During normal Day-to-Day operation:
•
The TPPR system will collect data every 250 ms from all of the Input/Output modules on the Ring Network
•
The Cause and Effect matrix will be evaluated every 250 ms, and commands sent accordingly to the appropriate
output channels. System response time for AIM is ≤3 s and ≤1 s for DIM
•
Any change in status of an I/O channel will be reported to the User Interface and logged in the event history
•
Any occurrence of any of the events listed in Chapter 11 will be reported on the User Interface and logged in the
event history
•
Any system fault or inhibit will activate the System Fault relay
•
Any failure of the safety function e.g. due to major fault or power loss will activate the System Failure relay

During active events the status changes and an alarm may sound.
