Installing a One-hand Control
One-hand Control is a switch available from Wintriss that allows operators to use their free
hand to feed a part while their other hand operates the switch. This option can only be used
with WPC 2000 systems equipped with One-hand and Single-stroke modes, employing a
Shadow light curtain to guard the point of operation, and running One-hand/Two-hand/Foot
firmware.
The One-hand Control is mounted on or near the press and allows the operator to cycle the
press without using the Operator Station. To stroke the press, the operator simply pushes the
button as part of his normal hand motion after loading a part.
The One-hand Control can be used in two different modes. In Normal mode, the press cycles
in Single-stroke whenever you push the One-hand Control button. In “Light Curtain Break”
mode, the press cycles only when you push the One-hand Control button within eight seconds
after removing your hand(s) from the light curtain. If the button is pushed after this interval
expires, the press does not cycle.
Light Curtain Break mode prevents inadvertent operation of the press when an operator is
loading or unloading parts.
The mode used for One-hand Control is determined by the setting on option switch 3 (see
Enabling Light Curtain Break Mode in a One-hand Control, page 3-27). When switch 3 is set
to OFF, One-hand Control operates in Normal mode. When switch 3 is set to ON, One-hand
Control operates in Light Curtain Break mode.
INSTALL SAFEGUARDS TO PREVENT ACCESS TO HAZARDOUS AREA
• Follow all applicable OSHA and ANSI regulations for safeguarding your press system. Point-of-
operation safeguarding is the single most important factor in the prevention of injuries.
• Follow all applicable OSHA and ANSI regulations when installing a one-hand control.
• Ensure that proper safeguarding devices are installed and working properly. Wintriss takes no
responsibility if safeguarding devices are not installed or working correctly.
• DO NOT use WPC 2000 or a one-hand control as a safeguarding device.
• Install and operate WPC 2000 and a one-hand control in accordance with OSHA and ANSI
regulations.
Failure to comply with these instructions will result in death or serious injury.
PREVENT OPERATOR FROM STANDING BETWEEN LIGHT CURTAIN AND HAZARD
Ensure that the operator cannot position himself between the light curtain and the hazardous area.
Use another pair of light curtains or a mechanical barrier at knee to waist height to prevent the
operator or a passerby from being “trapped” between the light curtain and the hazard.
Failure to comply with these instructions will result in death or serious injury.
