IQ S MIQ/CHV Overview ENSOR Terminal strip The MIQ/CHV has the following electrical connections on the terminal strip inside the housing: l 1 x valve circuit connection l 2 x SENSORNET connection Note Due to the limited number of cable glands, only one SENSORNET con- nection can be used.
Safety instructions This operating manual contains special instructions that must be followed during the installation of the MIQ/CHV valve module. Thus, it is essential for the operator to read this component operating manual before carrying out any work with the system. Always keep the operating manual in the vicinity of the valve module.
6 T ECHNICAL DATA Safe operation If safe operation is no longer possible, the MIQ/CHV must be taken out of operation and secured against inadvertent operation. Safe operation is no longer possible if the MIQ/CHV: l has been damaged in transport...
Mounting for other applications Note This section is important if you want to operate the MIQ/CHV in connec- tion with conventional measurement converters or some other control unit. For details of mounting in the IQ S , see section 3.2.

Installation IQ S MIQ/CHV ENSOR 3.4.5 Mounting under the SD/K 170 sun shield If a single module is to be installed outside, it must be provided with a sun shield that protects it against the effects of weather. The SD/K 170 sun shield can be mounted directly on a wall, on a mounting stand or on a railing.
IQ S MIQ/CHV Installation ENSOR Position the module on the sun shield and fix it into place with the two screws (pos. 2 in Fig. 3-11). Close the module lid and fix it in place with the two countersunk screws (pos. 1 in Fig. 3-11).

Maintenance and cleaning ENSOR Maintenance and cleaning Maintenance The MIQ/CHV requires no special maintenance. Cleaning MIQ modules Clean the worst of any dirt off modules that are mounted outside as re- quired. To avoid any coarse dirt getting into the open housing, it is ad- visable to always roughly clean the module and the surrounding area before the module is opened.
