  • Page 3: Introduction

    Page 3 I.L. 17562 SECTION 1. INTRODUCTION 1.0 General The MP-3000 is an advanced microprocessor-based motor protection relay that is easy to set up and use. It monitors, controls and protects motors against overload, thermal damage to rotor or stator, electrical faults, and excessive starting, and many process equipment failures. Advanced algorithms and thermal models give safe operation over a wide range of conditions.

    Page 7 I.L. 17562 SECTION 2. PRODUCT OVERVIEW 2.0 General Overview The MP-3000 Motor Protection Relay is available in either a fixed mount, semi-flush case or in a semi-flush Quick Release drawout case. Both housings are compact and fit a standard IQ cutout. The optional Quick Release drawout case features 2-stage contact disconnects and self-shorting Ct circuit terminal blocks.
  • Page 8 I.L. 17562 Page 8 The relay samples the current waveforms 36 times per cycle providing accurate measurements of the positive and negative sequence currents, as well as harmonic components which add to rotor and stator heating. The negative sequence component of current causes far greater heating effect on the rotor and has a greater impact on the thermal model in the relay, as compared to the balanced or positive-sequence component.
  • Page 9 Page 9 I.L. 17562 2.2 Motor Starting and Control Functions The MP-3000 Motor Protection relay includes logic to control the number of starts that can occur on the motor in a given time period for cold and hot motor conditions. Settable timers are provided to control the time between starts and to restart a motor after a stop.
  • Page 10 I.L. 17562 Page 10 2.2.7 Motor Starting Profile The MP-3000 records the average current versus time for the last four starting cycles. This information is available via the communications port. PowerNet host plots the motor current versus the motor cold-start protection curve as in Figure 2.1. 2.3 User Interface The MP-3000 Motor Protection Relay has a user-friendly interface that makes it easy to retrieve important information or to make setting changes.

Application and Settings, for a full understanding of the setpoints and the relay functions they control. This Section summarizes the functions of all of the setpoints.
  • Page 47 Page 47 I.L. 17562 Most of the following setpoints can be viewed by users without access to the Program button behind the front-panel security door. Use the View Settings display mode button. Note that certain setpoints without logical display values are not visible in the View Setpoints mode.

For a 1 ampere Ct set: For optimum metering accuracy at low loads, the Ct should deliver between 0.7 and 0.8 amperes at 100 percent FLA. Attempt to achieve 0.75 A. For reliable motor protection, the Ct should deliver between 0.5 and 0.8 amperes at 100 percent FLA.
  • Page 50 I.L. 17562 Page 50 Ground fault protection by residual connection of phase Cts is possible, but doesn't give high sensitivity. See Section 9.1.10. 5.1.7 Setpoint P1L7, Frequency (FREQ) — Sets the MP-3000 for either a 60 Hz or 50 Hz ac supply frequency.

    Page 67 I.L. 17562 SECTION 6. INSTALLATION AND WIRING 6.1 Mounting — The following subparagraphs describe the mounting of the MP-3000 relay, as well as its optional URTD module and PONI Communications module. 6.1.1 Mounting the MP-3000 — Mount the unit vertically on a flat panel. The location should be as free as possible of water, chemicals, dust, and excessive heat and vibration.
  • Page 68 I.L. 17562 Page 68 The PONI, if used, is always mounted on the back of the MP-3000. If no URTD is mounted there, use the mounting bracket supplied with the MP-3000 as shown in Figure 6.3. The bracket gives a convenient space to run ct wires underneath the PONI to the adjacent Ct terminal block. If a URTD is mounted on the back of the MP-3000, the PONI piggybacks directly to the URTD module as shown.

Use it as a checklist to reduce the chance of skipping an item. DANGER Only qualified personnel familiar with the MP-3000, the motor starter, and its associated mechanical equipment, should perform these startup procedures.
  • Page 82 I.L. 17562 Page 82 Disconnect the discrete input leads, if used, to terminals 8 and 10. Connect voltmeters between the leads just disconnected from terminals 8 and 10, and terminal 9, the discrete input common. Close or jumper the contacts which are read by the discrete inputs, if used. 7.3 Initial checking with ac power to relay Turn on ac power again.
  • Page 83 Page 83 I.L. 17562 Confirm that you are viewing displays for the correct relay. This is easily done by disconnecting and reconnecting the network connector. If communications can't be established, check for address conflicts on the network (multiple devices set to the same address) or incorrect setting of the address switches on the PONI. 7.6 Entering Relay Setpoints Make a copy of Table 4.3 as a worksheet for recording setpoint choices.
  • Page 84 I.L. 17562 Page 84 DANGER The contactor control circuit is to be reconnected. At this time the motor associated with the application can be started. It is important to ensure that all safety precautions associated with rotating equipment and the associated driven mechanism be taken. Failure to do so can result in serious or fatal injury and/or equipment damage.

The positive sequence phasors in phases B and C have the same magnitude as the phase A positive sequence phasor, but lag the phase A component by exactly 120 and 240 degrees respectively. This balanced set of phasors drives the motor's useful work.

APPLICATIONS AND SETTINGS 9.0 General — This section is a supplement to Section 5, giving more engineering and application guidance for particular functions and setpoints. Use this data in conjunction with Section 5 and Table 4.3, to develop setpoints for the MP-3000, as well as making appropriate wiring design.

The trip contact blocks motor restarting until the temperature, as reflected in the thermal accumulator bucket level, cools below the alarm level setpoint I2TA, P4L2. NOTE If stator RTDs are not used and the ambient may rise above 40 degrees C, the ultimate trip current should be set below that indicated by the nameplate service factor to avoid stator insulation damage or loss of life.
  • Page 92 I.L. 17562 Page 92 Note that, for now, we assume that the three phase currents are balanced and have proper 120 degree phase relationship (i.e., only positive sequence current). If negative sequence current reflecting unbalance is present, the MP-3000 gives much heavier weighting to the heating effect of these currents, and tripping will occur sooner than expected from balanced-current curves.

Figure 9.5 shows the impact of a stator RTD measurement. Look at the time period after 60 seconds (near the top).

The contactor is energized by the operator or process control system through a normal two-wire or three-wire motor control scheme, external to the MP-3000.
