stroke initiation until this is done.

3.

If the press has stopped in the downstroke the present running status will display “Motor
Direction” and the main motor must be switched to Reverse to “back off” the load. If the press
stops after the bottom of the stroke, the press can be Inched only with the motor running in the
Forward direction.

4.

Use the correct run buttons to Inch the press to the top of the stroke. The press control will
automatically stop the press inside the hydraulic overload reset area at the top of the stroke.

5.

The press control will inhibit further stroking at the top of the stroke and automatically reset the
hydraulic overload system by first turning the Cylinder Output (OR-2) On. The present running
status will indicate the status of the overload sensor until input #36 switches high.

6.

Output (OR-3) is turned On (hydraulic overload Reset indicator will light) and the present running
status will indicate that the key switch must be placed in the Normal position until input #37
switches low.

7.

The running status will display “Ready To Stroke” to indicate that the reset sequence is complete
and stroking may be resumed in any mode.

If the Test-Normal-Reset key switch is placed in the Reset position at any time except during a hydraulic
overload fault, the press control will issue a top stop and inhibit further stroking until the switch is
returned to the Normal position. If switched to the Test position, input #36 will open and both outputs
will turn Off. The hydraulic overload system must then be reset as described above.

Section 6.1.13 Light Curtain

The light curtain inputs provide emergency stop signals to the press control, unless muted (ignored) in the
upstroke by the light curtain configuration. These inputs can be configured by the factory to provide
several methods of muting. This programmed information affects the light curtain only in the upstroke,
and an emergency stop is always performed if the inputs open (0 volts) in the downstroke. The
information below describes how the light curtain may be configured:

Light Curtain Type

Conditions when the light curtain is muted

------------------------------------------------------------------------------------------

000

Muted in the upstroke in Inch, Timed Inch

001

Muted in Inch, Timed Inch, and Manual modes

002

Muted in Inch, Timed Inch, and Automatic modes

003

Muted in all modes

004

Light curtain is never muted

005

Muted in all modes. Light curtain inputs are checked in upstroke (requires
a PLS output also be used).

In the Inch and Timed Inch modes, the upstroke and downstroke are determined by the forward and
reverse motor inputs. This affects how the light curtain is muted in the following manner:

Motor Contacts
