TROUBLESHOOTING

General Troubleshooting Guide (also see Help Guide on page 47)
1.
Run Meter Self-Test (see Configuration menu)
2. Run Probe-Open Test (see Configuration menu)
3. Clear pH and ORP Tweaks (see Configuration menu)
4. Clean Sensors (see Maintenance section)
5. Check chemicals and feed system
6. Take sample of pool water for analysis of CYA, alkalinity, check saturation
index, Balance water
7. Replace Sensors
8. Repeat above steps
General Guidelines
This may be a common issue that can easily be resolved by increasing the amount of
chemical dispensed each day. If the pH Sensitivity is set to "Low" (the default), IntelliChem
will only administer the full dose at 0.5 from setpoint. If it seems to be stuck 0.3 from
setpoint, you're only getting 3/5 of the programmed dose. Change the Sensitivity to "High"
and you'll get the full dose at 0.2 pH or greater from setpoint. Or, turn pH Sensitivity OFF -
only turn it on if you're overshooting the setpoint.
Increasing the dose would essentially do the same thing. Increase the dosage as well as
the dose-limit and reduce the mix time so you still get all 8 doses in the filter run time.
Diagnostics Self Test and Error codes
The overall functionality of the IntelliChem can be verified by running the self test. Access
this feature in the Configuration/Diagnostic menu. The test verify the LCD display, front
panel LED indicators, push buttons, flow switch input, doser motors, relays, the RS-485
communication, and the meter.
Warning! This test will turn on the doser, so be sure that the tubing is installed in a
safe manner so that the chemicals will be safely contained.

INTELLICHEM Controller Installation and User's Guide
®
Controller with SunTouch Control System
®
Displays the current pH and ORP levels. The IntelliChem
controller is connected to the SunTouch control system
via the RS-485 cable. The RS-485 communication cable
is connected to the COM port on the SunTouch
System circuit board.
