OPERATION
Configuration
Configure the Qx switching output as input (using Q1 as a redundant overfill protection
example).
Note:
The switching output designation (Q1 in the example here) changes according to the
selected process variable to be output: Q1-LVL or Q1-TEMP is now Q1-INP.
1.
Log in to Exprt mode, see
2.
Configure Q1 as input.
•
Set the parameter to INPUT in the Q1-### / MODE1 menu.
3.
Configure the action to be performed when the signal is present.
•
Set the parameter to MAXLVL in the Q1-INP / ACTIO1 menu (if the external
signal is present, the CFP Cubic outputs the
MAXLVL status).
4.
Configure the form of the external signal.
•
Set the parameter to NO (normally open) in the Q1-INP / POL1 menu.

Configuration of analog outputs
8.4.1
Automatic signal detection
The CFP Cubic can automatically detect if a 4–20 mA or 0–10 V signal is required
using the connected output load.
The following rules apply:
•
4 mA to 20 mA if load < 500 ohms at U
V
> 15 V
•
4 mA to 20 mA if load < 350 ohms at U
V
> 12 V
•
0 V to 10 V if load > 750 ohms at U
V
≥ 14 V
Configuration
Note:
The analog output designation (QA in the example here) changes according to the
selected process variable to be output.
1. Perform automatic signal detection.
•
Set the parameter to AUTO in the QA-### menu.
Note:
Automatic signal detection is only active when the device is switched on for the first
time. After this, the function can be activated again with
AUTO in the QA-### menu.
