FRAME AS 4517935 - Caterpillar

Initial Start-Up
Measure the insulation resistance of each winding if the generator was exposed to the following conditions:
Rapid changes in temperature
Freezing
Wet climate during shipment
Wet climate during storageRefer to this Operation and Maintenance Manual, "Insulation - Test".Note: These tests should be conducted prior to any power connections or control connections that are being made.Starting

Readjust the governor for rated frequency. Adjust the Voltage (R220, R250, and R251)
Adjust the voltage regulator in order to obtain the proper voltage. Refer to Operation and Maintenance Manual, "Voltage Regulators" for more information about the voltage regulator.Adjust the Voltage (R438)
Adjust the voltage regulator in order to obtain the proper voltage. Refer to Operation and Maintenance Manual, "Voltage Regulators" for more information about the voltage regulator.Stopping
