Part # GLX-HAL-XSNUB
Hayward recommends installing a snubber on all ColorLogic 12v lighting applications, regardless of the controller and/or existence of GFCI circuits.
Symptom • An isolated transformer for low-voltage lighting is installed. • Turning the light(s) OFF or ON/OFF either via light switch or relay causes a GFCI breaker to trip, even on an unrelated circuit.
Cause • The inductive kick of an isolation transformer causes a brief arc across the switch contacts which injects arc noise into the supply wiring. This brief noise feeds back to the panel and to all the installed breakers. The circuitry inside the GFCI breaker may react to the arc noise and trip, even though there is no ground fault current present.
Approved Solution • Connection of a Hayward GLX-HAL-XSNUB snubber capacitor (arc suppressor) across the primary leads (line to neutral) of the transformer on the load side of the light switch or relay
A snubber is a plastic-film, high voltage capacitor that will suppress or “snub” the voltage spikes in electrical systems, such as the inductive kick from a transformer attached to a switch. Without arc suppression, these inductive spikes, though not harmful to users, increase the likelihood of nuisance trips in GFCI circuits but can also result in hiccups during Smart Relay light toggling on VS Omni applications.
The Snubber filters the high frequency noise that could otherwise throw the controller and lighting out-of-sync. The snubber will keep the ColorLogic Lights from falling out of sequence with each other. It can also resolve GFCI breakers tripping as a nuisance.
Hayward recommends adding the GLX-HAL-XSNUB snubber capacitor (arc suppressor) to non-Hayward transformers across the primary leads (line to neutral) of the transformer on the load side of the light switch or relay.
