CAUTION

INSTALLATION

1. Refer to Figure 1 for dimensions of the mounting plate and the positions and

diameter of the mounting holes.

2. Remove the bag containing the diffuser plate from the flow cell. Place the dif-

fuser plate flat in the bottom of the flow cell. See Figure 2. Do not install the

sensor yet.

3. Connect the sample and drain lines to the flow cell. Process connections

are ¼ inch FNPT.

The flow cell must drain immediately to open atmosphere. Do not use

a long or convoluted drain line.

SENSOR/PROCESS APPLICATION COMPATIBILITY

ATEX DIRECTIVE

Special Conditions for safe use

1. All pH/ORP sensors have a plastic enclosure which must only be cleaned with

a damp cloth to avoid the danger due to a build up of an electrostatic charge.

2. All pH/ORP sensor Models are intended to be in contact with the process fluid

and may not meet the 500V r.m.s. a.c. test to earth. This must be taken into

consideration at installation.

MODEL 3200 HP INSTALLATION PUTTING THE 3200HP SENSOR IN SERVICE 1. Wire the cable to the analyzer. See the wiring diagrams in the wiring section. 2. Start the sample flow to fill the flow cell with water. 3. Unscrew the clear plastic nut on the flow cell and slip the nut over the sensor. See Figure 2. Remove the vinyl cap from the end of the sensor and place the sensor in the water in the flow cell. CAUTION WARNING The solution in the protective cap may cause skin or eye irritation. 4. 5. 6. 7. 8.

MODEL 3200 HP WIRING WIRING The 3200HP sensor is available with Variopol (VP) quick disconnect cable only. Although earlier versions of the sensor were supplied with a VP6 cable, current versions use a VP8 cable. The wiring diagrams in the manual are for VP8 cable only. If you have a VP6 cable, refer to the wiring diagrams on our website, www.raihome.com. The table below gives part numbers for VP6 and VP8 cable: Cable length VP6 VP8 10 ft. (3.0 m) 20 ft. (6.1 m) 30 ft. (9.

MODEL 3200 HP Do not connect the blue wire or the clear inner drain wire. Tape off each wire separately or cap with a wire nut to prevent spurious connections. Use a wire jumper to connect the solution ground terminal to the reference terminal. FIGURE 10 Xmt-P (panel mount) VP Wiring Do not connect the blue wire or the clear inner drain wire. Tape off each wire separately or cap with a wire nut to prevent spurious connections.

MODEL 3200 HP CALIBRATION 1. Select two stable buffer solutions. Ideally, the calibration buffers should bracket the expected pH of the sample and be at least two pH units apart. Use the ring at the bottom of the back plate to hold the beaker containing the buffer. 2. Most pH meters offer automatic buffer recognition. Automatic buffer recognition means the instrument automatically calibrates using the correct pH for the buffer temperature.

MODEL 3200 HP REPLACING THE CAPILLARY DISC (PN 34142-00) The reference capillary is protected by two filters, one on the inside of the disc and the other on the sample side. During normal operation, suspended solids in the sample coat the filter and hinder flow through the capillary. Occasionally, bacterial or fungal growth in the electrolyte solution will coat the inside filter. Eventually, as the coating builds up, the electrolyte flow becomes too low and the capillary disc must be replaced.

MODEL 3200 HP TROUBLESHOOTING TROUBLESHOOTING Problem Cause Solution pH reading is in error Electrolyte flow is too low – bubbles are blocking flow or the inside membrane on the capillary disc is fouled with biological growth. 1. Remove air bubbles. Follow the procedure in step 8 of the Putting the Sensor in Service section. 2. Discard the fill solution in the reservoir and sensor. Rinse the reservoir and sensor with fresh fill solution. Replace with fresh solution. Replace reservoir filter.
