Critical Systems, Detected Alarms, and Handling Requirements
Critical detected alarm indicators and system functions require independent and redundant protection hardware and/or mechanical interlocks.
If the unit for any reason becomes inoperative (for example, an inoperative back-light) it may be difficult or impossible to identify operation. Operations that may present a hazard if not immediately executed, such as emergency stop, must be provided independently of the unit. The design of the control system must take into account an inoperative unit (back-light) and the operator is maybe unable to control the machine or respond to detected errors with the unit.
When the power is cycled, wait at least 10 seconds before restoring the power to the HMI unit. Switching the power OFF and ON can quickly damage the unit.
NOTE: The HMISCU should always have the display module and controller module connected for an application to function properly.
If the rear module is powered without it being directly connected (or connected with a separation cable) to the display module, the PLC Logic goes into the STOP mode with I/Os in a fall-back mode.

EXPLOSION HAZARD |
|
oDo not connect or disconnect while circuit is live. oPotential electrostatic charging hazard: wipe the front panel of the terminal with a damp cloth before turning ON. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
|
|
|
LOSS OF CONTROL |
|
oConsider the potential failure modes of control paths in the machine control system design, such as: oThe possibility of backlight failure, oUnanticipated link transmission delays or failures, oThe operator being unable to control the machine, oThe operator making errors in the control of the machine. oProvide a means to achieve a safe state during and after a path failure for critical control functions such as emergency stop and overtravel stop. oProvide separate or redundant control paths for critical control functions. oObserve all accident prevention regulations and local safety guidelines.1 oTest individually and thoroughly each implementation of the equipment for correct operation before service. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
1 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.

UNINTENDED EQUIPMENT OPERATION |
|
oDo not use this equipment as the only means of control for critical system functions such as motor start/stop or power disconnect. oDo 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. |
The following characteristics are specific to the LCD and are considered normal behavior:
oLCD screen may show unevenness in the brightness of certain images or may appear different when seen from outside the specified viewing angle. Extended shadows, or cross-talk, may also appear on the sides of screen images.
oLCD screen pixels may contain black and white-colored spots and color display may seem to have changed over time.
oWhen the same image is displayed on the screen for a long period, an after-image may appear when the image is changed. If this happens, turn off the unit, wait 10 seconds, and then restart it.
NOTE: Do not display the same image for a long time. Change the screen image periodically.

|
SERIOUS EYE AND SKIN INJURY |
|
The liquid present in the LCD contains an irritant: oAvoid direct skin contact with the liquid. oWear gloves when you handle a broken or leaking unit. oDo not use sharp objects or tools in the vicinity of the LCD touch panel. oHandle the HMI carefully to prevent puncture, bursting, or cracking of the HMI material. |
|
Failure to follow these instructions can result in injury or equipment damage. |
If the HMI is damaged and any liquid comes in contact with your skin, immediately rinse the area with running water for at least 15 minutes.
If the liquid gets in your eyes, immediately rinse your eyes with running water for at least 15 minutes and consult a doctor.
|
|
|
UNINTENDED EQUIPMENT OPERATION |
|
oOperate the touch panel with only one finger. oDo not activate two or more points of the touch panel simultaneously. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
Use only one finger to select an object on the touch panel.
If the touch panel receives pressure at two or more points at the same time, an unintended object could be selected.
