COMMISSIONING
NOTE
Pulse output can only be selected if Volume (flow and counter) measurement mode has
been selected.
The Flow Current 4-20mA and Temp Current 4-20mA selections are only shown in the
electrical version B with an analog output.
7.3.4
Configuring the switching output Q1 and Q2
When the flow (or temperature) varies by the configured value, the hysteresis keeps the
switching state of the outputs stable.
When the flow (or temperature) increases, the output switches when the respective
switchpoint (SP1) is reached. When the flow (or temperature) drops again, the output
does not switch back until the reset switchpoint (SP2) is reached.
The window function allows you to control a specified range. When the flow (or tempera
-
ture) is between window high (SP1) and window low (SP2), the output is active (normally
open) and/or inactive (normally closed).
The cable break monitoring indicates the error status of the measuring device. When
in error status, the measuring device switches to the safe state. The safe state of the
electronics is in the pull-down configuration.
As far as the downstream signal evaluation is concerned, this corresponds to a cable
break.
7.3.5
Normally open with configurable hysteresis
Configuration based on Q1 for flow (as an example)
1. Use the arrow keys (left/right) to select
Q1 Mode
.
2. Use the arrow keys (up/down) to select
Flow Hysteresis norm open
.
3. Use the right arrow key to select
Q1 Switchpoint 1
(SP1).
4. Increase or decrease the value using the arrow keys (up/down).
5. Use the right arrow key to select
Q1 Switchpoint 2
(SP2).
6. Increase or decrease the value using the arrow keys (up/down).
7. The sensor uses the larger switchpoint as the upper switching threshold, and the
smaller switchpoint as the lower switching threshold.
8.
If required, configure the delay mode and time (see
).
