landing control station
Note:
When running the 1.7 m/sec. high
speed hoist to the next upper or lower
landing - ALWAYS depress the Stop
Next Landing button immediately
before the hoist starts, to achieve
normal operation speed.
Semi-automatic control system: (Stop Next Landing)
This is the least complex used control system available in the
ALC controller and operates without any landing cams. The
position of the lift is determined by counting impulses generated
by the pulse encoder attached to the gear box.
The lift can be operated push-buttons or with joystick from
inside the car and if chosen, also from the landings by using Up,
Down and Stop Next Landing push-buttons.
With the joystick, or by pressing a button for Up or Down, the
car starts travelling in the chosen direction. When the car
approaches the desired landing, the button Stop Next Landing
is pressed. The car will then stop automatically at the landing.
Calls / destinations from a 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 lift can be operated from inside the car and if
chosen, also from the landings. Each landing is provided with
two call buttons, one for each travel direction.
There are two means of operating the lift from inside the car:
By destination push-buttons – one for each landing (perm. lifts).
By keypad (construction hoists).
This system receives all destination orders from inside the car, as
well as calls from the landings. The information is memo-rized
and processed within the system.
