The failure or shuto of electrical power to the tesng system when pressure is being applied
can cause considerable and unpredictable actuator reacon. Under these condions, loss
of electrical power on servo controlled systems will generally cause the actuator to stroke
at maximum velocity in either direcon or, if a device under test is aached, to apply full
tensile or compressive force. Many systems contain hydraulic/pneumac accumulators that
store enough energy to temporarily operate the actuator at full force capacity even when the
hydraulic/pneumac pressure is shut o. For this reason, the usual interlock devices will not
prevent hazardous actuator stroking. If a power failure does occur, please make sure that Gold
Standard Soware has been reset before powering on the Load Frame. This will protect stop the
connuaon of the previous load selecon.
If servicing the interior components of the hydraulic power supply, power to the unit must be
turned o. Servicing the hydraulic power supply without turning the power o is very dangerous
due to the high voltages present!
