1. Introduction
The MPC VECTOR is a microprocessor based motor speed control device, for use with Pulsafeeder pumps. It has been designed for simplicity, yet still has many advanced features that allow the MPC VECTOR to operate in a wide variety of environments and applications. This product is not just a variable speed drive. It is a state of the art multifunctional controller, which provides functionally no one stand-alone variable speed drive does. What makes this product unique is that it combines functionality of three devices in one:
Vector type variable speed drive.
Input output processor (4-20 mA in and out, digital input/output), including PID loop for closed loop flow
control.
Power monitor for detection of run-dry conditions
This instruction manual covers the MPC VECTOR control only. For information and safety precautions specific to the pump or any other accessories, please refer to the appropriate IOM.
1.1 Description
The MPC VECTOR is an advanced pump controller that is physically separated from the pump's enclosure. Its purpose is to precisely adjust output flow of a process media by means of pump motor speed control.
The MPC VECTOR is designed for a wide variety of control applications. If delivered with a pump and motor, the device is factory configured. Field configuration may be required in certain installations. Local setup and control is achieved through the keypad and a backlit two-line liquid crystal display. Basic operation is simple with dedicated function keys eliminating the need for a sophisticated menu system. Pump output is displayed as Gallons or Liters per Hour (GPH/LPH), Gallons or Liters per Minute (GPM/LPM), or Revolutions per Minute (RPM).
Digital and analog inputs will support a variety of industry standard signals to offer flexible remote control.
The MPC VECTOR is designed to simplify and automate the calibration of pump flow and analog signals. Flow calibration uses on-screen prompting and automated pump operation to eliminate stopwatches, calculators and human inaccuracies. Analog signal calibration is also accomplished by simple keypad entry. It includes a real­time display of signal level. This eliminates the need for external meters.
The MPC VECTOR will accept, and automatically adjust to, either 60 Hz or 50 Hz input power. No special modifications, settings, or adjustments are required. MPC VECTOR controller can be supplied with a 60 Hz, 50 Hz, or dual rated 50/60 Hz motor. The controller/motor combination allows for 60 Hz rated pump flow (1800 rpm motor speed) even when operating from a 50 Hz input. Users in locations with 50 Hz AC supply do not have to de-rate pump flow with this controller.
Minimum motor speed is limited under all circumstances to 31 rpm. Please note that in certain applications, the practical minimum speed (to achieve flow and pressure) may be higher than 31 rpm. This can be dependent on product viscosity and other application-specific variables.
Input Frequency MPC VECTOR Motor Max MPC VECTOR Output
60 Hz (USA and similar) 60 Hz (or dual rated) 60 Hz / 1800 rpm
50 Hz (Europe, Asia, etc) 50 Hz or 60 Hz or dual rated 60 Hz / 1800 rpm

The motor used with the MPC VECTOR is a three-phase motor; however the three-phase power is generated internally by the MPC VECTOR itself. Do not be confused by the motor nameplate. Input power to the MPC VECTOR is single-phase or three-phase AC 230 volts (see Section 12, Specifications for acceptable voltage range). The nameplate on the side of your MPC VECTOR controller will list the appropriate supply requirements for your controller.
Motor Hp Rating MPC VECTOR Input Power* Output to Motor**
1 208/230 VAC 1 or 3 phase 230 VAC 3 phase
2 208/230 VAC 1 or 3 phase 230 VAC 3 phase
3 208/230 VAC 1 or 3 phase 230 VAC 3 phase
5 208/230 VAC 3 phase only 230 VAC 3 phase
* all input ratings are 50 or 60 Hz ** output to pump motor is always 60 Hz maximum frequency
The AC drive used in the MPC VECTOR maintains tight control over voltage and current supplied to the pump motor. This results in lower motor operating temperatures and less stress on motor windings, resulting in longer motor life and more reliable overall operation. Further motor selection information can be found in Section 12, Specifications at the end of this manual.

