|Note that the values given must match the parameter and unit selections.|
- The relay activates when the measurement rises above or falls below a single setpoint, and deactivates when the measurement returns to the other side of the setpoint value.
- When you set a higher value for Activate above and a lower value for Activate below, the relay is passive when the measured value is in between the setpoints.
- When you set a lower value for Activate above than for Activate below, the relay is active when the measured value is in between the setpoints.
For examples of different relay activation options, see Relay activation and hysteresis examples.
Note that the hysteresis configuration has an effect on relay activation and deactivation. For more information on hysteresis, see Relay hysteresis. The effect of hysteresis is also described in the examples in Relay activation and hysteresis examples.
