7. Maintenance
This chapter gives instructions on how to carry out routine and special maintenance.
Routine maintenance
refers to those operations which must be carried out
periodically. As they do not require specific skills, they can be carried out by the
users (operators, etc.).
Special maintenance
refers to unforeseeable operations due to mechanic or electric
failures. They require specific technical skills, so they should be exclusively carried
out by qualified personnel (maintenance personnel etc.).
7.1 Routine maintenance
Routine maintenance consists in cleaning the instrument.
Clean the instrument using a damp cloth and a mild detergent to avoid erasing the
serigraphs on the panel.
!
Warning
Do not use pressurised water jets.
Do not use abrasive products, solvents or alcohol.
Do not press on the keyboard with pointed or hard objects as they
could damage the polyester film, particularly compromising the
impermeability of the keyboard.
7.1.1 Protection fuses
The XP805 computer is fitted with SELF-RESETTING fuses for short-circuit
protection on the sensors or on the row closing devices; in the event of a fault, these
fuses intervene by disconnecting the power supply to the sensors or to the closing
devices: in this case, disconnect the main wiring for a few minutes, eliminate the
cause of the fault and connect the wiring to the monitor again.
7.1.2 How to protect the main connector
During prolonged periods of inactivity we recommend disconnecting the main signal
connector (see Figure 3
– Ref. J on page 9) and isolate it from the environment with
Nylon protection.
7.2 Extraordinary maintenance
!
Warning
Special maintenance must only be performed by authorised personnel.
