The over-temperature controller is an independent controller with an independent
thermocouple. When an over-temperature is reached, an alarm is signaled and the
electrical current is interrupted from the power controller to the heating elements. This
protects against a runaway temperature controller or malfunctioning power controller.
In the event of shutdown, the operator will have to manually reset the controller after the
over-temperature condition is cleared.
NOTE: All new systems require the high limit to be set before the rst
initial run. It will be necessary to press the manual reset button to
activate the system when power is turned on.
