Note:
A station interlock prevents an HSM start but permits an HPU start. The HSM is a station resource
and cannot start when a station interlock is active. An HPU is considered an external device and
can be started with an active station interlock (even if it has caused the interlock).
3. Turn on the HSM.
a) Click HSM Power Low.
b) Click HSM Power High.
When possible, use low pressure to install specimens.
How to Turn Off Hydraulics
On the Station Manager window’s Station Controls panel:
•
To turn off the HSM, click HSM Power Low and then HSM Power Off.
•
To turn off the HPU, click HPU Power Low and then HPU Power Off.
•
To simultaneously turn off both the HSM and HPU, click All Off.
About House Pressure Systems
A house pressure system uses a hydraulic pressure source that is not controlled or monitored by an MTS
controller. Because the controller does not control or monitor the pressure, you must manually control the
integrator to minimize actuator movement when you apply hydraulic pressure to the system.
How to Load a Station that Uses House Pressure
Use this procedure to load a station that does not control or monitor the hydraulic pressure source.
1. Ensure that hydraulic pressure is off.
Warning:
Unexpected actuator movement can occur when hydraulic pressure is applied to a station
that does not control or monitor hydraulic pressure.
Unexpected actuator movement can result in injury to personnel or damage to the equipment.
Follow these guidelines to minimize actuator movement when you apply hydraulic pressure
to a system that does not control or monitor hydraulic pressure: Ensure that the hydraulic
pressure is off before loading a station. Make sure that the mechanical and electrical valve
balance is set correctly. Before you apply hydraulic pressure to the system, use the Station
Manager Manual Command control to manually zero (or minimize) the error signal, disable
the integrator, and ensure that all program sources are off.
2. Load a station.
