About the Hydraulic Service Manifold (HSM)
The hydraulic service manifold (HSM), also called the actuator manifold, is a hydraulic component that
controls hydraulic pressure to one work station. The HSM controls are independent of the hydraulic power
unit’s controls. The basic function of the HSM is to provide line pressure regulation.
An HSM contains ports to provide pilot valve filtration, the use of accumulators, and the use of hydraulic
solenoid valves to control the hydraulic pressure to the work station.
The HSM is available with a control voltage of 24 V DC or 115 V AC.
What You Need to Know
This manual assumes that you know how to use your system controller. See the appropriate manual for
information about performing any controller-related step in this manual’s procedures. You are expected
to know how to:
• Turn the system hydraulic pressure on and off.
• Turn the station hydraulic pressure on and off.
