13 Sensor Failure
Mode of
Operation
Select from the drop-down menu how you want the relay output to respond when the
reference sensor or reference sensor wiring fails.
• If you choose Fail Off, the analog output generates the selected OSP (Output Signal
Strength at Setpoint) value to the controlled device.
• If you choose Fail On, the analog output generates the selected OEP (Output Signal
Strength at End Point) value to the controlled device.
In this example, Fail Off is selected. Therefore, if the reference sensor (Sn-1) or sensor
wiring fail, OUTA-2 provides the selected OSP (10%) to the controlled device until the
sensor failure is resolved.
14 (Output) Name Assign a 16-character or less web UI name for the analog output.
Note: You are not required to assign an output name. When you assign an output name,
the assigned name is displayed on the Overview page, the System Configuration
page, the Output Configuration pages and the Sensor Configuration page.
In this example, the assigned name is Cond Fan 2.
