Figure 48: 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 plus hysteresis. If the actual value at I7
falls below the setpoint, the n/o contact switches on.
