UBZ-305 NOVATEK-ELECTRO
neutral wire is not connected to UBZ terminal, it is necessary to connect electrically the motor housing to the
terminal
26
of UBZ.
5.2.4
Connect the motor to UBZ in accordance with Fig.5.2. When using the motor with the switching over
the windings during star-delta starting-up, perform the connection in accordance with Appendix
В.
5.2.5
To work with UBZ from personal computer a
s the control or supervising using the program of “UBZ
Control Panel” it is necessary:
–
to install on the PC the program of “UBZ Control Panel”, starting the program
"Setup_cplubz304(Х.Х).exe" (X.X – number of software version);
–
to connect “RS232” connector on the top panel of UBZ to RS-232 connector of PC using the cable KC-01;
–
to set the parameter of
“Communication” = “RS232”.
Notes
:
1) Program
"Setup_cplubz304(Х.Х).exe
"
can be found at website of NOVATEK-ELECTRO Company:
http://www.novatek-electro.com/production_ubz.htm
2) The unit is completed with the cable
КС-01 when ordering. It is possible to manufacture the cable
independently by the user in accordance with Fig.5.12.
3) Programs developed by the user are allowed to be used for operation with UBZ.
5.2.6
In case of MODBUS usage, connect the communication lines to terminals
10 (GND), 11 (line B RS-
485), 12
(line A RS-485)
of UBZ. Set the parameter of
“Communication” = “RS485”.
5.2.7
Energize UBZ
ATTENTION
– UBZ is supplied with set rated current of motor equal to zero. In this case, UBZ load
relay will not be enabled until the rated current of the motor. Motor rated current should be at least 3 A.
The enabling sequence for the load relay after energizing is determined by the values of the parameters
“AR time” and “Start>Power” (it.5.5.1.1).
5.2.8
In the course of first starting in accordance with factory settings UBZ is in the mode of MNS in which it
is possible to set the following parameters:
–
CT rated current (parameter of
“CT nom i“);
–
motor rated current (parameter of
“Rated Inom”).
For normal operation of UBZ it is enough to set these parameters according to used CT and the motor.
5.2.9
Disable power of UBZ;
5.2.10
Connect the magnetic starter (hereinafter referred as MS) of the motor in accordance with Fig.5.2.
Note
– When load relay is enabled, the contacts
4-5
and
7-8
are closed; when relay is off, the contacts
5-6
and
8-9
are closed
