4.6. OUTPUT FREQUENCY INSPECTION AT START-UP
HG hydraulic generators are tested and adjusted at factory but it is recommended
to check the output frequency before taking HG hydraulic generator into operation.
1. Ensure that the generator is properly connected to the hydraulic system of your
base machine and there are no oil leakages in system.
2. Start the engine of your base machine. Adjust the engine speed to demanded
level if necessary.
3. Start the generator with a control valve.

4. Check the output frequency. Use universal true RMS-multimeter. When the
generator is running without load, switch the metering device to the Hz-position
and check the frequency from each socket. Frequency value should be 50 Hz
(60 Hz) ± 5%.
