Series 505G2 SilentFlo™ Hydraulic Power Unit 27
Ensure secure cables
Do not change any cable connections when electrical power or hydraulic pressure is applied. If you
attempt to change a cable connection while the system is in operation, an open control loop condition
can result. An open control loop condition can cause a rapid, unexpected system response which can
result in severe personal injury, death, or damage to equipment. Also, ensure that all cables are
connected after you make any changes in the system configuration.
Stay alert
Avoid long periods of work without adequate rest. In addition, avoid long periods of repetitious,
unvarying, or monotonous work because these conditions can contribute to accidents and hazardous
situations. If you are too familiar with the work environment, it is easy to overlook potential hazards that
exist in that environment.
Contain small leaks
Do not use your fingers or hands to stop small leaks in hydraulic or pneumatic hoses. Substantial
pressures can build up, especially if the hole is small. These high pressures can cause the oil or gas to
penetrate your skin, causing painful and dangerously infected wounds. Turn off the hydraulic supply
and allow the hydraulic pressure to dissipate before you remove and replace the hose or any
pressurized component.
Stay clear of moving equipment/avoid crush points
Stay clear of mechanical linkages, connecting cables, and hoses that move because you can get
pinched, crushed, tangled, or dragged along with the equipment. High forces generated by the system
can pinch, cut, or crush anything in the path of the equipment and cause serious injury. Stay clear of
any potential crush points. Most test systems can produce sudden, high-force motion. Never assume
that your reactions are fast enough to allow you to escape injury when a system fails.
Know the causes of unexpected actuator motions
The high force and velocity capabilities of MTS actuators can be destructive and dangerous (especially
if actuator motion is unexpected). The most likely causes of unexpected actuator 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
servocontrol loop). Eliminate any condition that could cause unexpected actuator motion.
Do not use RF transmitters
Keep radio frequency (RF) transmitters away from the workstation computers, remote terminals, and
electronics consoles. Intense RF fields can cause erratic operation of the more sensitive circuits in the
system.
Know compressed gas hazards
Some environmental chambers use liquid nitrogen or some inert gas to achieve a required test
atmosphere. Typically these gasses are supplied in pressurized tanks.
Observe the following safety practices when you work with high-pressure air or gases:
