TEMPERATURE LIMIT(S)
Adjust the set point(s) of the temperature limit(s) down to a point lower than the PV (process
variable is typically the current fluid temperature at the heater outlet). Solid-state controls will
deactivate a control relay powering a set of n.c. contacts in the interlock circuit. Analogue controls
will open their contacts in the interlock circuit. The trip temperature should be within 5 degrees of
the PV temperature. Reset temperature limit if reset exists.
