7.4.1 System with one transmitter

There are two ways to determine the delay switch positions:

– Measuring the cable lengths

– Using a delay measuring tool

Both methods are described in the next sections.

Determining delay switch positions by measuring the cable lengths

Use the following procedure to determine the delay switch position based on cable lengths:

1. Look up the cable signal delay per meter of the used cable. The manufacturer specifies

this factor.

2. Measure the lengths of the cables between the transmitter and each radiator.

3. Multiply the lengths of the cables between the transmitter and each radiator with the

cable signal delay per meter. These are the cable signal delays for each radiator.

4. Determine the maximum signal delay.

5. Calculate for each radiator the signal delay difference with the maximum signal delay.

6. Divide the signal delay difference by 33. The rounded off figure is the signal delay switch

position for that radiator.

7. Add delay switch positions for radiators under a balcony, if applicable (see section

7.4.3 ).

8. Set the delay switches to the calculated switch positions.

Figure 7.3 and Table 7.1 illustrate the calculation of the cable signal delay.

NOTICE!

The delay switch calculation tool eases the calculation of the delay switch positions.

NOTICE!

For systems with a cable length difference of more than 50 meters, it is recommended to use

a measurement tool to determine the delay differences in order to calculate the delay switch

positions.
