• The in-car stop switch or emergency stop switch is inoperative while the car is in motion.
• Doors do not open automatically at any floor except the main floor or alternate level.
• Power-operated doors can only be opened by continuous pressure on the door open button,
and if released before the doors are in the normal “OPEN” position, the doors will close
automatically without delay.
• Fully open power-operated doors can only be closed by the use of an in-car close button.
• If two entrances can be opened and closed at the same landing, separate door open and close
buttons are provided for each entrance.
• All door reopening devices are inoperative (except the door open button). Full speed closing is
permitted.
• “CALL CANCEL” button is labeled and when activated, will cancel all calls and cause the car to
stop at or before the next available landing.
• Floor selection buttons are provided and functional for all landings without restrictions.
• Moving car will stop at the next landing with a car call registered and remaining car calls will be
canceled.
Make sure the Phase II operation cannot be deactivated after it has been activated. Turn the main
floor key to the ON position, and the in-car switch to ON. Take the car to any floor. Turn the main
floor
key to the OFF position, or if a smoke detector is activated to the
BYPASS position and make
sure the Phase II operation is maintained until the car is returned to the main floor.
Place a car call above the main floor and while in motion press the “Call Cancel” button and verify
that all calls are cancelled and the car stops at or before the next available landing.
Turn the main floor switch to the OFF position, or BYPASS if a smoke detector is activated. Take
the car to a floor above the main floor and turn the in-car switch to the ON position. Make sure the
Phase II operation does not operate even if the main floor switch is in the ON position or a smoke
detector is activated.
To test the alternate level, turn the main floor key operated switch to the OFF position, and activate
the smoke detector. If the smoke detector at a designated level is activated, the elevator should
return to an alternate level designated by an enforcing authority unless the Phase 1 switch is
activated. Make sure the car returns to the alternate level.
To test the HOLD feature, place the car on Phase II with the key switch in the HOLD position and
remove the key. Verify the car remains at the landing and the door close button is inoperative.
8.6.4.19.7: STANDY- BY EMERGENCY POWER
Category 1 testing of stand-by (emergency power)
NOTE: Testing of stand-by (emergency) power is performed with NO LOAD in the car.
If a stand-by (emergency) power switch is installed, run the elevator to the floor where that switch is
installed. Remove elevators (s) from normal service and transfer the system to stand-by power to
operate the car(s) with no load. Test the switch which overrides sequence operation, if one is
provided. To do this, make several trips and stops, and use a tachometer in the machine room to
check the speed of the car(s). Make sure the elevator is running at normal speed (particularly in the
up direction). The speed must not exceed 125% of the rated speed.
If a separate power absorption means is used to absorb regenerative power, such as a resister
bank, it must be connected on the load side of the elevator. If more than one elevator is designed to
operate
from the same power source simultaneously, test their
simultaneous operation.
