Valve Adjustment
The valve tube has seals located on the top and bottom of the tube. The vertical position of the tube when
in the closed position determines the amount of valve sealing. The valve is adjusted at the factory to its
correct position and should not require field adjustment under normal conditions.
Following major valve maintenance such as seal replacement or drive cable replacement, the valve
adjustment should be checked. If the valve is adjusted too high, it will leak. If the valve is adjusted too low,
the motor protection circuit may be activated.
Determine the current state of valve adjustment as follows:
•
Power up the bucket circuit to allow the valve to move to the closed position.
• If the indicator lamp flashes green or the cable drum / sensor cam oscillates when the
valve is closed, then the valve is adjusted too low.
•
Actuate the bucket dump switch and hold to keep the valve in the open position.
• If the indicator lamp flashes green or the cable drum / sensor cam oscillates when the
valve is open, then the valve is adjusted too high.
The adjustment procedure is as follows:
•
Power up the bucket circuit to allow the valve to
close.
•
Remove power from the bucket circuit.
•
With the valve in the closed position, locate the
set screw on the top of the sensor cam which
locks the cam to the cable drum. It should be at
approximately the 12 o'clock position.
