7. Functional principle of the switching points
Alarms / optical switching point display
An activated switching point can be optically indicated by flashing of the 7-segment display.
Functional principle of the alarms
Alarm Deactivated, display value
Threshold Threshold value / limit value for switch over
Hysteresis Width of the window between the thresholds
Operating principle Limit value exceedance / limit value undercut
7. Functional principle of the switching points
Limit value exceedance “ ”
The switching point S1-S2 is “off” below the threshold and “on” on reaching the threshold.
Limit value undercut “ ”
The switching point S1-S2 is “on” below the threshold and switched “off” on reaching the
threshold.
