4.3 Safety function
Technical safety functions protect the device from damage. The safety functions
are not affected by the control circuit. If a safety function trips, all actuators are
permanently switched off. The operator is warned by an optical and acoustic
alarm on the circulator.
High pressure switch
A pressure switch trips when the condensing pressure reaches a defined value.
The device switches off the pump, heater and cooling machine. A continuous
signal tone sounds. A warning message appears on the display of the connected
circulator. The cause must be determined and rectified.
Intrinsically safe devices do not have a high pressure switch.
