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-2-TS board is ON and the LCD display indi-
cates 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. Hydraulic elevators are usually set up to open the
doors only after the car stops, but pre-opening is available. 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 fail to open on the first attempt, they will make two
more attempts. Each attempt will generate a fault message, Door open fail 1 (2/3). If
the doors are still unable to open, a door open fault will be declared. The door open fault is
cleared by a successful door opening cycle or by pressing the Fault Reset button.
• Door close protection: If the doors fail to close on the first attempt, they will make two
more attempts. Each attempt will generate a fault message, Door close fail 1 (2/3). If
the doors are still unable to close, a door close fault will be declared. The door close fault is
cleared by a successful door closing cycle or by pressing the Fault Reset Button. If the door
close fault continues, a door close fault shutdown will occur. The car doors will fully
reopen, all calls will be canceled, and the car will shut down.
