Connecting To External Controls; Using The Supplied Low Voltage Signal For Digital Control - STA-RITE SUPERMAX VS Manuel D'installation

Control with External Control and Digital Inputs
The user can run the SuperMax
programmed Speeds to be controlled remotely. The pump has a sealed connector that can be used with Pentair
External Control Wiring Kit (Pentair P/N 353129Z) to run the Speeds using digital input signals. When there is an
external low voltage signal present on the Speed Digital Input line, the pump will run the speed programmed for that
Digital Input. The supplied +5V signal is the recommended input used for external control and Speed Digital Inputs.

Connecting to External Controls

Using the Supplied Low Voltage Signal for Digital Control

The SuperMax VS pump provides a low voltage output signal that can be used to trigger its own Digital Inputs. This
signal will need to be switched via the External Control system to engage the speed that it is connected to as in Figure
4. This could be an automation relay or switch in another piece of equipment. This feature could be useful for ensuring
that the pump is running a certain program when a specific speed is needed to perform a task.
The wire included with the External Control Wiring Kit (Pentair P/N 353129Z) will need to be cut to length for the
installation. Do not leave excess wire around the installation, and the wire should be supported by something rigid
if conduit is not used. At one end of the cable is a custom molded, watertight connection that plugs into the panel
connection on the side of the drive. The opposite end has 6 wires that are defined by Table 1 below. When using the
+5V signal supplied by the drive, the speeds should be wired as shown in Figure 4.
When there is a low voltage signal present on the Speed Digital Input line the pump will run the speed that is
programmed for the speed that is being triggered. The +5V signal supplied via the (red) wire is the suggested input for
the Speed Digital Inputs. See Figure 4.
Note: Any relay can be associated to any Digital Input. Figure 4 shows one of many potential wiring options available
to the installer, allowing you to install External Controls in the way that best suits your needs.
Note: This +5V Signal (red wire) is output from the drive only, and should never be wired to another power
supply!
When a Speed Digital Input is triggered, the LED above the Speed button will begin to blink and the display will toggle
between the display parameter and "EC" indicating an External Control is running. The pump will run this speed as
long as the Digital Input trigger is present. This will override the schedule or any user inputs for Speed selections via
the keypad. The Display button is still functional along with the Start/Stop button. Once the Digital Input trigger is
removed from all of the Speed Digital Input wires, the pump will resume the programmed schedule.
