Emergency Stop

At this input, you can connect the maximum thermostat usually integrated in the electric heater. This input provides an emergency stop in case of overheat.
If the maximum thermostat "EmergencyStop" detects overheat and opens its normally closed input, all stages will switch off immediately ignoring the blocking-off times.
After the overheat alarm returns to normal again, the control loop starts as a P controller. After a delay equal to the I-time, the integral part will be activated.
