1. General remarks
1.1. Valve outputs
Before starting
the diagnostic program it is required to check if the hydraulic pump of the
pressbrake is not running. This is because during the diagnostic operation of the control no
regulation of the pressbeam is performed.
With the diagnostic program you have to be very careful because the proportional valves can
be deflected. The height-retaining valves have to be in the closed position in order to prevent
the top beam coming down. It is good practice to place the top beam in its lowest position
before starting the diagnostic program.
1.2. Components check
In the description of the tests it is indicated which component(s) is(are) responsible for
correct functioning of that particular part.
See for exploded view drawing with all internal cables and cards of the DA-52s controls the
included diagrams at the end of part I.
