Turn off ac power again. Troubleshoot the discrete input

and/or URTD wiring, if necessary.
Reinstall the power plug into J3 of the URTD.
10.
Check the URTD configuration DIP switches, to insure they
11.
are set for the types of RTDs actually installed in the motor
and load equipment. See URTD I.L. 17367 for specifics.
12. Reconnect the leads disconnected from terminals 8 and 10
Turn on ac power again.
13.
Recheck P13L7, the state of discrete input 1, if used. It
14.
should report DI 1 ON.
Recheck P13L8, the state of discrete input 2, if used. It
15.
should report DI 2 ON.
Turn off ac power again. Troubleshoot the discrete input

wiring.
Remove the jumpers on the remote contacts or set them to
17.
the normal state.
Use the MP-4000 discrete input test page indications to test
18.
the actual operation of the contacts, if possible.
7.4 Further Checking of the Relay with aC Power
1. Apply ac power to the relay and optional URTD.
The MP-4000 quickly initializes and displays its status, usu-
2.
ally READY - 3, unless the relay sample has been subjected
to an unusual combination of settings and recent prior
service or testing. Usually, one or more output relays can be
heard to click as they are energized.
The Protection LED on the faceplate should light.
3.
If the URTD is connected, press the Monitor mode button
4.
and navigate to the MONT RTD page. If the MONT RTD
page cannot be accessed, the URTD module is dead or is
not communicating with the relay at all. Troubleshoot the
communications wiring or optical fiber as well as the URTD
power.
Check the 11 temperature display lines. Each connected
5.
RTD should display an appropriate value (e.g.: 25 at room
temperature). Non-functioning or unused RTD inputs display
a — character for a value.
7.5 Checking Data Communications
If the relay is equipped with a PONI, check it to confirm that
1.
the communications network is connected.
2. Visit the PowerNet or other host and check the monitoring
displays for the particular MP-4000.
Confirm that the displays in view are for the correct relay.
3.
This is easily done by disconnecting and reconnecting the
network connector.
If communications can not be established, check for address
4.
conflicts on the network (multiple devices set to the same
address) or incorrect setting of the address switches on the
PONI.

7.6 Entering Relay Settings
1. Make a copy of Table 4.3 as a worksheet for recording set-
ting choices.
Read Sections 5 and 9 carefully for guidance in selecting
2.
settings.
If desired, PowerNet or PowerPort data communications
3.
can be used to download a pre-configured setting record to
the relay from a disk file or from a convenient worksheet on
the host display. IMPACC cannot be used to enter settings
to an MP-4000.
If electronic communications are not used, enter the settings
4.
through the front panel in Program mode, using the Prog
button behind the security door.
5. After settings have been entered, exit the program mode by
pressing the Program button again.
Verify that the settings have been correctly entered using
6.
the View SP mode button.
Reconfirm that the motor nameplate values agree with the
7.
corresponding relay settings.
Reconfirm that the ratios of the phase and ground CTs in the
8.
gear agree with the PCT and GCT settings of the relay.

Determine the mode of each of the output relays. Look at

settings P12L1 through P12L4.
If possible and safe, use a live test of the actual wiring or

devices operated by the MP-4000 output contacts to verify
contact operation and check wiring.
A voltmeter can be used to check energized contacts. Use

an ohmmeter or continuity checker only on dead, discon-
nected circuits.
With MP-4000 power applied, each output relay set for

closed, and its NC contact open.
6. Enter the Program mode. Navigate to Page 13, SP TEST.
Settings P13L2 to P13 L5 can be used to set up each of the
output relays for test.
