4.2.2 Controller to Driver Wiring

Wiring diagram for Controller to Driver connection, including resistor values for different voltages. — Figure 10: Controller to Driver Wiring Diagram.

Note on Resistors:

R is the voltage limiting resistor in series.
When the interface voltage of the controller is 5V, it is unnecessary to need R; just directly connect.
When the interface voltage is 12V, connect a 1K resistor in series.
When the interface voltage is 24V, connect the 2.7K resistor in series.

4.3 Physical Installation

The pump can be installed using either the ODMA or ODMB method. ODMA includes a rubber shock absorber behind the pump, while ODMB does not. Ensure to specify your preferred installation method if ordering a custom configuration.
