Maintenance
XTA
The XTA is low maintenance and as such requires only minimal periodic inspection.
The integral bearing is dry running, requiring no lubrication.
Periodically:
•
Check that the thrust rod can move freely over the entire stroke.
•
Clean any accumulated debris from the thrust rod surface (ferrous material, in particular, can be attracted to the
thrust rod surface).
•
Check all fixings are tight and secure.
XTB
The XTB is low maintenance and as such requires only minimal periodic inspection.
Where an external linear bearing is used, please consult the bearing manufacturer for recommendations on lubrication
types and lubrication intervals.
Periodically:
•
Check that the forcer can move freely over the entire stroke.
•
Clean any accumulated debris from the thrust rod surface (ferrous material, in particular, can be attracted to the
thrust rod surface).
•
Check all fixings are tight and secure.
•
Check all flexing cables for signs of wear or damage.
WARNING
ISOLATE AND DISCONNECT ALL SOURCES OF ELECTRICAL SUPPLY BEFORE WORKING
ON THE EQUIPMENT.
CABLE REPLACEMENT
If a cable needs to be replaced it will be necessary to gain access to the termination box inside the pod, see Figure 3.1.
Removal
•
Unscrew the four M3 pod cover fixings.
Note that the fixings are of different lengths.
Make a record from where each fixing is removed so they can be correctly replaced later.
•
Remove the pod cover from the termination box.
•
Unscrew the pressure nut from the cable gland.
•
Disconnect the power cable from the screw terminal connector, TB1 and the earth terminal and/or unplug the
sensor cable from the PCB at connector PL1.
