Electrical Connection of the Monitoring Devices
NOTE
In order to prevent potential nuisance alarms, Busch recommends that the control system is
configured with a time delay of at least 20 seconds.
6.5.1
Wiring Diagram Level Switch (Optional)
Part no.:
0652 567 576
Connector:
M12x1, 4-pin
Electrical data:
U = 10 – 30 V DC
I consumption : <15 mA
I output max : 150 mA
Switch point:
Pin 1 = low level
1 = Brown: 24V DC
3 = Blue: Supply 0V DC
4 = Black: Signal low level
NOTE:
For this device, the recommended time delay to
prevent nuisance alarms can be up to 240
seconds.
