Application Examples
Detection of Dust Exhaust
The change in the density of the dust is detected via the E3SA and
discriminated by the K3GN.
Monitoring of Tank Pressure
The output of the pressure sensor is processed and the pressure is
displayed. Remote monitoring of the operation is possible with the
communications function.
Monitoring of Motor Load Current
If the startup time compensation of the K3GN is enabled, the K3GN
will not be influenced by the inrush current from starting the motor,
and no signal will be output from the K3GN.
Monitoring Difference between Two
Line Speeds
The difference between the two line speeds is calculated by the PLC
and the result is written via RS-485 to the K3GN where it is
displayed.
Monitoring the Remaining Quantity of
Soup
The distance to the surface of the soup is detected with an ultrasonic
sensor and, based on this distance, the K3GN displays the remaining
quantity. When the remaining quantity of soup decreases to less than
20%, the K3GN lights the “Replenish” indicator.
