Diagnostics of phase failure
VSD is ready
VSD has voltage applied to all input phases
(3 or 6, 9 depends on pulses)
and it is in the range of 380/480 + 10% -15%
Check that the power is supplied to all networks and it corresponds to the
following values: 380/480 + 15% -15%. If there is no 6-phase power supply,
connect 1 network in parallel with the second one using jumpers of the
corresponding cross section.
Not
Check that the controller has entered a value for
working with 3 networks
In the UMKA07 controller menu go to the «Creating» life cycle , select the
«Drive setting » submenu, the «Rectifier configuration» parameter must be set
to «18-pulse», set the values mentioned above
Connector P8(XP2) of BVN unit and connector to
P7 (XP8) of GB unit
is installed according to the key and latched
Turn the VSD OFF, open the VSD using the supplied key. The P8(XP2)
connector of BVN unit must be inserted and locked. The P7 (XP8) connector of
GB unit must be inserted and locked.
The circuits going to the BV-6 block, which is
installed in the rectifier cell, are working
Turn the VSD OFF, open the VSD using the supplied key. Remove power from
the control system. Using the tester, ring the circuits: from phase R1 through
the CB1(QF1) circuit breaker to the
ХP12:16 connector of BVN unit. If the
circuit is broken, restore. Repeat for phase S1 - there must be a connection to
ХP12:4 of unit BVN. If the circuit is broken, restore. Repeat for phase T1 - there
must be a connection to
ХP12:12 of block BVN. If the circuit is broken,
restore.Repeat the steps for the second and third networks.

The BVN unit is operational
Turn the VSD OFF, open the VSD using the supplied key. Replace the BVN
unit after disconnecting connectors. Then, unscrew the fixing bolts, replace
BVN unit with a working one in the reverse order from the removal process.

Connectors P68 of BVN1 unit connected
to P58 terminal of RMPS unit.
Turn the VSD OFF, open the VSD using the supplied key. Remove power from
the control system. The P68 connector of BVN1 unit on the rectifier panel
must be inserted, locked and connected to P58 terminal of RMPS unit.
Connectors P70 of BVN unit connected
to P58 terminal of RMPS unit.
Turn the VSD OFF, open the VSD using the supplied key. Remove power from
the control system. The P70 connector of BVN2 unit on the rectifier panel
must be inserted, locked and connected to P58 terminal of RMPS unit.
Connector P15 of BVN1 unit and connector P23
of BVN2 unit is installed according to the key and
latched
Turn the VSD OFF, open the VSD using the supplied key. The P15 connector
of BVN1 unit must be inserted and locked. The P23 connector of BVN2 unit
must be inserted and locked.
