Important Highlighted Information; Control Reliability - Honeywell SYA14 Series Manual

Important Information

Important Highlighted Information

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

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-SM Series mat functions with dual channel redundancy and positive self-check monitoring.
This means that a faulty component in our product will make the safety mat fail in a safe
mode.
This design meets the highest safety requirements (sensor : category 3 / control unit :
category 4) described in the EN1760-1 and EN 954-1 European norms. Category 3 devices
are 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. Category 4 devices are
designed and manufactured in such a way that a single breakdown or an accumulation of
failures does not lead to the loss of the safety function when a dangerous situation arises.
The combination of both devices ensures the safety function is maintained on a
permanent basis.
