Section 3 - Operation
Hydraulic Operation -
When the bottom of the switch is depressed, light (3) in the switch will begin to flash.. This is an indication to the operator that a timed sequence must be programmed into the EHR controller.. The light will continue to flash for ten seconds to allow time for the operator to begin the programming sequence..
If a program is not started within this ten second period, the controller will not accept any sequence and the remote control lever (2) will not remain latched in either the extend or retract positions..
To program the EHR system, first ensure that the cylinder hydraulic hoses are properly connected to the appropriate rear remote valve.. Start the tractor engine and ensure the EHR engagement switch is up/on.. Set the tractor engine RPM’s at the normal operating speed in which the cylinder is to be operated.. This is important as the programming of the control levers is based on a time interval to correspond to the time it takes the cylinder ram to extend as well as retract.. Any change in engine rpm will have an effect on hydraulic flow (GPM) and therefore the time it takes the cylinder to extend and retract.. The control lever timed program always remains the same regardless of oil flow (GPM) until reprogrammed.. Therefore consistent operation is required for the system to operate correctly.. Using the corresponding color coded programming switch (1) depress the bottom of the switch so light (3) begins to flash.. While the light is flashing use control lever (2) to extend the cylinder.. As soon as the control lever is activated the programming light will go on solid.. Hold the lever until the cylinder is extended to the desired position and then return the lever to the neutral position.. When the lever is returned to the neutral position the programming light will once again begin to flash indicating that the retract phase of the cycle needs to be programmed..
Next use lever (2) to retract the cylinder.. As soon as the lever is activated the programming light will go on solid.. Hold the lever until the cylinder is retracted to the desired position and then return the lever to the neutral position.. After the second phase has been completed the programming light will go out indicating that the programming has been memorized.. The lever timed operation is now programmed for the extend and retract operation of the cylinder..
Repeat the above sequence to program the remaining levers..

Programming of the lever can be performed in either sequence, extend/retract, retract/extend or one sequence only, extend or retract.. The program for the individual lever (2) will remain the same even when the engine is stopped and the ignition switch is in the off position, as long as the programming switch
(1)remains in the program position as shown.. The maximum allowable time limit for any programmed timed operation is two minutes..
Programming the lever with the engine and hydraulic flow off is possible however accuracy of actual operation will be marginal.. Whenever a hydraulic application is changed, the lever should be reprogrammed to suit the new operation..
When operating in the timed programmed mode, feathering of the hydraulic flow is possible by moving the lever variably anywhere between the neutral position and the fully opened position.. The timed operation sequence only begins once the lever has been locked in the fully opened position..
Should the lever be moved to the float position no timed program is possible and the lever must be returned back to neutral manually..
