Connection of the NW16 level monitor
DANGER
Risk of explosion if the level monitor is installed in potentially explosive areas!
The NW16 level monitor does not have its own explosive protection class.
- The NW16 level monitor may only be installed outside potentially explosive atmospheres!
CAUTION
Do not apply external voltage!
An external voltage which is applied destroys the component.
The level detection for two pumps can be performed using the NW16 level monitor. The level monitor has the following switching points:
- Pump 1 On/Off
- Pump 2 On/Off
- High water alarm
The level control corresponds to operation with separate float switches. The internal structure of the level monitor ensures hysteresis between the activation/deactivation level of the relevant pump.
Insert the connection cables laid by the customer through the threaded cable glands and secure. Connect the wires to the terminal strip according to the connection diagram.
