NFPA 86 Requirements
NFPA 86:2007 provides comprehensive requirements for the safe design,
installation, operation, inspection, testing and maintenance of Class A,B,C and
D ovens, dryers and furnaces. The AADvance system is certified for use with
NFPA 86 compliant systems.
The systems should be integrated in accordance with NFPA 86. In particular
the following shall be applied.
The supplier of the application software for the AADvance controller shall
provide both the end user and the safety authority having jurisdiction with
the documentation needed to verify that all related safety devices and
safety logic are functional before the controller is placed in operation.
In the event of a power failure, the AADvance controller (hardware and
software) shall not prevent the system from reverting to a safe default
condition. A safe condition shall be maintained upon the restoration of
power.
The control system shall have a separate manual emergency switch,
independent of the AADvance controller, which initiates a safe shutdown.
Any changes to hardware or software shall be documented, approved, and
maintained in a file on the site.
System operation shall be tested and verified for compliance with the
NFPA 86 standard and the original design criteria whenever the AADvance
controller is replaced, repaired, or updated.
Whenever application software that contains safety logic or detection logic
is modified, system operation shall be verified for compliance with the
NFPA 86 standard and the original design criteria.
The NFPA 86 certification is only applicable where the system is applied in
accordance with this safety manual and NFPA 86 requirements.
EN 50156
EN 50156-1:2004 applies to the application design and installation of electrical
equipment, control circuits and protective systems for furnaces which are
operated with solid, liquid or gaseous fuels and their ancillary equipment. It
specifies requirements to meet operating conditions for furnaces, to reduce
the hazards of combustion and to protect the heated systems from damage.
The AADvance controller is certified for use an EN 50156 compliant systems.
In particular the AADvance controller controls protective devices for:
monitoring of flames and other safety conditions of the firing
interrupting the flow of the fuel to the furnace for safety reasons
ventilating the body of the furnace and the flue gas ducts
monitoring of safety condition of the heated systems (e.g. water level
limiter in steam boilers)
The EN50156 certification is only applicable where the system is applied in
accordance with this safety manual and EN 50156 requirements.
