Relay Sampling Operation
When the signal crosses the set point, the relay trips and the sample time starts. After the sample time
has elapsed, the relay resets. The cycle repeats every time the set point is crossed, going up for high
alarms and going down for low alarms.
The sample time can be programmed between 0.1 and 5999.9 seconds.
