Eaton EMR-3MP0 - Motor Start Recorder; Manage Start Records

5.5 Motor Start Recorder
The Motor Start Recorder logs information during a motor start-up. These records are
stored in a fail-safe manner and the capacity allows for recording up to 5 start-ups. After 5
start-ups, every following start-up overwrites the recording of the oldest one (“First in First
out” principle).
Every recording consists of a summary of information and recorded analog trends.
However, the exact set of data is dependent on the ordered device variant. The summary
data can be accessed using PowerPort-E or via the front panel interface of the EMR-3MP0.
This feature provides information recorded at the time of each start of the motor such as:
• Date of the motor start event
•
Record number
• IA max RMS, IB max RMS, IC max RMS, IX max RMS – Maximum RMS phase current
of the respective phase
• Unbalance max – Maximum current unbalance during the motor start-up
• I avg – Average current of all three phases at the time of the start-to-run transition
• Speed – The motor nominal speed (1 or 2)
•
Time (duration) values:
◦ TSTI – The time that elapses from the start until the current value drops below
the set start-up threshold
◦ TSTR – The time that elapses from the start until the motor is running, or – in
case of an incomplete start sequence – until trip
• I2T used – Thermal capacity used, speci󰊎ed as percentage of the maximum thermal
capacity
•
Start success – This is set to 1 if the motor start has been successful (and equals 0
otherwise).
PowerPort-E allows for storing the summary information as text 󰊎les, or have them
printed out.
The analog trends can be viewed using the QualityManager software. Examples for
recorded analog trends are:
• Phase current values
• Current unbalance
•
Thermal capacity
• Temperatures (in case an RTD box is 󰊎tted)

The start recorder data can be downloaded by means of PowerPort-E from the device.
