Alimak Lift Control ALC
Two different control systems
In the main software there are two different control systems
available:
Semi-Automatic (or Stop Next Landing) and Collective.
The ALC system automatically selects the control system.
Semi-Automatic control system
This is the most common control system
available in the ALC controller and operates
without any landing cams. The position of the
hoist is determined by counting impulses
generated by the pulse encoder attached to
the car.
The hoist can be operated from inside the
car and if chosen, also from the landings by
using Up, Down and Stop Next Landing
push-buttons.
By pressing a button for Up or Down, the
hoist starts travelling in the chosen direc-
tion. When the hoist approaches the desired
landing, the button Stop Next Landing is
pressed. The car will then stop automatically
at the landing.
Calls/destinations from the landing box unit with
Up, Down and Stop Next Landing push-buttons
operate on 230 VAC control wires between the car
and the landings via the base-panel.
A destination order from the car has three seconds priority
over landing calls.
Collective control system
This is the most advanced control system available in the ALC
controller. The hoist can be operated from inside the car by
destination push-buttons and if chosen, also from the landings.
Each landing is provided with two call buttons, one for each
direction of travel.
This system receives all destination orders from inside the car,
as well as calls from the landings. The information is memorized
and processed within the system. During the travel the hoist will
automatically stop at all floors which have been addressed.
