EL552.256-Q2 Operations Manual (OM410-00) 3
Mounting EL Displays
Properly mounted, EL displays can withstand high shock loads as well as severe
vibration found in demanding applications. However the glass panel used in an EL
display will break if subjected to bending stresses, high impact, or excessive loads.
CAUTION: To prevent injury in the event of glass breakage, the use of
an impact resistant shield or a protective overlay should be used on the
viewer side of the display.
Stresses are often introduced when a display is mounted into a product. Ideally,
the mounting tabs of the display should be the only point of contact with the
system. Use a spacer or boss for support; failure to do so will bend the display and
cause the glass to break. The instrument enclosure or frame should not flex
or distort in such a way that during use the bending loads might be transferred to
the display. Mounting surfaces should be flat to within ±0.6 mm (±0.025"). Use
all the mounting holes provided. Failure to do so will impair the shock and
vibration resistance of the final installation.
The EL552.256-Q2 is a tab-mounted display. Use standoffs of appropriate length
to assure that screws through the mounting tabs do not introduce bending stresses
to the display. Do not deflect the ECB out of its normal plane. The EL552.256-Q2
mounting tabs were designed for a 3 mm screw. The EL552.256-Q2 NE display
does not have mounting tabs. Contact Planar Applications Engineering for
information on mounting the EL552.256-Q2 NE display.
WARNING: These products generate voltages capable of causing
personal injury (high voltage pulses up to 230 VAC ). Do not touch the
display electronics during operation.
Cable Length
A maximum cable length of 0.6 m (24 in.) is recommended. Longer cables may
cause data transfer problems between the data transmitted and the display input
connector. Excessive cable lengths can pick up unwanted EMI. There are third
party products which allow this maximum cable length to be exceeded. Contact
Planar Application Engineering for more information.
Cleaning
As with any glass or coated surface, care should be taken to minimize scratching.
Clean the display glass with mild, water-based detergents only. Apply the cleaner
sparingly to a soft cloth, then wipe the display. Disposable cleaning cloths are
recommended to minimize the risk of inadvertently scratching the display with
particles embedded in a re-used cloth.
