Protection Control

• Overcurrent Trip
• Current in any phase greater than 1.2 x FLA, the
  unit calculates the time to trip
• Separate calculations are performed for cold and
  hot motors
• Once the fault condition is reached, the LM10
  unit will not reset until an appropriate
  cool-down period has elapsed
• Overcurrent function can not be disabled

16
Protection Control
17
Protection Control

• Cool Down Time
• Upon an Overcurrent, Jam or Stall fault, the LM10
  forces a cool-down period before the motor may be
  restarted
• The time to reset is calculated as a function of
  Trip Class and FLA a the time of trip
• While the motor is in the cool-down time delay,
  the PDU status screen will show a number
  decrementing from 99. Once the number reaches 0,
  the motor can be restarted and the READY TO RUN
  message will be displayed

18
Protection Control

• Current Unbalance Trip
• Trips if the phases are unbalanced
• If the average current exceeds the FLA, then the
  average current is used in the calculations
• Programmable trip setting between 2 and 25 FLA
• Time delay settable between 0 and 255 seconds
• 6 current unbalance equates to a 1 voltage
  unbalance
• A 4 voltage unbalance equates to a 24 current
  unbalance and will frequently cause motor damage
• This function can be disabled
• Ground Fault Trip
• Programmable trip setting between 0.4 and 20A
• Time delay settable between 0.5 and 2.5 seconds
• This function can be disabled

19
Protection Control

• Over/Undervoltage Trip
• Maximum minimum trip levels are hard coded into
  LM10
• Undervoltage trip level is 80 (or 96V)
• Overvoltage trip level is 117 (or 140V)
• This function can not be disabled
• Jam Protection
• According to NEMA or IEC MG 1-1998 part 12, page
  21, polyphase motors 600 V or less not exceeding
  500 horsepower shall be capable of withstanding a
  current not less than 1.5 times the full load
  rated current for not less than two minutes when
  the motor is at normal operating temperature.
  For relatively low over-current conditions,
  particularly on higher NEMA Class motors,
  trip times could be considerably longer than 2
  minutes. Therefore, a separate Jam fault is
  available because the standard time overcurrent
  curve may not protect in this range.
• Jam level can be set between 100 and 250 of FLA
• Time delay settable between 0 and 1000 seconds
• This function can be disabled

20
Protection Control

• Stall Protection
• According to NEMA or IEC MG 1-1998 part 12, page
  21, polyphase motors 600 V or less not exceeding
  500 horsepower shall be capable of withstanding
  locked-rotor current (6 times FLA) for not less
  than 12 seconds when the motor is at normal
  operating temperature.
• Cold motor trip times for a 6 FLA fault are
  determined by trip class. For example, a NEMA
  Class 20 motor at 6 FLA would trip in 20
  seconds. A separate Stall fault is available
  which would allow the user to reduce the trip
  time for large overcurrent situations.
• Stall level can be set between 330 and 600 of
  FLA
• Time delay settable between 0 and 30 seconds
• This function can be disabled
• Load Loss Trip
• Load loss is based on watts
• Power Factor calculated is phase relationship
  between voltage and phase C current
• Load loss level can be set between 15 and 85 of
  Full Load
• Time delay settable between 0 and 255 seconds
• This function can be disabled

21
Protection Control

• Auxiliary Sense Failure
• Detects that a LM10 relay contact (RUN1 or RUN2)
  did not open/close according to its command and
  will shut down the relay
• Time delay settable between 0.1 and 25.0 seconds
• This function can be disabled
• Power Loss Autorestart Feature
• Power loss when running
• LM10 will be able to recover from a power loss of
  up to 4 seconds and return to its previous run
  state
• Enabling autorestart allows the unit to restart
  the motor without operator intervention using a
  momentary Run input
• The default condition, Disabled, would require
  the operator to restart the motor after the LM10
  regains power
• Potential safety hazards must be considered and
  the appropriate setup chosen for each individual
  application
• Run 1 to Run 2 or Run 2 to Run 1
• Delay between forward and reverse or between
  speeds

22

• Baud Rate can be 125kbps, 250kbps or 500kbps
• DeviceNet Fault
• If enabled, the LM10 will consider a DeviceNet
  network failure as a fault and operate relay
  outputs and record into history report

Frequently Asked Questions

Some Frequently Asked Questions

• What about Remote IO?
• A wide selection of DeviceNet Remote IO is
  available from PLC manufacturers as well as from
  GE Mebane (MS2000IO). This IO is intended to
  work as part of a PLC/DCS system.
• Does this work with an HMI?
• Yes. You can configure this to work with an HMI
  either via the PLC/DCS controller or via a PC
  based DeviceNet card.
• Does this have ODVA?
• As we come out with firmware revisions, we will
  apply and maintain ODVA.
• On the subject of firmware, can I flash new
  firmware upgrades into the LM10?
• No. The LM10s firmware is stored on a EPROM
  chip and not on flash memory.
• What about cables?
• You can obtain a 3 cable when ordering the
  unit. Other DeviceNet cables can be ordered via
  your local PLC distributor.
• What types of DeviceNet Communications does the
  LM10 support?
• LM10 supports unsolicited DeviceNet messaging,
  and specific values via polled messaging. Please
  consult the manual for specifics.
• Who supports the LM10?
• GE Multilin supports the LM10 just as with all
  GE Multilin Devices. Please contact our Customer
  Support Team
• at 1-800-547-8629. For equipment
  integration considerations, please contact the
  MCC equipment OEM.
• Where can I get information on size, specs,
  mounting, and wiring information?
• All product information (manuals, cut sheets,
  etc.) are available on the web.
