Adjustments
1. Connect a digital multimeter
(DMM) with a frequency counter to
the 110 vac outlet. Adjust the
potentiometer until a frequency of
66.5 HZ is obtained with no load
on the generator.

Modification note
Replace two position terminal strip #45 and use 74911
four position terminal strip in its place. Use the
name plate from the old two position terminal.
Add three Genie P/N 45762 6 amp 200 PIV diodes in
the position shown in the schematic.
Theory of Operation
1. Turning on the Generator supplies current to the high idle relay
through the diode switching the engine to high RPM. In addition
the diode between TB45 and TB29 supplies power to the motor
stroke valve switching the motors to high speed/low torque mode.
2. The SX controller is turned ON supplying power to bypass valve
and the change over relay. The EDC valve is switched over to
the output of the SX controller.
3. When the AC generator is turned OFF the SX module will ramp
the output to the EDC to threshold preventing cavitation to the
hydraulic motor powering the generator. When threshold is
reached the bypass valve is turned OFF.
4. The time delay module keeps the SX controller ON for four
additional seconds after the ESTOP is pressed allowing for a
controlled ramp down of the generator.
