Why can't I calibrate my Chemtrol PC3000 Controller?
If you are unable to calibrate your Chemtrol Controller, check the water balance and adjust if needed. Clean the sensor, and check the sensor connections. If problems persist, test the sensor and electronics using the PORTAPROBETM.
How to fix a Chemtrol Controller with no display?
If your Chemtrol Controller display is not showing anything, begin by checking the power supply to the system. Ensure that the On/Off Switch on the right side of the cabinet is in the correct position. Verify that the Voltage Selector Switch in the upper section of the Power Board is set to the proper input voltage (110V or 230V). Lastly, check Fuse F2 on the Power Board and replace it with an AGC1 fast blow fuse if it's blown.
Why is my Chemtrol PC3000 causing chlorine or pH overfeed?
If you are experiencing chlorine or pH overfeed with your Chemtrol Controller, you should clean and test the sensor. Also, check and adjust the calibration and setpoint. Further, check the relay, the chemical feeder for leaks, and the Superchlorination Program. Finally, you may need to reduce the feed rate or dilute the solution.
How to adjust the contrast on a Chemtrol Controller display?
If the display on your Chemtrol Controller is faint or dark, adjust the contrast using the Display Potentiometer R39, which is located in the center of the Mother Board.
What to do if my Chemtrol Controller is showing improper readings?
If your Chemtrol Controller is displaying improper readings, begin by cleaning the faulty sensor. If the issue persists, test the sensor and the electronics using the PORTAPROBETM.
How to fix an erratic display on a Chemtrol PC3000 Controller?
If your Chemtrol Controller display is erratic, try turning the power switch off for 10 seconds and then back on. Also, check the power cable contacts and the power strip connecting the Mother Board and Power Board. Finally, press the program and memory chips on the Mother Board to ensure they have proper contact.
What to do if Chemtrol Controller has no chemical feed, heater activation, or valve activation?
If your Chemtrol Controller is not activating chemical feed, heater, or valves, first check the flashing line on the Main Display Screen. Use the UP or DOWN arrow to highlight it, then press the RIGHT arrow to enter the submenu and inspect the flashing line there. Possible causes include a LOW or HIGH ALARM flashing, in which case you should manually adjust the water chemistry or press the RIGHT arrow to change alarm limits, and consider setting Feed Lockout to Off. Alternatively, if the TIME LIMIT line is flashing, increase the chemical feeder rate, increase the Limit Timer setting, or reset the Time Limit with the AUTO setting. If the BYPASS LINE is flashing on the Main Display, check water flow and the Safety Flow Switch in the bypass line, or set Bypass Line to Off in the Operations Su...
