The keypad keys (é and ê) can be used to change the value within the brackets as described below:
FLOOR: This is the Lift Floor Position, i.e. the number of recorded floor positions.
ADJUST: This is the adjustment that can be made to the floor LEVEL position. The adjustment
direction will appear when the value is altered. i.e. 100mm UP, or 5mm DN etc.
LEVEL: This is the absolute floor position of the floor LEVEL. Adjusting this allows the user
to enter numbers in absolute format, thus major floor adjustments are entered here.
11. TESTING THE SLOWING LIMITS
a. Run the lift to a Terminal floor on HIGH speed. Press and hold both MODE + MENU on the
Almega keypad. This will inhibit the position stepping and force the lift to slow on the slowing
limit. If the lift stops out of the "WITHIN FLEV DISTANCE " the lift will not open its doors. If
"OUT OF LEVEL RECOVERY" is set to YES, the lift will automatically re-level back to floor
level and then open its doors. The procedure should also be repeated for a single floor run.
12. TESTING THE TERMINAL LIMITS
a. Run the lift to a Terminal floor on any normal run speed. Press and hold both MODE + ESC on
the Almega keypad. This will inhibit the stopping and force the lift to stop on the terminal limit. If
the lift stops out of the "WITHIN FLEV DISTANCE " the lift will not open its doors. If "OUT OF
LEVEL RECOVERY" is set to YES, the lift will automatically re-level back to floor level and then
open its doors. This procedure may also be used to test OUT OF LEVEL RECOVERY at any floor.
13. CANopen INFORMATION
a. The Positioning system is designed for use with Position Devices incorporating the CANopen
industry standard communication protocol. Therefore information can be transferred from the
device and viewed by selecting option MENU->POSITION SYSTEM SETUP-> CANOPEN
INFO. In particular the error information can be viewed as below:
i. Schmersal USP: Screen 1 = USP wire Errors / Warnings
ii. Hengstler AC58: Screen 1 = Contains Alarm / Warning messages.
14. FURTHER INFORMATION FOR USE WITH AN OVERSPEED GOVERNOR ENCODER (If fitted)
a. Resetting the Absolute Position:
It may be necessary to reset the absolute position of the lift for the following reasons:
i. Excessive Correction: See below
ii. Clear Correction Levels: With the lift physically at the bot flr level, select to clear.
Select option MENU->POSITION SYSTEM SETUP-> RSET ENCODER POSITION ->YES to
reset the absolute position of the encoder to the position of the bottom floor level.
b. Correction Point Moved: It is vital that correction points do not move once set after a learn run.
IT IS STRONGLY RECOMMENDED THAT CORRECTION SENSOR / POINTS ARE FIXED
SO THAT THEY DO NOT MOVE. If they do move they will affect floor levels to the amount
moved (i.e. 30mm UP if moved 30mm UP etc). Rectify by (v) “Corr Fault Info” (as below)
c. Correction Point Missing: If a correction point is not found the event “CORRECT POINT
MISSING" is generated in the event logger, and the position error will NOT be corrected! This can
be caused by (i)-(v) as “Corr Fault Info” (as below).
d. Correction Point exceeded: If the level of correction is exceeded, the event “POS DEV CORR
EXCEEDED" is generated in the event logger, and the position error will NOT be corrected! The
level in the software is typically set to 50mm. This can be caused by (iv) or (v) as “Corr Fault Info”
(as below).
e. Correction Fault Info: When the lift has arrived at its destination it looks for a correction point
before stopping. If missing / exceeded the lift will still operate as normal but floor levels will
slowly drift over time (due to rope slip) until the app action [as below] is taken.
i. Corr Point missing [re fit corr point]
ii. Corr Sensor Failed [new sensor]
iii. Floor Level adjusted > half corr vane length (i.e. >150mm for a 300mm vane) [move corr
point central then new learn run].
iv. Excessive OSG Rope Slip i.e. the OSG trips and the rope slips [move rope back, or reset
abs posn, or new learn run]
v. Corr Sensor Moved [Move back, or new learn run]
f. Correction information: Select option MENU->POSITION SYSTEM SETUP-> CORRECTION
INFO to view the current correction information. From this menu correction point parameters and
current correction levels can be viewed for each floor. A test would be to run the lift to each floor
and the current level should be similar for each floor. If one is vastly different to all the rest then
typically the correction point for that floor has moved.
g. Position Device Power Output: Typically the position encoder will be powered through a relay
output from the micro processor. This is to reset the encoder under communications failure by re-
cycling the power. If a communications lost condition is detected this output will de-energise every
10 seconds for 2 seconds to re-cycle the power.
