8 .4 Removing the MTL GECMA WS Display module
The display module is now clear of all other fittings and can be prepared for removal.
IMPORTANT
If the display is still upright in the enclosure then an additional person should be
positioned at the front of the enclosure to support the display during its removal.
1. Loosen and remove all of the securing nuts located around the outer edges of the
display module, and lift away any reinforcing metal strips that may be located on
the studs.
2. Gently ease the display (with any sealing gasket fitted) away from the face of the
enclosure until the studs are clear of the enclosure, and place the display in a
safe position.
8 .5 Re-Installing an MTL GECMA WS Display module
Remove all packaging material from the replacement display and check the display for
any damage, e.g. any warping or distortion of the edges of the display or any indications
of rough handling.
WARNING!
Do not attempt to install a display module that shows any signs of damage
or mishandling as it could compromise the Ex certification of the unit.
IMPORTANT
It is recommended that an additional person assists with the fitting of the display module
to the enclosure as it is difficult to support the display and have full access to the fixings
required at the rear.
1. Ensure that the face of the enclosure and the mating surface around the edge of
the display module is free of any contamination or loose particles that could prevent the
seating of the module to the enclosure face.
2. Refit any new or existing gaskets (new gaskets supplied with new display) over the
studs before bringing the display module to the enclosure and inserting the studs
around the edge of the display through the holes in the enclosure.
3. Fit any reinforcing metal strips, previously removed, over the fixing studs and refit the
securing nuts. Initially tighten the nuts only to “finger” tightness until all of them have
been fitted. View the display from the front to ensure that there is no distortion at the
display edges and then tighten all the nuts along each edge in turn with a wrench to a
recommended torque of 2Nm. On completion, check the front face once again to
check for good seating of display and enclosure.
