External Control via Digital Inputs

When paired with either the Digital Input Wiring Kit (P/N 353129Z - Almond) or RS-485 Automation Wiring Kit (P/N
356324Z - Black), the pump can be externally controlled by digital input signals.
Note: If the pump is manually stopped using the
Start/Stop button, the pump will not run until the
Start/Stop button is pressed. If the Start/Stop
LED is illuminated, the pump is active and can be
controlled externally.
The communication cable provided with these kits
features a watertight connection that plugs into
the Pump Com Port (Figure 5 on page 5). The
opposite end of the cable has either 6 or 8 conductors
defined in Table 1.
A trigger signal is required to externally control the
pump via digital inputs. This required output signal can
to be provided in one of the following ways:
• By the pump drive. Refer to Using the Pump's
Output Signal.
• By an external low voltage signal. Refer to Using
an External Input Signal on page 7.

Using the Pump's Output Signal

1. Route the communication cable from the Pump Com Port (Figure 5 on page 5) to the control system wiring
compartment.
2. Ensure the cable reaches all necessary terminals and cut to the necessary length.
3. Strip the cable 3/4" (19 mm).
4. Strip all conductors 1/2" (13 mm).
5. If using Digital Input Wiring Kit (P/N
353129Z - Almond): Wire communication
cable to control system as shown in Figure
6A.
If using RS-485 Automation Wiring
Kit (P/N 356324Z - Black): Wire
communication cable to control system as
shown in Figure 6B.
Note: Unused conductors should be cut
off and terminated according to local
and national electrical codes.
6. Using the pump keypad, program the
pump's internal clock. Refer to Setting the
Clock and Pump Address on page 8.
7. Using the pump keypad, set PROGRAM 1
to 0 RPM and a duration of 24 hours. Refer
to Programming Custom Schedules on
page 8.
8. Using the pump keypad, disable priming.
Refer to Priming Adjustment on page 11.
9. When ready to start the pump, place the
pump into External Control Only mode.
Refer to External Control Only Mode on
page 7.
10. Plug the communication cable into the
Pump Com Port.
