MTS Criterion™ Series 60 Product Manual 42 Safety
Know the causes of
unexpected crosshead
motions
The high force and velocity capabilities of MTS systems can be destructive and
dangerous (especially if crosshead motion is unexpected). The most likely causes
of unexpected crosshead response are operator error and equipment failure due to
damage or abuse (such as broken, cut, or crushed cables and hoses; shorted wires;
overstressed feedback devices; and damaged components within the control
loop). Eliminate any condition that could cause unexpected crosshead motion.
Do not use RF
transmitters
Keep radio frequency (RF) transmitters away from the workstation computers,
remote terminals, and consoles. Intense RF fields can cause erratic operation of
the more sensitive circuits in the system.
Operations for b all
relief valves
Rotate the handle of ball valve and make sure the handle is parallel with the
pipe,that is the "open" position.
