5.2 Installation Notes
The MPC VECTOR is a microprocessor-based controller that uses electro-static sensitive CMOS
components. Do not make any (high or low voltage) electrical connections without adequately grounding
the MPC VECTOR and the worker to eliminate an electro-static charge between the two. A conductive
wrist strap worn by the worker and attached to the MPC VECTOR’s internal ground plate is
adequate to satisfy this requirement.
Calibration is an important element of successful MPC VECTOR operation. If a flow meter is being used for
process feedback the flow meter must be calibrated prior to MPC VECTOR calibration according to
manufacturer recommendations.
Conduit connections can carry fluids and vapors into the MPC VECTOR causing damage and void the
warranty. Care should be taken when installing conduit to protect against fluid/vapor entry. If necessary,
provide sealed entries or conduit drains near the point of entry. The user must supply the correct connection
for the power entry, as per the local codes and requirements. Any cable entrances that are not used should
be appropriately sealed against moisture and vapors.
5.3 Electrical Wiring
Wait a minimum of 5 minutes after disconnecting power before servicing the MPC VECTOR or
pump motor. Capacitors retain a charge even after power is removed from the controller.
1. Make the motor connections between the control unit and the pump motor (ref. Figure 3).
2. Make the incoming AC power connections and the outgoing power connections to the pump motor (ref.
Section 5.3.2). These will allow you to operate the MPC VECTOR and attached Eclipse pump.
3. Decide which signal (control) Inputs and Outputs (e.g., 4-20mA in) will be used and make those
connections (ref. Section 5.3.4).
4. Power-up and test the MPC VECTOR to confirm the connections and check for proper operation.
5. Configure the software via the menu system for the desired operational conditions. Depending on the
anticipated function, users may need to enter settings for the following:
a. Analog input signal, so the MPC VECTOR can accept a process input signal
b. Digital input settings, for example start/stop and/or tank level inputs
c. Digital output settings, for example auto/manual status and/or alarm outputs
6. Conduct a final power-up and test the MPC VECTOR to confirm the connections and check for proper
operation.
7. Go to the Section 6 – Start Up and Operation for details on how to perform the power-up tests.
5.3.1 Controller Layout
The design of the MPC VECTOR incorporates all control circuitry onto one easily accessed circuit board.
This board is located on the inside of the main controller. Gain access to this board by removing the 2
cover screws allowing the cover to hinge open.
