OPERATION
8.3
Configure the analog output
8.3.1
Automated signal detection
The LFP can automatically detect which signal is required based on the connected
output load.
The following rules apply:
•
4 mA ... 20 mA < 500 ohms at Uv > 15 V
•
4 mA ... 20 mA < 350 ohms at Uv > 12 V
•
0 V ... +10 V > 750 ohms at Uv ≥ 14 V
Configuration
1. Access the QAMENU-TYP menu using the arrow and Set pushbuttons.
2.
Set the QAMENU-TYP menu to Auto?.
Note:
Automated signal detection is only active when the device is switched on for the first time.
After this the function can be activated again in the QAMENU-TYP menu with Auto?.
8.3.2
Current output 4 mA ... 20 mA
Configuration
1. Set the upper limit value (20 mA).
•
Set the value in the QAMENU-QAHIGH menu to the level in mm
(e.g. 500 mm).
2. Set the lower limit value (4 mA).
•
Set the value in the QAMENU-QALOW menu to the level in mm
(e.g. 10 mm).
3. Invert the signal.
The analog signal can be inverted in the QAPOL menu.
Set the parameter in the QxMENU-QAPOL menu to QA-INV.
•
QA-NRM = Analog output signal as configured
•
QA-INV = Analog output signal is inverted; QAHIGH 4 mA and
QALOW 20 mA
4. Select the electrical signal.
5.
Set the parameter in the QxMENU-QATYP menu to 4 mA ... 20 mA.
8.3.3
Voltage output 0 V ... +10 V
Configuration
1. Set the upper limit value (10 V).
•
Set the value in the QAMENU-QAHIGH menu to the level in mm
(e.g. 500 mm).
