MAINTENANCE

3.1 TEST EQUIPMENT

The following items are necessary to carry out maintenance of the systems:

A multimeter with small test probes, to measure the various test voltages and to test the continuity
of wiring between the main equipment and stations.

(ii) A programming console commonly called TPU-AN, Test and Programming Unit for AN-61 6

Business System. This is equipped with a programming button which places the unit into
“programme” mode, thus enabling verification and/or reprogramming of site-dependant system
data.

(iii) An AMP-Champ connector insertion tool, which is used to terminate the AMP-Champ connector.

 Normal maintenance tools, i.e. Buttinski, Long-nose pliers, Angle Cutters, and both Phillips and flat

blade type screwdrivers.

3.2 TEST POINTS

3.2.1 Power Supply

There are six DC voltages supplied for these systems:

The supply voltages are accessed by pulling out the power supply unit from the main equipment cabinet
and disconnecting the 12-pin power plug from the backplane.

Measure the voltages across the plug pins as shown on table 3.2.1 

 Figure 3.2.1 shows the pin locations

on the plug.
