Lower Electronics Module
The lower control module consists of an AC drive motor controller, an AC
lift motor controller and a +8.5V DC power supply to power the console.
The electronic circuits in the console operate on +5V DC, however the
lower control module sends +8.5V DC due to the optional external
equipment such as Fitlinxx, that may be connected to the CSAFE
(Communication Standard for All Fitness Equipment) port. Sending a higher
voltage (+8.5V) and regulating the voltage down to +5V DC, ensures that
we can supply enough power to both the console and the optional external
equipment.
It is important to note that the lower control module is a different part
number for a 120V unit than for a 240V unit.
