Figure 4.22 Mixer with Preset Slow Speed Option

Problem: A mixing process required a soft start to prevent damage

to the mixer, as well as meet the local power requirement

for reduced voltage starting. Running the machine at

slow speed on start-up to ensure it was not binding was

desirable. The mixer would then be run at full speed.

Solution: The SMC Dialog Plus controller with the Preset Slow

Speed option was installed, allowing the mixer to be

jogged at slow speed to ensure there was no binding. The

SMC Dialog Plus controller was then set for a 22-second

soft start to meet the local reduced voltage requirement.

The Energy Saver was activated for slack production

periods. This allowed for greater control of the moto

without the expense of a variable frequency drive.
