Main contactor control board (MCCB)

The main contactor control board, located in the drive box, is used for the control of a single
or 3 phase inverter up to 2,2kW. With the 2 main contactors K50 and K51 both the inverter,
as well as the motor brake are controlled. Details of the function are shown in the wiring
diagram.

Platform control

The illustration below shows the main communications components for the platform control:

Via the tensions rope the platform is supplied with voltage and information. For the drive
commands the user can use a handset or a joystick connected to the platform control. The
status of the platform can be seen on the LCD display. A 7.segment display shows the
current status of the unit.

The platform control has also 2 outputs to steer actuators. 1 is generally used to steer the
main actuator responsible for opening and closing of the platform and barriers. A second
one can be used to control a lateral access ramp.
