WARNING
Be sure to return setpoint P13L1 to 3 PHASE before returning the relay to service. All protection
functions that check phase balance or sequence are disabled in 1 PHASE test mode. Seeing the
display READY --1 in the Motor State mode when the motor is stopped is a warning that the
setpoint is at 1 PHASE. The correct display is READY --3.
11.5 Testing the Trip Relay — Stop the motor. The test is blocked if the motor is running.
Enter Program mode, go to test setpoint P13L2. The trip relay contacts (terminals 11 through 13)
can be monitored for proper operation, or observe the controlled-circuit operation. Refer to
Figure 6.5 for rear panel terminal layout. To use this function:
• Determine whether the MP-3000 trip relay is configured for MODE 1 or MODE 2 operation -
see SYSTEM Page Setpoint P12L1.
• If MODE1, the trip relay is normally de-energized. Set up for the test by selecting TRP
ENER in P13L2.
• If MODE 2, the trip relay is normally energized. Set up for the test by selecting TRP DENR
in P13L2.
• Push the Reset button to test the relay. The Trip LED also lights. Release the button to
revert to the prior output state.
11.6 Testing the Alarm Relay — Use setpoint P13L3. The procedure is the same as for the trip
relay test. Press the Reset pushbutton to light the Alarm LED and activate the alarm contacts
(terminals 17 through 19). If the MP-3000 is set for RUN PGM, this output can be tested while
the motor runs.
11.7 Testing the AUX1 Relay — Use setpoint P13L4. The procedure is the same as for the trip
relay test. Press the Reset pushbutton to light the Aux 1 LED and activate the Aux 1 contacts
(terminals 14 through 16). If the MP-3000 is set for RUN PGM, this output can be tested while
the motor runs.
11.8 Testing the AUX2 Relay — Use setpoint P13L5. The procedure is the same as for the trip
relay test. Press the Reset pushbutton to light the Aux 2 LED and activate the Aux 2 contacts
(terminals 1 through 3). If the MP-3000 is set for RUN PGM, this output can be tested while the
motor runs.
11.9 Testing the Analog Output — To test the 4-20 mA analog transducer output at
terminals 24 and 25, use P13L6. Set the test output current level to be 4, 12, or 20 mA. Press
the Reset button to force the selected test output current; release to return to the normal
measurement-driven output.
11.10 Checking Discrete Input 1 — Use P13L7 to see if discrete input 1 is either on or off.
Apply or remove 120 Vac to check both states.
11.11 Checking Discrete Input 2 — Use P13L8 to see if discrete input 2 is either on or off.
Apply or remove 120 Vac to check both states.
