Adjusting Fully Open Upper Door Limit Switch
When triggered the Fully Open Upper Door limit switch enables the arm operation (see Figure
3-48). If the upper door is not fully open and properly latched, the operator cannot operate the arm.
This lockout function is provided to prevent the arm from colliding against the upper door.

This switch is located on the right middle side post.
If the automated arm function cannot be activated by the operator despite of the fact that the upper
door is fully open, an adjustment of the Fully Open Upper Door limit switch may be required.
To adjust the Fully Open Upper Door limit switch:
1. Unscrew the lever adjustment screws of the limit switch (see Figure 3-45).
