9.8 Heating Current Monitoring
A monitoring of the heating current enables the secure and early identification of the following faults:
 Insulation damage and/or partial failures of heaters
 Total loss of a heater of a group connected in parallel e.g. at the hot-channel distribution column or at the extrusion tool.
 Failures of individual control zones,
 For example, through defective heater, triggered protection interrupt or defective power circuit-breaker.
 Shorts on the power circuit-breakers (solid-state relay, TRIAC's, relay, contactor)
The measurement of the heating currents is implemented in a fixed time raster. The error messages are calculated
after every measurement. For the avoidance of nuisance alarms through faulty measurements, the appropriate
measurement is repeated with identification of a fault immediately and repeatedly before an alarm signal of the
controller is output.
In this case the two following error types are distinguished between:
(a) Tolerance alarm (SAE-Alarm)
