Corrective Action
LCD remains blank.
• Check sensor and controller wiring and correct, if necessary.
• If wiring is okay, check to see if power is being applied to the
sensor by pushing the Override Key for less than four seconds.
If the Override LED lights up, the sensor is powered. If the
Override LED does not light up, the sensor may not be
receiving power. Check controller power to verify presence.
• If the above measures do not address the problem, download
a new application to the controller.
Sensor displays “Abn”
indefinitely.
• Check the documentation to make sure the sensor model is
compatible with the controller application and then choose one
of the following options.
• If the sensor and application are compatible, download a new
application to the controller.
• If the sensor and application are incompatible, download an
application that is compatible with the sensor. Or, install a
sensor that is compatible with the controller application.
All LCD icons light up and
remain lit.
• Check to see if the controller is constantly resetting and
correct, if necessary.
• Check sensor and controller wiring and correct, if necessary.
• If reset and wiring are okay, download a new application to the
controller.
• If the above measures do not address the problem, the
controller may need to be configured. For configuration
instructions, consult documentation associated with the
network management tool.
