2.0 Installation, continued
2.5 Programming the PIM
Programmable parameters (with PIM option) are:
Channel 1 Overcurrent Limit: The RMS current level that causes the Output 1 protection
relay to trip after a specified delay (overcurrent tolerance period).
Channel 2 Overcurrent Limit: The RMS current level that causes the Output 2 protection
relay to trip after a specified delay (overcurrent tolerance period).
Retry Delay: The time between each attempt to restart an output in the event of an
overcurrent event.
Retry Limit: The number of times the XM2-300HP will attempt to restart an output
connection. Once the RETRY LIMIT is exceeded, the XM2-300HP will attempt to restart the
output connection every 30 minutes. Set this parameter to “zero” to disable the “automatic
retry” function.
Overcurrent Tolerance Period (1-10 seconds): In the event of an overcurrent episode,
the amount of time an output overcurrent condition is permitted on either output connection.
Once this time expires, the output protection relay disables its output feeder.
Reset Output 1/Reset Output 2: Once fault condition has been corrected, this manually
resets tripped output.
Programming any of the above parameters will reset the “trip/retry” counters.
NOTE:
If the optional PIM is not installed, the values shown on the “PIM PARAMETERS” line of the Smart Display
are “read only”.
