You can set the relay to activate when the probe measurement exceeds or falls below a set
limit. When you configure a single setpoint for relay activation without hysteresis, the
relay switches on or off immediately when the measurement moves over or below the setpoint.
Figure 1. Relay settings example: one setpoint without hysteresis
To define a single setpoint for relay
activation when the measurement exceeds the defined activation limit (Activate above) without using hysteresis:
Select
to access Insight main menu.
In the Configure Device menu, select either relay A or relay B.
Enable the relay output by setting Relay output on/off to ON.
Select the measurement parameter that is used to control the relay with the Output parameter dropdown.
The parameter options depend on the connected probe. Note that the parameter units are
defined in the Settings menu: see Unit settings.
Enter the activation limit value in the Activate above field.
With this configuration,
there is no hysteresis buffer. The relay activates or switches off immediately after
passing this point.
Leave the Activate below field empty and set the Hysteresis field value as 0 (no hysteresis).
