2.2 Current output I
• The current output is electrically isolated from all other circuits.
• Setting data and functions can note down in the Table in Sect. 3.
Please also refer to Section 2.7 ”Standard factory settings”.
• All operating data and functions are adjustable (see Sections 4.4 and 5.6, Fct. 1.05).
• Max. load :
active operation 15-500 Ω
passive operation ≤ 800 Ω
• Selfcheck : - interrupting the mA loop, and
- short-circuit of mA loop via test function, see Fct. 2.03
or when power supply is switched on in Fct. 3.07
Error message on display (see Fct. 1.04, Section 5.4) and/or
status output (see Fct. 1.07-1.10, Section 5.8).
• Current value for error identification is adjustable, see Fct. 1.05 and Section 5.6.
• Range change-over, automatically or externally by control input,
see Sections 4.4 and 5.19, Fct. 1.07-1.10 and 1.11-12.
Setting range from 5-80% of Q
100%
(corresponding low to high range ratio from 1:20 to 1:1.25).
Change-over from high to low range at approx. 85% of low range and vice versa at approx.
98% of low range.
The active range is signalled via one of the four status outputs.
• Forward/reverse flow measurement (F/R mode) is possible (see Section 5.15).
• Connection diagrams see Section 2.6.
