Adjustable Settings

The MPA settings can be reviewed and/or adjusted by selecting the 'MPA Settings Information' Page, Level 7. At

this level all the adjustable parameters are listed with their current value.

Although settings are available in both cases, the Modbus settings will not function on

a Motor Protection Relay if it is supplied with the Ethernet option, and the Ethernet

settings will not function if the relay is supplied with the Modbus option.

16.1
