Push-Button and Window Housing Flamepaths
The push-buttons and their holes in the Window Housing (on the User Inter-
face, Figure 4-3) are subject to very low rates of wear if they are used under
reasonably clean conditions. However, if the analyzer is exposed to excessive
dust, dirt, or other abrasive conditions, it is possible that the debris may even-
tually enlarge the amepath gap between the push-buttons and their holes in
the Window Housing.
The push-buttons are constructed of aluminum with a blue anodized nish.
The Window Housing is constructed of aluminum with a black anodized nish.
Periodically, examine the push-buttons and the holes in the Window Housing
for any visible signs of wear, such as color loss on the cylindrical portion of the
push-buttons. If the push-buttons show signs of wear or become damaged,
contact your AMETEK Service Representative.
If the push-buttons become stuck, do not attempt to dislodge them
using pliers or any other tools. Do not use any force to dislodge them;
doing so may scratch, bend, or otherwise damage the push-buttons,
causing damage to their amepaths. If this happens, they must be
replaced.
