MTS Model 293-22 Hydraulic Service Manifold - Manual (Page 34)

HSM Site Preparation
Consider the following items for site preparation:
• The HSM must be installed in an area that is protected from extreme temperature and humidity. An
environment with a non-corrosive atmosphere is recommended.
• The HSM must be located as close as possible to the servovalve(s) it supplies. The maximum allowable
distance must take the specific system dynamic flow transient requirements and turn-on/turn-off transient
requirements into account. For assistance in calculating these factors, contact MTS Systems Corporation.
• MTS recommends that you install a shut-off valve and lock-out tag on each HSM to ensure that HPU
pressure is not applied to an HSM being serviced.
• To prevent movement of equipment due to hydraulic line transients, the recommended mounting method
includes anchor bolts set in concrete to a steel framework.
• If you have a multi-channel HSM configuration, MTS recommends that you install a shut-off valve and
lock-out tag on each HSM to ensure that HPU pressure is not applied to an HSM being serviced.
Model 293.22 HSM Hydraulic Connections
For a single-channel HSM, all hydraulic connections are made on the main manifold. In a multichannel
operation, the actuator and servovalve connections are made at the associated control manifold ports; the
HPU connections are made at the main manifold.
