Rola-Chem 554230 ORP Digital Controller - Manual (Page 10)

4.5 Reset
The controller can be reset at any time to the default factory settings. Follow the
steps below: (note: ‘Re-Set’ button is unmarked and located directly to the right of
the Feed Time button).
A. Press ‘Mode’ button to turn ‘Auto’ light off.
B. Hold ‘Mode’ button until ‘OFF’ is displayed.
Release ‘Mode’ button. Display should be blank.
C. Hold the ‘Set Level’ and ‘Re-Set’ buttons and then the press Mode button (all
three buttons held at same time).
D. The display will read ‘LD’ and then a number.
E. Release the buttons.
F. Turn the controller ‘off’ and then ‘on’.
Note: This last step is extremely important since this puts the controller
back in the operating mode. If step F is not performed, the controller is in
the test mode and it will not operate correctly.
5.0 Troubleshooting-
5.1 Chemicals not feeding
* FLOW light on Controller must be illuminated.
Check flow switch (manifold) if light is not on (Section 3.3.3)
* Feeder power and time switches must be in ‘ON’ position.
Check feeder by using alternate power source.
* Factory setting for feed time is 0.6 sec on with 5 minute delay.
Feeders may require longer feed time.
5.2 Displayed chemical level don’t correspond to actual
* Sensor (probe) is not attached connector.
* Sensor (probe) needs cleaning.
* Sensor (probe) needs replacing.
5.3 Set-points not being reached or maintained
*
Factory setting for feed time is 0.6 sec on with 5 minute delay. Feeders may require
longer feed time. If time is too short, set-points will not be maintained. If time is too
long, overfeeding chemicals will occur. Correct time is dependent of multiple
factors such as pool/spa water volume, feeder output, chemical concentration and
chemical needs.
