By default, these are set to active low. Polarities of these contacts can be set only in Preset 1 in case of the This permits the integration of the regulator as a node on A fault output contact is provided through terminals P, P and -P1- a CAN network.

There are two automatic voltage regulation modes. AVR1 should be se- lected if the regulator is connected for single phase voltage sensing and Power Input Stage AVR3 should be selected if the regulator is connected for three phase volt- Input power is applied to terminals 3 and 4 from a PMG.
It is rectified and age sensing. In either mode, the regulator regulates the generator RMS filtered before being applied to the power amplifier and the power supply. Regulation is accomplished by sensing generator output voltage and adjusting dc output excitation current to maintain voltage at Power Supply the regulation set point.

When three-phase current sensing is used, The regulator provides a mode in which an auxiliary voltage of 0 to the droop function responds to the average phase current. See Figure The regulator incorporates an adjustable soft start feature that controls the time for generator voltage to ramp to the regulation set point.
The ramp rate is adjust- able from 2 to seconds default of 3 seconds. This adjustment is made through the portal and cannot be made through the HMI. The Generator Under Frequency feature is also active during Generator Soft Start and takes priority in control of the generator voltage.
