7.1.7. Circuit breaker control card
N.B.
Changing the settings by means of dip-switches must be carried out with the control
module de-energised and the capacitor discharged since the selections set and/or modified
are acquired by the control electronics at the moment it is turned on.
Connector for the
storage capacitor/s
and the actuator coils
Power supply
connector
Connector for:
- closing pushbutton
- opening pushbutton
- luminous “READY” signal
Connector for input signal of
the circuit breaker
open/closed position sensors
Jumper only present in the full
option version.It is not normally
short-circuited and energy
consumption during capacitor
charging is 100 W.If it is short-
circuited, energy consumption
during capacitor charging is
reduced to 50 W (the charging time
is obviously doubled)

) Full Option version.
(

) If enabled, the SO3 input behaves like a hardware input operation even when there is a
fault in the microprocessor. If disabled, the –SO3 input behaves like a digital opening
input processed by the microprocessor.
Selector not used for the VM1 circuit breaker
