I.L. 17562
PR 0.3 Effective 8/99
Disconnect the discrete input leads, if used, to terminals 8 and 10.
Connect voltmeters between the leads just disconnected from terminals 8 and 10, and
terminal 9, the discrete input common.
Close or jumper the contacts which are read by the discrete inputs, if used.
7.3 Initial checking with ac power to relay
Turn on ac power again. The MP-3000 is now energized.
Check the voltage between MP-3000 terminals 6 and 7. It should be approximately 120 Vac,
regardless of 120V or 240 V supply.
If discrete input 1 is used, verify that 120 Vac is present on the lead disconnected from
terminal 8, measured to terminal 9.
If discrete input 2 is used, verify that 120 Vac is present on the lead disconnected from
terminal 10, measured to terminal 9.
Place the relay in Program mode. Navigate to the SP TEST page.
Page to P13L7, state of discrete input 1. It should report DI 1 OFF.
Page to P13L8, state of discrete input 2. It should report DI 2 OFF.
Check voltage across power terminals of URTD power connector plug removed from J3.
Confirm 120 Vac.
Turn off ac power again. Troubleshoot discrete input and/or URTD wiring if necessary.
Reinstall power plug into J3 of URTD.
Check URTD configuration DIP switches, to insure they are set for the types of RTDs
actually installed in the motor and load equipment. See URTD I.L. 17367 for specifics.
Reconnect the leads disconnected from terminals 8 and 10.
Turn on ac power again.
Recheck P13L7, state of discrete input 1, if used. It should report DI 1 ON.
Recheck P13L8, state of discrete input 2, if used. It should report DI 2 ON.
Turn off ac power again. Troubleshoot discrete input wiring.
Remove jumpers on remote contacts or set to normal state.
Use the MP-3000 discrete input test page indications to test the actual operation of the
contacts, if possible.
7.4 Further checking of the relay with ac power
Apply ac power to the relay and optional URTD.
The MP-3000 will quickly initialize and display its status, usually READY--3, unless the relay
sample has been subjected to an unusual combination of setpoints 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.
If the URTD is connected, push the Monitor mode button and navigate to the MONT RTD
page. If the MONT RTD page cannot be accessed, the URTD module is dead or not
communicating with the relay at all. Troubleshoot communications wiring or optical fiber,
and URTD power.
Check the 11 temperature display lines. Each connected 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 to confirm that the communications network is
connected.
Visit the PowerNet or other host and check the monitoring displays for the particular MP-
3000.
