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-nmAn
) reset mode is selected, the LED
follows the reset point and not the relay state when the relay is
acknowledged.
