ROUTINE CHECKS
In order to ensure correct operation of the controller, the cabin doors must be kept closed.
Every six months you are advised to inspect and if necessary, clean the dissipater of the Servo Amplifiers
Unit rack SAU2, to be found in the rear controller compartment. Access to the compartment is gained by
backing off the screws fastening the controller rear door and opening it.
BUFFER BATTERY REPLACEMENT/STORAGE
Batteries that are not in use should be stored in an environment with a temperature below
25° C. They should be checked periodically (every 3 months) measuring the no-load voltage
that is not to drop below 3.86 V.
The CONTROL UNIT buffer battery must be replaced every three years of operation proceeding as follows:
·
Open the left cabin door
· Move the back-up battery switch above the Control Unit to OFF
·
Slacken the knobs fastening the back-up battery support to the Control Unit, remove and disconnect the
connectors (A) of the buffer battery
·
Connect the new back-up battery, close the support again and turn the switch ON.

When replacing the battery avoid contacts between the metal parts of the controller and