2. Safety Considerations
Read and understand all related instructions and documentation before attempting to install or maintain this
equipment
Observe all special instructions, notes, and cautions.
Act with care and exercise good common sense and judgment during all installation, adjustment, and
maintenance procedures.
Ensure that all safety rules, work procedures, and standards that are applicable to your company and facility
are followed during the installation, maintenance, and operation of this equipment.
2.1 General Safety
The MPC VECTOR was designed as a controller for operation solely with the Pulsafeeder Eclipse series of non-metallic gear pumps. Use for any other application is considered unsafe and voids all certification markings and warranties.
2.2 Electrical Safety
The MPC VECTOR is an industrial process controller. Improper application and use can be hazardous. You are solely responsible for its use.
The MPC VECTOR electrical installation must conform to all relevant electrical codes. Installation and electrical maintenance must be performed by a qualified electrician. Before installing or servicing this device, all power must be disconnected from the source at the main distribution panel.
The MPC VECTOR emits electro-magnetic energy and may generate radio frequency interference. Its use is restricted to industrial applications. You are responsible for shielding this energy/interference.
Certain wiring procedures may require that the user wear a wrist strap to dissipate static charges.
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.
2.3 Mechanical Safety
Users should note that the pump motor is always under the control of the MPC VECTOR, and as such may actuate without warning. Care should be taken to keep loose clothing and other objects away from the pump motor.
The MPC VECTOR was designed to be service free. It contains no user-maintainable components. Disassemble the MPC VECTOR enclosure only for initial field wiring, or as instructed to do so within this manual. Evidence of unauthorized disassembly shall void the warranty.
2.4 Hydraulic Safety
Thoroughly review and adhere to the contents of the pump Installation, Operation, Maintenance and Instruction manual for any pump used with the MPC Vector control. As a microprocessor controlled device, the MPC VECTOR may activate the pump motor without warning – generating hydraulic pressure and fluid flow. Care should be taken to protect both users and systems should the pump activate.

3. Equipment Inspection
When you receive your order, check all equipment for:
Completeness against the shipping document / purchase order
For any evidence of shipping damage.
Shortages or damage should be reported immediately to the carrier and your Pulsafeeder Representative.
4. Storage Instructions
The MPC VECTOR can be successfully stored for extended periods. The key to this success is temperature and humidity control.
4.1 Short Term (0 - 12 months)
The MPC VECTOR should be stored in a temperature and humidity controlled environment. It is preferable to keep the temperature constant in the range of -18° to 60° Celsius (0° to 140° Fahrenheit). The relative humidity should be 0 to 90% non-condensing.
4.2 Long Term (12 months or more)
Storage of the MPC VECTOR for periods of longer than twelve months is not recommended. If extended storage is unavoidable the MPC VECTOR should be stored in accordance with those conditions stipulated for Short Term Storage. In addition, a porous bag of 85g (3 oz) silica gel or similar desiccant should be placed inside the enclosure. The cover should be re-installed to seal the desiccant within the enclosure. The conduit connections must be tightly capped.
Special note for long-term storage:
If AC input power has not been applied to the MPC VECTOR for a period greater than 12 months, the controller must be prepared for operation. The MPC VECTOR should have AC power applied at the input for a period of 8 hours before placing pump into normal operation. Refer to Installation and Wiring section for AC power connection instructions.

5. Installation and Wiring
5.1 Location
Review the Safety section (Section 2) prior to installing the MPC VECTOR. It contains information required to properly install and operate the MPC VECTOR in an industrial environment.
The site selected for the installation of your MPC VECTOR is largely dependent on that of the gear pump. Review the Installation, Operation, and Maintenance manual provided with your gear pump. It details system related issues that are important to proper operation of the pump. Consider the following MPC VECTOR related issues when selecting a site. Avoid locations where the MPC VECTOR would be subjected to extreme cold or heat. Note the warning statement on the next page. The installation of this device must comply with national, state and local codes.
The MPC VECTOR controller must be secured to an appropriate support before use. Use appropriate hardware to secure the MPC VECTOR controller and pump to a smooth vertical surface. No assembly is required for the MPC VECTOR controller itself.

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.

