Setting Option Switches on S102
This section shows you how to make settings on option switches 2 and 6 on switch block S102
on the WPC 2000 Main Processor board (see Figure 2-14, page 2-28 for location). All eight
S102 switches are factory-set to the OFF position. Only switches 2 and 6 are active. To set a
switch to ON (see Figure 4-24), push up on the switch with a small screwdriver or your
fingernail.
Switch 2 – Auxiliary E-Stop Relay Muting Function
The Auxiliary E-Stop Output Relay board is an optional “daughter” board that enables up to
three auxiliary devices (e.g., feeds, transfers, etc.) to be stopped, or prevented from starting,
when one of three conditions exist: activation of an E-stop button, penetration of a light
curtain, and an “open” state in a cross-checked input.
Option switch 2 allows the Auxiliary E-Stop Output Relay board to be muted when a light
curtain is penetrated during the muted portion of the stroke (see Table 4-13). The switch is
functional only when your WPC 2000 has optional Shadow muting firmware, which disables
the light curtain during the portion of the stroke after the Auto Carry-up Angle has been
reached (see Setting the Auto Carry-up Angle, page 4-28).
When switch 2 is set to OFF, its default setting, muting of the Auxiliary E-Stop Output Relay
board is disabled, and penetration of the light curtain at any point in the stroke causes a stop
command to be sent to auxiliary devices. When switch 2 is set to ON, the Auxiliary E-Stop
Output Relay board is muted during the portion of the stroke when the light curtain is muted.
Switches 1, 3 through 5, 7, and 8 on switch block S102 are not used.
