Digital ("D") Control Description:

The Digital ("D") control system controls the desired pressure, speed and dwell time, and displays the press status. The following features are included with the Digital ("D") version:

Ten (10) recipe storage of pressure and time settings
Digital control of pressure and dwell time
Digital pressing speed adjustment
Adjustable end of cycle alarm
Auto opening of platens upon cycle completion
Units of measure setting for KG, lbs or US tons
Optional manual cooling

The normal operating cycle consists of closing the press with the dual "anti-tie-down" buttons and building force to the selected setpoint for a predetermined dwell time, and eventually opening the press after the integral has expired.

Programmable ("P") Control Description:

The programmable ("P") control system includes all the features of the "D" control system plus allows for step programming of segments, or events, throughout the cycle. The following additional features are included.

Twenty (20) programmable segments per recipe
Ten (10) recipe storage of temperature, pressure and time settings
Optional automatic water cooling and air purge

The normal operating cycle consists of closing the press with the dual "anti-tie-down" buttons and building force to the selected setpoint of the first segment of the recipe, maintaining this setpoint for the dwell time specified for that segment; repeating this cycle of building or maintaining force for the other segments, and eventually opening the press.

Platen temperature can also be adjusted for each segment of the recipe as part of the "Programmable" control system.
