3.10 Calibration of the electronic governor
To calibrate the electronic governor, perform the following steps:
1. Begin calibration procedure with 1150/1155 HAYBUSTER TUB GRINDER Tub Grinder completely
shutdown. Place the MODE switch in the OFF position and the RANGE switch in the H‑High position.
Rotate the TUB SPEED KNOB fully clockwise toward the rabbit position. Turn the ENGINE LOAD
KNOB fully clockwise, and switch the MODE switch to ENGINE (Auto) Position.
2. Verify that fluid coupler is disengaged. Inspect machine to verify that all personnel are clear of the
machine.
3. Start engine and run the grinder at about 1/2 throttle to allow the hydraulic system to warm up before
calibrating the RCB93 Electronic Governor.
4. When the system has reached operating temperature, throttle the engine to under 1500 RPM. Engage the
rotor and tub drive then throttle up to 1800 RPM. The FUSE light and the SENSOR light should come
on. The tub should not be rotating at this time. If the tub is rotating, read section 6.1 “Troubleshooting the
electronic governor system” in this manual.
5. Slowly rotate the ENGINE LOAD KNOB counter‑clockwise until the tub just begins to move. The tub
should begin to rotate. If it does not begin to rotate, switch the range switch to M-Medium or L-Low and
repeat as necessary.
TEST:
Throttle the engine down and the tub should stop rotating, return the engine to 1800 RPM and the tub should
start to rotate.
If the tub will not rotate, read section 6.1 “Troubleshooting the electronic governor system” in this manual.
3.11 Adjusting the tub’s rotation speed
Tub rotation is controlled by two components or remote radio. The tub is started, stopped and reversed by a switch on
the control panel or the remote radio control and the tub’s rotation speed is controlled by the tub limit knob (tub speed
knob) on the electronic governor.
