4-36 Initialization Mode
Switches 1 and 2 – Top-stop Angle Range
Options switches 1 and 2 control the range of angles within which the Top-stop “On” Angle
falls (see Installing the Overrun Sensor Magnet, page 2-82). WPC 2000 uses these switch
settings to determine at what angle to begin the overrun sensor closure test, which is used to
make sure that the overrun limit switch closes at the same angle on every stroke. Settings for
option switches 1 and 2 are shown in Table 4-5.
Switch 3 – One-hand Control and Foot Switch Settings
When you have optional One-hand/Two-hand/Foot firmware, option switch 3 provides
settings for a One-hand Control or Foot Switch. Switch 3 enables Light Curtain Break mode
in a One-hand Control when “ONE HAND” is highlighted on the Mode Select Menu (see
page 6-40). Switch 3 enables either Foot Trip or Foot Control in a Foot Switch when “FOOT”
is the selected mode.
ENABLING LIGHT CURTAIN BREAK MODE IN A ONE-HAND CONTROL
When “ONE HAND” is highlighted on the Mode Select Menu, switch 3 controls the
conditions under which a One-hand Control (see Installing a One-hand Control, page 2-39) is
active, as shown in Table 4-6.
When switch 3 is set to OPEN, the One-hand Control is continuously active, allowing you to
initiate a stroke any time you push the One-hand Control switch.
When switch 3 is set to CLOSED, the One-hand Control is active only during the window
within which the operator breaks the light curtain to feed a part and for eight seconds after his
hand has cleared the light curtain. This condition is called Light Curtain Break mode. If the
operator presses the switch after this window has expired, the press will not start. The light
curtain must be broken again before the next stroke can be initiated.
