DIAGNOSTICS
| | The relay assigned to this On/Off control output during I/O
setup will already be filled in. (This is read-only
information.)
Specify the process value or computed value to be used
as the input.
Specify whether relay activation should occur when the
input’s value exceeds the setpoint (HIGH action) or falls
below the setpoint (LOW action).
Enter the setpoint.
If desired, specify a deadband. (Once the output is ON, it
will remain ON until the controlled variable differs from the
setpoint by at least the value of the deadband.)
Enter the percent of the cycle period that the relay should
stay on when the setpoint is reached.
