Energizing the MCC

DANGER
Hazard of Electric Shock, Explosion, or Arc Flash
  • Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E, NOM-029-STPS, CSA Z462, or local equivalent.
  • This equipment must only be installed and serviced by qualified electrical personnel.
  • Turn off all power supplying this equipment before working on or inside equipment.
  • Always use a properly rated voltage sensing device to confirm power is off.
  • Replace all devices, doors, and covers before turning on power to this equipment.
  • Review the “Pre-operation Checklists” beginning on Pre-operation Checklists, and verify that all items check out.
Failure to follow these instructions will result in death or serious injury.

To energize the MCC:

  1. Review the Pre-operation Checklists before energizing.

  2. Turn off all downstream loads, including distribution equipment and other devices that are remote from the MCC.

  3. Verify that all barriers, doors, and covers are closed before energizing the equipment.

  4. Energize the equipment in sequence, starting with the main, the feeder units next, and then the motor starter units.

  5. With all barriers in place and all unit doors closed and latched, turn on the units with a firm, positive motion.

  6. After all disconnect devices are closed, you may energize loads such as lighting circuits, starters, contactors, heaters, and motors.

DANGER
HAZARd of electric shock, explosion, or Arc Flash
  • Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E, NOM-029-STPS, CSA Z462, or local equivalent.
  • Turn off all power supplying this equipment before working on or inside the Motor Control Center.
  • Use a properly rated voltage sensing device to confirm that all power is off. Control units must be de-energized before performing maintenance on the MCC.
  • The unit disconnect switch must be locked in the off position before working on equipment.
Failure to follow these instructions will result in death or serious injury.

Local programming can be used for MotorLogic Plus setpoint programming and detected error readout purposes:

  1. Verify that the display is unlocked (the default setting) and disconnect all power.

  2. Turn off all power supplying this equipment before working on or inside the equipment and follow lockout/tagout procedures. Always use a properly rated voltage sensing device to confirm the power is off.

  3. Connect a nine V supply to the “P” and “G” terminals using the supplied connector, Schneider Electric PN 80445-519-50 (see MotorLogic Plus Communication Module Terminals).

  4. Turn the “Mode Select” switch to the parameter you are programming. Refer to Schneider Electric instruction bulletin 30072-013-98 (see iMCC-related Literature) for a list of parameters.

  5. Press and hold the “Reset/Program” button.

    NOTE: The display does not illuminate for local programming if the “Mode Select” switch is in the “Run” position.

  6. Turn the “Display/Program” dial to the desired setting as shown on the LED display.

  7. Release the “Reset/Program” button.

  8. Turn the “Mode Select” switch back to the “Run” position.

  9. Disconnect the nine V supply and its connector.

Messages are displayed on the three-digit LED display when harmful conditions are detected. Local Message Display contains a list of the message codes and their definitions.

MotorLogic Plus Remote Programming

Remote programming can be used for setpoint programming and data acquisition purposes. Follow the steps below to remotely configure the MotorLogic Plus overload. (See Command Line Codes for a description of the command line codes referenced in the steps.)

  1. Stop the overload by sending code “02H” to the command register (C6H).

  2. If network programming has not been enabled, send code “05H” to the command register.

  3. Program the appropriate parameter. See MotorLogic Plus Address Descriptions (Read only, all registers are 16-bit words) for a register map with a list of parameters. For more detailed information, refer to Schneider Electric instruction bulletin 30072-013-102. See Read-Only Registers and Read/Write Registers to determine the location and addressing of parameters within the MotorLogic Plus register map.

  4. Restart the overload by using code “01H.”
