English term or phrase: fail-off
If the programmable controller is of conservative design and incorporates internal failure detection with fail-off action - including a proven reliable watchdog timer - then the programmable controller can imitate the failure mode of a relay system, reducing troubleshooting difficulty and false trips.

sensor de cortocircuito
Explanation:
The most common malfunction in solid state dimmers is a failed thyristor (triac or SCR). They can
either "fail on", in which the light cannot be turned off, of "fail off", in which the light cannot be turned
on. A "failed off" condition also may cause a resistor on the circuit board to burn. This failure is
almost always caused by a short in the load it controls. The short can be in the cable, in the
connectors, in the light fixture, or in the bulb itself. Although the dimmer circuit breaker or fuse will
open, it may not be fast enough to save the thyristor and the thyristor will need to be replaced.
Please check the load: plug it into a known good wall outlet before plugging it into other dimming
channels. Caution, a short in the load may trip a building breaker.
