2.3.4. Sensors

pH and ORP Sensor Wiring

DCM 200 controllers normally have the cables for the pH and ORP sensors pre-wired and marked on the cables for the

appropriate sensor. The SGT (Solution Ground+Temp) sensor and flow switch are also pre-wired at the factory. If

replacing these cables, connect the center pins on the coaxial cables to the positive [+] terminal and the metallic shield is

connected to negative [-]. A solution ground reference is required for proper operation. An SGT sensor has a solution

reference (Green or Black) and temperature sensor (White or Red). Even if the temperature sensor is not being used, the

solution reference must be connected to the ground terminal.
