4 Configuring the analog output
4.1 Automatic signal detection
The
NGR
can automatically detect which signal is required using the connected output
load (see Chapter 9 "Technical data").
The following information 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
Configuration
■
Access the
QAMENU-TYP
menu using the arrow and Set pushbuttons.
■
Set the QAMENU-TYP menu to Auto?
■
Note: Automatic signal detection is only active when the device is switched on for the first time.
After this the function can be activated in the QAMENU-TYP menu with Auto? again.
4.2 Current output 4-20 mA
Configuration
■
Set upper limit value (20 mA)
○
Set the value in the QAMENU-QAHIGH menu to level in mm (e.g., 500 mm)
■
Set lower limit value (4 mA)
○
Set the value in the QAMENU-QALOW menu to level in mm (e.g., 10 mm)
■
Invert 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
■
Select electrical signal
○
Set the parameter in the QxMENU-QATYP menu to 4–20 mA
4.3 Voltage output 0-10 V
Configuration
■
Set upper limit value (10 V)
○
Set the value in the
QAMENU-QAHIGH
menu to level in mm (e.g., 500 mm)
■
Set lower limit value (0 V)
○
Set the value in the QAMENU-QALOW menu to level in mm (e.g., 10 mm)
■
Invert 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 0 V and QALOW 10 V
■
Select electrical signal
○
Set the parameter in the QxMENU-QATYP menu to 0–10 V
