M** LOAD SENSOR AND DROOP **
Figure 3-24. Service: M** LOAD SENSOR AND DROOP ** Menu
THIS MENU IS USED TO SET UP THE GENERATOR LOAD CONTROL PARAMETERS.
01 USE LOAD SENSOR? dflt=FALSE (FALSE, TRUE)
Set to TRUE to use the built in generator load sensor for generator applications or FALSE when using
control for pump, blower, or compressor applications.
02 USE ACT POS DROOP? dflt=FALSE (FALSE, TRUE)
Set to TRUE to use internal LSS demand/actuator position to calculate a droop percentage. When this
setting is TRUE, actuator position feedback is used as the controlling parameter for stability when the unit
is on-line. Droop percentage is set up in Service Menu “M” below. Actuator position levels in Service
Menu “M”, below, must be set properly when this value is set to TRUE. If these values are not set
properly, the droop percentage will be off. When this setting is FALSE, Actuator Position Droop will not be
used.
Note: Do not set this value to True if applying the Potential Transformer and Current
Transformer inputs to calculate the true KW load value.
03 DROOP PERCENTAGE (%) dflt=5.0 (0.00, 12.0)
This value is the percentage of rated speed the speed reference will droop when the generator load is
increased to maximum load. This value is used for KW Droop and Actuator Position Droop.
04 ACT % @ NO LD (POS DRP) dflt=20.0 (0.0, 100.0)
This value is the percentage of actuator output used to calibrate the actuator position droop feedback at
no load. If actuator position feedback droop is used, this value must match the actuator output position at
no load.
05 ACT % @ FULL LD (POS DRP) dflt=80.0 (0.0, 100.0)
This value is the percentage of actuator output used to calibrate the actuator position droop feedback at
full load. If actuator position feedback droop is used, this value must match the actuator output position at
full load.
06 ENTER RATED LOAD (KW) dflt = 1000 (10, 30000)
This value should be set to the generator full load (100%) in kW.
07 LOAD GAIN VOLTAGE dflt=6.00 (0.1, 9.0)
Enter the load gain desired at 100% load. The software will use the Rated KW value above and this Load
Gain voltage value to scale the analog output to the load sharing circuitry to perform load sharing with
other controls in the system. A value of 6.0 is usually sufficient to allow load sharing with other units
utilizing 0–3 Vdc analog load sharing lines. This value must be common with all other controls connected
to the common Load Sharing Signal lines.
08 KW CALIBRATION ZERO dflt=0.00 (-20.00, 20.00)
Adjust until the KW reading is zero when the generator output is zero.
