Parameters Explained - Maguire Products VBD-150 Installation Operation & Maintenance

VBD® - Vacuum Dryer®
Parameters
All Maguire VBD controllers operate according to certain internal PARAMETERS.
Because customer requirements vary widely, we have made parameters accessible for
change through the keypad. In most cases, these parameters will never need to be
changed. Some parameters that are routinely adjusted values are adjustable from the
main display. To access and edit the parameters, see Changing Parameters in this
section:
Changing parameters can have an impact on the Dryers performance. It is highly
recommended that a supervisor change the default Program Mode password to protect the
values. Prior to making any changes, make sure you understand what you are doing. If in
doubt contact a Maguire Dryer Technician before making changes to your dryer.
