1. REMOTE EMERGENCY POWER OFF This isolated input is used to turn off the STS remotely in case of emergency The STS is supplied from the factory with the Remote Emergency Power Off R E P O terminals open circuited see View of the STS connections if two NO terminals are shorted to each other STS shutdown the output voltage In case of emergency by activating the stop device STS enters to stand by mode and powers off the load completely The R E P O circuit is self powered external power supply voltage is therefore required If R E P 0 switch pressed at least 1 second STS trips the signal E USE DESCRIPTION The purpose of the STS is to select one of two input power lines which is in tolerant with predefined limits Users must decide that one of the input sources must have priority preferred source the other source is alternate source So the STS tries to stay at priority preferred source if this source in tolerant with predefined values if this source out of tolerant and the alternate source is in tolerant STS transfers the load to alternate source Always STS checks priority preferred source if it is in tolerant retransfers the load to priority preferred source So before use the STS we must decide that which source is main preferred and which source is spare alternate IMPORTANT Our STS are designed and produced for long life even under severest conditions Remember howeve
