Section : 3 Sensor Mounting
3.1 General Guidelines
Select a location within the maximum sensor cable length (05 Mtr) for mounting of the sensor.
Sensor to be installed Inline to piping where the pipeline stay filled with the working fluid
(water) whether in operation or not. If there is more than 05 Mtr distance from the electrode
to the controller, purchase an offline sensor housing (available on demand) for measuring
conductivity or use an amplified conductivity sensor. Locate sensor away from pumps,
frequency drive systems or other sources of high frequency.
Refer to the installation manual of conductivity controller for sensor installation and
maintenance. RCB can provide industrial grade sensor KE-CDS 1000 series for industrial
standard applications which is recommended with KE-CD 1000 controller for efficient results
and little to no maintenance.
Section : 4 Controller Electrical Connections
4.1 General Guidelines
KE-CD 1000 controller requires a regulated 16 - 24 VDC connection from an external supply
(not provided) to work properly.
WARNING: Don’t connect AC power cables to the KE-CD 1000 controller.
Important Notes:
•All electrical installations must be supervised by a qualified and responsible electrician.
•Use wiring practices that conform to all national, international and local electrical codes.
•Don’t put sensor cables or instrument 4-20 mA output wires in the same conduit that
contains AC power wires. AC power wires require a separate conduit to prevent electrical
noise from interfering with the instrumentation signals.
4.2 Power
A 16 - 24 VDC power supply (max. 35 VDC) must be used to power the KE-CD 1000 controller.
The exact connection of this power supply is shown in the given image in this section. Always
separate input DC power from high power sources, frequency drives, motors, or other electrical
signal wires, which may contribute noise to a system and cause disturbance in reading.
KE- CD 1000 controller has the power polarity protection which means if +ve power supply is
connected to -ve connection of controller, it will not cause any malfunctioning of controller
however it will not power on the Controller. Make sure input DC power is stable, noise free and
non-fluctuating.

4.3 Sensor Electrode
The sensor electrode cable can be connected to the KE-CD 1000 controller terminal strip by
matching the wire colors on the cable conductors. Route the signal cable away from AC power
wires, frequency drives, motors, or other electrical signal wires. Do not put sensor or signal
cables in conduit that contains AC power cables and motor cables.
Note: Terminal blocks are labeled on Controller back part.
