MTS Series 244 Actuators - Manual (Page 37)

Safety Practices While Operating the System
Wear appropriate personal protection
Wear eye protection when you work with high-pressure hydraulic fluid, high-pressure air pressure, breakable
specimens, or when anything characteristic to the specimen could break apart.
Wear ear protection when you work near electric motors, pumps, or other devices that generate high noise
levels. This system may create sound pressure levels that exceed 70 dbA during operation.
Wear appropriate protection (gloves, boots, suits, respirators) whenever you work with fluids, chemicals, or
powders that may irritate or harm the skin, respiratory system, or eyes.
Provide test area enclosures
Use protective enclosures such as cages or shields, and special laboratory layouts when you work with
hazardous test specimens (for example, brittle or fragmenting materials or materials that are internally
pressurized).
Customer must evaluate risks due to ejected parts or materials from the test specimens. If the MTS Test Area
Enclosure option is not selected by the customer, then for protection against ejected parts or materials from
test specimens and to control access to the machinery, the Customer must provide a Test Area Enclosure
to protect personnel.
Specimen temperature changes
During cyclic testing, the specimen temperature can become hot enough to cause burns. Wear personal
protection equipment (gloves) when handling specimens.
Handle chemicals safely
Whenever you use or handle chemicals (for example, hydraulic fluid, batteries, contaminated parts, electrical
fluids, and maintenance waste), refer to the appropriate MSDS documentation for that material and determine
the appropriate measures and equipment required to handle and use the chemical safely. Ensure that the
chemical is disposed of appropriately.
Know servohydraulic system interlocks
Interlock devices should always be used and properly adjusted. Interlock devices are designed to minimize
the chance of accidental damage to the test specimen or the equipment. Test all interlock devices for proper
operation immediately before a test. Do not disable or bypass any interlock devices as doing so could allow
hydraulic pressure to be applied regardless of the true interlock condition. The Reset/Override button is a
software function that can be used to temporarily override an interlock while attempting to start the hydraulic
power unit and gain control of the system.
Know system limits
Never rely on system limits such as mechanical limits or software limits to protect you or any personnel.
System limits are designed to minimize the chance of accidental damage to test specimens or to equipment.
Test all limits for proper operation immediately before a test. Always use these limits and adjust them properly.
Do not disturb sensors
Do not bump, wiggle, adjust, disconnect, or otherwise disturb a sensor (such as an accelerometer or
extensometer) or its connecting cable when hydraulic pressure is applied.
