Signal response
Switch
TTL compatible signals
Factory Default (RS)
Open = start pump
High 5V = start pump
Inverted(IRS)

Manual operation with a remote stop/start switch
If you invert the operation of the remote stop/start switch you must connect a wire link from pin 7 to 17 to be
able to start the pump from the keypad. This diagram shows the combined effects of the remote switch and the
pump keypad.
If
is pressed the remote stop/start switch will have no effect.
Direction
Connect remote direction switch between pins 5 and 17. Also link pins 6 and 18 to enable remote direction control.
The
and
keys on the pump will be disabled. Open switch for clockwise rotation, close switch for counter-
clockwise rotation. With no connection, the pump will default to clockwise rotation. Or a TTL compatible logic
signal may be applied to pin 5. (Ground to pin 17). High (5V maximum) for clockwise rotation. Low (0V) for
counter-clockwise rotation.
You cannot invert the remote direction signal.
