Operating faults and preventative measures
• Blockage of carriage on return passage
– If the carriage return is obstructed, the overload safety device will be activated.
– The trapezoidal thread nut (14) is released from the sliding carriage (12).
– The trapezoidal thread nut (14) moves to the safety position for return passage (17) of the drive shaft (6).
– The machine has to be stopped with the key
– In case machine is in modus «Wait for Initialize», operate spacer (13) manually.
– Start the machine with the key
– Move the trapezoidal thread nut (14) to the thread start for return passage (19) by hand. The trapezoi-
dal thread nut (14) is caught by the drive shaft (6) and moved in test direction.
– If at least one pitch of the screw thread on the drive shaft (6) is visible on the left hand side of the trapezoi-
dal thread nut (14), stop the machine with the key
– Push the sliding carriage (12) by hand until it stops at the trapezoidal thread nut (14).
– Switch off the machine with main switch (2) and switch it on again.
– Re-initialize the machine according to operating instructions on page 4.
• Overload safety device in test direction
– If the maximum allowable tensile load is exceeded, the machine switches off automatically to prevent
damages.
– Relieve probe by pushing the key
– Remove sample.
– Fasten new sample and repeat test.
• Engine overload current
– The device always measures the engine record current. If the current exceeds the maximum permissible
current the engine is adjusted by reducing the engine speed. The < symbol appears on the display.
– Switch off drive with
– Remove sample.
– Clamp new sample and repeat test.
• Overrunning the end of drive shaft in test direction
– If the end of the test run is not recognised, the sliding carriage (12) goes to the safety position for
test direction (18).
– Stop machine with
– Start machine with
– Bring sliding carriage (12) by hand to the thread start for test direction (20).
– If at least one pitch of the screw thread on the drive shaft (6) is visible on the right hand side of the sliding
carriage (12), stop the machine with the
– Switch off the machine with the main switch (2) and switch it on again.
