3.4 Logic Inputs
Safety notes:
– Do not run logic input wiring together with power cables.
– Use an external dry contact capable to switch 0.5 mA,
5 VDC.
– The instrument needs 150 ms to recognize a contact sta-
tus variation.
– The logic inputs are NOT isolated by the measuring input.
A double or reinforced isolation between logic inputs and
power line must be assured by the external element.
