PME-500-TR

Basic Performance Test

An EuroSMC®training paper

INTRODUCTION

The PME-500-TR integrates measurement instruments and a number of test automation devices in a single piece

of equipment designed for the evaluation and condition assessment of three-phase circuit breakers. This

document describes a few simple procedures to ensure the correct operation of all the functions involved in the

evaluation of a circuit breaker without doing an actual test. These procedures may help the user diagnose

common problems quickly and, in most cases, provide a permanent solution with no need to return the

equipment to a service centre. Measurement accuracy, however, falls beyond the scope of this guide, as it

requires specific resources, knowledge, and environmental conditions only guaranteed by EuroSMC and

authorized calibration laboratories.

We recommend you to conduct the following tests before contacting EuroSMC or your local service

representative if you face trouble while using your PME-500-TR.

Checking the coil control system

The coil control system consists basically of two solid-state on/off switches opening or closing the circuit that

supplies power to the circuit breaker’s operation coils. These ‘switches’ are sensitive to polarity, and can be

operated manually by pressing the ‘open’ or ‘close’ buttons in the PME-500-TR’s TEST menu. To check the

coil control system for proper operation, you will need a small lamp, a suitable battery, a short section of

conductor and a few simple steps:

1. Plug the coil control cable (black / blue leads

labelled “C” and “T”) into the Coil Control

multi-connector.

2. Open the SET menu and set Duration to 1000

ms. for both Close and Open.

3. Connect the terminal labelled as “C” at the end

of one of the blue leads to the battery’s positive.

4. Connect the other terminal labelled as “C”

(black lead) to one pole of the lamp.

5. Complete the circuit by connecting the other

pole of the lamp to the battery’s negative with

your section of conductor. The lamp should

NOT be lit.

6. Open the TEST menu and press the Manual

Close button while observing the red On LED

on the right of the black/green Close connectors.

This LED and the connected lamp should be

simultaneously lit for one second.

OPEN CLOSE

7. Repeat steps 2-6, this time using the “T”

terminals and pressing the Manual Open button while observing the red On LED on the right of the

black/green Open connectors.

If you obtain different results check your cables for continuity and refer to the troubleshooting guide in the

user’s manual. There are internal fuses that might be blown.

Checking the main contact state detection

The PME-500-TR determines the state (open or closed) of the circuit breaker’s contacts by measuring the

resistance between both sides. You can easily check your unit for proper recognition of open or close states by

following these steps:

1. Plug the main contact timing cable into the Contacts multi-connector. This lead groups six leads with

black / red 4-mm terminal pairs labelled C1, C2, and C3 respectively.

2. Open the TEST screen and touch underneath the two lower

corners of the START/STOP button. The Factory

Measurements screen should be displayed. The signature “O-

O-O” should be visible on the lower left, indicating that C1,

C2 and C3 pairs are disconnected (Open).

3. Interconnect the black and red terminals labelled as C1. The

signature should change to “C-O-O” after a short while. Do

not undo the connection yet.

4. After doing the same with the C2 terminals, the signature

should change to “C-C-O”

5. Finish with the C3 terminals to display “C-C-C” and then undo

the three connections successively while observing the display

as it returns to “O-O-O”

If you obtain different results, check your test leads for continuity and

refer to the troubleshooting guide in the user’s manual. There are internal fuses that might be blown.

Checking the contact resistance measurement

The PME-500-TR uses the four-wire method (Kelvin connection) to measure the resistance of the three closed

poles in the circuit breaker. This is the simplest way to check the integrity of the resistance measurement system

for the three phases:

1. Ensure that the PME-500-TR’s battery holds some charge or leave the unit switched off and connected

to an AC outlet to re-charge for at least 15 minutes. This test takes the power from the battery, even if

the unit is connected to a mains AC outlet.

2. Plug the main contact timing cable into the

Contact multi-connector in the PME-500-TR

(you may have it already connected after

performing the procedure above) C1

3. Plug the voltage measurement cable into the

Res. Measure multi-connector.

4. Interconnect the black and red terminals labelled

as C1 at the free end of the Contact timing cable

as shown in the figure.

5. Do the same with pairs C2 and C3

6. Do the same with pairs R1, R2, and R3 at the

free end of the Res. Measure cable.

R1 R1

7. Open the TEST menu and press the START

button on the right. The PME-500-TR will

measure the contact resistance of the three

‘poles’ and a “Test finished” message should be

displayed after a short while.

8. Exit the TEST menu and navigate the RES tab for the measured resistance values. The three values

should be exactly ZERO.

If you obtain different results, check the continuity of your test leads, double-check the connections as described

above and repeat the test. If problems persist, refer to the troubleshooting section in the user’s manual. There are

internal fuses that might be blown.

Checking the Auxiliary inputs

The Aux1 and Aux2 inputs can be used individually as timing inputs for other contacts in the circuit breaker

(typically the coil or the signalling contacts) or as triggering inputs to synchronize the PME-500-TR to an

external start signal when a remotely controlled test is required. To check these inputs for integrity and proper

operation, do the following:

©EuroSMC, S.A. 2005 – PME-500-TR Basic Performance Test Procedures Page 3 of 4

1. Plug the Aux input cable into the Auxiliary Inputs multi-connector.

2. Open the SET menu and program a simple

CLOSE for Operation.

3. Set Duration to 2000 ms for the Close command.

4. Set the Trigger option to Aux1(ON).

5. Open the TEST screen and press the START /

STOP button. A message “Waiting for trigger”

should be displayed at the bottom of the screen.

6. Identify the two 4-mm terminals labelled as A1

at the free end of the Auxiliary Input test cable.

7. While observing the red Close LED on the right

of the black / green Close coil control inputs, put

the two A1 terminals in contact momentarily as

shown in the figure. The Close LED should turn

on for 2 seconds. To repeat, just press the

START / STOP button and try again.

8. Repeat steps 4-7, this time choosing Aux2(ON)

in step 4 and using the terminals labelled as A2.

9. Exit the TEST menu

10. Interconnect both A1 terminals by inserting one

into the back of the other. Do the same with both

A2 leads.

11. Enter the SET menu and set the Trigger option

to Aux1(OFF).

12. Open the TEST screen and press the START /

STOP button. A message “Waiting for trigger”

should be displayed at the bottom of the screen.

13. While observing the red Close LED on the right of the black/green Close coil control inputs, undo the

connection of the two A1 terminals. The Close LED should turn on for 2 seconds. To repeat, re-connect

the terminals, press the START / STOP button and try again.

14. Repeat steps 11-13, this time choosing Aux2(OFF) for Trigger in the SET menu and disconnecting the

terminals labelled as A2 in step 13.

NOTE

Restore your normal settings and check the unit’s date/time for proper adjustment before putting the PME-500-TR back into the transport bag
