OPERATION

The window function enables monitor-
ing of a defined range. If the level is
between window high (FH) and window
low (FL), the output will be active
(normally open) or inactive (normally
closed).
The error status of the measuring
device reflects the cable break monitor
-
ing. During an error status, the measur
-
ing device switches to a safe state; i.e.
the switching outputs become inactive.
As far as the downstream signal evalu-
ation is concerned, this corresponds to
a cable break.

Normally open with configurable hysteresis
Applications
−
Dry run protection
−
Empty signal
Configuration
Configure the Qx switching output as normally open (using Q1 as an example).
Note:
The switching output designation (Q1 in the example here) changes according to the
selected process variable to be output.
The following configuration is only possible if the value is set to
LEVEL or TEMPER under
PROC1.
1.
Log in to Exprt mode, see
2.
Configure the switching output as output in the
Q1-### / MODE1 / OUTPUT menu.
3.
Configure the process variable to be output.
•
Set the value to LEVEL or TEMPER in the Q1-### / PROC1 menu.
4. Set the Hysteresis mode in the Q1-### / OUT1 / HYST. menu.
•
Set the parameter to NO in the Q1-### / POL1 menu.
5. Set the switching point.
•
Set the value in the Q1-### / SP1
menu to level in mm (e.g., 500 mm).
6. Set the reset point.
•
Set the value in the Q1-### / RP1
menu to level in mm (e.g., 450 mm).
7. Select the electrical property (NPN/PNP/DRV [push/pull]).
Select the parameter in the Q1-### / TYP1 menu.
The following rules apply:
