6.8.2.2 "Output Driver" parameter
Push-pull or NPN o.c.
NOTE
If the Reset Input function has been selected for pin 5, this parameter is not visible for
pin 5.
Setting values:
Push-pull: In terms of circuitry, a push-pull output consists of a
Combination of an NPN and a PNP transistor. Through this
it is possible to configure the output either as an NPN or a
PNP output, i.e. a load can be connected both between
the output and 0 V as well as between the output and supply
Voltage can be switched.
The output shows either Low-Potential (< approx. 1 V) or High-
Potential (> supply voltage - approx. 1 V)
NPN o.c.: An output of the NPN o.c. type. (open collector) consists of a
Transistor whose open collector is connected to the output pin.
It either shows low potential at the output or leaves it open.
An NPN o.c. output therefore requires the wiring with a
load (e.g. a resistor) between output and supply
Voltage or an external voltage. The parallel connection
of several NPN o.c. outputs are permissible, in order to achieve a
OR function: As soon as at least one of the
parallel connected NPN o.c. outputs show low signal,
the Output Signal Low
NOTE
The following parameters are only visible if the function "Flow switch" or "Temp
switch" has been selected!
6.8.2.3 "Switch mode" parameter
Limit switch type
Setting values:
Single point max -
The measured value is compared with a limit value.
If the limit value is exceeded, an alarm event is triggered.
Single point min -
The measured value is compared with a limit value.
If the limit value is undercut, an alarm event is triggered.
Window -
The measured value is compared with two limit values. If the limit
value is either exceeding or undercut an alarm event is triggered.
