the controller back to factory default conditions so it is recommended that all motor and I/O cables be removed for
safety while performing the Master Reset. Cables can be plugged back in after the correct settings have been
loaded back to the controller (when necessary). To perform a Master Reset - find the jumper location labeled MR
or MRST on the controller and put a jumper across the two pins. Power up with the jumper installed. The Self-Test
will take slightly longer - up to 5seconds. After the error light shuts off, it is safe to power down and remove the
Master Reset jumper. If performing a Master Reset does not get rid of the error light, the controller may need to
be sent back to the factory to be repaired. Contact Galil for more information.
