3. Installation
PLEASE NOTE
Please note that with common voltage supply
for pin 1 (electronic components and inputs)
and pin 2 (outputs/valves), the lower tolerance
of ± 10 % for both circuits must be observed.
Check the 24 V operating voltage of the outputs
while your system is operating. Please see that
the operating voltage of the outputs lies within
the permitted tolerances even during full opera-
tion.
Recommendation
•
Use a closed loop power unit.
•
Calculate the complete current consumption
according to the following table and select
both a suitable power unit and cable cross
section.
•
Avoid long distances between the power unit
and the terminal. Calculate the permitted
distance according to Appendix A.
The following rule applies for type 03:
