Overview MIQ/CHV PLUS

6ba75539d03 03/2018

1.2 General characteristics

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 SENSOR NET system as

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 SENSOR NET.

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 SENSOR NET system

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:

MIQ/CHV PLUS Overview

ba75539d03 03/2018

Power supply When used in the IQ SENSOR NET, the valve module is supplied with voltage by

the IQ SENSOR NET.

IQ SENSOR NET

compatibility

The MIQ/CHV PLUS can be fully integrated in the IQ SENSOR NET using the

MIQ standard module housing.

The housing has the same characteristics as all MIQ modules regarding

stability, leakproofness and weather resistance. It also provides the same wide

variety of installation options (stacked mounting, canopy mounting, top hat rail

mounting, etc.).

Terminal strip The MIQ/CHV PLUS has the following electrical connections on the terminal

strip inside the housing:

1 x valve circuit connection

2 x SENSORNET connection

If the valve is controlled via an external switch, only one

SENSORNET connection can be used due to the limited number of

cable glands. SENSORNET connection 1 or 2 can be selected.

MIQ/CHV PLUS Safety instructions

ba75539d03 03/2018

2.2 Safe operation

2.2.1 Authorized use

The authorized use of the MIQ/CHV PLUS consists of providing a control valve

for compressed air-operated sensor cleaning heads in the IQ SENSOR NET. Only

the operation according to the instructions and technical specifications given in

this operating manual is authorized (see chapter 7 TECHNICAL DATA). Any other

use is considered unauthorized.

2.2.2 Requirements for safe operation

Note the following points for safe operation:

The product may only be operated according to the authorized use specified

above.

The product may only be operated under the environmental conditions men-

tioned in this operating manual.

The product may only be supplied with power by the energy sources men-

tioned in this operating manual.

The product may only be opened if this is explicitly described in this operating

manual (example: connecting electrical lines to the terminal strip).

2.2.3 Unauthorized use

The product must not be put into operation if:

it is visibly damaged (e.g. after being transported)

it was stored under adverse conditions for a lengthy period of time (storing

conditions, see chapter 7 TECHNICAL DATA).

2.3 User qualification

Target group The IQ SENSOR NET system was developed for online analysis. Some mainte-

nance activities, e.g. changing the membrane caps in D.O. sensors, require the

safe handling of chemicals. Thus, we assume that the maintenance personnel

is familiar with the necessary precautions to take when dealing with chemicals

as a result of their professional training and experience.

Special user

qualifications

The following installation activities may only be performed by a qualified electri-

cian:

Connection of the MIQ/CHV PLUS to the power supply.

Connection of external, line voltage-carrying circuits to relay contacts (see

module manual of the relay output module).
