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.

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 ﬁ ll until solution begins to ﬂ 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 ﬁ nger tight. Do not use tools.

To avoid damage and contamination, do not touch the white membrane surface on

the membrane cap.

The Signet Amperometric Chlorine Electrodes are designed to measure chlorine in fresh, clean water treatment applications.

Free Chlorine electrodes are available in measurement ranges of 0 to 2 ppm, 0 to 5 ppm or 0 to 20 ppm.

Chlorine Dioxide electrodes are available in measurement ranges of 0 to 2 ppm.

Electrodes require the Signet 2650 Amperometric Electronics to output a digital (S

L) signal to the Signet 8630 Chlorine Transmitter

Features:

• Utilizing smart-sensor technology, this electrode incorporates a unique embedded memory chip within the electrode to

communicate a wide variety of information to the Signet 2650 electronics and Signet 8630 transmitter. Electrode type,

factory calibration data, service time, chlorine range, high and low pH (with optional Signet pH electrode), temperature limits

and more are stored on the chip. This information is accessible via the Signet 8630 transmitter.

• Signet's patented DryLoc

connector provides quick assembly and a secure connection. Gold-plated contacts and an O-ring

seal ensure a waterproof and reliable interconnect to the Signet 2650 Amperometric Electronics.

• Integrated temperature element for automatic temperature compensation.

• Separate drive electronics (Signet 2650) allow easy electrode replacement without running new cable.

*3-2630.090*

• Chlorine sensors are shipped without internal electrolyte solution.

• Prior to installation and supplying power, Chlorine sensors must be ﬁ 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.

CAUTION:

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

3. Operation Electrode Range: The electrode must match the type and range of chlorine concentration to be measured. Part Number Chlorine Range 3-2630-1 0 to 2 ppm (mg/L) 3-2630-2 0 to 5 ppm (mg/L) 3-2630-3 0 to 20 ppm (mg/L) 3-2632-1 0 to 2 ppm (mg/L) Chlorine Dioxide Flow Rate: The electrode must have a stable and constant flow of water past its membrane for accurate measurement. When the sensor is installed in the Tee flow cell 3-3610-2 (159 001 684), the flow rate must range from 37.8 to 75.

6. Storage and Disposal Store electrode between –10 ºC to 60 ºC (–14 ºF to 140 ºF) at a relative humidity that does not exceed 95%. The primary concerns when storing the electrode is membrane dehydration and freezing in extremely cold environments. DO NOT FREEZE 6.1. Storage of the Sensor If the sensor or panel assembly is to be removed from service for a period of time the sensor must be properly prepared for storage and may need to be recommissioned.

6.1. Storage of the Sensor continued Reconditioning Procedure Continued: (Steps 1-10, See Previous Page) 11. Fill beaker with a 12 mm (½ inch) of the appropriate solution. 12. Position or suspend the sensor 0.2 mm to 12 mm (¼ in. to ½ in.) above the appropriate Figure 2 solution. DO NOT SUBMERGE THE SENSOR. See Figure 2. 13. Apply power to the system. 14. Monitor the nA of the sensor (press the down arrow once on the 8630 transmitter). The nA reading should start to rise.

8. Mounting Position continued Mount the flow cell where the sensor will be easily accessible. To avoid air bubble entrapment, do not mount with downward flow. Flow NO 9. Overview Chlorine in Water Various forms of chlorine are used to disinfect water. Each form of chlorine has benefits and limitations which help determine the specific application. The predominant categories used in disinfection are Free Chlorine, Total Chlorine and Chlorine Dioxide.
