Connecting AC Main Power, Wall mount cabinet The ACC can operate with either 120VAC or 230VAC power, depending on how the incoming AC wires are connected. Supply wires must be 14AWG (1.85mm) or larger.

    The 120V~ ground wire (bare, or green) is not used in ACC transformer connections. The service ground wire may be connected to earth ground if required. Tighten screw and replace cover. For 230V~ operation, connect the incoming power wire (hot, brown in many wiring standards) to align in the wiring block with the brown wire lead from the transformer.

  • Page 34: Flow Alarms

    Flow Alarms Once station flow has been learned, ACC will always compare actual flow from the flow meter to the learned flow (even when multiple stations are running). When the actual flow exceeds the limit over learned flow, after the specified delay has elapsed, an alarm will occur.

  • Page 35: Alarm Logs (Also See Historical Data/Data History Section)

    (Over or Under). Tips on Flow Alarms: • There is only one flow meter per ACC controller, and controllers do not share information with one another. If a controller with a meter “sees” flow caused by another controller, drawing water from the same point of connection to the water supply, the controller will experience many false alarms, because it cannot account for the flow.

    Overflow: A station has exceeded its learned flow upper limit during irrigation. ACC totals the upper limit of the learned flow for all running stations, and compares them to the actual flow at the flow meter. When the combination of stations exceeds the total upper limits (after all Delay times have elapsed), the controller will Pause and go into alarm diagnostic mode.
