(all with 5 minute delays). Range is 0.6 to 900 sec. (15 min.). Constant feed is ‘con’. Other: See the appropriate manual sections for: calibrating the pH sensor changing function (acid/base feed) Rola-Chem Digital Controller PN 554212 11/22/06 Page: 2 of 16...
Locate cord to minimize abuse from lawn mowers, trimmers and other equipment. Replace damaged cords immediately. Do not use extension cords. WARNING: Do not install within an outer enclose or beneath skirt of tub or spa unless so marked. Rola-Chem Digital Controller PN 554212 11/22/06 Page: 4 of 16...
An internal terminal strip is provided for field wiring of the controller. The internal step-down transformer has a class-two energy limiting rating to provide for electrical safety. Rola-Chem Digital Controller PN 554212 11/22/06 Page: 5 of 16...
AUTO mode: This is normal operation mode. The controller operates the feeder to automatically maintain the parameters set for pH. Rola-Chem Digital Controller PN 554212 11/22/06 Page: 7 of 16...
3.3 Power access panel Access to terminals is through the back of the enclosure. With the controller removed from wall/panel, remove four screws holding enclosure panel to enclosure body. Rola-Chem Digital Controller PN 554212 11/22/06 Page: 8 of 16...
If a flow switch is not attached, the flow lamp will be illuminated if there is a jumper in the flow cell terminal. It is recommended that a flow switch always be used. Rola-Chem Digital Controller PN 554212 11/22/06...
The feed lamp should come on if the controller is in acid feed mode. If the controller is in base feed, the feed lamp will come on if the pH indicated is below the pH “set” level. Rola-Chem Digital Controller PN 554212 11/22/06...
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. Rola-Chem Digital Controller PN 554212 11/22/06 Page: 11 of 16...
* Pump/feeders must be large enough to reach desired set-points in a relatively short time. Automation using controllers may require larger feeder or more concentrated chemicals than system that uses continuous time controlled feeding (i.e. feeders only).
