What to do if the purge cycle does not start on my Pepperl+Fuchs 7500 Control Unit?

  If the purge cycle isn't starting, several factors could be at play. First, ensure that the system is receiving air and that the minimum pressure requirement is met. If the control unit is in dust mode, inspect the vent and enclosure seals, and verify the compensation valve setting. Also, make sure you're using the correct program (programs 1-4) instead of program 5.

  The purge cycle might not initiate due to several reasons. Check that the air supply is connected and provides sufficient minimum pressure. If the unit is in dust mode, examine the vent and enclosure seals, and check the compensation valve's setting. Also, make sure you're using the appropriate program (1-4) and not program 5.

  To resolve a non-starting purge cycle, begin by checking the air supply to confirm it's connected and meets the minimum pressure requirements. Then, if the control unit is in dust mode, inspect the vent and enclosure seals, and verify the setting of the compensation valve. Finally, ensure you are using the correct program (programs 1 through 4) instead of program 5.
