Potentialfree binary input as "Flow Switch"
logical value input voltage
Input signal:
Not inverted (Inv = No) Input signal:
Inverted (Inv = Yes)
Open contact (*) 0 / Ok 1 / No Flow
0 … 4.5 V (*)
13 … 35 V (*) 1 / No Flow 0 / Ok
(*) The input voltage has to be applied continuously in the according range longer than the parameterized
delay time, before the logical value is accepted or changes.
Frequency- or 4-20mA-input as “Flow Switch”
input value logical value
< SP No Flow (**) 1 / No Flow
>= SP No Flow (**) 0 / OK
(**) The input value has to be available according to the requirement (< or >=) longer than the parameterized
delay time, before the logical value is accepted or changes.