5.3.2 Power Wiring Information
Verify the correct supply voltage (230VAC single-phase or three-phase) with the nameplate
affixed to your MPC VECTOR. Ensure that your supply voltage matches the MPC VECTOR configuration.
The 1 hp, 2 hp, and 3 hp AC drives use single phase or three phase 230VAC input. The 5 hp
AC drive must be powered by three phase 230VAC input only.
Wires should be routed within the enclosure in a manner that maintains separation between
high voltage and low voltage conductors. High voltage conductors should be routed to the side opposite the control circuitry.
Incoming power wiring should adhere to all applicable local and national electrical codes and
regulations. A circuit breaker or fuse must be provided as noted below.
Upon initial application of AC power, a current inrush will occur to charge the DC bus
capacitors. This is normal operation, and breakers and other circuit protection devices should be sized accordingly.
The MPC VECTOR requires one connection to an external power source. It uses this same connection to power its own supply as well as the AC pump motor. You must take all of these loads into consideration when sizing the branch circuit (see Table 1). A circuit breaker or disconnect switch with fuses must be wired in series with terminals L1 and L2/N in accordance with all applicable local and national electrical codes and regulations. The circuit breaker or disconnect switch shall be located in close proximity to the MPC VECTOR controller installation, and must be marked or labeled to identify it as the power disconnect for the MPC VECTOR.

5.4 Check Wiring and Close Access Cover
Double-check all of your electrical connections. Pay attention to polarity of all inputs and outputs – both low and high voltage. Additionally, insure that all terminals are clamping onto the bare conductor, not on its insulation. Ensure that wires will not be trapped or pinched when front cover is replaced and secured. Ensure that excess insulation is not removed from the wires, as this can lead to poor connections or faulty operation.
Replace the main access cover and secure the 2 screws.
5.5 Confirm Correct Incoming Power
W
ITHOUT PRIOR OPERATING KNOWLEDGE, IT IS IMPOSSIBLE TO TELL IF THE PUMP MOTOR WILL RUN WHEN POWER IS APPLIED TO THE NECESSARY STEPS TO ENSURE THAT ALL ASPECTS OF SAFETY HAVE BEEN CONSIDERED (E.G., ELECTRICAL, HYDRAULIC, ETC
.).
Turn on power at the mains or distribution panel. If the MPC VECTOR's incoming power is connected correctly, the backlighting on the MPC VECTOR’s display will illuminate (depending on lighting conditions, it may be necessary to shade the display to confirm illumination). If the display is not illuminated, first check the line voltage with a voltmeter. If the voltage is not correct, return to Section

6.4 Confirm Display and Keypad Functionality
The example display messages are shown in English for demonstration purposes. If an alternate language has been set, the text is displayed as a translation of the English version.
Now that you have confirmed that the MPC VECTOR is receiving power, it is necessary to confirm that the display and keypad are functioning properly. On normal power-up, the display appears for approximately 2 seconds.
P U L S A F E E D E R INC.
F W : 0 0 . 0 0 / 0 0.00
The first four digits displayed are the software revision for the MPC VECTOR control board, and the second four indicate the software revision for the remote board.

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.

6.7 Flow Display
The MPC VECTOR will display calibrated pump flow in GPH, LPH, GPM, or LPM on the digital display when configured for flow control. The motor speed (in RPM) may also be viewed while in flow control. Changes to the flow units are made in the System Setup Menu.
6.8 Wrapping up
Your MPC VECTOR is now commissioned for use. Note that you cannot configure the software in a way that would damage the MPC VECTOR. Typically, whenever you are about to set a critical value (e.g., Calibrate Flow), you are always prompted to confirm your change before it takes effect. If you are ever dissatisfied with the configuration of your MPC VECTOR, you can always return to the Factory Defaults by referring to Section 6.7.
16
6.9 Factory Re-Initialization
Factory Re-initialization is typically not required. When re-initializing your MPC VECTOR, all of the system settings and calibration information will be overwritten by the original factory default settings. The controller must be re-configured and re-calibrated to your specifications.
A Factory Re-initialization should be performed only if there is reason to believe that the MPC VECTOR is operating abnormally. The condition usually manifests itself with inconsistent or erratic operation – often associated with meaningless characters on the display, or exaggerated numerical values. Commonly, a user has entered incorrect parameters, or made changes to the setup of the control.
Once a re-initialization has been performed, all operating parameters should be checked and adjusted or re­entered as necessary, including maximum flow and rpm, motor parameters, flow and analog signal calibrations, etc.

