Monitoring limiting
values using one or two
relays
Fig. 6-1
Switching points for relays with the function of a limit indicator
A switching delay (t) can be set up for each relay for switching
processes. This is the time period for which a limiting value must be
exceeded before the relay switches. This prevents frequent switching if
the measured values are close to the limiting value.
1
Upper limit value (relay 1) exceeded
2
Selected switching delay t1 for relay 1 expired
Relay 1 switches
3
Hysteresis for upper limiting value (relay 1) undercut
4
Selected switching delay t1 for relay 1 expired
Relay 1 switches back
5
Lower limit value (relay 2) undercut
Selected switching delay t2 for relay 2 expired
Relay 2 switches
6
Hysteresis for lower limiting value (relay 2) exceeded
Selected switching delay t2 for relay 2 expired
Relay 2 switches back
