MASTER LINK

LED tester

40

Simple circuit tester for troubleshooting Master Link/Power Link systems. 
Using this tester you can quickly fi nd breaks or poor connections in the 
system. 

Professional tool for troubleshooting 
ML/PL installations. 
Circuit tester for connections/cables 
and sockets.

8053404

ML/PL cable tester

This LED tester consists of two boxes and two Master Link cables. 

The main box connects to the Master Link system. When turned on, the 
main box sends an electric pulse through each individual core in the 
Master Link cable.

The LED box can then be connected to the remaining Master Link 
connections one by one. A range of LEDs will light up as the main box sends 
the pulses through the individual cores. This enables you to easily see if 
there is a circuit in all cores and thus locate the defective link (e.g. junction 
box or wall socket). If an LED is weakly illuminated it means that there is a 
poor connection. There is also an output and input for testing Power Link 
cables.

The illustration shows typical Master Link system connections. We will use 
this system as an example to show how the LED tester tests the Master Link 
cable circuits.
