ION Setpoint module- How will the module behave if both the high and low limit are set to the same value for either greater than or less than comparison? Will this cause any issues?

Resolution:

When you set both the high and low limits to the same value, the meter effectively has zero deadband. This can lead to constant triggering and rapid toggling of the setpoint outputs, depending on how the measured value hangs around that threshold.

1. The Pickup and Dropout settings define triggers based on threshold crossings (Over and under conditions).
2. I would suggest always adding a small buffer between the high and low limits (e.g., High = 20, Low = 15).

While setting both limits to the same threshold is technically allowed, it is generally poor design/configuration and this removes essential deadband, which can compromise the accuracy of your outputs.
