Limit Setting and Direction Check
For jobs with both front and rear doors, separately adjust the door operators.
1. Turn OFF, Lock, and Tag out the mainline disconnect.
2. Verify that the door card is 6300PY1, and the U4 software is 675HA_. See Figure 6 on page 15
for the remaining steps in this procedure.
3. Manually move the door to the Fully Closed Position, noting which direction the cam shaft
rotates.
4. Loosen DCL and DOL Cams, and rotate them until their magnets face the door card.
5. Loosen the door card mounting bracket screws.
6. Slide the door card and bracket toward or away from the DCL and DOL Cams until there is 1/8"
between the card and the cams. The card must be square with the DCL and DOL Cams.
7. Tighten the door card mounting bracket screws.
8. Slide the DCL and DOL Cams to align the center of their magnets with the center of their
respective magnetic sensors at the edge of the door card.
9. Turn ON the mainline disconnect.
To prevent automatic movement of the door while adjusting limit switches, place the
elevator on INSPECTION Operation.
10. Rotate the DCL Cam in the same direction that the cam shaft rotated in Step 3 until the DCL
LED just turns ON. Tighten the set screw.
Note:
When power is turned ON or the door reset button on the door card is pushed, the
watchdog LED on the door card should come on for 2 seconds, turn OFF, then come back
ON and remain ON.
