sively by an authorized Robur Technical Assistance Centre (TAC) and according to the
instructions supplied by the manufacturer.
To carry out entire procedure correctly, follow the instructions in Paragraph 6.1 PROCE-
DURE FOR INITIAL ACTIVATION → 59.

Operation and maintenance of the appliance
To ensure the correct operation of the appliance and to avoid failures, control of the
switching on and o of the appliance must be done in line with the requirements of the
various types of installation.
If the appliance is connected to the DDC (see Figure 5.3 Direct Digital Control •
(DDC) → 41), the appliance may be switched on and o exclusively by the DDC
itself.
If the appliance is NOT connected to a Direct Digital Control (DDC) the appliance •
may be switched on and o exclusively by a switch on the consent circuit.
The appliance must never normally be switched on and o by shutting o the power
supply upstream of the Controle Device (CCP, DDC or consent switch) before having used
the latter rst and waited for the shutdown cycle to end (approximately 7 minutes). The
shutdown cycle terminates when the hydraulic pump switches o (no parts in motion).
Shutting o the power supply while the appliance is running can irreparably damage its
internal components!
If the appliance fails to operate correctly, with the consequent indication of the Machine
code, follow the instructions of Paragraph 8.1 MACHINE OPERATING CODES → 69.
In the event of failure of the appliance and/or breakage of any of its parts, refrain from
any attempt to repair and/or restore operation of the appliance through direct action.
