Please note
Common operating and load voltage supplies for pin 1
(electronics and inputs) and pin 2 (outputs/valves):
S In this case, note that the lower tolerance of ±10 % for
both current circuits must be observed.
Check the 24 V load voltage of the outputs while your system
is operating. Make sure that the load voltage of the outputs
lies within the permitted tolerance even during operation at
full load.
Recommendation:
Use a closed−loop power unit.
