3.12. ALE MET DRIVER OPERATION (LOW KIT)

3.12.1. ALE MET
This is the electronic device that receives the line voltage and, through a PFC module, it rectifies the
voltage to the 400Vdc used to generate the 3 phase voltage for the belt motor. It generates the DC
voltages to power up all the other devices of the machine.
It's the device that acts as an interconnection hub for the main components of the lower assembly,
and serves as the point of connection with the display. In fact:
it supplies the +12Vdc voltages to the display;
it supplies the tread belt motor with a variable-frequency sinusoidal voltage: varying the
frequency varies the speed of rotation of the motor, and consequently the speed of the tread
belt;
it exchanges, over the RS-485 serial link to the Display Board, the commands for controlling
the tread belt and elevation motors;
it exchanges, over the RS-485 serial link to the Display Board, the commands for viewing
and configuring the inverter parameters;
it exchanges, over the RS-485 serial link to the Display Board the commands for viewing the
errors logged by the inverter.
From the outside the following indicator LEDs are visible:

DRIVER
H6 GREEN +5Vdc (if ON proper functioning)
H3 GREEN +12Vdc (if ON proper functioning)
GREEN +24Vdc (if ON proper functioning)
H4
H5 BLUE 400Vdc (if ON proper functioning)
Colour
If ON indicates that the AT UL driver has detected an error
(EdC) when it was moving the elevation motor. This LED
RED
stay ON for about 1 second and then goes OFF.
if ON indicates that the motor has received the supply
GREEN
voltage for movement in the upward direction
if ON indicates that the motor has received the supply
RED
voltage for movement in the downward direction
functioning of elevation motor encoder: if blinking, indicates
GREEN
that the board is receiving the pulses from the encoder
status of Limit switch contact: if ON indicates that the
GREEN
microswitch is pressed
