Important: general instructions for remote control inputs

All remote control inputs can be wired in two ways:

Logic

A logic voltage between 5V TTL and 24V industrial logic may be wired to the input. The pump is configured to operate without modification anywhere in this range. Any of the 0V terminals - though preferably the 0V terminal associated with the desired input - is connected to the control device’s 0V to make the circuit. Low is equivalent to 0V. High is equivalent to 5V￿24V.

Switch

A remote switch may be connected between the input and any positive voltage supply from the pump - though preferably the associated sup- ply terminal. Do not use the 10V supply from the Rem-pot connector, however.

22.7 Run / stop input

Remote run / stop: connect a remote switch between the i/p terminal and the +5V terminal of the Run/stop i/p connector (J4). Alternatively a logic input may be applied to the i/p ter- minal, ground to the 0V terminal. High input stops the pump, low input runs the pump. With no connection or with the switch open, the pump will default to running. To change or set the sense of the run / stop input, see 18.11 Remote stop in the Setup menu.

22.8 Direction input

To enable remote direction control and disable the DIRECTION key on the keypad, link the terminals of the Direction enable link connector (J6).

Important: Apply no voltage what- ever to the Direction enable link. Connect a remote switch between the +5V terminal and the i/p terminal of the Direction i/p connector (J2). Open switch for clockwise rotation, closed switch for counter-clockwise rotation. Alternatively a logic signal may be

applied to the i/p terminal and the 0V terminal of the Direction i/p connector (J2). Low input for clockwise rotation, high input for counter-clockwise rotation. With no connection the pump defaults to clockwise rotation.
