Temperature High/Low Limit Control:
A user-programmable limit is provided by the Watlow F4 alarms. Alarm 1 is setup for
use with the product thermocouple (input 3). When the limit is tripped the safety valves
and contactors power down to prevent additional temperature changes.
Vibration High Limit Control:
A user-programmable limit is provided by the Watlow F4 alarms. Alarm 2 is setup for
use with the vibration signal (input 2). When the limit is tripped the safety valves power
down and bring the vibration to a halt.
Secondary High Limit Control:
In addition to the user-programmable Hi/Lo limit control there is a Watlow series 97
(Older) or PM EZ-Zone Limit (New). It is a secondary adjustable control is provided to
protect the chamber from high temperature damage. This device senses air
temperature near the electric heat elements in the plenum area and will shut down the
system if plenum temperatures exceed safe limits due to causes such as airflow
obstruction or failure, heat controller failure, or excessive product loading with
insu
ffi cient cooling (such as occurs when running out of LN2).
This secondary limit can be reset by pressing the reset button located on the controller.
