Temperatures are defined in the manufacturing software and then fed automatically into the PLC machines/ovens based on the production plan. The line starts only after achieving the minimum temperature as specified by the software. Temperature loss can be caused by a variety of factors, and hence a fail-safe in ensured. If for any reason the temperature goes off the specified range, the line triggers an audible alarm and simultaneously tags the production unit for special inspection. The alarm is audible for 5 minutes and if the temperature is not controlled within this time, the line is automatically stopped. The meters tagged while the alarm is triggered are inspected separately and tested rigorously before being transferred as a defect free material to the warehouse. If it fails, its recycled or sold as off spec.
