Watlow Electric Series 97 - Manual

S E R I E S 9 7
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.
