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.)
