Time Delay Operation

The following graphs show the operation of the time delay function.
When the signal crosses the set point, the On time delay timer starts and the
relay trips when the time delay has elapsed. If the signal drops below the set
point (high alarm) before the time delay has elapsed, the On time delay timer
resets and the relay does not change state. The same principle applies to the Off
time delay.
Note: If "Automatic or Manual (A-mAn)" reset mode is selected, the LED follows
the reset point and not the relay state when the relay is acknowledged.
