Using an Externally Supplied Low Voltage Signal for External Control
When using an externally supplied low voltage signal as the Digital Input trigger, the wire should be connected as
shown in
Figure 5
. The low voltage input needs to be within the range of 5-30V AC or DC. In this case the red +5V
supply from the motor control will not be used.
Note: This +5V signal (red wire) is output from the drive only and should never be wired to a voltage supply!
The external low voltage signal can be regulated by switches or relays to activate the desired Digital Input. If more
than one Digital Input is active at one time then they will be resolved by priority.
Note:
If the pump has been stopped via the
Start/Stop
button, the pump will not run until the pump is turned back on
by pressing the
Start/Stop
button. If the
Start/Stop
LED is illuminated, that indicates the pump is on and will run via
Digital Inputs.
Note:
If multiple low voltage triggers are present it will be resolved by this priority: Quick Clean, Speed 3, Speed 2, and
then Speed 1.

To activate External Control Only mode:
1. Stop the pump by pressing the
Start/Stop
button.
2. Activate External Control Only mode by pressing and
holding the
Start/Stop
button for 10 seconds.
3. If successful the LED next to Ext. Control Only will
illuminate. See
Figure 6
.
4. The
Start/Stop
button must be pressed again to
allow the pump to run.
To deactivate External Control Only mode:
1. Stop the pump by pressing the
Start/Stop
button.
2. Deactivate External Control Only mode by pressing
and holding the
Start/Stop
button for 10 seconds.
3. If successful the LED next to Ext. Control Only will
turn off. See
Figure 6
.
4. The
Start/Stop
button
must be pressed again to
allow the pump to run.
External Control Only Mode
External Control Only mode will only allow the pump to run from external controls/inputs. When this mode is active
the programmed pump schedule is deactivated, and user speed requests from the keypad will not be accepted. If the
pump is stopped a user can still program the speeds for all four
Speed
buttons.
