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-SRM Series muting module functions with dual channel redundancy and positive
self-check monitoring. This means that a faulty component in our product will make the
muting module fail in a safe mode.
This design meets the highest safety requirements (category 4) described in the EN 954-1
norm. The French Institut National de la Recherche et de la Sécurité has delivered an EC
type examination certificate for an equipment made of a type 4 electrosensitive protective
equipment and the FF-SRM muting module. The whole set complies with the requirements
of the IEC/EN 61496-1 and IEC / pr EN 61496-2 norms.
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 safety function is maintained on a permanent basis.
