3.4.4 Safety concept
WARNING
Risk of injury due to modified safety devices.
Non-functional, modified or defective safety devices lead to serious accidents.
• All modifications to the unit and especially the safety devices are prohibited.
• In case of defective safety devices, shut down the unit immediately and take it out of operation.
3.4.4.1 Safety devices
• The cooling units have a tested pressure switch in accordance with EN 12263. The pressure switch reacts to a pressure
increase in the refrigeration circuit by switching off automatically.
• The fans and compressors are protected against overloading and overheating. For example, the compressor is protected
against overspeeding.
• The cooling units are equipped with a motor circuit breaker which trips when the compressor is overloaded. The cooling
unit is switched off. The motor circuit breaker must be reset "by hand". When the motor circuit breaker trips, a serious
error can be assumed.
3.4.4.2 Additional protection function
Only cooling units with antifreeze option.
• The compressors and fans switch off if there is a danger of freezing.
• The unit must be restarted to exit this switch-off function.
