The controller incorporates an internal non-volatile memory in which all factory default settings as well as field-modified settings are stored. The internal memory is not affected by power interruption and requires no backup battery. ® ROLA-CHEM Digital Controller PN 554135 07/11/19... - Page 6 Generally, automating an existing body of water with existing feeders will require the output of the feeders be increased accordingly.

* 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). ® ROLA-CHEM Digital Controller PN 554135 07/11/19... - Page 18 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. 6.5 Digital Display numbers flashing * Consecutive Feed Alert Limit has been reached.

Questions and answers
My rolachem cheical feeder freezes and stop feeding cheicals automaticly why.
The ROLA-CHEM RC554XP chemical feeder stops feeding chemicals automatically when the preset Consecutive Feed Alert Limit is reached. This occurs if the pH or ORP chemical feeder outputs continuously feed for the set time period (20 to 180 minutes). When this limit is reached, the respective feeder output is disabled, and its display flashes to indicate a Consecutive Feed Alert.