7. Input/Output Setup
Use the “DIGITAL I/O” and “ANALOG I/O” menus to activate the functions required for the intended application.
Users may also reference Section 14 – Menu Maps for additional configuration assistance
7.1 Analog Input Setup
Two Analog Inputs are provided for the User. Analog Input 1 is used for Setpoint input. Analog Input 2 is used for systems configured for analog process feedback from a flow meter.
7.1.1 Analog Input 1 – Setpoint
See Figure 4 – Signal Connections to insure that you have your Analog Input signal connected to the proper location before activating. Use the “ANALOG I/O” menu to activate the analog input signal function. The menu can be used to set the analog input to either ACTIVE or INACTIVE. The setpoint input should be calibrated prior to activation (ref. Section 8.2 – Analog Input Calibration).
7.1.2 Analog Input 2 – Flowmeter Feedback
See Section 9 Flow Meter Input for installation instructions. The flow meter input signal must be configured properly prior to use. Use the “FLOW SENSOR” sub-menu under “SYSTEM SETUP” to enable the process feedback analog input. The flow sensor type must be set to “ANALOG” to enable this input. The process feedback input should be calibrated prior to activation (ref. Section 8.1 – Pump Flow Calibration).
7.2 Digital Input Setup
7.2.1 Multi-purpose Digital Inputs
Each of the 2 Digital INPUTS can be selected as: Inactive
Each can be set as normally OPEN or normally CLOSED. For example, if an input is set to ON/OFF and NORMALLY CLOSED, this means a CLOSED switch will activate the pump. A NORMALLY OPEN setup will give the opposite response. These inputs are to be attached to a dry contact circuit only, apply no voltage to these inputs.

7.3 Analog Output Setup
No setup is required for the analog output. Analog output is always available at the corresponding terminals (see wiring diagram Figure 4a, Section 5.3.4). The analog output follows and is proportional to motor speed.
7.4 Digital Output Setup
Each of the 3 Digital OUTPUTS can be selected as: ON/OFF Status AUTO/MAN Status Leak Detected Alarm Indicator Tank Level Status
Each can be set as normally OPEN or normally CLOSED. For example, if an output is set to ON/OFF INDICATION and NORMALLY CLOSED, this means that when the motor is running (indicator lamp is ON) the output will be CLOSED. A NORMALLY OPEN setup will give the opposite response.
Digital output circuits are transistor based and limited to 40 VDC maximum, see Section 5.3.4, Input/Output Signal Wiring, and Section 11, Specifications, for more information).

8. Calibrations
As a convention in this manual:
“WET” calibrations

will refer to those that require normal operating conditions, for example the
“DRY” calibration
or that a specific input signal be present.
Some of the calibration routines may be performed either way. Note any system requirements listed for each routine.
routines are run under other conditions, and often do not require the pump to run
8.1 Pump Flow Calibration
Pump flow calibration is not necessary for the standard speed controller. It is only necessary for models configured for flow meter feedback. The selected flow meter should meet or exceed requirements listed in the Flow Meters section (ref. Section12 - Specifications). The flow meter should also be calibrated prior to MPC VECTOR calibration according to manufacturer specifications.

The pump may be calibrated in WET (under normal operating conditions) or DRY (performed with pump off) conditions.
8.1.1 WET Flow Calibration
The Wet Flow Calibration routine will require that the user turns on the pump. The flow meter should be configured and calibrated prior to MPC VECTOR calibration (refer to flow meter IOM for calibration instructions). Please note that it must be safe to run the pump and dispense liquid into the system in order to complete this calibration. The pump should be fully primed with the product in order to complete an accurate calibration.

8.1.2 DRY Flow Calibration
The DRY Flow Calibration routine does not require the pump to run. Instead, the user may input known flow meter feedback values. This process can be used for fine adjustment of flow rate display, or in situations where it is not possible or not safe to run the pump during calibration.
The DRY Flow Calibration Routine may be used to make small adjustments to the MPC VECTOR calibration to ensure to make the MPC VECTOR display more closely matches the Flow Meter display.
If you are not using a flow meter for feedback, the DRY flow calibration routine can be used, but will display motor RPM instead of mA value during the procedure.

