Protocol. The behavior is identical to the HMI. The relay will synchronize the date and
time, and a new synchronization event is carried out.
6.5.
Self-diagnosis
Diagnostic algorithms are run while the equipment is being started up and continuously when the
relay is operating. This diagnostic is a preventative process to guarantee that the equipment is in
good operational condition.
As general considerations, the following issues are pointed:
•
Communications between different CPUs are confirmed by the corresponding integrity
checking. If continuous anomalies are detected, the equipment will be reset.
•
Data related to set values are confirmed by the corresponding checking. Likewise, all
setting tables are doubled, and the relay has the capability for working with a damage
table, but not with two damaged tables.
•
There is a Watchdog device both between and in main CPUs. If any CPU goes out of
operation the equipment will be reset and this condition will be identified as an event.
The following state bits are associated with this process:
Measurement error
Problem in the measurement block
No Trip Power
There is not the required energy to trip
Eeprom error
Problem in the Eeprom memory, some group is corrupted. Remaining that
setting (both group) are duplicated in Eeprom chip.
Events error
Problem on the events recording
No Trip Power
message indicates the relay has not enough energy to trip. This situation is not
permanent, and it is solved once the relay achieves the necessary energy to trip thank to enough
time has passed, more current is injected or other auxiliary supply is used.
The other errors are related with the communication of the 2 microprocessors that are included in
the relay.
Measurement error
event always is generated when the BATTERY key is pressed because when
this key is pressed only one of the microprocessors is operative.
If this problem occurs with a model without commissioning battery and appear on the stanby
screen or any of the other 2 situations appear on the main screen (
EEPROM ERROR or EVENTS
ERROR
), the relay should be replaced and it will be necessary to contact Fanox.
On the other hand, “Default settings” means that the equipment is operating under factory settings,
being all protection functions disabled.

Digital Outputs
Optionally (to be selected for each model), the SIA-B equipment has up
to 2 configurable outputs.
By default, the configuration is as follows:
•
Output 2: activates when the relay is ready
•
Output 3: activates when a trip occurs
