ALMEGA2 POSITIONING SYSTEM: QUICK SETUP GUIDE
“HYDRAULIC, KP” ISSUE: 3 Date: 05/04/2019
1. PRE-CHECKS (see page 5).
2. SETTING THE OVERRUN DISTANCE
In general the default value of 500mm should suffice to cover the max distance the lift could ever overrun.
However check this distance to ensure the max shaft position values are set correct, before using in normal
operation. They can also be adjusted after the learning run.
a. Set parameters MENU->POSITIONING SYSTEM PARAMETERS->OVERRUN TOP/BOT,
typically-500mm.
3. CLEARING OUT THE FLOOR LEVELS / PREVIOUSLY LEARNED VALUES
This is recommended for each new installation to clear (at the start of installation) any previously learned
floor position values. If this is not carried out the lift may have limited travel because of incorrect
information such as the terminal limits. A common occurrence is the Lift does not go UP on inspection.
This feature can only be selected when on inspection. Once the lift has been commissioned DO NOT USE
THIS FEATURE, IT WILL WIPE ALL FLOOR LEVELS!
a. Select option MENU->POSITIONING SYSTEM INFO->CLR ALL FLOOR LEVELS->YES to
clear floor levels, terminal limit positions, and correction information. *Note only when on
Inspection*
4. SETTING THE TERMINAL LIMITS
a. If parameter “SOFTWARE TERM LIMITS” = NO, Mechanical Terminal Limit Switches
are fitted.
i. Set Terminal Stopping limit switches above/below, top/bot floor level as required.
b. Else if Parameter “SOFTWARE TERM LIMITS” = YES.
Note: Software terminal limits are NOT recommended when using an Over-speed Governor
Encoder because excessive rope slip could cause the terminal limits to move position and
hence the lift could either under-travel, or over-travel onto the Over-travel limits.
i. Set parameter MENU->POSITIONING SYSTEM PARAMETERS->UP TERM LIMIT
DIST as desired (distance above top floor level). Typically set at 25mm.
ii. Set parameter MENU->POSITIONING SYSTEM PARAMETERS->DN TERM LIMIT
DIST as desired (distance below bot floor level). Typically set at 25mm.
iii. If Terminal Limits are required before the LEARN RUN (i.e. manual setting)
1. Take the lift to the terminal floors and record the Absolute Top / Bottom Position
Values, Position Value found by pressing MAIN MENU then LIFT / GROUP
VIEWER and reading P=????
2. Enter the values into system as ENTER FLOOR LEVELS (6). (POSITIONING
SYSTEM PARAMETERS->FLOOR LEVELS).
3. The terminal limits will now be set e.g. 25mm above and below top/bot floor
levels. The lift will stop on these on Inspection Control.
5. LEARNING THE FLOOR LEVELS BY TAKING THE LIFT TO EACH FLOOR ON INSPECTION.
a. If PANEL TEST CONTROL is fitted
i. Switch to Inspection.
ii. Take the lift to the bottom, and 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.
b. Else if PANEL TEST CONTROL is NOT fitted
i. On the main terminal rail (lift shaft/car side) remove the wire in terminal TS and mark it,
then wire in the same terminal as TS1. This will switch to Inspection.
