The revision numbers should be identical for both units. Unpredictable or unstable operation may result
from mismatched software revisions.
Please note that it may be necessary to adjust the display contrast. Please refer to Section 8.6 if this is
required.
6.5 Motor Parameter Setup
The MPC VECTOR controller interfaces closely with the Eclipse pump motor. The MPC VECTOR needs to
know certain details about the motor in order to function properly. End users may have to input or adjust
motor parameters before operation. Use the following as a guide:
If you: Have received your MPC VECTOR and Eclipse pump and motor as a unit from the factory,
and Your MPC VECTOR to motor wiring distance is less than 25 feet
Then you should not have to perform any parameter setup or calibration. All parameters and setup have been
completed for you at the factory.
If you: Are using the MPC VECTOR with a motor that did not come from the factory, or
Your MPC VECTOR to motor wiring distance is greater than 25 feet, or
You are replacing the motor on an existing setup
Then you may have to enter the motor parameters, and you will have to perform a motor auto-setup
procedure. Please reference Section 10, Motor Parameter Setup and Tuning, before proceeding with
operation of your MPC VECTOR controller.
6.6 Setting Max Flow and Max Speed
What is Max Flow?
The value entered into the Max Flow is largely used for display purposes. It limits the flow rates that can be
entered during normal operations, as well as during analog calibration routines and PulsaGuard calibration.
Internally it is also used in PID calculations.
What should my Max Flow be set to?
Max Flow can vary for a gear pump based on the viscosity of the fluid being pumped and the system
pressure. It is recommended that the Max Flow be set 10% higher than your pump is rated for at 0PSI. This
will allow for a full range of data entry.
What if I try to set my pump to a flow higher than it can actually achieve for my current pressure and
viscosity?
The pump has internal software protections and validations which prevent the motor from exceeding 1800
RPM (approximate). If the pump can only achieve 2.5GPM at 1800 RPM for your system configuration and
the flow rate is set to 10GPM, the motor will spin at 1800 RPM and produce 2.5GPM.
What is Max Speed?
Max Speed is the maximum speed that the motor can spin, according to the manufacturer. This is largely
unused by the MPC Vector at the moment and will not affect operations. It is recommended that this value is
kept at 1800 RPM.
