Type of Problem Possible Cause or Solution be corroded or diaphragm could be defective. 4. Make sure wiring from controller to pressure switch are shielded wires. Also route wire away from any AC lines or motor windings. 5. Inlet to pressure switch is obstructed. 3. Motor starter trips repeatedly. 1. Verify wiring to and from coil and controller. 4. Controller display shows “System On” but system does not run. 5. RO Controller shuts off, does not restart, and no alarm indication is present. 6. RO Controller shuts down on high temperature even though the temperature is below setpoint. 2. Verify that the overload relay is set according to rating specified on motor nameplate. 3. Check the secondary voltage on the transformer (should be 24 VAC ± 2 volts). 1. Verify wiring. 2. Check motor starter for overload. 3. Controller is in Tank Mode and tank is full. 4. Controller is in Stand-By Mode and system is between auto flush cycles. 1. Possible brown out, or power outage reset the controller to “System Off”. 1. Calibrate temperature sensor. 2. Check sensor wiring. 5-1 5-2
Type of Problem Possible Cause or Solution 9. Conductivity monitor shows reading to be higher than known solution. 10. Conductivity monitor does not respond to known solution. 11. Conductivity monitor shows low reading for known conductivity changes. 1. Check calibration of each cell. 2. Sensor electrode not fully immersed. 3. Air bubbles in sensing area. 4. Fouled sensor. 5. Defective sensor wiring. 6. Relocate sensor. 7. Clean sensor electrode. 8. Check sensor wiring. 1. Calibrate sensors. 2. Check/replace sensors. 3. Check/replace leads to sensors. 1. Sensor electrode obstructed. 2. Inadequate solution circulation. 3. Clean or relocate sensor. 12. Conductivity reading is erratic. 1. Faulty sensor. 2. Faulty sensor wiring. 3. Moisture in cables. 5-3
