The motor drive outputs are protected by a self-resetting thermal cutout.

This provides protection against short circuits and also protects motors

from burnout due to stalling by external force or overloading.

When a short circuit or overload occurs on an output channel the output on

all channels will be greatly reduced and the main (red) power LED will be

dimmed significantly. After a few seconds the thermal cutout will be

activated on the short-circuit channel and the remaining channels will

return to normal operation. The cut-out time will vary depending on the

output settings of the controller but, provided that external wiring

conforms to the standard recommended by DHA Lighting, there will be no

immediate damage to either the DC controller or any DHA moving effects

connected.

While the fault persists the affected channel will remain in shutdown. The

controller should not be left in this state for any prolonged period.

The DC controller should recover in a matter of seconds once the source of

the fault is removed.
