Be Aware Of Component Movement With Hydraulics Off; Know Electrical Hazards; Ensure Correct Cable Connection; Keep Bystanders Safely Away - MTS Systems Landmark 370 Series Product Information

Safety
An important consideration for servohydraulic systems is that when power is interrupted, it is likely that
stored accumulator pressure will persist for some time within the system. In addition, it is likely that as
stored energy dissipates, gravity will cause portions of the system to move.

Be aware of component movement with hydraulics off

For hydraulic systems, be aware that mechanical assemblies can shift or drift due to changes within
hydraulic hardware when hydraulics are turned off. This non-commanded movement is because oil
can transfer between the pressure and return ports and across internal components of the hydraulic
hardware. Be aware that this can happen, and clear the area around the mechanical assemblies when
hydraulics are turned off.

Know electrical hazards

When the system electrical power is turned on, minimize the potential for electrical shock hazards.
Wear clothing and use tools that are properly insulated for electrical work. Avoid contact with exposed
wiring or switch contacts.
Whenever possible, turn off electrical power when you work on or in proximity to any electrical system
component. Observe the same precautions as those given for any other high-voltage machinery.
Make sure that all electrical components are adequately grounded. Grounds must remain connected
and undisturbed at all times.

Ensure correct cable connection

If a system cable has been disconnected, ensure that you establish the correct cable-to-connector
relationship during reconnection. Incorrect cable connections can result in improper servo loop
phasing or an open servo loop condition, either of which can cause unstable or unexpected and
potentially dangerous system motions. Verify the correct cable-to-connector relationship by observing
the cable and connector labeling and the system wiring schematics.

Keep bystanders safely away

Keep bystanders at a safe distance from all equipment. Never allow bystanders to be in close proximity
of specimens or equipment while the test is running.

Wear proper clothing

Do not wear neckties, shop aprons, loose clothing or jewelry, or long hair that could get caught in
equipment and result in an injury. Remove loose clothing or jewelry and restrain long hair.

Remove flammable fluids

Remove flammable fluids from their containers or from components before you install the container or
component. If desired, you can replace the flammable fluid with a non-flammable fluid to maintain the
proper proportion of weight and balance.
