Speedlane 900
Edition:
SL900 -OIM - USA
The Speedlane 900 can be operated with an authorization system for example a card reader
system or biometric system. Additionally the Speedlane 900 can be operated with an option
external control panel for remote operation.
3.2 Drive system
Two 3-phase motors with worm gear reduction power the Speedlane 900 doors. The drives are
specifically designed for the Speedlane 900. One motor is installed in the master unit and the other
motor is housed in the slave unit.
The motors are connected to and monitored by a controlling system that consists of a
Microcontroller Board (MCB) and a Frequency Inverter (FI). The output shaft moves the doors
through a parallel gear.
Each motor is equipped with an angle encoder that is connected directly to the motor’s drive shaft.
Using these angle encoders the motor’s speed and position is monitored continuously.
The electric motor has the following advantages:
Silent operation;
For safety reasons the door wing can be stopped by hand;
For security reasons the blocking of the door wing is detected.
3.3 Spring unit on the wide and wide high versions
A pre-loaded spring unit has been fitted to the wide and wide high versions of the Speedlane 900
to compensate for the weight of the glass panel.
When the door wing is close to its fully open or closed position, the motor has to lift the panel
during the final part of the movement.
The design of the spring construction is such that in the middle position no lift force is generated by
the spring. In this situation the spring unit generates no force in the movement directions, thereby
not affecting the light movement.
When the door wings move towards the open or close position the weight of the panels is fully
compensated.
The position and movement of the spring unit has been carefully chosen in such a way that the
torque generated by the spring system closely follows the torque needed to move the door wings.
In this way the increasing torque needed to lift the glass panel is constantly compensated by the
spring unit.
3.4 Control unit
The control system and any other components can be reached by removing the top plate(s) and/or
one or more of the side plates. The master Speedlane 900 unit houses the control system,
comprising of the MCB, the FI and a MBR. The MCB incorporates a microcontroller and the in- and
outputs are located on one side of the MCB. The master Speedlane 900 unit is always placed to
the left when viewed from the non-secured side.
