PR 0.3 Effective 8/99
 Confirm that you are viewing displays for the correct relay. This is easily done by
disconnecting and reconnecting the network connector.
 If communications can't be established, check for address 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 Setpoints
 Make a copy of Table 4.3 as a worksheet for recording setpoint choices.
 Read Sections 5 and 9 carefully for guidance in selecting setpoints.
 If the MP-3000 is to talk to an older IMPACC system in the IQ2 EN mode, see Section 10 for
setpoint restrictions.
 If desired, PowerNet data communications can be used to download a preconfigured setpoint
record to the relay from a disk file or from a convenient worksheet on the host display.
IMPACC cannot be used to enter setpoints to an MP-3000.
 If PowerNet is not used, enter the setpoints through the front panel in Program mode, using
the Program button behind the security door.
 After setpoints have been entered, exit the program mode by pushing the Program button
again.
 Verify that the settings have been correctly entered using the View SP mode button.
 Reconfirm that the motor nameplate values agree with the corresponding relay setpoints.
 Reconfirm that the ratios of the phase and ground Cts in the gear agree with the PCT and
GCT setpoints of the relay.
CAUTION
The MP-3000 has 154 setpoints, which are easy to confuse. Do not attempt to enter values
without using the appropriate Set Point Record Sheet. Improper operation and/or personal injury
could result if this procedure is not followed.
7.7 Checking contact outputs
DANGER
Be aware of whether control power is applied to the output contacts before testing. Avoid
unexpected operation of the motor contactor or other controlled devices during testing. Personal
injury or damage could result.
 Determine the mode of each of the output relays. See setpoints P12L1 through P12L4.
 If possible and safe, use a live test of the actual wiring or devices operated by the MP-3000
output contacts to verify contact operation and check wiring.
 If contacts are energized, a voltmeter can be used to check. Use an ohmmeter or continuity
checker only on dead, disconnected circuits.
 With MP-3000 power applied, each output relay set for Mode 1 should have its NO contact
open and its NC contact closed.
 Each relay set for Mode 2 should have its NO contact closed, and its NO contact open.
 Enter Program mode. Navigate to Page 13, SP TEST. Setpoints P13L2 to P13 L5 can be
used to set up each of the output relays for test.
 Push the Reset button, as explained in Section 5, to toggle the state of each of the relays in
turn. Check the switching of the output relay, and the energization of controlled circuits if
possible.
 Exit Program mode.
