4.- OPERATION
The equipment is designed for 50 Hz and 60 Hz installations.
This equipment may be used as for earth leakage measurement or for earth
leakage protection. This will depend on the connection (earth leakage protection) or
not (earth leakage current measurement) of the operational relay outputs for the
different channels.
The CBS-8 has several operating modes:
- Normal mode: The CBS-8 continuously measures currents. If the relay
outputs are connected it will be used for earth leakage protection or as a
current relay.
- Test mode: Checks the status of the connections between the CBS-8 and
toroidal as well as the working of the different LEDs.
- Reset mode: Allows the tripped channels to be reset.
- Set up mode: Allows the relay station to be configured.
The CBS-8 will always be in normal mode when it is switched
on.
It has 4 buttons and 5 LEDs that have a different following function according
to mode.
The CBS-8 has a non volatile, rotating memory where the 100 most recent
events are logged. Each log shows:
- Date
- Channel tripped
- Trip current
