happens can be
modified in “04 LD REJ RECOVER RATE %/S”.
04 LD REJ RECOVER RATE %/S dflt = 15.00 (0.00
–1000.00)
This value determines the rate (actuator %/S) at which the actuator pulse is
ramped back to zero.
05 ENABLE LOAD PULSE FUNCT dflt = FALSE (TRUE, FALSE)
This parameter enables (TRUE) or disables (FALSE) the Load Pulse logic. The
Load Pulse logic measures how fast the generator load changes in time. If a
large increase in engine load is detected, the speed reference is increased
momentarily to compensate for a large speed undershoot.
