A. Door Zone Sensor / Door Zone Actuators Fitted At Each Floor Level.
a. Ensure Door Zone Actuators (DZA's) are fitted at each flr lev and operate the Door Zone Sensor
(DZS) fitted on the lift car. Also the DZA's are clear of any obstructions of the lift car and DZS.
b. Also ensure the signal from the Door Zone Sensor can be seen in the lift controller. This can be
achieved by pressing MAIN MENU then LIFT/GROUP VEIWER on the Almega keypad which
will display the screen as Figs 6/7 below:

B. Motor Wiring / Speed
a. Ensure motor windings and valves are wired correctly. Ensure the motor runs at the correct /
expected speed when on Inspection, Normal and Level Speed. E.g. for 0.3m/s, the Almega LCD
display will show "S = 0.30", and is the actual measured speed.
C. Almega Parameters
a. TRAVEL SETUP

b. POSITIONING SYSTEM SETUP (Press Menu-> PARAMETERS->POSITIONING SYSTEM SETUP)

D. Slowing Limits
a. Ensure slowing limits are set as the backup slowing distances (BSD) as below. (Also see shaft
wiring drawing). Setting the distance too great may generate events "SLOWED: UP/DN SLOW
LIMIT" and result in inaccurate floor levels at the terminal floors!
b. Speed (m/s) BSD (mm)
0.2
0.5
0.75
E. Overspeed Governor Encoder (if fitted)
a. Ensure Correction Sensor/Points are firmly fixed and cannot move. Also central to floor level.
b. Ensure the encoder coupling to the OSG is fitted correctly and all the grub screws are tightened.
