Operation Instructions
The hydraulic control assembly is designed to work with a digital controller with PWM signal output. As the
signal current increases, the hydraulic flow control valve opens.
To ensure proper hydraulic oil flow metering, follow the calibration procedure described by the manufacturer of
the controller that is being used as each controller’s procedure is different. In general, balancing reaction time
and system stability are key to proper calibration.
The hydraulic flow control valve has a manual override option fitted from the factory. This feature can be used
to open or close the valve in the event that the digital controller has an error or fails. To use this feature,
remove the override cover on the top of the valve to reveal the red override toggle. The override is engaged by
turning the toggle clockwise. One full turn is required to start opening the valve and full open is achieved with
6 full turns. To close the valve, turn the toggle counter clockwise 6 turns until a stop is reached.
Connections to the control assembly are SAE #10 (7/16-14 UNF-2B) O-ring boss ports. Ensure that the mating
fitting has an O-ring free of any debris or damage before installation.
Match the high pressure line to the port labelled “IN” and the low pressure line back to tank to the port
labelled “OUT”.
The port labelled “BYPASS” is a SAE #8 (3/4-16 UNF-2B) port intended return excess oil flow back to the
reservoir. This port comes plugged from the factory. When plugged, the hydraulic control assembly can
be used with hydraulic circuits that have a variable displacement pump. If the hydraulic circuit uses a fixed
displacement pump, the plug must be removed and a line should be run from the bypass port to the reservoir.
The maximum input flow is 30 GPM (114 LPM) for the bypass configuration.
