INJECTOR GP-FUEL 4518438 - Caterpillar

parameters related to voltage regulation are listed below.
Rated generator voltage
Generator potential transformer (PT) primary voltage rating
Generator potential transformer (PT) secondary voltage rating
Voltage set point
Generator frequency
Knee frequency
Integral gain
Derivative gain
Proportional gain
Loop gainOnce startup has been achieved and the generator output frequency is above the corner frequency, the regulator will keep the generator output voltage constant. As changes in generator loading cause the voltage to sag or rise, the regulator will automatically adjust generator excitation to maintain the output voltage. If loading causes the generator frequency to drop below the knee frequency, the loading and stopping profile as previously described will be followed. See System Operation, "Loading And Stopping Profile".The CDVR can be connected to a "Manual Voltage Control". For a wiring diagram of "Manual Voltage Control" see Testing and Adjusting, "Wiring diagrams".A remote voltage adjust toggle switch may be used to fine-tune the generator output voltage. When used, the active value of voltage reference may be adjusted 10%.Voltage can be changed in the software.
The voltage can be changed at the "Settings" screen or the "Metering" screen in the CDVR.
The voltage can be changed at the "Voltage Regulator Control Parameters" screen with the use of Cat ET. One of the following must be done in order to change the new voltage set point.
The "EEPROM" button must be pressed in the CDVR PC software.
The "Enter" key must be pressed in Cat ET after the new set point is entered.
