IMAGO F3000 / 10.01 77
7 Setup Program
7.7.4 Names
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.
7.7.5 Analog outputs
Here you can define the signals that are given out on the (max.) four analog
outputs, and the response to overrange/underrange.
Analog output 1— 4
Selection/settings Description
Function (Analog selector) The value which is to be presented at the analog
output.
Analog input 1
Analog input 2
Analog input 3
Analog input 4
Output signal
0 — 10V The electrical signal on the output.
2—10V
0—20mA
4—20mA
Zero point -1999 to 0 to +9999 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
End value -1999 to 100 to +9999
Offset -1999 to 0 to +9999 A constant shift that is applied to all the analog
output values.
Overrange/
underrange
Accept the present value The last value is given out continuously.
0 — 100: fixed value is given out
Value entry
k / bold = factory setting
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
