2.3Safety features

General cut-off

The heater, the compressor and the circulation pump can be switched off by a relay built into the unit. This general cut- off will be activated if a malfunction is detected by the safety sensors.

See 7.4, Description of Safety Features.

Protection against over-heating

A built-in temperature limit switch protects against uncon- trolled heating of the bath liquid by activating the general cut-off if this limit is exceeded.

The built-in temperature limit switch also senses low levels of coolant.

See 7.4, Description of Safety Features.

Pump motor protection

When the temperature in the winding of the pump motor reaches a certain level, the general cut-off will be activated, preventing the motor from overheating.

See 7.4, Description of Safety Features.

Sensor check

The temperature sensor is permanently monitored. The gene- ral cut-off is activated if sensor breakage or current leakage is detected.

See 7.4, Description of Safety Features.

Restart after power failure

MultiTemp III automatically restarts after a power failure. See 7.4, Description of Safety Features.
