172 Technical Handbook
In MAN mode, the operator can decide which breaker must be opened or closed and can
interacts with the controller with the manual opening and closing commands.
Manual opening commands are accepted only if at least one digital output of the controller is
configured as “opening command”.
Manual closing commands are accepted only if at least one digital output of the controller is
configured as “closing command”.
Three types of commands are provided:
•
Using the controller buttons.
The keyboard has only one button (GCB) for opening and closing the circuit breakers. If
pressed while the circuit breaker is opened, it commands its closure. If pressed while the
circuit breaker is closed, it commands its opening. The button can act on all circuit
breakers:
o
If pressed as a single button, it opens/closes the GCB circuit breaker.
o
If pressed together
with SHIFT button from the display pages M.02 … M.04, it
opens/closes the BCB circuit breaker.
o
If pressed together with SHIFT button from the display page M.09, it opens/closes
the LCB circuit breaker.
o
If pressed together with SHIFT button from the displ
ay pages M.10 … M.12, it
opens/closes the ACB circuit breaker.
•
Using the digital inputs of the controller (to connect external buttons to allow for manual
opening/closing of the breakers) The following functions are available:
o
Function DIF.1001
– “Request for GCB closure”.
o
Function DIF.1002
– “Request for GCB opening”.
o
Function DIF.1031
– “Request for ACB closure”.
o
Function DIF.1032
– “Request for ACB opening”.
o
Function DIF.1061
– “Request for BCB closure”.
o
Function DIF.1062
– “Request for BCB opening”.
o
Function DIF.1091
– “Request for LCB closure”.
o
Function DIF.1092
– “Request for LCB opening”.
All these commands act on shifting the input from “not active” to “active”, not on the
stead
y “active” state.
For each breaker you can use both commands or just the closing command. If only
the closing command is used, it acts as “toggle”: it commands the breaker opening if
it is closed, or its closing if it is open.
•
Using the commands received from the communication ports. To send the commands you
need to write in sequence (within 5 seconds):
o
HOLDING REGISTER 101: enter the password configured with the parameter
P.0004.
o
HOLDING REGISTER 102:
▪
31 and 32 to open the GCB.
▪
33 to close the GCB.
