11.8 Availability of Physiological Alarms for External Devices
No physiological alarms are provided for external devices.
11.9 Essential Performance Characteristics
The HCU 40's safety system monitors the temperature regulation. When a water
temperature of 42.0 ± 0.5°C is attained, the safety system switches off the pump
and heaters of the machine immediately, and a high-priority visual and acoustic
alarm is triggered. The pump can only be switched back on again once the water
temperature has fallen below 41.0°C.
Temperature overshoots can be a maximum of 0.5°C (± 0.5°C measuring
accuracy) above 41.0°C for 10 seconds. When this limit is exceeded, the heater
switches off immediately, and a high-priority alarm is emitted optically and
acoustically.
A water temperature of 42.0 ± 0.5°C can occur in a type 1 error situation for a
maximum of 60 seconds.
