Power up the Pump and HPU

1. Correct any interlock conditions.

If a limit has been exceeded, see

Recover from a Tripped Displacement Limit

or

Recover from a

Tripped Force Limit

.

2. Power up the HPU (hydraulic pump unit) and HSM (hydraulic service manifold).

Once all issues and interlocks are corrected and the crush zone is clear, power up the HPU only using
the accepted procedure for your lab. This will provide power to the grips only, making for a safer
installation of the specimen into the lower grip.

Note: HPU setups vary considerably by lab. This document describes a typical HPU setup. For
more information, consult your lab experts or system documentation.

3. Reset the interlock.

Click the Reset button. If the interlock will not reset, a condition like the enclosure door not being shut
or the actuator velocity limiting switch being in turtle mode is likely preventing the interlock from resetting.
