As the lift approaches the bottom floor, the binary lane on the vane will tell the lift to
DECELERATE, as soon as the opto-reader or switch reads the lane or cam. If the
deceleration is set too short, the lift will reduce its speed to leveling speed in a rough, jerky
manner and remain in leveling speed for excessive time. If the setting is too long, the
DECELERATION may take the lift directly to the floor with no slowdown (or even past the floor
level). The ideal length of slowdown is about 4" to 5" (102 mm - 127 mm), depending on
speed of lift and length of cams or vanes. If the deceleration is too long, then the transition
from high speed to leveling speed (deceleration) must be adjusted.
• To set the deceleration, first press the LEARN button while the display indicates F4 to
observe the current setting. To reduce (or make harsher) the deceleration, the F4
setting must be increased. Check the deceleration again and note if the number must
be reduced or increased in order to provide a smooth approach to the floor. (When
satisfied with the performance of the valve, return the TEST switch to the NORMAL
position.)
• The DOWN direction settings have been completed.
• The adjustment of the UP direction settings is identical to the DOWN direction settings
with the exception of the F0 setting. Follow the procedures to place the processor in
TEST mode and change the display to F0. Using the temporary buttons, start the lift
in the UP direction at high speed. If there is any appreciable delay in the time
between when the motor starts and the lift starts to move, the F0 function must be
changed. Note that “appreciable delay” means any time beyond two seconds. As with
all adjustments, a higher number means longer delay time and a lower number means
shorter delay time.
• The UP direction full speed adjustment, function F3, should be set between 88 or 96.
This opens the solenoid fully, and the full amount of the oil produced by the pump and
motor will go straight to the jack assembly. It is possible to reduce the full UP speed
by entering a lower number for F3, but this is currently not recommended practice.
• With the adjustments for UP and DOWN completed at the terminal landings, the
technician can now install the vanes or cams at the intermediate landings. It should
not be necessary to further adjust the valve settings. Simply ensure that the vanes or
cams have been placed at each intermediate landing. The valve should automatically
slow down and stop level at each intermediate landing.
AUTOMATIC CAB LIGHTING
This feature automatically turns the car ceiling lights ON and OFF through the control circuitry.
It is not necessary to add a light switch or key switch to control the lighting. The features and
sequence of operation are as follows:
1) CALLING THE ELEVATOR FROM LANDING CONTROLS
Upon pressing the call button, the car lights will automatically come ON when the elevator
starts to move. The car will arrive at the landing with the car lights ON.
