Control and operating unit
The control and operating unit controls the water circuits and the refrigeration circuit. The control
and operating unit with display of the water temperature as well as the error codes in the case of a
general fault alarm is integrated in the control cabinet door.
2.7 Electrical/Control Equipment
The electro-technical equipment of the P030 Chiller is installed in the control cabinet. All required
components for the automatic switching, controlling and regulating operation are contained in the
control cabinet.
The main electric circuits are of a non-fused design featuring motor protecting switches.
The water outlet temperature is kept constant by the control and operating unit at a given setpoint
value by activation of power stages in the refrigeration circuit. The current water outlet temperature
is displayed on the control and operating unit.
The connection of the P030 Chiller to the equipment to be cooled is effected via a potential-free
interface. To achieve a galvanic isolation of the equipment to be cooled and the P030 Chiller, the
connection is accomplished by means of optical-fibre cables.
