As manufacturers are required to meet tighter safety

standards, Watlow has addressed this need with its new

SERIES LS safety limit. This new limit meets UL® 1998

and EN 60730 safety requirements and will shut down

a system to prevent damage to equipment or injury to

personnel.

Watlow’s SERIES LS is recommended for any application

where control failure could cause the temperature of

the application to continue to increase resulting in large

product scrap costs, damage to system equipment or

potential fire hazard.

The SERIES LS provides increased safety due to the use

of a factory fixed set point, factory fixed hysteresis and

the use of redundant temperature sensors to protect

against a single point sensor failure. Either sensor can

initiate an overtemperature limit condition along with a

deviation between sensors greater than the process

comparison value.

Watlow’s new SERIES LS offers fixed limit set point

temperature values that are customer definable in the

product configuration part number. It is available with

a potted module design configuration and push-on,

quick connect spade terminals to provide the electrical

connections.
