Troubleshooting
Problem:
The IntelliChlor 100% light does NOT come on when the ORP controller calls for chlorine
Actions:
1. Verify the ORP controller is opening and closing the dry-contact output.
2. Remove the ORP CONTROLLER wires connection from the power center and the ORP controller.
Manually tie the ORP CONTROLLER wires together. This will turn on the cells at 100%. If the 100%
lights do not come on, verify the communication wires are connected.
Problem:
The IntelliChlor 100% light stays on after the chlorine controller says to stop
Actions:
1. Verify the ORP SENSOR wires are not shorted together in the power center.
2. Verify the ORP controller dry contact output is opening and closing by using an ohmmeter. Manually
set this output open and closed using the controller menu system.
More and Less Output Buttons on Intellichlor cell.
These buttons control the output setting and only operate in a single-cell system where the cell is
connected to the standard 520556 power center, no ORP. When an ORP system is used, these buttons
are disabled. Chlorine demand is controlled by the ORP controller.
Note: For best flow sensing,
provide at least 12 - 18
inches of straight pipe in front
of the CELL INLET
