3.18 Electronic controller
The machine is fitted with 2 electronic controllers
located at the rear of the chassis, between the driving
wheels.
The master controller is located on the right side of
the chassis and the slave controller on the left side.
The master controller controls the right drive motor.
The slave controller controls the left motor.
Both controllers are identical and fitted with the same
program. The inputs wiring helps to identify the master
controller from the slave controller.
NOTE
Use of this machine in an environment with
electromagnetic interferences may result in
fluctuations in speed of certain movements
(slowing down) and the actuation of acoustic
and light alarms. All functions and safety
devices of the machine remain operational.
The controllers are fitted with 4 Molex Minifit connectors
