ROLA-CHEM Digital Controller PN 554135 5/04/2017 Page: 15 of 20
6.4 Error Code displayed
If an error code appears in the display the controller can be reset by following this
procedure.
A. Unplug power from controller.
B. Simultaneously depress and hold SET LEVEL and pH CALIB buttons.
While they are depressed, plug in controller power cord.
The displays will read “Ld” and then turn On.
C. Release the buttons.
D. The controller is now in test mode. Test mode shortens minutes to seconds.
E. Turn the controller Off again to exit test mode.
Press MODE to ORP or pH.
Hold MODE button until display reads “oFF”.
Release the MODE button. Only the flow light should be on.
F. Press MODE to turn the controller On and return to operating mode.
The last two steps are extremely important because this puts the controller back in
operating mode. If these two steps are not performed the controller will remain in
test mode and it will not operate properly.
If an error code continues to appear contact ROLA-CHEM service personnel.
