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 the Mode Select switch is set to “1 HAND.” Switch 3 enables
either Foot Trip or Foot Control in a Foot Switch when the Mode Select switch is set to
“FOOT.”
Enabling Light Curtain Break Mode in a One-hand Control
When the Mode Select switch is set to “1 HAND,” switch 3 controls the conditions under
which a One-hand Control (see Installing a One-hand Control, page 2-43) is active, as shown
in Table 3-5.
When switch 3 is set to OFF, 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 ON, 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.
Enabling Foot Control in a Foot Switch
When the Mode Select switch is set to “FOOT,” switch 3 controls how the Foot Switch must
be activated in order to initiate and complete a stroke, as shown in Table 3-6, page 3-28.
Switch 3 Foot Switch settings apply only to Single-stroke operation.
When switch 3 is set to OFF, the Foot Switch is in Foot Trip mode, which requires only that
the operator depress the Foot Switch, without holding it down, to initiate and complete a
stroke.
