Calculating with graphs
Proceed as follows:
1. Calculate the maximum current consumption
of the outputs/valves (I
2
).
2. Calculate the lowest voltage to be expected
on the power unit during operation (V
Omin
).
Take into consideration:
•
the inluence of load variation of the power
unit
•
the fluctuations in the primary mains voltage.
3. Read the permitted length of cable in the
table for the relevant cross section.
Example for 1.5 mm
2
:
V
Omin
= 22.8 V, I
2
= 2 A; L
max
= 25 m
