A value range of the output variable is
assigned to a physical output signal.
The ex-factory setting corresponds to an
output value of 0 ... 100 % for controller
outputs.
No changes of the ex-factory setting are
required for continuous controllers.
For a 3-state controller, enter the following
settings for cooling: Zero point = 0 / End
value = -100
Example (function as a transducer):
The analog output (0...20 mA) is to be used
to put out the process value (value range:
150...500 °C), this means:
150…500°C = 0…20 mA
Zero point: 150 / End value: 500
End value
End

7.7 Binary functions
In terms of this manual a function initiated by a binary signal is
called “binary function”. Several binary functions can be realized
by using the signals of binary input, limit comparators, timer and
ramp function.
Switching behavior
The following binary functions react to switch-on edges:
• Start, abort self-optimization
• Start, abort, start/abort timer
All remaining binary functions react to switch-on or switch-off
states.
