MCD Bus Options – General Notes

•

•

All bus options have the ability to:

Control the soft starter

Monitor the soft starter status

•

•

•

Monitor the soft starter trip state

Monitor the soft starter current (not available on MCD 201)

Monitor the soft starter thermal model overload temperature

(not available on MCD 201)

Parameters can also be uploaded to or downloaded from MCD 500 soft starters on Modbus, DeviceNet or Profibus networks.

In order for the MCD 500 to accept commands from the serial network, the soft starter must be in Auto On mode and links must be fitted to terminals 17 and 25 to 18. In Hand On mode, the starter will not accept commands from the serial network but the starter’s status can still be monitored.

The following information is a general guide to MCD 500, MCD 3000 and MCD 200 bus options. Refer to the relevant installation instructions and users manual for more detail.

MCD 200 with MCD Remote Operator Option

This requires an MCD Serial Interface Module which clips onto the side of the MCD 200. It is supplied with the MCD Remote Operator when ordering Cat. No: 175G9004.

Notes

• A single MCD Remote Operator and MCD Serial interface Module is required for each MCD 200.

•

•

No set-up or confi guration is required for operation.

If two Remote Operators are required, the RS485 Network side of the fi rst Remote Operator (terminals B6, B7, B8) must be connected to the

RS485 Starter side of the second Remote Operator (terminals B1, B2,

B3). The fi rst Remote Operator is ordered using Cat. No: 175G9004 and the second Remote Operator is ordered using Cat. No: 175G3061.

• The Serial Interface Module is powered by the MCD 200. The Remote

Operator requires an external 18-30 VAC/DC auxiliary supply.

• For more information on the MCD Remote Operator, refer to the User

Manual (MG.17.Ex.02)) located at www.danfoss.com/drives.
