Final Adjustments on Independent Service
The following final adjustments should be performed with the elevator operating on Indepen-
dent Service.
•Place the CONTROLLER TEST SW on the HC-CTL-2 board in the NORM position.
• Place the Independent Service switch in the IND position.
• Verify that the IND indicator on the HC-MPU board is ON and the LCD display indicates
INDEPENDENT SERVICE.
Door Operator Adjustments
Complete the final door operator adjustments. Verify smooth opening and closing. Doors can be
opened at 3" before the floor or at the floor (see “PRE-OPENING?” on page 5-23). Hydraulic
elevators are usually set up to open the doors only after the car stops, but pre-opening is avail-
able. Verify the operation of the photo eye and/or safety edge, door open and close buttons.
Door Open/Close Protection
Verify proper door open protection and door close protection operation.
• Door open protection: If the doors do not open (DOL goes low) after several seconds, the
car will give up and continue to the next call (see “DOOR OPEN PROTECTION TIMER”
on page 5-27).
• Door close protection: After the car starts to close the doors and the doors do not lock, it
will recycle the doors open and attempt to close the doors three times before a DLK fail
error is generated and DOOR CLOSE PROTECTION TIMER ELAPSED is displayed on the
LCD.
