Pin assignment
L
WARNING
Is the supply voltage switched off?
Risk of electric shock!
‣
Switch off the supply voltage before connecting the device.
• PIN 1: L+ (supply voltage U
B
)
• PIN 2: L- (0 V)
• PIN 3: Not assigned
Supply voltage
The supply voltage (mostly 24 V DC) must be greater than the sum of the voltage drop U
s
at the sensor, the voltage drop of 5 V at the display and other voltage loss U
a
(such as
additional evaluation and power loss).
The following therefore applies: U
b
= U
s
+ 5 V + U
a
Post-connection check
Is the device or cable undamaged (visual check)?
Are all cable glands installed, securely tightened and leak-tight?
If supply voltage is present, is the device ready for operation and do values appear on the display module?
