Set Select
These contacts (4, 5) permit the activation
of a Set Contact relay when the measured
value is lower (connected terminals) or
higher (open terminals) than the user's set
value. See also page 25.
•
Recorder Output
(terminals 1, 2, 3)
These contacts are used for connection to a
recorder output. The output can be 0-20 mA
or 4-20 mA depending on the model and is
proportional to the measured conductivity
values.
Connect the “+” wire from the recorder to terminal 1 on the instru-
ment and the other wire (common) to terminal 2 for 4-20 mA re-
corder output or terminal 3 for 0-20 mA recorder output.
Note:
Only one recorder output connection is permited. In order to avoid
damages leave unconnected the unused terminal.
•
Alarm Contacts
(terminals 5, 6)
During normal operation these termi-
nals remain closed.
If the measured conductivity level is not
within the tolerance of the set value, the
alarm contact is open. These contacts act
only as a switch. See also page 26.
