4. An Over temperature Limit Controller With User Defined Messages Watlow s SERIES 97 is a microprocessor based controller with a single input second auxiliary input and four outputs Input one is used to measure temperature from a sensor Input two can be utilized as a remote reset switch or a hardware lockout switch With up to four outputs the controller is versatile in handling applications that require a high low limit alarms retransmit and communications The control is so user friendly that it can be set up to display safety and limit messages created by the end user to meet the exact application need The SERIES 97 limit controller is added to thermal applications to limit over temperature conditions The SERIES 97 limit controller provides safety assurance against instances where a high temperature runaway condition could occur from a shorted input sensor or an output device that could fail in a closed position The SERIES 97 is recommended for any application where thermal runaway could result in large product scrap costs affect operator safety cause damage to equipment or create a fire hazard The SERIES 97 is manufactured by ISO 9001 registered Watlow Winona and reliably backed up by a three year warranty 2003 Watlow Electric Manufacturing Company Features and Benefits Programmable messages e Controller can be set up to display user programmed limit message NEMA 4X IP65 e Water and corrosion re