13. Press the MENU key several times to return to Operations Mode.
To optimize feedback, it is best to set 4mA to 0 flow and 20mA to a value slightly higher (10-20% or so) than your max desired flow setting. This allows the user a full range of flow setpoints as well as giving the MPC VECTOR the best possible Analog resolution.
23
8.2 Analog Input Calibration
If you are not using the 4-20mA input to the MPC VECTOR for control, skip this section. To calibrate the Input Current you must first correctly wire an external signal source. Refer to Section 5 – Installation: Low Voltage Input Connections, Analog Input. As with the flow calibration routine, the Analog Input may be calibrated WET or DRY. To perform a WET calibration, the signal-generating device must be active and capable of generating the full range (low to high) of potential input signals. A DRY calibration requires no input signal.
If the MPC VECTOR is configured for Speed Control instead of Flow Control the displays below reflecting pump flow will be replaced with pump speed displays. For example the bottom line of step 8 of the WET Calibration routine will display ‘SPEED XXXX RPM’.

This indicates that there is not a wide enough range between your maximum and minimum analog signals. The minimum signal range is 3 mA. The most likely source of this error is the user did not change the value of the incoming analog signal when moving from the MIN calibration to the MAX calibration.
The analog input signal calibration procedure should be performed again, ensuring that a minimum of 3 mA difference exsists between the MIN and MAX signal levels.

8.4 PulsaGuard Pump Protection
PulsaGuard is designed to turn your pump off when running in dangerous conditions. These conditions are user configurable and can be easily modified to meet each application.
When flow meter feedback is being provided, PulsaGuard will turn off your motor if a low flow set point is crossed for more than 10 seconds. This will protect the pump in under-loaded or overloaded conditions, which would cause the flow to fall below the user’s acceptable limit. The MPC VECTOR will also trigger an alarm condition if the flow set point cannot be reached for some reason. This alarm will be displayed on the MPC MPC VECTOR display but will not shut the motor off. If the MPC VECTOR is operating without flow meter feedback PulsaGuard can read the motor current and shut off the pump if the current drops below the shut off level and stays under that level for 10 seconds, effectively protecting equipment from under-loaded conditions.
The PulsaGuard pump protection may be enabled and disabled as desired from the System Setup menus (see section 8.4.2: PulsaGuard Enable/Disable). Note that once a calibration is performed the pump protection is automatically enabled, you will not have to manually enable it.

8.6 Tuning the Control Algorithm
This option should only be used by control systems engineers who are familiar with tuning PID loops. This is not intended for the casual user. Changing these values may result in the system oscillating without settling on the set point or never reaching the set point at all. See Section 21, Appendix 2 for more information and theory on PID control.
The MPC VECTOR allows users to tune the motor control algorithm to speed up or slow down the MPC VECTOR response time. This is done by adjusting the PID Controller parameter coefficients.

9. Flow Meter Input
The MPC VECTOR accepts flow meter process feedback from an analog (4-20mA) flow metering device. The manufacturer of the flow meter is not important but the process signal must conform to a set of minimum specifications in order to work with the MPC VECTOR.
9.1 Flow Meter Installation
Prior to installation make sure your flow meter conforms to the MPC VECTOR’s flow meter specifications (refer to Section 13, Specifications). Your flow meter must also be calibrated independently prior to installation.
Figure 5 – Flow Meter Connection
1. Remove MPC VECTOR power and wait 30 seconds for complete power dissipation.
2. Connect your flow meter input to the Flow Meter Input Terminal Block (ref Fig. X.XX).

10. Motor Parameter Setup and Tuning
The MPC VECTOR controller must know several motor characteristics before the motor can be calibrated. This calibration allows the controller to maintain precise control over the operation of the motor.
If the drive has not been calibrated an error will appear on the screen. In addition, at startup the User Interface will be redirected to the Calibration/Motor Parameter sub-menu.
If your MPC VECTOR unit has been shipped from the factory as a complete unit with Eclipse pump and motor, these parameters will have been entered at the factory. No further user input will be required.
Note that the ranges listed in the table below reflect absolute min/max accepted by the drive and may not match a specific application. These do not have to be set in any particular order but will be presented sequentially by the User Interface. The parameters will need to be entered in the field if the MPC VECTOR controller was shipped without a motor, or if the motor is changed to a different model than was originally supplied.

