Setting changes - Settings
Any change on the following parameters are stored:
• Output relays (function, logic and mode).
• CB position monitoring enabling.
• TCS enabling.
• Threshold changes.
Ten events are recorded into a circular FIFO (First In, First Out) buffer.

Self-test
Following information are available (Read \ Self test \ Info menu):
• Type
• Self-test cause
• Self-test latch
The relay self-test function classifies relay operational anomalies according to three levels:
- MINOR ANOMALY: The device continues to function within the possible limits with the protective
devices activated;
- MAJOR ANOMALY: Operation of the device may be corrected by the operator by resetting the
initial (default) configuration and hence the desired settings;
- FATAL ANOMALY: All logic and protective functions are inoperative and the relay must be returned
to the factory.
The internal self-test function is capable of detecting the following anomalies and indicating them
by means of messages:
- defective auxiliary power supply (FATAL ANOMALY);
- output relay coil breakage (FATAL ANOMALY);
- alteration of the calibration data stored in EEPROM memory (FATAL ANOMALY);
- alteration of the parameters (threshold setting, times, relays… etc.) in EEPROM memory (MAJOR
ANOMALY);
Note 1 The last change on settings ia stored inside memory addressed by the Last setting (1...10) parameter
Note 2 Counter is updated at any new record; it may be cleared by means ThyVisor
