Appendix A - Modbus Control via Remote Operator
11.7. Using the Remote Operator with MCD 3000
In order to operate correctly on the network, the MCD 3000 must be set for local operation only (i.e.
set Parameter 20 = 2). The Remote Operator's default communications protocol setting is AP ASCII.
This must be changed to Modbus RTU.
The RS485 Network Timeout setting on the Remote Operator applies to the link between the Remote
Operator and the network. This can be set to any value between 0 and 100 seconds.
The Serial Timeout setting on the MCD 3000 (Parameter 24) applies to communications between the
Remote Operator and the MCD 3000. See the MCD 3000 Operating Instructions for soft starter
configuration details.
11.8. Programming
The Remote Operator must be configured to operate on the network. In order to access
Programming Mode, the Remote Operator must be powered up when the soft starter is not running.
11.8.1. Programming Procedure
1.
To enter Programming Mode, hold down the Data/Prog pushbutton for four seconds. The
default value of the first parameter will be displayed.
2.
Use the Data/Prog pushbutton to advance to the next parameter.
3.
Use the Stop/+ and Reset/- pushbuttons to adjust parameter values.
Programming Mode closes when the Data/Prog pushbutton is pressed after Parameter 8.
N.B.!:
There is a 20 second timeout when the Remote Operator is in Programming Mode.
Programming Mode will automatically close if no input is registered for 20 seconds. Any
changes already made will be saved.
