Configuration of output 1
5 settings can be selected:
- Output signals for flow rate:
•
Hno
= hysteresis function / normally open
•
Hnc
= hysteresis function / normally closed
•
Fno
= window function / normally open
•
Fnc
= window function / normally closed
- Output signal for the meter:
•
ImP
= Pulse sequence or On / Off signal for preset counter
(
→
parameter
ImPS
and
ImPR
)
Pulse repetition
Determines which signals are provided by the meter at output 1,
2 settings can be selected:
•
YES
: Pulse repetition active (= simple counter function):
Output 1 provides a counting pulse every time the value set in
ImPS
is reached.
•
no
: Pulse repetition not active (the counter operates as a pre-
set counter): Output 1 switches (OUT1 = ON) when the value
set in
ImPS
is reached. It remains switched until the counter is
reset (

page 37, parameter
rTo
).
ImPR
is only active if OU1 =
ImP.
Configuration of output 2
4 switching functions and 1 analogue signal can be set for flow
rate
•
Hno
= hysteresis function / normally open
•
Hnc
= hysteresis function / normally closed
•
Fno
= window function / normally open
•
Fnc
= window function / normally closed
•
I
= analogue signal (4 ... 20 mA)
Analogue start point
Measured value at which 4 mA is provided.
ASP is only active if OU2 =
I
.
Analogue end point
Measured value at which 20 mA is provided.
Minimum distance between ASP and AEP = 25% of the final
value of the measuring range. AEP is only active if
OU2
=
I
.
