Gp Series Of Panels - Pro-face GP4104G1D Hardware Manual

GP Series of Panels

Critical systems, alarms and handling Requirements
Critical alarm indicators and system functions require independent and redundant
protection hardware and/or mechanical interlocks.
When you cycle power, wait at least 10 seconds before restoring the power to the
GP unit after it has been turned off. Switching the power OFF and ON quickly can
damage the GP unit.
In the event the screen cannot be properly read, for example, if the backlight is not
functioning, it may be difficult or impossible to identify a function. Functions that may
present a hazard if not immediately executed, such as a fuel shut-off, must be
provided independently of the GP unit. The machine's control system design must
take into account the possibility of the backlight no longer functioning and the
operator being unable to control the machine or making mistakes in the control of
the machine.
For additional information, refer to NEMA ICS 1.1 (latest edition), "Safety Guidelines
for the Application, Installation, and Maintenance of Solid State Control" and to
NEMA ICS 7.1 (latest edition), "Safety Standards for Construction and Guide for
Selection, Installation and Operation of Adjustable-Speed Drive Systems" or their
equivalent governing your particular location.
LOSS OF CONTROL
The designer of any control scheme must consider the potential failure modes
of control paths and, for certain critical control functions, provide a means to
achieve a safe state during and after a path failure. Examples of critical control
functions are emergency stop and overtravel stop, power outage and restart.
Separate or redundant control paths must be provided for critical control
functions.
System control paths may include communication links. Consideration must be
given to the implications of unanticipated transmission delays or failures of the
link.
Observe all accident prevention regulations and local safety guidelines.
Each implementation of this equipment must be individually and thoroughly
tested for proper operation before being placed into service.
The machine control system design must take into account the possibility of the
backlight no longer functioning and the operator being unable to control the
machine, or making errors in the control of the machine.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
UNINTENDED EQUIPMENT OPERATION
Do not use this equipment as the only means of control for critical system
functions such as motor start/stop or power control.
Do not use this equipment as the only notification device for critical alarms, such
as device overheating or overcurrent.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
