How to troubleshoot ERR 2 on Autotrol Logix 760?
If the Autotrol Control Unit displays ERR 2, the controller power doesn't match 50 or 60 Hz. Disconnect and reconnect the power. If the problem persists, obtain the appropriate controller or AC adapter for either 50 or 60 Hz power.
Why is my Autotrol Control Unit leaking hard water after regeneration?
If you're experiencing hard water leakage after regeneration with your Autotrol Control Unit, it could be due to several reasons. First, the regeneration might be improper; repeat the regeneration after ensuring the correct regenerant dosage was set. Second, there might be leaking of the external bypass valve, so replace the bypass valve. Third, the O-ring around the riser pipe might be damaged, so replace the O-ring. Finally, the capacity might be incorrect; verify the appropriate regenerant amount and system capacity.
Why does Autotrol Logix 760 backwash at an excessively high rate?
If the Autotrol Control Unit backwashes or purges at an excessively low or high rate, it could be due to using an incorrect drain controller, so replace it with the correct size controller. Another cause may be foreign matter affecting valve operation, so remove the drain controller and clean the ball and seat.
Why is there no conditioned water after regeneration in my Autotrol Control Unit?
If there is no conditioned water after regeneration with your Autotrol Control Unit, it could be due to a few reasons. First, check if there is no regenerant in the regenerant tank and add regenerant to the regenerant tank. Second, the injector might be plugged, so clean the injector and screen. Third, the air check valve might be closing prematurely, so put the control momentarily into brine/slow rinse, C2. Replace or repair air check if needed.
What to do if Autotrol Logix 760 has flowing water at drain after regeneration?
If you have flowing or dripping water at the drain or brine line after regeneration with your Autotrol Control Unit, it may be because the valve stem return spring is weak and needs replacement. Another cause may be that debris is preventing the valve disc from closing, so remove the debris.
Why won't my Autotrol Logix 760 valve draw brine?
If the Autotrol Control Unit valve won't draw brine, it could be due to low water pressure, so set the pump to maintain 20 psi at the softener. It could also be due to a restricted drain line, so change the drain to remove the restriction. Another reason may be that the injector is plugged, so clean the injector and screen. Finally, the air check valve may be closing prematurely on the 255 valve or brine pickup tube. Put the control momentarily into brine/slow rinse, C2. Replace or repair air check if needed.
Why is my Autotrol Control Unit drawing regenerant intermittently?
If you're experiencing intermittent or irregular regenerant draw with your Autotrol Control Unit, it could be due to low water pressure. Set the pump to maintain 20 psi at the conditioner. Another possible cause is a defective injector, which would require replacement.
Why is my Autotrol Logix 760 Control Unit using more or less salt than the regenerant setting?
If the Autotrol Control Unit is using more or less salt than the regenerant setting, there might be foreign matter in the valve causing incorrect flow rates. Remove the brine control and flush out any foreign matter. Advance the control to brine/slow rinse, C2, to clean the valve, then position the control to “fast rinse, C7” to remove regenerant from the tank.
What causes brine tank overflow in Autotrol Control Unit?
If you experience a brine tank overflow with the Autotrol Control Unit, it could be due to: 1. Uncontrolled brine refill flow rate. Remove brine control to clean ball and seat. 2. Air leak in brine line to air check. Check all connections in brine line for leaks. Refer to instructions. 3. Drain control clogged with resin or other debris. Clean drain control.
What to do if Autotrol Control Unit displays ERR 3?
If the Autotrol Control Unit displays ERR 3, it means the controller can't determine the camshaft's position and the camshaft should be rotating to find Home position. Wait two minutes for the controller to return to the Home position; an hourglass should flash on the display, indicating the motor is running. If the camshaft isn't turning, check the motor connection, wire harness connections, optical sensor, and motor gear engagement. If the camshaft turns for more than five minutes, verify the optical sensor and camshaft connections, and check for obstructions in the cam slots. If problems persist, replace the wire harness, motor, optical sensor, and controller in that order.
