Adjusting Fully Open Upper Door Limit Switch
When triggered the fully open upper door limit switch enables the arm operation (see Figure 3-31). 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.
Figure 3-31 Fully open upper door limit switch
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 adjustement screws of the limit switch (see Figure 3-30).
2.
Raise or lower the detection lever a little bit and tighten up the screws.
The detection lever must touch the side of the upper door for the switch to be triggered.
3.
Test the operation.
The automated arm should be working fine when the upper door is fully open.
4.
Repeat the adjustment procedure if need be.
Adjusting Fully Closed Upper Door Limit Switch (optional)
When triggered the fully closed upper door limit switch (see Figure 3-32) prevents the arm from
colliding against the upper door so that no damage is done to the equipment.
