Circuit diagram with analog value comparator.
Figure 50: Signal diagram of analog value comparator in Less
than/equal to mode
1: actual value at I7
2: setpoint plus hysteresis value
3: setpoint
4: setpoint minus hysteresis
The make contact switches off when the actual value at I7
exceeds the setpoint plus hysteresis. If the actual value at I7
equals or falls below the setpoint, the make contact switches
on.
