Under a sensor alarm, we understand the case, where
a) the sensor wire is squeezed somewhere in between sen-
sor and controller and a short circuit exists
b) the sensor is not in the intended position (removed or is
swapped with another).
How it works Through the defect in the cable to the controller a low tem-
perature value is forecast. The actual temperature is much
higher than the measured temperature.
If there is no rise in temperature measured in a zone type
(considered nozzles and manifold) in a dependent time, a
sensor alarm is displayed to the user. To prevent damage
to the appropriate zone, the heating is turned OFF.
A sensor alarm can be faulty, and that is when the heat out-
put of the zone is too small. It shows an identical error im-
age.
What good is it The sensor alarm provides the user with a specific indica-
tion of the error in the hot runner or the wiring, and provides
the ability to pinpoint errors quickly and correct it.

On the sensor input a too high voltage is detected.
How it works Error is detected by the hardware on the HTC 06/15 Heating
Thermocouple Card.
What good is it For protection all zones get de-energized (relay on HTC-
Card OFF), also the zones on the other HTC-Cards, due to
the voltage may come from any zone.