ETTING THESE PARAMETERS IMPROPERLY AND RUNNING THE AUTO-CALIBRATION ROUTINE CAN
RESULT IN DRIVE ERRORS.

1. Open the handheld unit by removing the 4 screws on the face of the unit.
2. Open the unit by separating the cover from the base.
3. Use care with the keypad tail that is connected to the board, it can be left in place during this process.
4. Make a note of what color lead is in each position of the terminal block “J5”. Cut the tie-wrap that
secures the cable. Unscrew each screw on the terminal block “J5” and remove each lead.
5. Loosen the outer domed nut on the liquid tight, releasing the tension on the cable. Pull the cable
through the liquid tight. Thread the new cable through the liquid tight with enough length to reconnect to the terminal block.
6. Cut the shield wire as close as possible to the outer insulation at the remote end only.
7. Wrap the end of the cable with electrical tape to insulate any remaining shield so that it will not
contact the circuit board, equipment case, or any other parts.
8. Referring to the notes taken earlier, connect each lead of the new cable to the proper position of the
terminal block, lock the lever back in place to hold lead. NOTE: It is recommended that you insert and secure one lead at a time.
9. Tighten the dome nut of the liquid tight to secure/seal cable.
10. Check that the keypad tail is still firmly connected, re-insert if necessary.
11. Replace cover and tighten screws. Be sure the o-ring is in its groove, paying special attention to the
corners. NOTE: Do not over tighten.
54
20.2 Removal and Connection of the Cable from the Base Unit:
Wait a minimum of 5 minutes after disconnecting power before servicing the MPC or pump motor. Capacitors retain a charge even after power is removed from the controller.
1. Remove the screws that are securing the cover of the main unit.
2. CAUTION: The cover is wired and should be opened gently being sure not to pull any of the wires
that are connected to it.
3. Make a note of what color lead is in each position of the terminal block “J14”. Unscrew each screw on
the terminal block “J14” and remove each lead.
4. Loosen the outer domed nut on the liquid tight, releasing the tension on the cable. Pull the cable
through the liquid tight. Thread the new cable through the liquid tight with enough length to reconnect to the terminal block.
5. Prepare the end of the cable as per figure 7 on the following page. Ensure that the shield is fully
insulated until the point where it enters the terminal. No part of the shield should be allowed to come in contact with the circuit board, equipment case, or any other surface.
6. Note that the black-green lead should be paired with the green wire.
7. Referring to the notes taken earlier, connect each lead of the new cable to the proper position of the
terminal block, and then lock the lever back in place to hold lead. NOTE: It is recommended that you insert and secure one lead at a time.
8. Tighten the dome nut of the liquid tight to secure/seal cable.
9. Replace cover carefully being sure not to crimp any of the cables/leads between cover and enclosure
and tighten screws.

21. Appendix 2, PID Theory and Adjustment
The PID control method allows the MPC Vector to accurately maintain a specific desired setpoint for flow rate from the pump it is connected to.
The PID Control Loop is a widely accepted general purpose control algorithm which is built into the MPC Vector. A PID control loop consists of three components which each have their own specific responsibilities in the control loop; the Proportional, Integral, and Derivative components. Although these mathematical terms are derived from calculus, and are internally implemented as such, the PID can be tuned without using a calculator by simply understanding the roles each of the three components play. Note that if you aren’t interested in a semi-technical discussion of PID Control Loops you can skip ahead to Section 21.3.
21.1 PID Controller Theory:
The basic PID Control Loop consists of an input command, the control system, and feedback (see diagram, following page). The user enters an input flow rate. This command is sent through the control system which
decides what the new motor speed should be. That motor speed command is sent to the pump which then changes the output rate. A flow meter at the output of the pump measures the output flow and feeds the data back to the controller. Based on the feed back the control system adjusts the motor speed and subsequently the flow in an attempt to meet the required set point. This process is repeated continuously bringing the flow rate closer and closer to the target until it eventually settles on the target. In the drawing, both the Requested Flow Rate and Control System are integrated into the MPC Vector controller.

