Automatic Soft Stop Amps Threshold (PSIO Software Version 09 and Higher)

The SOFT STOP AMPS THRESHOLD closes the guide vanes of the compressor automatically when a non-recycle, non-alarm stop signal occurs before the compressor motor is deenergized.

If the STOP button is pressed, the guide vanes close to a preset amperage percent or until the guide vane is less than 2% open. The compressor will then shut off.

If the machine enters an alarm state or if the compressor enters a RECYCLE mode, the compressor will be deenergized immediately.

To activate SOFT STOP AMPS THRESHOLD, view the bottom of Service1 table. Set the SOFT STOP AMPS THRESHOLD value to the percentage amps at which the motor will shut down. The default setting is 100% amps (no Soft Stop).
