Top-Stop And Overrun Setting Faults; Overrun Limit Switch Fault - Wintriss WPC 1000 User Manual

1125100

Top-stop and Overrun Setting Faults

Problem: The overrun limit switch has turned on before the Top-stop "On" Angle timing has
turned off. The Top-stop Angle internal dwell is 20°.
Remedy: Check to make sure that the Top-stop "On" Angle has been set correctly and that
the overrun sensor magnet has been installed at the correct angle (see page 3-7). If
settings are correct and the error persists, contact Wintriss Tech. Support.

Overrun Limit Switch Fault

Problem: The overrun limit switch has provided more than one signal to WPC 1000 during a
stroke. The switch should open and close only once per stroke.
Remedy: Check the overrun limit switch installation to make sure that the switch opens and
closes only once per stroke, referring to Installing the Overrun Sensor Magnet,
page 3-7 and the LED map on page 3-36. Check to make sure that the switch is
installed correctly, referring to Installing the Overrun Limit Switch, page 2-25, and
that the magnet is installed at the correct angle. Also, check to make sure that the
magnet is attached using a brass or other non-ferrous screw.
Check the diameter of the shaft on which the magnet is mounted to make sure
there is enough dwell for the overrun limit switch to provide an adequate signal
(see Planning Your Overrun Sensor Installation, page 2-26). An ideal diameter is
4 to 6 in. If the shaft is larger than this, mount the magnet on a shaft with a smaller
diameter.
Check to make sure that the press is not encountering excessive shock and
vibration due to operations such as blanking. If you cannot resolve the problem,
contact Wintriss Tech. Support.
