Section 2: Introduction
2.1 Dry Clutch
The
HPTOTM Hydraulic Power Take off
is hydraulically actuated, enclosed dry clutch that requires no adjustment
throughout its wear life. During a torque spike, the clutch will act as a torque limiter by slipping to absorb the shock
load. The bearings in the clutch are grease for the life of the product.
A
Microprocessor Controller
provides remote push button controlled clutch engagement of the HPTO. The controller
monitors clutch pressure, engine speed and equipment safety switch.
A
Hydraulic Manifold Assembly
controls the pressure required for clutch engagement. System components include a
DC coil, a pressure regulating cartridge, and a pressure switch.
The pre-programmed setting of the controller determines how the HPTO unit will function during start up.
The “Power” LED illuminates to notify the operator that the controller is receiving switched power from the engine
ignition switch.
The “Engine RPM” LED illuminates when the engine is running.
To engage the clutch, set the engine rpm below 1100 rpm, press and hold the “Engage/Disengage Button” for 3
seconds. Once the “Clutch Engage Symbol” illuminates, the reset button can be released. The controller will begin the
engagement of the clutch and perform a series of “bumps” to bring the driven equipment up to engine speed.
Note that there is a safety switch that prevents the rotor from engaging when the disc cover is raised.
If the engine speed is above 1100 rpm while attempting to engage the clutch, the “Engine Over-speed Symbol” will
illuminate. Reduce speed below 1100 rpm and the light will turn off.
To disengage the clutch, set engine speed below 1200 rpm and push the “Engage/Disengage Button”. The clutch will
immediately disengage.
