PULLEY GP-FAN DRIVE 4W7523 - Caterpillar

parameters that are related to voltage regulation are listed below.:01 - Generator Output Voltage:02 - Ratio of Output Voltage to Sensing Voltage:03 - Generator Type:06 - Knee Frequency:16 - Integral Gain:17 - Proportional GainOnce startup has been achieved and the generator output frequency is above the knee frequency, the regulator will normally act to 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 as set by parameter :01. 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".A remote voltage adjust rheostat may be used to fine tune the generator output voltage. When used, the active value of voltage reference may be adjusted 10% about the value set in parameter :01.
