Example of using the diagram
Two remote EVAC-NL indicators, one with 20 zones, the other with 30 zones, are
supplied by the periphery board of the same ↑ station.
20 pin
Figure 138: Wiring example for calculating the cable resistance
Number of zones via the same supply cable: 50 (20 from panel 1 and 30 from
panel 2)
According to the diagram, this results in the following values for the EVAC-NL
mimic display driver:
●
Maximum cable resistance R' is 10 Ω (curve 1)
●
Maximum current is 0.85 A (curve 4)
In the same way, this would result in the following for a remote EVAC-NL indicator:
●
Maximum cable resistance R' is 22 Ω (curve 2)
●
Maximum current is 0.4 A (curve 3)
