General Characteristics - Xylem WTW MIQ/CHV PLUS Operating Manual

Overview
1.2
The MIQ/CHV PLUS valve module provides a switchable compressed air valve
for the operation of sensor cleaning heads.
The MIQ/CHV PLUS valve module registers on the IQ S
an output (V). It appears in the list of outputs and can be linked with a sensor.
Thus, the valve is controlled directly by the IQ S
Alternatively, you can also control the valve via an external switch. The switch
can consist of one of the following:
 any relay in the IQ S
 the relay of a measuring transmitter with the R option
 any other switch (relay or sensor)
The valve module is connected with the external switch via a control line for this.
The following application example shows a cleaning system consisting of the
CH cleaning head and a MIQ/CHV PLUS valve module:
