Troubleshooting
This chapter covers possible issues with the basis weight sensor. It is divided into two sections:
• Alarm based troubleshooting: Troubleshooting steps to be taken in response to a specific alarm generated in
the Experion MX system.
• Non-alarm based troubleshooting: Troubleshooting steps that may not be related to a specific alarm in the
Experion MX system
