Make sure the connection between the equipment and the system has been carried out
correctly according to section 4.2. To debug the fault, disconnect both ends of the two bus cables
connected between the system and the equipment, and measure between each of the cable
terminals with a multimeter on the scale k . If the measurement result is 0, the line is short-
Ω
circuited, and should be checked or replaced. If the result is 1, it means that it is correct.
Do a RESET (the equipment will have to be reconfigured). To do so, push simultaneously
the "ACK", "RST" and "TEST" keys for 5 seconds. The equipment will restart. Set the equipment
address according to 4.2
If none of the above works, remove the equipment from the bus and contact the
