Description The MX can have three sources of start and stop control; Terminal, Keypad and Serial. Two
parameters, Local Source and Remote Source, select the source of the start and stop control.
If a digital input is programmed as “L-r” (Local / Remote), then that input selects the control source.
When the input is low, the local source is used. When the input is high, the remote source is used. If
no digital input is programmed as “L-r”, then the local/remote bit in the starter control Modbus
register selects the control source. The default value of the bit is Local (0).
Options LED LCD
PAd Keypad When selected, the start/stop control is from the keypad.
tEr Terminal When selected, the start/stop control is from the terminal strip inputs.
SEr Serial When selected, the start/stop control is from the network.
