Description
A cooling system (RKA) is responsible for cooling the water and the (non) conduc-
tivity in the de-ionized water cooling circuit of a water-cooled power unit. The cool-
ing system is controlled and monitored from a PLC that is part of the cooling sys-
tem. The cooling system function module described here is used as an interface
between the closed-loop control and the external control (open-loop) (PLC) of the
cooling system. The cooling system is controlled via terminals (e.g. Control Unit,
TM31).
