Monitoring Coolant Temperature
If the temperature of the cooling water is too low, condensation will occur on the heat sinks depend-
ing on the humidity, which can lead to malfunctions and damage to the unit. To prevent this, the
cooling water flow temperature must not fall below 18°C. The coolant temperature is controlled by a
thermal sensor in the cooling water inlet, the measured temperature is shown on the display of the
PLC in the HTS cabinet
N O T I C E
To avoid condensation, the cooling water temperature must be at least 18 ° C.
Warnings
Warning messages are displayed in the main menu. In addition, all warning messages that have oc-
curred can be read out via the interface.
