A.8 Maintenance
WARNING
Before performing service or maintenance operations (unless otherwise indicated), ensure
that power is turned off to the unit to avoid injury and/or damage to equipment.
WARNING
Installation, conguration, commissioning, maintenance, and repairs must be performed
by approved and qualied personnel only.
A.8.1 Periodic Inspection
• Inspect the general condition of the XTE3000/3000AD at regular intervals. The
recommended frequency of inspection is once every two years but this frequency
could change depending on the installation and working conditions. Any crack on
the surface, broken windows, or loose bolts must be reported for repair.
• Keep the external surfaces of the unit clean: if the unit is installed in a dusty
environment, the specication stated in IEC/EN 60079-14 is to be followed
(ensuring in particular that the dust layer does not exceed 5 mm.)
• If the actuator is covered by an intumescent coating ("Kmass"), an electrostatic
charge risk is present; only anti-static cloth may be used when cleaning is required.
When performing maintenance, avoid rubbing actions against the actuator (or any
other friction-inducing action) that could electrostatically charge the unit.
• Check the condition of cable connections and mounting bolts; any loose
connection must be tightened.
A.8.2 Disassembly and Re-assembly
CAUTION
Using a fastener other than the approved type may result in damage to the actuator or
valve. Refer to Table 7.
CAUTION
Failure to use proper torque values can result in damage to the actuator and/or valve.
