Should the problem continue the micro switch actuator may need to be adjusted?
To check if the start button is faulty, try to start the machine with the foot switch.
Check the connector and magnet at the electrical module.
If the clamp bar snaps down on the release of the start button, this indicates that the 15
microfarad capacitor needs to be replaced.
Should the machine cause blown fuses or trip your circuit breakers, it is likely that the bridge
rectifier is blown.
Full clamping not operating
If you are not achieving a full clamp, the angle micro switch may not be fully actuated.
How to check that the angle micro switch is being fully actuated.
The micro switch can be found on the electrical panel located at the end of the square brass
section. The brass section is attached to the angle indicating mechanism.
To access the electrical panel, the rear cover must be removed.
When the bending beam is lifted this rotates the brass section which in turn depresses the
micro switch. You should be able to hear the micro switch click on and off.
Failing this, adjust the clutching force. This can be done by ensuring that the two M8 cap
head screws at either end of the actuator shaft are secured.
This adjustment should ensure that the actuator rotates and clutches however, if you are still
unable to hear the click, the micro switch may need adjusting.
The actuator can be adjusted by loosening the screw that secures it, making the adjustment,
followed by re-tightening the screw.
If the micro switch does not click on and off after you have made the above adjustments and
rotated the bending beam to the maximum stops, then the switch may be fused and would
need to be replaced. Call or email your distributor or Electrabrake.
Clamp bar not being released
This is caused by the failure of the reverse pulse de-magnetising circuit.
Check for sticky contacts on the relay and clean.
The 6.8 power resistor or diodes could faulty which will have to be replaced.
