CHAPTER 3: FEEDBACK
Feedback Setup allows the configuration of analog inputs (sensors) and other feedback sources.
• Control Feedback Sources: Select the number of feedbacks that are used to
controlling the process variable. The feedbacks referred to are for control, not
for monitoring.
• Feedback 1 Source: The effective feedback signal is made up of up to three
different signals. Select which drive input should be treated as the source of the
first of these signals. Be sure to properly set the configuration switches A53
and A54 behind the keypad. Switch set to “I” for mA transducer; switch set
to “U” for voltage transducer”.
• Terminal 53 Low Reference
• Low Feedback 1 Value: Enter the minimum feedback value
(in psi, GPM, feet etc.).
• High Feedback 1 Value: Enter the maximum feedback value
(in psi, GPM, feet etc.).
• Feedback 1 Sensor Fault: If enabled, Sensor Fault will display a fault when
sensor voltage or current drops to less than 50% of the minimum value
programmed for that input.
AUTOSET
For basic applications, users are able to set motor information, operation mode and “Autoset” the rest of
the parameters. With support for the most common control configurations, the Genie reduces setup and
configuration time to less than 15 minutes. Autoset parameters vary with application type.
