Note 1: Resistance increases as the temperature rises on
the pump or motor solenoid coil, resulting in decreased
current values when measured with a meter. The listing in
the table is the current range for a 21°C (68.9°F) coil.
Note 2: The node regulates displacement of the pump or
motor with a PWM output. The values represent the
beginning and end of the control range.
