8 OPERATION
8.3 Conguring the analog output
8.3.1 Automatic signal detection
The LFP can automatically detect which signal is required using the connected output
load.
Where the following applies:
• 4 mA to 20 mA < 500 ohms at Uv > 15 V
• 4 mA to 20 mA < 350 ohms at Uv > 12 V
• 0 V to 10 V > 750 ohms at Uv ≥ 14 V
Conguration
1. Access the QAMENU-TYP menu using the arrow and Set pushbuttons.
2. Set the QAMENU-TYP menu to Auto?
Note:
Automatic signal detection is only active when the device is switched on for the rst
time. After this the function can be activated in the QAMENU-TYP menu with Auto?
again.
8.3.2 Current output 4 mA ... 20 mA
Conguration
1. Set upper limit value (20 mA).
• Set the value in the QAMENU-QAHIGH menu to level in mm (e.g., 500 mm).
2. Set lower limit value (4 mA).
• Set the value in the QAMENU-QALOW menu to 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 congured
• QA-INV = Analog output signal is inverted; QAHIGH 4 mA and
QALOW 20 mA
4. Select 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
Conguration
1. Set upper limit value (10 V).
• Set the value in the QAMENU-QAHIGH menu to level in mm (e.g., 500 mm).
