Electrical wiring connectors
eSelect-CD1 is provided with 2 multiple cable glands for various input and output cable wirings. Complying with International
electrical wiring rules., we advice not to connect more then one equipment on each pin.
CONNECTORS GLANDS USE:
Cable gland 1: Power cable
Cable gland 2 and 3: Recommended use for:
• Set-points relay outputs
•
mA output
•
Level probes for chemical tanks
•
12Vdc input
•
Flow sensor
• AUX output
• Conductivity sensor
• Temperature Sensor
Connecting conductivity sensor
eSelect-CD1 works with simple conductivity 2-electrode open sensors, with AISI 316 and Graphite electrodes.
NOTE FOR CONDUCTIVITY SENSORS
eSelect-CD1 works with simple conductivity 2-electrode open sensors, AISI 316 OR Graphite electrode.
FOR CONDUCTIVITY SENSORS with internal temperature sensor: due to the various types on the market, in case operator wished
to use such sensor, use PT100 temperature sensors, please contact ETATRON D.S. service or Local Dealer to get the right
configuration. eSelect-CD1 is NOT suitable for inductive EC sensors!
Install conductivity sensor into the system or an off-line holder and connect to Terminal board (see page 13) before connecting to
mains. We recommend using a new electrode or at least in good conditions (not old).
Connect Conductivity sensor to internal terminal board.
PLEASE NOTE:
eSelect-CD1 automatically adjust itself for various conductivity ranges by adapting the controller to the different probes cell constant
“K” characteristic. However, at the beginning of programming and in “Expert Menu Set-point1” user can adjust the required K factor.
It is always RECCOMENDED and mandatory to use the correct K probe according to the range in which the controller is working.
