14 ABB ARC GUARD SYSTEM™ – TVOC-2—ConfigurationTrip condition configuration – Manual/auto reset configurationTrip condition configurationTVOC-2 can be configured to trip selected breakers depending on which detector is signalling for an arc. This can be used to trip sections of a switchgear or use one monitor for several small switchgears. It also has an option to add a current condi-tion, see page 13.Manual/auto reset configurationThe signal relays K2, K3 can be configurated to react as the trip contacts (auto reset) or to be de-energized by manual reset on the HMI. See below for explanation.System configuration using DIP switchDIP switches are used to configure the system regarding use of current condition (activated CSU inputs) and assigning detectors to breaker trip outputs (so-called selectivity). They are located on the front (low, left) of the Arc monitor.DIP switchesSw1Current condition inputs Terminals X1:21-22Sw5Not usedSw2Current condition output Terminal X1:23Sw6Autoreset K2, K3 (signal relays)Sw3Trip output assignSw7Not usedSw4Trip output assignSw8Not usedBreaker trip outputDetector inputsOutput relay K4Terminals X1:1-10Output relay K5Terminals X2:1-10Output relay K6Terminals X3:1-10
