POSITIONING OF THE SHAFT SWITCHES FOR THE DECELERATION
DISTANCE
Legenda:
F - Stop switch before landing (20-30 mm) (the soft stop travel is controlled by the inverter)
S
– Upward travel deceleration distance (shaft switch)
D
– Downward travel deceleration distance (shaft switch)
To achieve a good deceleration the contact at the entrance 9 of the inverter high speed, must be opened at a
distance from the arrival floor, that depends on the speed: the greater the distance, the higher the speed of
the unit.
The opening distance of the entrance high speed from landing be inferred by the following table:

ELECTRICAL GROUP INVERTER
INTRODUCTION
OmarLift uses an inverter which operates in open loop condition, with a special software for hydraulic lifts. It
controls both the upward run and the downward run.
You can achieve the following benefits:
•
No starting current peaks. The maximum starting current never exceeds the nominal current.
•
Power Factor correction.
Cosφ ≥ 0,97.
•
Energy saving.
•
Run comfort optimization.
•
Adjustable inspection speed
•
You can set a maximum limit (optional) for the absorbed power from the mains, in order to reduce
the installed power.
WARNING
Read the manual of the inverter in its entirety before powering up the equipment, following the
procedures step by step.
