Important Highlighted Information; Control Reliability - Honeywell SYA14 Series Manual

1.3 Important Highlighted Information

Important danger, warning, caution and notices are highlighted throughout the manual as follows:
A DANGER symbol indicates an imminently hazardous situation which, if not avoided, will result in death or
serious injury.
A WARNING symbol indicates a potentially hazardous situation which, if not avoided, could result in death or
serious injury.
A CAUTION symbol indicates a potentially hazardous situation which, if not avoided, may result in property
damage.
A NOTICE symbol indicates important information that must be remembered and aids in job performance.

1.4 Control Reliability

"Control Reliability" means that, "the device, system or interface shall be designed, constructed and installed
such that a single component failure within the device, interface or system shall not prevent normal stopping
action from taking place but shall prevent a successive machine cycle." (ANSI B11.19-1990, 5.5)
OSHA 29 CFR 1910.217 states that, "the control system shall be constructed so that a failure within the system
does not prevent the normal stopping action from being applied to the press when required, but does prevent
initiation of a successive stroke until the failure is corrected. The failure shall be detectable by a simple test, or
indicated by the control system."
Honeywell has developed a self-checking technique that combines reliability with safety. The FF-SE Series
safety laser scanner functions with dual channel redundancy and positive self-check monitoring. This means that
a faulty component in our product will make the safety laser scanner fail in a safe mode.
This design meets the highest safety requirements described in the IEC/EN 61496-1 and pr EN 61496-3 norms
for laser scanners. The FF-SE is designed and manufactured in such a way that a single breakdown does not
lead to the loss of the safety function when a dangerous situation arises. The safety function is maintained on
a permanent basis.
