Connecting A Sensor - Endress+Hauser Liquiline To Go Ex CYM291 Operating Instructions Manual

Start-Up

Connecting a Sensor

The Liquiline To Go Ex CYM291 provides several connections so that many types of
sensors can be used for measurement (see illustration below). Note that only one
sensor may be connected to the meter at a time. The meter recognizes the connect-
ed Memosens sensor and displays the Memosens logo.
Separate temperature probe
After power-on, a separate temperature probe is automatically recognized. When
you want to replace the temperature probe, you must switch off the meter and then
switch it on again.
WARNING!
When using sensors without explosion protection approval, the Ex
approval of the Liquiline To Go Ex CYM291 will be invalidated. Therefore,
use the device only with sensors which have an appropriate Ex approval.
a
Memosens sensors have a cable coupling, which allows convenient replacement
of sensors while the cable remains connected to the meter. The connecting cable is
connected to socket b (M8, 4 pins) or e (M12, 8 pins).
