Level check for hopper control by external controller
Sensor 2 operates relay K1 following the delay period entered (C005). When sensor 1 is operated, re-
lay K1 drops out. (Hopper interlock)
Application: Sensor 1 = accumulation check
Sensor 2 = level check
Relay K1 = hopper control
Level check with indicator light
Sensor 2 operates relay K1 following the delay period entered (C005) without taking into account sensor
1 (accumulation check).
Application: Sensor 2 is used as a level checker (e.g., LC-N 24V DC). Relay K1 operates an indicator
light: Bowl feeder empty.
5.5.7. Code C008 cycle monitoring
Objective:
Monitoring of sensors 1 (accumulation check) and/or 2.
When activating the cycle monitoring function, the "AND, SOL" links in code C006 must not be activated!!!

The cycle watchdog monitors the CLEAR sensor status. The time (A 180) sets the maximum duration
for which a sensor is allowed to be clear before an alarm message is generated.
In case of an alarm the relay K2 is clocked on and off. Reset takes place automatically when the sensor
is operated again.
If OUT = 1 the alarm operates relay K2 (indicator light: Error) and also stops the bowl feeder. An ER-
ROR message appears on the panel display. Use the bottom right cursor button for reset.
If OUT = 0 the alarm only operates relay K2 (indicator light: Error). Reset takes place automatically
when sensor 1 is operated.
If A.I. = 1 relay K1 is clocked on and off in response to the alarm (switching from relay K2 to relay K1).
