5.5.2.3 EOL3 Detection

● EOL Short-circuit below is the threshold for the short-circuit detection in EOL

mode. If the resistance drops below this value, a short-circuit error is detected.

● Dependent on the loudspeakerline impedance, 100 ohms is a good start.

Fig. 21: EOL3 Detection

1. Enable the 'En' flag for each zone you want to monitor.

2. Under 'Pilot RMS', set the 'Value' and 'Tolerance' to a value of between

12…20.

– 'Value' = 17 and 'Tolerance' = 6 provide a good starting point.

– If optimization is required, increase the values.

3. Set 'EOL3V1.0' under 'Type'.

4. Enter the addresses of the modules that are connected to the specified

speaker line.

– Enter the 'From'…'To' values under 'EOL ID Range' as shown in the

example below.

9…9

Only the module with ID 9 is connected to the line.

9…14

Entering a second number that is different from the first defines a range

so that a sweep is started on the line.

5.5.2.4 Monitoring of the return line

For Digital audio matrix (4/4/4)

Fig. 22: Monitoring of the return line

1. Enable the 'En' flag for each zone you want to monitor.

2. Enable the 'Return line available' flag.

3. Enter a value in the 'Pilot RMS [V]' and 'Tolerance' fields.

 If the measured voltage is outside the specified range, the system will raise a

'NO_PILOT_SIGNAL' error.
