a minimum of two feet of cable at the sensor lug end
being exposed to the same temperature as the sensor
lug.

Operation
When power is applied, the high limit relay will energize
into the normally closed position. If the high limit set point
is exceeded then the relay will de-energize opening the
circuit. The high limit relay can only be reset when the
temperature has dropped below the set point and the
manual reset button (on the front label) is depressed. The
high limit has a visual alarm LED, which is located in the
upper right corner.
Fault Indication: When the LED is “on”, the unit is
latched and in a safe condition (relay open). It can only
be reset when the fault condition is cleared.
Fault Conditions: Over temperature compared to
set point, open or shorted sensor, or any on-board
component failure.
