parameter sets
Additional Control Applications

The MICROMASTER 420 can also be controlled by the following means: Digital inputs/ Analogue inputs
Serial Link via USS Protocol
Automated system via PROFIBUS connection
Changing single digits in Parameter values

For changing the parameter value rapidly, the single digits of the display can be changed by performing the
following actions:
1 Ensure you are in the parameter value changing level (see” Changing parameters with BOP”).

2 Press (function button),this causes the right-hand digit to blink.
3 Change the value of this digit by pressing /.
4 Press (function button) again causes the next digit to blink.
5 Perform steps2 to 4 until the required value is displayed.
