A1.Fu, A2.Fu: Limit value behavior
With the operating principle it is possible to switch between different working types of the
switching outputs. Is Ax.Fu = oFF selected, the associated setpoint parameters are not
displayed.
The switching point is without function and associated parameters are not displayed
oFF
(Default state).
The switching point is switched on in measuring mode and associated parameters
On
except for Ax.Er and Ax.tY are`t displayed.
HI-LI Switch when limit value is exceeded.
Lo.LI Switch when limit value is undershot.
rAnG Switching in the specified range.
Out.r Switching outside the specified range.
A1.Er, A2.Er: Message in case of limit value error
If a device checksum is not correct or the display range is violated, you can specify the behavior
of the switching points.
The selected switching point behavior is activated. In push-pull operation HIGH/L+ is
on
switched.
The switching points behave in the opposite way. The error behavior overwrites the
oFF
actual limit value function when an error occurs.
An error has no defined effects. This means a value of 10,000 for the overflow
no
evaluation and a value of -2,000 for the underflow evaluation.
A1.tY, A2.tY: Switching behavior of the outputs
Depending on the wiring, the switching outputs support different operating modes and work in an
inverting manner. This means that the switching outputs are deactivated in the event of an alarm
condition. Thus, in case of device failure, the alarm condition is maintained.
nPn Here, without alarm conditions, the output is actively switched to GND.
PnP without alarm condition the output is actively switched to the power supply
PnP
(rectified, filtered internal device supply).
Ac.HI Here the output is switched to HIGH or power supply without alarm condition.
Ac.LO Here without alarm condition the output is switched to LOW or GND.
A1.L1, A2.L1: Switching threshold
Here the switching threshold is specified, from which an alarm reacts or is activated/deactivated.
With the window function of a switching point, this parameter is not queried.
A1.HY, A2.HY: Hysteresis
The hysteresis defines a difference to the limit value by which an alarm reacts delayed. This
parameter is not queried during the window function of a switching point.
