Emergency Override allows a panic restart of a tripped motor without completely disabling
protection. When the override request is received, the thermal-model accumulator bucket is
drained to its initial level of 40 degrees C. Jogging limit counters and timing, including
antibackspin timing, are reset. Cold starts are fully restored.
The motor protection is now in the state it would be in if the motor had been standing for a long
time prior to the moment of the override. This will allow an immediate restart of the motor. The
override can also delay an impending thermal trip of a running motor. The emergency override
action is counted in the history record, and noted with its time tag in the logbook record.
CAUTION
The EMERGENCY OVERRIDE function clears and restarts all protective functions of the MP-
3000. You can damage the motor. Use only for true emergencies, when you are aware of what
caused the trip. Override lets you risk motor damage to avoid an even more dangerous process
situation caused by the tripping of the motor.
5.12.8 Setpoint P12L8, Set Real Time Clock Display (12 HOUR or 24 HOUR) — Select the
time display to be the 12 hour format (with AM or PM) or the 24 hour (military time or
international time) format.
5.12.9 Setpoint P12L9, Month (MONTH) — Set the real-time clock month, 1 to 12.
5.12.10 Setpoint P12L10, Day (DAY) — Set the real-time clock day of the month. The MP-
3000 tracks leap years to the year 2100.
5.12.11 Setpoint P12L11, Year (YEAR) — Set the real-time clock year.
NOTE
MP-3000 timekeeping is Y2K compliant. When setting only, the year values for the first decade
are entered as single digits. When later displaying any date, the year is always presented as two
digits. Examples:
•
1999: Setpoint and all displays of date are 99.
•
2000: Setpoint is 0; all displays of date are then 00.
•
2004: Setpoint is 4; all displays of date are then 04.
•
2019: Setpoint and displays are all 19.
5.12.12 Setpoint P12L12 , Hour (HOUR) — Set the real-time clock hour (0 to 23) Use 13 to 23
for setting even if the 12-hour AM/PM mode was selected above for display.
5.12.13 Setpoint P12L13, Minute (MIN) — Set the real-time clock minute. The minute does not
update on its own while the relay is in program mode, so make this the last setting to adjust
before exiting.
NOTE
There is no setpoint for seconds. The clock seconds are set to zero when the user exits the
program mode. To synchronize the seconds, set the minute value ahead, and exit (hit the
program button) as the next minute begins.
