How to manage a control system
Through the communication features,
it is possible to transmit all the relevant

programmable and can show
instantaneous values, display the
alarm situations with customized
messages and start-stop the motor.
How to see the historical trend of variables

dataloggers to store the trend over
time of:
• Up to 20 variables at the choice of
the user (like voltages, temperatures,
TCU, …).
• Fast track up to 20 variables at
every start (again at the choice of
the user).
• Record events like starts and stops,
system power ON/OFF, change of
status of physical as well as network
inputs and outputs, alarm trips, …
• Alarm display to the supervision
system or using properly located
