The MP-3000 is normally set for Mode 2 operation of the TRIP and
ALARM relays.
5.12.2 Setting P12L2, Configure Alarm Relay Output (AL MODE1 or
AL MODE2)
Select Mode 1 or Mode 2 operation of the alarm relay - see 5.12.1
above. The factory default is the fail-safe MODE 2.
5.12.3 Setting P12L3, Configure AUX1 Relay Output (AX1 MOD1 or
AX1 MOD2)
Select Mode 1 or Mode 2 operation of the AUX1 relay - see 5.12.1
above. The factory default is MODE 1.
5.12.4 Setting P12L4, Configure AUX2 Relay Output (AX2 MOD1 or
AX2 MOD2)
Select Mode 1 or Mode 2 operation of the AUX2 relay - see 5.12.1
above. The factory default is MODE 1.
5.12.5 Setting P12L5, Auto or Manual
I2T Reset (MAN I2T or
AUTO I2T)
Select AUTO I2T to set this particular alarm function to automatically
reset when the thermal-model bucket level drops below the alarm
setting P4L2 (I2TA XX). Select MAN
I2T to reset only after the thermal-
model bucket level drops below the alarm setting P4L2 (I2TA XX) and
a manual reset command is given. The RESET command can come
from the front-panel Reset button, from the PowerNet communica-
tions host, or from a remote contact . A remote reset contact, if used,
is connected to one of the digital input channels; and that channel
must be programmed for REM RST (remote reset) or RST DBL (reset
disable).
5.12.6 Setting P12L6, Enable Programming with a Running Motor
(RUN PGM or STOP PGM)
If RUN PGM is selected, the motor may be started and/or run during
programming of the MP-3000 settings. If STOP PGM is selected, the
motor must be stopped in order to enter the PROGRAM mode, and
starting is blocked.
NOTE
IF YOU WANT TO TAKE FULL ADVANTAGE OF THE ARMED/
DISARMED CAPABILITY OF THE MP-3000 AS DESCRIBED IN
P12L18 BELOW, BE SURE TO SET P12L6 TO RUN PGM.
With RUN PGM, if the user reprograms the MP-3000 while the motor
runs, the relay continues to protect with the all the old settings. All
setting changes are stored in a scratchpad area and not immediately
used. Finally, when the reprogramming is finished, the user exits the
PROGRAM mode by pushing the Program button again—see Section
4. Only at this moment does the MP-3000 recalculate its internal
values and put the new settings into effect. Note what happens when
it does so:
• Thermal-model accumulator bucket is dumped and resets to 40
degrees C.
• Any active run delay timers are reset and must start timing again.
• All jogging functions are reset—time between starts, cold starts,
and starts per time limits are all cleared.
• The MP-3000 remembers that it was in the RUN state when the
program mode was exited, and continues that state. The transition
function will not reset, or trigger a reduced-voltage starter to switch
to reduced voltage.
5.12.7 Setting P12L7, Emergency Override Enable (EMRG EN or
EMRG DIS)
Select if the emergency override button is enabled or disabled. If
enabled, an emergency override can be executed by pushing the
Emrg Override button behind the front-panel security door. In any
case, an emergency override can be performed by a remote contact
connected to either of the discrete inputs DI1 or DI2 programmed as
EMG OVR; or via data communications from a PowerNet host. The as-
shipped setting is disabled.
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 RE-
STARTS ALL PROTECTIVE FUNCTIONS OF THE MP-3000. YOU
CAN DAMAGE THE MOTOR. USE ONLY FOR TRUE EMERGEN-
CIES, 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 Setting 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 Setting P12L9, Month (MONTH)
Set the real-time clock month, 1 to 12.
5.12.10 Setting 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 Setting 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 EN-
TERED AS SINGLE DIGITS. WHEN LATER DISPLAYING ANY DATE,
THE YEAR IS ALWAYS PRESENTED AS TWO DIGITS. EXAMPLES:
• 1999: Setting and all displays of date are 99.
• 2000: Setting is 0; all displays of date are then 00.
• 2004: Setting is 4; all displays of date are then 04.
• 2019: Setting and displays are all 19.
