463X Chlorine Systems Manual

CAUTION!

• Remove power before wiring.

• Follow instructions carefully to avoid personal injury or

damage to the electronics.

• Refer to the wiring diagram above to connect the 2650 cable to the terminals on the 8630 Chlorine Transmitter.
• For calibration and con

guration please refer to the 8630 Calibrate Menu discussions above.

The electronics are pre-wired from the factory to the transmitter. Refer to the following

schematics when replacing the electronics.

• The Signet 2650-7 Amperometric Electronics provide the polarization voltage and signal conditioning required by the Signet

2630-X and 2632-X Sensors.

• The Signet 2750-7 pH Electronics conditions and ampli

es the output from the Signet 2724-00 pH Electrode.

• Both units output a Digital (S

L) signal to the Signet 8630 Chlorine Transmitter.
