Digital Equipment Pro-face FP2500-T12 Installation Manual

• Prior to connecting the FP2500-T12/FP2600-T12 (hereafter referred to as the "FP"or
FP unit) unit's power cord terminals to the Terminal Block, be sure to check that the
FP unit's power supply is completely turned OFF, via a breaker, or similar unit.
• Whenever changing the backlight be sure to unplug the FP unit's power cord and
wear protective gloves to prevent electric shocks and burns.
• Do not open or remodel the FP unit. Doing so may lead to a fire or electric shock.
• Do not use voltage levels that exceed the FP unit's specified voltage range. Doing so
may cause a fire or an electric shock.
• Do not use the FP in an environment where flammable gases are present, since
operating the FP may cause an explosion.
• Do not use the FP as a warning device for critical alarms that can cause serious
operator injury, machine damage or production stoppage. Critical alarm indicators
and their control/activator units must be designed using stand-alone hardware and/
or mechanical interlocks.
• Do not use FP unit touch panel switches in human-safety-related or important disas-
ter prevention situations. For safety-related switches, such as an emergency stop
switch, be sure to use a separately installed mechanical switch.
• After the FP unit's backlight burns out, unlike "Standby Mode", the unit's touch panel
is still active. If the operator fails to notice that the backlight is burned out and touches
the panel, a potentially dangerous machine operation error can occur. Therefore,
do not use FP unit touch-screen switches for the control of equipment safety mecha-
nisms, such as Emergency Stop switches, etc. that protect humans from injury and
equipment from damage.
If your FP unit's backlight suddenly turns OFF, use the following steps to determine
if the backlight is actually burned out.
1) If your currently running FP application is not set to turn the backlight OFF, and the
screen has gone blank, your backlight is burned out.
2) If your current FP application is set to turn the backlight OFF, if touching a corner of the
screen does not cause the display to reappear, your backlight is burned out.
• To prevent operator injury or machine damage, be sure to design your machine op-
eration system so that the machine will not malfunction due to a communication fault
between the FP unit and its host controller.
• Do not use the FP with aircraft control devices, aerospace equipment, central trunk
data transmission (communication) devices, nuclear power control devices, or medi-
cal life support equipment, due to these devices' inherent requirements of extremely
high levels of safety and reliability.
• When using the FP with transportation vehicles (trains, cars and ships), disaster and
crime prevention devices, various types of safety equipment, non-life support related
medical devices and others, be sure to use redundant and/or failsafe system designs
to ensure the appropriate degree of system reliability and safety.
