ABB Industrial Drive BAMU-12C auxiliary measuring unit

Hardware description

The BAMU-12C Auxiliary measuring unit is a measuring unit for the accurate measurement of voltage and current. The unit has:

• Two three-phase voltage inputs

• Three current inputs

• LED indicator

• 24 V DC supply voltage

• Fiber optic link for communication with the upper frequency converter control unit.

compatibility

The measuring unit is compatible with the BCU-02, -12 and -22 control units. The control unit must also be equipped with a control that can communicate with the measurement unit

System procedures, such as IGBT power supply control procedures.

arrangement

Install the module in a cabinet/compartment in an indoor environment. Leave enough space for wiring. Make sure the temperature is not too high.

Do not install measuring units such as relays, contactors, brake choppers, power supply and motor cables near electromagnetic interference sources

Close. The minimum recommended distance from such parts is 200 mm (7.9 in). We recommend installing between the measuring unit and the source of interference

Install metal shielding. This shortens the distance required.

Install the control unit so that air can pass freely through the vent holes in the housing. Do not install directly on the heating device.

Mechanical installation

1. Install standard 35 × 7.5/15 mm DIN guide rails on the cabinet where the unit is to be installed.

2. Secure the two latches to the back of the measuring unit with four screws.

3. Connect the measuring unit to the guide rail as shown below.

4. Ensure that the guide rail is properly grounded through the assembly plate or the separate ground cable. The unit is grounded through a guide rail.

■ Communication link connection (V30)

Transmitter V1T, receiver V1R

Optical Fiber Communication Link: Avago Versatile Link Series optical transmitter and receiver, DC-50 MBd (50 Mbd/s)

■ Connect to the BCU control unit

Connect the BAMU-12C auxiliary measurement unit to the first unused channel of the BCU control unit via fiber optic cable.
