How to Recover from a Thermal Overload
Note Recovering from a thermal overload only applies to the Model 685.10
and Model 685.22 Hydraulic Grip Supplies.
A thermal overload can cause the hydraulic grip supply to turn off unexpectedly.
To recover from a motor thermal overload:
Do not operate a hydraulic grip supply that has a recurring thermal overload
of the motor.
When the motor experiences a thermal overload, the motor stops and
hydraulic pressure to the grips decreases. This causes the grips to release.
If a test is underway, the specimen can break and damage your equipment.
Contact your local MTS Service Representative.
