463X Chlorine Systems Manual
Electrode Range:
The electrodes must match the type and range of chlorine concentration to be measured.
Flow Rate:
The electrodes must have a stable and constant
fl
ow of water past its membrane for accurate measurement.
When the sensor is installed in the Flow Cell Block 3-4630.392 (159 001 690), the
fl
ow rate range is controlled by the internal
fl
ow regulator and the
fl
ow rate is reduced to 30.24 to 45.36 LPH (8 to 12 US gph).
Sensor Conditioning:
A new chlorine electrode requires conditioning of up to 4 hours with the electrode powered on and
chlorinated water
fl
owing across the membrane to generate a stable reading. Subsequent start-ups can require an electrode
conditioning of up to 2 hours.
The maximum allowable operating pressure must be
less than 1 bar (15 psi). Higher pressures will damage
the electrodes.
The electrodes should not be used in water containing
surfactants, oils, organic chlorine or stabilizers such as
cyanuric acid.
CAUTION!
1 Follow instructions carefully to avoid personal injury or damage to electrode.
2. Prior to installation or removal:
a. Disconnect
fl
ow through system.
b. Drain below sensor level.
3. Con
fi
rm chemical compatibility before use.
4. Do not alter product construction.
These electrodes require the Signet 2650 Amperometric Electronics module to communicate with the Signet 8630-3P
Chlorine Transmitter.
