No input voltage indication (or it does not match)
VSD is ready
VSD is on and the screen displays the current
mains voltage
The controller displays output voltage values.
Not
Check that the adjusted voltage value is entered in
the controller
In the UMKA07 controller menu, go to the
«Testing» life cycle, select the
«Input parameters» submenu, the value of the parameter «Uin adjusting
factor
» must be set to 600 on the first network, the value of the parameter
«Uin adjusting factor» must be set to 600 on the second network, the
value of the parameter
«Uin adjusting factor» must be set to 650 on the
third network. After which the display of the input voltage must be correct.
The voltage measured by the controller is close to
real but there is a difference of a few percent
In the menu of UMKA07 controller, go to the
«Testing» life cycle, select
the
«Input parameters» submenu, measure the values between terminals
R1 and S1 and enter the received values in the
«AB input voltage»
column, and then check how the calibration coefficient changes. Repeat
all the steps for other phases
The circuits going to the BVN block installed in the
rectifier cell are working
Turn the VSD OFF, open VSD using the supplied key. Turn off the power
to a VSD by disconnecting power cables. Using the tester, ring the
circuits: from phase R1 through the CB1 circuit breaker to the rectifier
block to the connector of BVN block. If the circuit is broken, restore.
Repeat all the steps for other phases
Not
Yes
Not
The ribbon cables of the BVN unit installed in the
rectifier cell are inserted and the latches are
locked
Turn the VSD OFF, open VSD using the supplied key. Check that the
ribbon cable coming from the BVN unit the is securely inserted. To
check, separate the latches and remove the cable. Then, insert it into
socket and make sure that the latches click into place. Repeat the same
procedure with the similar cable in the IDC16 connector of the GB unit.
Not
There are power supply voltage at P60:16,
P60:12, P60:4 P59:16, P59:12, P59:4 terminals of
BVN unit.
Turn the VSD OFF, open VSD using the supplied key. Turn off the power
to a VSD by disconnecting power cables. Replace the BVN unit.
Not
Not
Turn the VSD OFF, open VSD using the supplied key.
Disconnect the connectors from GB unit, having photographed
their positions before dismantling, unscrew the GB unit from the
VSD. Install the working GB unit in the reverse order from the
dismantling, connect the connectors as done previously. Close
VSD, move the circuit breaker to the ON position.
