MP-4000 IB02602002E
selected, the MP-4000 still displays all alarms and trips, but the trip
output relay contact remains in its non-tripped state.
For safety purposes when the unit is DISARMED, the MP-4000 scrolls
a warning message - “WARNING MP-4000 WILL BE DISARMED
UPON EXIT OF PROGRAM MODE AND WILL NOT PROTECT THE
MOTOR - ENTER ARMED INTO SETTING TO PROTECT THE MO-
TOR”. The default display reads DISARMED, and the Protection LED
turns off. Any alarm or trip messages on the display alternate with the
word DISARMED.
In the ARMED mode, the MP-4000 works normally.
The DISARMED mode is useful for commissioning a new relay or new
settings on a running motor, when a false trip output would disrupt the
process. The User can commission the MP-4000 in the DISARMED
mode and observe its behavior, noting any trip operations or filling of
the
I2t thermal bucket without suffering the consequence of an unde
-
sired trip. Once the User confirms that the settings are suitable, set the
MP-4000 to ARMED and true protection is enabled
.
NOTICE
ThE alaRM, aUX1, aND aUX2 OUTPUT CONTaCTS all FUNC-
TION NORMally, EVEN WhEN ThE MP-4000 IS DISaRMED.
NOTICE
TO GET ThE FUll USE OF ThE DISaRMED/aRMED CaPaBIlITy
OF ThE MP-4000, BE SURE TO SET P12l6 TO RUN PGM (allOW
ThE MP-4000 TO BE PROGRaMMED WhIlE ThE MOTOR RUNS),
SO ThaT ThE RElay CaN BE aRMED WIThOUT STOPPING ThE
MOTOR.
CaUTION
WhEN DISaRMED FOR MaINTENaNCE REaSONS, ThE MP-4000
IS NOT PROTECTING ThE MOTOR. aFTER PROPER OPERaTION
IS CONFIRMED, BE SURE TO SET TO aRMED. BE WaTChFUl aT
all TIMES FOR ThE DISaRMED MESSaGE ON ThE DISPlay.
5.13 Page 13, SP TEST, Settings P13l1 to P13l8
Page 13 is used to test the MP-4000.
5.13.1 Setting P13l1, Operating Mode (3 PhaSE or 1 PhaSE)
This function allows the MP-4000 to be bench-tested using a single-
phase current source (1 PHASE) if a three-phase source is unavailable
at the test bench. The phase unbalance functions cannot be tested
in 1 PHASE mode. For three-phase testing and all normal operation,
select the three-phase mode (3 PHASE).
CaUTION
IN SERVICE, ThE MP-4000 DISPlayS REaDy - 3 WhEN REaDy
TO STaRT IN ThE ThREE-PhaSE MODE. IF IT DISPlayS REaDy
- 1, ThE USER IS WaRNED ThaT ThE RElay IS IN ThE SINGlE-
PhaSE TEST MODE, WhICh IS NOT SUITaBlE FOR PROTEC-
TION OF a REal ThREE-PhaSE MOTOR.
5.13.2 Setting P13l2, Trip Relay Test (TRP ENER or TRP DENR)
P13L2 permits the User to directly energize or de-energize the trip
relay for testing purposes. To use this function:
1. Stop the motor first. The test is blocked if the motor is running.
2. Determine whether the MP-4000 trip relay is configured for
MODE 1 or MODE 2 operation. Refer to Setting P12L1 in Sub
-
section 5.12.1.
3. If MODE 1, the trip relay is normally de-energized. Set up for the
test by selecting TRP ENER.
4. If MODE 2, the trip relay is normally energized. Set up for the
test by selecting TRP DENR.
5. Press the Reset button to test the relay. The Trip LED also lights.
Release the button to revert to the prior output state.
5.13.3 Setting P13l3, alarm Relay Test (alM ENER or
alM DENR)
P13L3 lets the User directly energize or de-energize the alarm relay
for testing purposes. Use it in the same way as the trip relay test.
Check the Alarm relay MODE Setting P12L2. Unlike the trip output,
this output can be tested with the motor running.
5.13.4 Setting P13l4, aUX1 Relay Test (aX1 ENER or aX1 DENR)
P13L4 permits the User to directly energize or de-energize the AUX1
relay for testing purposes. Use it in the same way as the trip relay
test. Check the AUX1 relay MODE Setting P12L3. Unlike the trip
output, this output can be tested with the motor running.
5.13.5 Setting P13l5, aUX2 Relay Test (aX2 ENER or aX2 DENR)
Lets the User directly energize or de-energize the AUX2 relay for test-
ing purposes. Use it in the same way as the trip relay test. Check the
AUX2 relay MODE Setting P12L4. Unlike the trip output, this output
can be tested with the motor running.
5.13.6 Setting P13l6, Force analog Output Current Value
(aOUT 4, aOUT 12, or aOUT 20)
To test the analog output, first select the value to force (either 4, 12,
or 20 mA). When ready to test, push and hold the Reset button to
observe the forced output value. When the Reset button is released,
the analog output returns to normal operation.
5.13.7 Setting P13l7, State of Discrete Input 1 (DI1 ON or OFF)
P13L7 is read only - it is not a setting. Use this to determine if Dis-
crete Input 1 is ON (energized) or OFF.
5.13.8 Setting P13l8, State of Discrete Input 2 (DI2 ON or OFF)
P13L8 is read only - it is not a setting. Use this to determine if Dis-
crete Input 2 is ON (energized) or OFF.
5.14 Page 14, SP RESET, Settings P14l1 to P14l4
Page 14 is used to reset or clear the accumulated history mode statis
-
tics on the History pages:
Press the line button on the History page to clear.
Press either Value button to get the PUSH RST display.
Press the Reset pushbutton to clear the History page.
To escape without clearing, don’t push Reset. Use a Value
button to change from PUSH RST back to [History Page
Name] RST, then navigate elsewhere or exit the Program
Mode.
