OPERATION
Control with External Control and Digital Inputs
The user can run the Ecoclear® 1500-VS Pool Pump Variable Speed Pump with
automation external controls, allowing all four 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 Ecoclear® 1500-VS Pool 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
10. 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 moulded, 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 10. 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 10.
Note: Any relay can be associated to any Digital Input. Figure 10 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.
