Startup Chapter 3
The precharging of the unit automatically starts when input power is
present. When the DC Bus Voltage reaches its nominal value, the
circuit breaker automatically closes.
To stop the AFE, turn the 0-1-START switch to 0 (off ).
2.
MAN
– Manual operation by the 0-1-START switch on the enclosure
door.
a. Set the MCCB CONTROL switch to MAN.
b. Turn the 0-1-START switch to START and let it automatically
return to 1.
The precharging takes about 5…10 seconds depending on the
connected DC bus capacitance. When the DC bus voltage has
reached its nominal value, the AFE control automatically closes the
circuit breaker.
The precharging can be aborted by turning the switch to 0 (off ).
To stop the AFE, turn the 0-1-START switch to 0 (off ).
3.
REM
– Remote operation with signals to the control terminals.
a. Set the MCCB CONTROL switch to REM.
b. Connect a normally closed (NC) contact to terminals X1:58 and
X1:61.
This contact has to be in the NC-state for the AFE to precharge and
run. A remote pulse of 0.4…1.0 seconds duration, connected to
terminals X1:57 and X1:60, starts the precharging of the AFE. When
the DC voltage has reached its nominal value, the AFE unit
automatically closes the circuit breakers.
IMPORTANT
Pressing the (Stop) key on the HIM only stops the AFE
output—it does not open the MCCB to stop the AFE.
When a voltage drop or a blackout occurs in the supplying network,
the unit precharges automatically and closes the circuit breakers
when the main supply voltage returns.
IMPORTANT
Pressing the (Stop) key on the HIM only stops the AFE
output—it does not open the MCCB to stop the AFE.
When a voltage drop or a blackout occurs in the supplying network,
the under voltage release coil opens the circuit breaker. To turn on
the AFE, turn the 0-1-START switch to START and let it automatically
return to 1 (on).