Output

Flow measurement from the flow meter
The function we are controlling is liquid flow from the pump, and the variable being controlled by the MPC Vector is motor speed. This control must be based on some type of feedback, in this case a flow meter measuring liquid flow rate.
Feedback and Error
Feedback is critical in control systems. The feedback lets the controller know the actual flow rate being output by the pump at all times. Utilizing the feedback, the control system is able to determine the error which can be defined as the difference between the expected flow rate and the actual flow rate. The PID controller acts on the error, manipulating the process variable being controlled (in the case of the MPC Vector, motor speed) in order to bring the process closer to the setpoint, thereby eliminating the error.
The PID controller does not act on the actual flow rate being reported by the flow meter, it acts on the error between the actual flow rate, and the desired setpoint, it’s goal being to eliminate the error between the two as much as possible.
Sampling Rate
In the digital world the control loop is run at some base period which is called the sampling rate, Ts. After the initial command is given the control system waits for this period of time and then samples the output, compares it to the set point, and makes motor speed adjustments. After the same period of time expires again, it samples the flow rate again and compares it to the expected flow rate and adjusts. This continues as long as the pump is running. Like many other options for the MPC Vector, this is a configurable setting. The sampling rate of the MPC Vector should be at least twice as fast as the sampling rate of the flow sensor.

21.2 Three Control Components:
The PID controller has three adjustable internal components, all of which contribute to the final output value, they are proportional, integral, and derivative.
Proportional Component
The proportional component of the control system (also known as “gain”) is concerned with the current error (“current” as in time, not electricity). The component is calculated by multiplying the current error by a proportional coefficient, commonly known as Kp or proportional gain. Since the proportional component is only concerned with current error it is able to contribute to initial startup speeds. Think of the proportional gain as the component which gives a jump start to the pump. Typical values of Kp for this application are in the 0.25 -> 0.7 range.
Proportional Part = Kp * error
Integral Component
The integral component of the control system (also known as “reset”) provides a historical memory to the system. This is accomplished by adding the errors into an error summation. The sum of the errors is then multiplied by an integral coefficient, Ki which is also called the integral gain. Because the integral component is a historical component, it can take some time to build “history”. The Integral component is used mainly to force the control to track closer to the desired setpoint, to eliminate any “offset”. Typical values of Ki are in the same range as Kp, 0.25 -> 0.7.
Integral Part = Ki * error sum
Derivative Component
The derivative component (also known as “rate”) provides a predictive element to the system. The derivative component compares the current error and previous error to calculate the approximate change over the last sample period. This is then multiplied by the differential coefficient, Kd which is also called the differential gain. When the flow rate of the pump is rising, the differential component is used to keep it from rising too fast. This is because as you get closer to the flow setpoint, the current error will be smaller than the last error. The differential term can be used to stabilize systems with excessive overshoot, it slows down the response as the setpoint is reached.
Derivative Part = Kd * (error – last error)

21.3 PID Basic Summary, what happens when I…
When the proportional control is increased:
Initial rise time to setpoint gets faster
Overshoot once setpoint is reached tends to increase (gets worse)
Steady-state error can be reduced but will never be eliminated
Settling time (ability to hold setpoint) is not strongly affected
Proportional is used mainly to affect the initial startup of the system, how quickly it reaches the desired setpoint. Too much proportional control will result in overshoot and oscillation, and inability to hold a setpoint over time.
When the integral control is increased:
Initial rise time to setpoint gets faster
Overshoot once setpoint is reached tends to increase (gets worse)
Steady state error is eliminated with the proper setting
Settling time (ability to hold setpoint) is increased (gets worse)
Transient response ( for example to an upset condition) may get worse
Integral is used mainly to tune the system to reach a certain setpoint, to eliminate any offset the might be present, for example the desired flow rate is 5.0 gph, but the system settles and runs at a consistent 5.2 gph. If too much integral control is used, the system can overshoot, not settle, and not react smoothly to transient (temporary) upset events.
When the derivative control is increased:
Stability of the system is increased
Rise time to setpoint is not significantly affected
Overshoot is controlled and decreased with the proper setting
Settling time is decreased and controlled with the proper setting
Steady state operation is not affected significantly
Derivative is used to tune out oscillation of the system around the desired setpoint. Too much derivative control will result in a system that never reaches setpoint, reacts too slowly, or is unstable and will not hold setpoint.
A properly tuned PID loop will:
Reach the desired setpoint in a reasonable amount of time
Maintain operation at or very close to the setpoint with minimal oscillation
React quickly to transient changes or upset conditions

