Min/Max Connection of both sensor inputs
The bowl feeder switches of, when both sensor inputs are assigned. When both sensors are free, the
bowl feeder (channel 1) switches on. Relay K1 switches with switching off of the bowl feeder. Relay K2
switches 4 sec later (Blow-off switching)
Level control for the hopper with external control
Sensor 2 switches relay K1 according to the entered delay time (C005). When the sensor 1 is darkened,
relay K1 releases (looking of the hopper).
Application: Sensor 1 = back pressure control
Sensor 2 = level control
Relay K1 = hopper control
Level control for signal lamp
Sensor 2 switches relay K1 according to the entered delay time (C005), without consideration of sensor
1 (Back pressure control).
Application: Sensor 2 will be used as a level control (e.g. LC-N 24V DC). Relais K1 switches with a
signal lamp:

The cycle monitoring system monitors the FREE sensor state. The time (A 180) is used to set the
maximum time which a sensor may be free before an alarm signal is issued.
Relay K2 is picked up when an alarm signal is issued. The fault is cleared by covering the sensor.
I
f OUT = 1 and a fault occurs, the bowl feeder will also be switched off in addition to relay K2 (indicator
lamp: fault) and an ERROR message will appear in the display. The fault is cleared with the cursor key
at the bottom right.
If OUT = 0 and a fault occurs, only relay K2 is energized (indicator lamp: fault). The fault is cleared
automatically when sensor 1 is assigned.
If A.I. = 1 Relay K1 is checked on breakdown (switch changed over from relay K2 to K1)
