Nuisance tripping, especially in new installations, often means you are on the edge of the torque setting you need for your machine.  Increasing the torque setting of the H-TLC may be all that is needed to correct the nuisance tripping.  Since the H-TLC is externally adjustable, tightening the torque adjustment screws will increase the torque setting.  If you cannot get enough torque increase from the torque adjustment screws, you may need to consider going to the next larger spring set.  Please see the H-TLC Assembly and Spring Change Instructions in the “Downloads” section of our website.
Other items to review if you are experiencing nuisance tripping are:
Make sure the H-TLC is fully reset before restarting the machine.  If the H-TLC is not fully reset into its detented position, inertia of the machine may keep it from resetting upon start-up.  It is always recommended to jog the motor forward or reverse (either direction is fine) to get the H-TLC to reset, or else manually counter-rotate both ends of the H-TLC relative to each other until reset.  You should hear an audible “click” when the unit resets into its detented position.
Soft-start the motor.  If starting torque is causing the nuisance tripping, then using a soft-start on the motor will gradually accelerate the machine and lessen the amount of starting torque seen by the H-TLC, potentially resolving the nuisance tripping.
Nuisance tripping after extended use may indicate either the springs need replacement, or the housing is potentially worn from excessive tripping.
