From the System Status screen navigation bar, select Tool Box, then Help. This help screen will show the date of the last
configuration change, configuration version, previous user, about TPPR and the service contact options.
The configuration version increments every time that parameters are written to the TPPR, including during calibration. The
configuration version can also be used as a check against unauthorised modification of the system.

13.16 System State Relays
The Control Module has two System State relays, rated at 30 VDC, 3 A or 250 VAC, 3 A. The contacts are closed in normal
operation and open under the following conditions:
The System Fault relay is open if one or more of the conditions listed in Table 40. are present.
The System Failure relay is open if one or more of the conditions listed in Table 40. are present.
The System State relays and any other relays configured for safety purposes should be wired to a continuously monitored
system for safe operation. This is to ensure that all system faults are detected promptly and appropriate action taken.
Note: During start-up, the System Failure relay is open until the CCB is available.
Note: The Redundant CCB taking over from a failed Master CCB is not considered to be a system failure, and the System
Failure relay will remain in normal state.
