Issues

Pan motors seizing/binding/unable to operate correctly 

Possible Causes

A bug found in software version 1.2.7 presents the opportunity for damage to the pan motor if the fixture continuously pans & tilt for an extended period of time (30 minutes or more). V.1.2.7 should no longer be used. 

Other causes could be a faulty motor, a faulty pan/Tilt 2U PCB, faulty harness or damage to the motor by an external force

Solutions

If related to software bug in V.1.2.7- Update software using a HES Special Uploader and Replacement of Pan Motor if damage occurred 

If related to faulty component- Begin by replacing one component at a time with a working part to narrow down what component is failing
