OPERATOR INTERFACE
DESCRIPTION
The Quantum™ SIP Operator Interface consists of two
components: A color 15” (diagonally measured) graphic
display and a resistive touchscreen and a membrane touch
overlay. The display is used to view information coming
from the Q5 controller, while the touchscreen allows the
operator to navigate the menus.
DISPLAY ASSEMBLY
The Display assembly consists of a 1024 x 768 resolution
LCD screen (which includes LED backlight sticks, and a
wiring harness). Refer to the Parts List at the end of this
manual for speci
fi
c replacement part numbers.
NOTE:
Before replacing a display unit, ensure that the
symptom is not actually being caused by a bad back-
light LED stick, harness or jumper setting.
