6.18. Module Temperature Measurement

Temperature measurements are made on the module for general monitoring purposes. These are

indicative only and are not intended to provide accurate temperature readings.

6.19. Diagnostics

Wherever possible the Trusted

standard diagnostics have been maintained. Because of the nature

of the design these have been modified so as not to escalate any failures to a position which would

result in a rod motor being de energised. The module has however been supplied with an application

interface which can cause the outputs to shutdown and de-energise if required.

Items such as loss of communication between the module and the Main Processor will result in a

degradation process which maintains the outputs in the last controlled state where ever possible (3-2-

Maintain last state).
