Signal diagram of analog value comparator in Less than mode
1: actual value at I7
2: setpoint plus hysteresis value
3: setpoint
4: setpoint minus hysteresis
The N/O contact switches off when the actual value at I7 exceeds the setpoint
value plus hysteresis. If the actual value at I7 falls below the setpoint value, the
N/O contact switches on.
