Trips are divided into 3 categories for auto-reset, depending on the risk to the soft starter:GroupACurrent imbalancePhase lossPower lossFrequencyBUndercurrentInstantaneous overcurrentInput A tripCMotor overloadMotor thermistorHeat overtemperatureTable 8.1 Trip Categories for Auto-resetOther trips cannot be automatically reset.This function is ideal for remote installations using 2-wirecontrol in auto-on mode. If the 2-wire start signal ispresent after an auto-reset, the soft starter restarts.6-1 Auto-Reset ActionOption: Function:Selects which trips can be auto-reset.Do not Auto-Reset*Reset group AReset group A & BReset group A, B & CParameter Descriptions VLT® Soft Starter MCD 50066 Danfoss A/S © 05/2016 All rights reserved.