21.4 Putting it all together to run the MPC Vector
The proportional, integral, and differential components are all added together into a command sum which is used to set the motor speed. The motor speed command does have software protection which prevents the motor speed from ever exceeding the max motor speed or from being negative and therefore if the command loop is unstable, no damage can be caused to the drive, motor, or pump. Please be aware though that the
motor could reach maximum speed during tuning and all necessary system precautions should be taken.
Also note that the differential part alone can not be used to start the motor since it depends on previous values. If the previous saved error matches the current error then the differential part will be 0 and therefore the differential part alone will not start the motor reliably. It is possible to eliminate one of the parts by setting the appropriate coefficient to 0 (i.e. if you want a PI only controller set Kd to 0 to eliminate the differential part). However the tuning steps below assume that all 3 parts will be used.
Step 1 – Configure the MPC Vector (reference earlier sections of this IOM for more detail)
1. Make sure that the chosen flow meter is hooked up to the proper location in the MPC Vector.
2. Flow units should be set appropriately in the menu
3. Max flow should be set to at least the max flow achievable by the pump at max speed.
4. Flow sensor type should be set appropriately (digital or analog)
5. Flow calibration should be performed to make sure the MPC Vector flow reading matches flow meter
feedback.
Step 2 – Choosing the test setpoint
In order to tune the PID loop it is necessary to choose a test speed. For most purposes the test flow should be set to approximately 80 – 85% of the max flow. If the test point is too close to the maximum flow, you may not notice the overshoot. If the test point is too low you may have an unstable system at higher flow rates.
Step 3 – Tune the Proportional gain
1. Start with an integral gain of 0 and a derivative gain of 0. The proportional gain should be set to allow
the motor to start reliably.
2. Set the motor to the test setpoint
3. Start with a proportional gain of 0.1
4. Make sure that the integral and differential gains are 0
5. At the main operations mode screen, attempt to start the pump. If the motor starts and settles at a low
speed with minimal flow then the proportional gain is set. If not, increase the gain by 0.05 and try again. Continue until motor start condition is met reliably.
Step 4 – Tune the Integral gain
1. The Integral gain is what will ultimately pull the speed up to the desired setpoint. Note that because
the Integral gain is based on a sum it takes some time for the Integral part to stabilize.
2. Make sure that the proportional gain is set as found above. differential gain is still 0
3. Start with an integral gain of 0.05
4. At the main operations mode screen, start the pump. You should see that the flow is now slowly
building towards the setpoint. Increasing the integral gain will cause the buildup to occur faster. Keep adding 0.05 to the integral gain until you overshoot your setpoint. As an example, if your setpoint is 5 GPM, your gain might go to 5.1 GPM before falling down to 4.9 GPM or so and oscillate for a few seconds.
62
Once you see the oscillation, back the integral gain down by 0.05 – 0.1. Start the pump again and make sure that the flow rate does not overshoot the setpoint significantly.
Note: you may want to use a stopwatch to time how long it takes to get to 80% of the setpoint, especially if you are using the Pulsaguard pump protection. Pulsaguard will stop the pump if the minimum flow is not reached within the timeout limit. In any case the pump should be able to get to at least 90% of the given flow setpoint within 25 seconds.
Step 5 – Tune the derivative gain
The derivative gain is not required under all circumstances. In many cases, a PI controller alone is sufficient to control the pump flow. If derivative gain is added, start with a low setting (0.05 or so) and keep adjusting in
0.05 increments until desired settling time is met.
21.5 Troubleshooting
My flow rate is never reached. How can I fix it?
If the flow rate is never reached you have what is called an over-damped system. Try increasing the Integral gain to help pull the setpoint up higher. Also, make sure your flow rates and units match. If you are trying to set a flow higher than the pump can provide, you’ll never reach it!
My flow goes past the setpoint and back below again and oscillates a long time. How can I fix it?
Some oscillation is natural in many PID controlled systems. To minimize it you need to decrease the Proportional and/or Integral gains to slow the system down a bit.
