Safety
| Temperature control | 2 Pt100 sensors Class A in 4-wire-circuit, mutually monitoring and taking over the performance at the same temperature value |
|---|---|
| Temperature control | mechanical temperature limiter TB protection class 1 switching the heating off at approx. 30°C above max. temperature of the bath |
| Temperature control | independently working, electronic overtemperature controller TWW protection class 3.1 or overtemperature limiter TWB protection class 2, adjustable in set-up menu by customer |
| Temperature control | in case of overtemperature due to failure, the heating is switched off at approx. 10°C above the set temperature (fixed value) |
| Autodiagnostic system | fuzzy-supported PID microprocessor controller with integrated autodiagnostic system with fault indication |
| Alarm | visual and acoustic alarm at programme end and as input acknowledgement as well as in case of low liquid level, heating is switched off automatically |
