The ACC2 controller allows up to six Pump and/or Master Valve outputs to be assigned in the controller. This applies to the decoder and conventional models. In this article, the following topics are covered:
The Pump/Master valve connections are located on the upper left-hand side of the Power Module.
P/MV OUTPUT: This output determines which P/MV terminal on the Power Supply Board will be used. P/MV outputs 4, 5, and 6 can be assigned to regular station outputs. The default for these outputs is DISABLED. See Soft P/MV (Outputs 4-6) further down this page.
P/MV LOCATION (Decoder Model Only): The Pump or Master Valve can be used on the two-wire path with an ICD-100 decoder or hardwired to the power module like a conventional version.
P/MV STYLE: Each P/MV will be selected as a default NORMALLY CLOSED operation. This is a station level setting, meaning the P/MV is activated by stations when they begin the cycle. The STATION SETUP menu allows you to set each station for the P/MV outputs it needs to run water. NORMALLY OPEN may also be selected and is discussed further in the Flow Operations section. Normally Open is not a station level setting. The valve is always open until a problem is detected at the Flow Zone, or MainSafe level when the controller activates the normally-open P/MV to shut the water off. Ability to schedule Normally Open P/MVs to be exercised for 1 minute based on an interval schedule and time.
P/MV OFF DELAY: This sets how long the P/MV output will remain active after a station stops calling for it (for example, during Delay Between Stations). It is preset to 15 seconds but can be changed (use caution) up to 60 seconds. Hunter is not responsible for damage to pump components when longer delays are set.
P/MV DIAGNOSTICS: The P/MV Diagnostics screen is to view the status and current draw of each active P/MV output. P/MVs that are not running are not shown.
Prior to programming a Pump or Master Valve decoder in the controller, it should be assigned an output number. Learn more
P/MV outputs 4 through 6 will show as DISABLED by default unless you select one of the station outputs to be used as an additional P/MV. These are called SOFT MV's. Once a station is designated as a P/MV, that is its only function. This should NOT be included in irrigation programs as a regular station. If this is included in the programming, the station number will appear in RED and be removed after you change screens.
