ii. Take the lift to the bottom (by bridging the Test Down connections TF and TD). Ensure
not on the mechanical stopping limit (so the bottom floor level is not below the limit!)
iii. Record the bottom floor level. Position Value is found by pressing MAIN MENU then
LIFT/GROUP VEIWER and reading P=????
iv. Take the lift UP to the next floor level, and Record the floor level.
v. Continue until all floor levels have been recorded.

6. ENTER FLOOR LEVELS
Once the levels have been learned / recorded a table will be produced (as Fig1). These need to be entered
into the position system as Fig 3 below. Absolute mode is selected via the option box (GREEN when
selected), otherwise UP / DN adjust is selected.
a.
From the menu POSITIONING SYSTEM PARAMETERS->FLOOR LEVELS, select each floor
in turn and use the selection wheels to adjust the absolute position in millimetres.

7. PUT THE LIFT ON PREPARE TO TEST CONTROL (DOORS OFF)
a.
Press MAIN MENU then ENGINEERS SELCTION, or
i. press MAIN MENU then PARAMETERS then SPECIAL SERVICE2 on the screen.
b. Move the cursor DOWN to highlight "PREPARE TO TEST CTRL"; Press SELECT
c.
Select the Option DOOR OFF.
d. Press OK.
8. ADJUSTING THE LEVELLING TIME (FROM THE CONTROL PANEL) (see Fig 2)
The levelling distance is pre-set at 180mm to allow 3 seconds of levelling at a typical level speed of 60mm/s
(0.06m/s). It is recommended to have at least 3 seconds of level speed to allow the lift to consistently settle
on level speed for differing load / oil conditions, thus maintaining floor level accuracy.
a.
Run the lift UP to a floor (preferably a middle floor to avoid terminal / over-travel limits).
b. Record the time on level speed. If it is more than 3 seconds increasing the parameter
POSITIONING SYSTEM PARAMETERS ->DECEL RATE will decrease the level distance and
hence time. Similarly reducing the DECEL RATE will increase the level distance and hence time.
9. ADJUSTING THE LEVEL TO ZERO DISTANCE UP/DN (FROM THE CONTROL PANEL) (see Fig 2)
For example the 3 floor lift as Fig1.
a.
Run the lift UP to a floor (preferably a middle floor to avoid terminal / over-travel limits).
b. Make a note of the position it stops at (e.g. 3995).
c.
Run the lift DN to the same floor. Make a note of the position it stops at (e.g. 4007).
d. The results show in the UP direction the lift stopped LOW by 5mm and stopped HIGH in the DN
direction by 7mm. To compensate for this the parameters POSITIONING SYSTEM
PARAMETERS ->LEVEL TO ZERO DIST UP/DN have to be adjusted accordingly. Thus
reducing the UP distance by 5mm and the DOWN distance by 7mm will compensate. Increasing
the distance compensates for overshooting floor level. Reducing the distance compensates for
stopping short of floor level.
e.
Try again to the same floor until the target value of 4000mm ±2mm is achieved. This procedure
only has to be done for one floor, the other floors will be accurate according to these settings.
f.
For a 2 floor lift adjust LEVEL TO ZERO DIST UP/DN for the top /bottom floors respectively.
10. PUT THE LIFT ON PREPARE TO TEST CONTROL (DOORS PARK OPEN).
a.
As 7(a/b/c/d), but Press DN ARROW to display "PARK OPEN"; Press ENTER
