Digital Input And Relay Output Terminals - ABB ACS800-07-0610-3 Hardware Manual

Digital input and relay output terminals

The DSU can be controlled through two control interfaces: local and remote. The
operation switches placed on the cabinet door are connected to the local control
interface. The remote control interface can be used in parallel when control by other
external devices is needed.

1)
After the power switch-on, the DSU first charges the contactor control
capacitors (~ 3 s at first start) and checks the fault status. DSU starts rectifying
only after the contactors are closed by the START input.
2)
These DSSB board terminals are wired to a separate terminal block to which
the user connections are to be made. See the circuit diagrams delivered with the
unit.
0 -> 1: DSU closes main contactors and starts rectifying.
Note: Local ON input must be switched on.
1)
1: DSU is rectifying. 0: DSU stops rectifying and opens
contactors.

2)
1)
1: DSU is rectifying. 0: DSU stops rectifying and opens
contactors. Note: If start command was given through local
START input, DSU stops only after local ON input is
switched off.
0 -> 1: DSU closes main contactors and starts rectifying.
Note: Local and remote ON inputs must be switched on.
0 -> 1: Reset
