1.1 OUTPUT B1
1.1 OUTPUT B1
1.1 OUTPUT B1
1.1 OUTPUT B1
Output B1 is a binary switching output. In Fct. 3.2, one of the following functions can be
selected for this output:
INACTIVE, SWITCH POINT, COUNT. LIMIT, PULSE OUTP.
One of the following functions can be selected as contact type in Fct. 3.3:
NORM.OPEN
1
/ NORM.CLOSED
2
1.1.1
INACTIVE
-
MEAS.VAL. B1
Switching point of flow value
Value range: 0.0
…
full scale range
The switching point is entered in flow units.
If the current flow value exceeds this pre-determined switching point, output B1 changes
its binary state
3
.
In Fct. 1.1.2 a hysteresis can be specified additionally.
CNT. VAL. B1
Switching point of totaliser value
Value range: 0.0
…
counter limit
The switching point is entered in volume or mass units.
If the the current counter value exceeds this pre-determined switching point, output B1
changes its binary state
3
.
There is no hysteresis setting for the switching point of the counter value.
PULSE WIDTH
Pulse weight (pulse/unit)
The weight is only displayed here.
A configuration takes place in Fct. 1.3.1 PULSE WIDTH, 1.3.2 PULSE/UNIT and 3.11.2
COUNTER.
1.1.2 HYST. B1
Hysteresis for the switching point of the flow value
Value range: 0.0
…
switching point
If the current flow value exceeds the pre-determined switching point from Fct. 1.1.1,
output B1 changes its binary state
3
.
In order for output B1 to change its binary state back to the initial setting, the switching
point made smaller by the hysteresis must be undershot

Example:
Example:
In 1.1.1, a switching point of 200 L/h is set.
The possible value range for the hysteresis is then 0.0
…
200 L/h.
With a hysteresis value of 0, the switching point has no hysteresis (
3
=
4
).
If a hysteresis value of 20 L/h is entered, output B1 changes its binary state to the initial
setting, if it drops below 180 L/h
