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-SYA Series safety light curtain functions with dual channel redundancy and
positive self-check monitoring. This means that a faulty component in our product will
make the safety light curtain fail in a safe mode.
This design meets the highest safety requirements (type 4) described in the IEC/EN
61496-1 and IEC/pr EN 61496-2 norms. Type 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 safety function is
maintained on a permanent basis.
