463X Chlorine System Manual

Chlorine Sensor Preparation

2630 Free Chlorine Electrode 2632 Chlorine Dioxide Electrode

• Chlorine sensors are shipped without internal electrolyte solution.

• Prior to installation and supplying power, Chlorine sensors must be  lled with the appropriate internal electrolyte solution.

• Verify the correct electrolyte solution is utilized with the corresponding sensor.

• Free Chlorine and Chlorine Dioxide sensor require different electrolyte solutions.

Avoid skin or eye contact with electrolyte solution. Wear rubber gloves and goggles.

* Material Safety Data Sheets (MSDS) are available online at www.gfsignet.com.

Initial Fill Procedure:

When adding electrolyte, be prepared for an accidental spill. Working near a sink is recommended.

1. Remove the protective bottle from the end of the electrode

2. Remove the membrane cap from the front of the sensor.

Note: When new sensors are shipped, the membrane cap is not tightened to the sensor

3. Fill supplied syringe with electrolyte solution.

Additional caution should be taken when handling Chlorine Dioxide electrolyte solution.

4. Place the electrode on a level surface.

5. Insert syringe needle fully into one of the eight electrode holes while injecting with

electrolyte solution. Slowly injecting the electrolyte solution into the sensor to avoid introducing air bubbles. The electrode holds approximately 14 milliliters of solution. Slowly  ll until solution begins to  ow out of holes. Do not allow the solution to run down the electrode and wet the electrical contacts in the DryLoc connector.

6. Slowly screw on the membrane cap  nger tight. Do not use tools. To avoid damage

and contamination, do not touch the white membrane surface on the membrane cap.

Sensor Preparation

CAUTION:

DO NOT touch the gold tip or the membrane of the sensor.

Chlorine Sensor Calibration

A new chlorine electrode or one that has had the membrane cap changed must be calibrated. See page 24, 8630 Transmitter information on calibration of the chlorine sensor. A diethyl-p-phenylenediamine (DPD) colorimeter test kit (not included) is required for sensor calibration. A sample is taken and analyzed with the DPD test kit, then this value is entered into the Signet 8630 transmitter.

• Calibrate after a membrane cap change (requires 4 hour stabilization time).

• Calibrate after the internal electrolyte is replaced (requires 2 hour stabilization time).

• Check calibration one day after sensor is placed in service.

• Check calibration weekly to monthly depending on process requirements.

Chlorine Sensor Maintenance

The sensor membrane and internal electrolyte solution must be replaced over the life of the electrode. To maintain accurate chlorine measurements, GF Signet recommends that the internal electrolyte be replaced every 3 to 6 months, or when Chlorine readings drift low and/or cannot maintain a calibration longer than 5 days. Actual interval between maintenance of the sensor will be dependent on the actual applications, chlorine level and contaminates in the water. See Appendix page 36; Maintenance and Storage.

Keep spare membrane caps available. Membrane caps carry no warranty.

NOTE: Inspect and change the membrane cap if damaged. See page 36, Maintenance, for cleaning procedure.

11463X Chlorine System Manual

Sensor Installation

• Remove sensor access plugs from the  ow cell (pg. 4, Figure 1).

Note: Chlorine Sensor Preparation must be completed prior to installation, see page 11.

• Holding the 3-2750-7 (159 001 671) or 3-2650-7 (159 001 670) electronics inverted, open the DryLoc turning the upper locking ring ¼-turn counter-clockwise.

• Insert the electrode facing up. Turn the locking ring ¼-turn clockwise to lock the electronics in place.

• The mechanism will “click” when it is locked.

• Install the complete assembly into the  ow cell and ensure the key on the electrode aligns with the key slot on the  ow cell.

Avoid skin or eye contact with electrolyte solution. Wear rubber gloves and goggles.

Material Safety Data Sheets (MSDS) are available online at www.gfsignet.com.
