Designations can be defined here for
- Control contacts
- Relay outputs
- Logic inputs
- Analog inputs
- Analog outputs
to correspond to their functions. These names appear in the various selection
lists in the setup program, and make configuration easier.
The names can be up to 16 characters long.
Here you can define the signals that are given out on the (max.) four analog
outputs, and the response to overrange/underrange.

Description
The value which is to be presented at the analog
output.
The electrical signal on the output.
The range of values for an output variable is
assigned to an electrical output signal.
Example:
An analog output (0 — 20mA) is to be used to give
out setpoint 1 (range of values: 150 — 500°C)
i.e. 150 — 500°C corresponds to 0 — 20mA,
Zero point: 150 / End value: 500
H
Setting a controller output for cooling.
With proportional controllers using direct
action for cooling (or double-setpoint
controllers), the settings must be made as
follows:
Zero point: 0 / End value: -100
A constant shift that is applied to all the analog
output values.
The last value is given out continuously.
0 — 100: fixed value is given out
