7b.1 Final System Checks Prior to High Speed Adjusting
1. Verify that all safety circuits are operative and that each device in the string will prevent
the car from starting or continuing to run.
2. Verify that all hoistway door interlocks function properly both electrically and
mechanically.
3. Verify that hoistway access circuits function according to your local applicable codes.
4. Verify that the car gate is set and functions properly according to local applicable
codes.
5. On inspection, run the car to both extreme limits of travel to insure there is adequate pit
and overhead clearance for both the car and counterweight in the event the car or
counterweight should go onto their buffers during the initial adjustment process.
Verify that the car to counterweight is correctly balanced to no less than 40% and no
6.
more than 50% of full rated capacity of the car.
Set the up and down directional limits to open when the car is 1" beyond floor level at
7.
the top and bottom terminal floors.
Set the final limits to open when the car is 6" beyond floor level at the top and bottom
8.
terminal floors.
Verify the power wiring on the encoder electronics power supply and insure the D8 LED

is on continuously on the encoder electronics board.
While riding on the car top on inspection, verify as the car travels up past the last top
10.
terminal slowdown that the D5 LED on the encoder electronics board turns on. If it does
not, check the terminal slowdown wiring to the limit board and to the encoder
electronics board.
11. While riding on the car top on inspection, verify as the car travels down past the last
bottom terminal slowdown that the D6 LED on the encoder electronics board turns on.
If it does not, check the terminal slowdown wiring to the limit board and to the encoder
electronics board.
