Time Delay Operation

The following graphs show the operation of the time delay function.

If 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:

The LED is not affected by Time Delay when

“Automatic or

Manual”

reset mode is selected. Rather the LED follows the set

and reset points.
