Humidification pump
The pump is driven by a three-phase motor powered by magnet controlled protective motor
switches. The control consists of a PLC-control system regulating the area humidity. The
regulation takes place by means of PI regulators to ensure a precise regulation of the area
humidity.
The PLC program is built up in such a way that you on the first start-up choose the number of
active sections. If e.g. three sections are chosen, section 4 is disconnected in safety circuits
and on display. On extensions, this choice can be repeated by using password 196.
In the control six hour meters are built in. One hour meter to indicate the operation time of
the pump to be used when determining the service intervals, one hour meter for the RO pump
and one hour meter for each of the four sections summarizing the humidification time.
