- Conductivity Sensor Head WL200
- I. WL200 Checklist
- II. Inspection
- a. Your WL200 unit was carefully inspected and certified by our Quality Assurance Team before shipping. If any damage has occurred during shipping, please notify Global Water Instrumentation, Inc. and file a claim with the carrier involved.
- b. Use the checklist to ensure that you have received everything needed to operate the WL200.
- III. Features
- a. Conductivity Switch
- 1. Sensitivity-adjustable controller
- 2. No moving parts
- 3. Safe operation
- 4. Controls up to two levels with controller
- 5. 1” NPT fitting (bulkhead or flange-type fitting available.)
- 6. One to three electrodes, depending upon tank material and number of functions required
- 7. Electrodes are 1/8” diameter, 316 Stainless Steel; all wetted material are food grade.
- 8. Standard 24” electrode can be cut by end user to shorten the length; two 24” extensions can be added for a maximum recommended length of 72”.
- 9. Option
- 10. Other
- b. R-Series Controller
- a. Conductivity Switch
- IV. Specifications
- V. Operation
- VI. Installation
- Warnings: Install controller according to applicable electrical codes.
- Unit must be installed using Global Water’s R2 Controller.
- Do not connect directly to line voltage.
- Not for use in hazardous (explosive) environments.
- Do not exceed pressure and temperature ratings.
- a. Conductivity Sensor Head / Conductivity Probes
- 1. 1 inch NPT (Standard)
- 2. Probes can be cut to length. Remove probes from sensor head by carefully unthreading them from inserts. Do not over tighten when reinstalling.
- 3. Cut two (2) probes to the same length, these will be the common and lower level probes. (See Figure 1, page 11.)
- 4. Cut one (1) probe to the desired length for the upper level of the tank. (See Figure 1, page 11.)
- 5. Spacer should be located approximately 1 inch from bottom of shortest probe.
- 6. If build up occurs on probes a short circuit could occur. If this happens, apply shrink tubing to the probes leaving the last one (1) inch bare.
- b. Wiring
- 1. Install cable into sensor head through the compression fitting supplied.
- 2. Attach one lead between the common probe terminal, and pin five (5) on the controller.
- 3. Attach a second lead between the lower level probe terminal, and pin six (6) on the controller.
- 4. Attach a third lead between the upper level probe terminal, and pin eight (8) on the controller.
- 5. Tighten compression fitting until cable can not be pushed into sensor head.
- c. R2 Conductivity Configuration:
- 1. 120 VAC is connected between pins 2 and 7
- 2. Wire the Common Probe to pin 5
- 3. Wire the Lower Probe to pin 6
- 4. Wire the Upper Probe to pin 8
- 5. Pins 1–3 and 1–4 are isolated switch contacts to switch power to a valve or pump.
- Note: For single level control, connect probe to pin 8 and use pin 5 as the return
- d. Typical Controller Hookup to Switches:
- 1. Set switches “Normally Open.”
- 2. Connect Upper switch to pins 6 and 8, Lower switch to pins 5 and 6.
- 3. Connect the switched voltage to terminal 1 (AC or DC Volts)
- 4. For Pump-Up: Connect one end of the pump/valve to terminal 4 and the other end to the switched voltage return
- 5. For Pump-Down: Connect one end of the pump/valve to terminal 3 and the other end to the switched voltage return.
- 6. Connect line voltage to terminals 2 and 7.
- e. Conductivity Probe Kit Add-On Electrode Installation:
- 1. Cut the add-on electrodes to the length needed for your application. De-burr the cut ends with a fine file or equal.
- 2. Insert the threaded end of each add-on electrode into a coupling, just to the end of the threads.
- 3. Secure the coupling to the electrode with one (1) of the supplied set screws.
- 4. Connect the add-on electrodes to the electrodes from the junction box by placing the couplings over the electrode ends until the ends of the add-on electrodes contact the junction box electrodes.
- 5. Secure the couplings to the electrodes with the rest of the supplied set screws.
- 6. Slide the plastic spacer from the kit over the ends of the extended electrodes. (See Figure 2, page 11.)
- VII. Maintenance
- VIII. Trouble Shooting
- a. Call us for tech support: 800-876-1172 or 916-638-3429 (many problems can be solved over the phone). Fax: 916-638-3270 or Email: [email protected]. Be prepared to describe the problem you are experiencing including specific details of the application and installation and any additional pertinent information.
- b. In the event that the equipment needs to be returned to the factory for any reason, please call to obtain an RMA# (Return Material authorization). Do not return items without an RMA# displayed on the outside of the package. Clean and decontaminate the WL200 if necessary. Include a written statement describing the problems. Send the package with shipping prepaid to our factory address. Insure your shipment, as the warranty does not cover damage incurred during transit.
- c. When calling for tech support, please have the following information ready:
