3-10 Installation and wiring
3-7. Wiring other galvanic sensors
Consult the users manual for the color identification of the sensor cable and connect temperature com-
pensator, cathode and anode to the terminals: 11, 12, 13 and 15 as described above.
Connect the cable shield to 14 if there is one available. Sensor diagnostics is normally not possible.
Note:
A jumper cable is placed to connect converter terminals 13 and 17.
Make sure that connecting the sensor cable to the IE pin or pin 13 or pulling the sensor cable
does not cause the jumper cable to come loose. Insufficient tightening may cause unstable or
false measurements.
3-8. Wiring the standard optical sensor (DO70G)
Note:
A jumper cable is placed to connect converter terminals 13 and 17.
When a standard optical sensor (DO70G) is to be connected, the cable is not used, so disconnect
it. It is recommended to save the jumper cable for future use—if may be needed when a galvanic
sensor is used.
The color of the wiring of the sensor cable supports the indication of each terminal.
