1. Introduction and 2. Safety information
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.
