Quality System 1
Quality System
Issue Date: 5 January, 2000
Revised Date: 10 May 2006
Red Lion Control's Quality System is designed, documented, implemented and maintained around the
International Standard of ISO-9001 and the company Quality Policy. This system lays down the foundation for more
effective quality assurance and continuous improvement, company-wide, in order to provide top quality products and
services to our customers, worldwide.
It is the policy of Red Lion Controls to produce products and provide services which meet or exceed all of our
customers quality, performance, and reliability expectations.
CE Marked Products
Almost all Red Lion products have earned the right through design and compliance testing to carry the CE
mark. The CE mark encompasses the Electro Magnetic Compatibility (EMC) Directive 89/336/EEC and the Low
Voltage Directive (LVD) 72/23/EEC, which have been published in the harmonized standards of the Official Journal
of the European Communities.
The Low Voltage Directive (LVD) states that a product must meet an IEC safety standard that is relevant to
the product. RLC currently designs to IEC 1010 (Safety requirements for electrical equipment for measurement,
control and laboratory use).
Application of the CE mark indicates that the RLC product meets the required EMC and Safety standards
when installed properly.
EMC Directive
The EMC Directive simply implies that a product must not interfere with radio communications or other
electronic devices. Also it requires that products must have an inherent level of immunity to outside sources of
electromagnetic disturbances.
To meet the EMC Directive, product must conform to a test standard. If no product specific standard exists
then the manufacturer must choose a generic standard. It should be noted that products such as medical devices
and machinery equipment do have product specific standards to meet. RLC products meet the directive by testing to
standard EN 61326 electrical equipment for measurement control and laboratory use.

Safety Agency Marks

To ensure compliance with the relevant statutory safety requirements, many RLC products are CE marked
and Recognized to US and Canadian requirements under the Component Recognition Program of Underwriters
Laboratories Inc.
The identification of the safety agency standard that RLCs product has been tested and evaluated to, may
be necessary in order for the installation application to be properly UL Recognized or UL Listed. RLC products are
not stand alone units, therefore they receive the agency UL Recognition Marks, not the UL Listed Marks. The
complete stand alone system unit, such as an electrical control panel will receive an agency UL Listing Mark based
upon the UL Recognition Marks of each individual component used within that complete electrical control panel
system.
The product literatures specification section list the certifications and compliances that the product meets.
Also listed is the file number, report numbers, standards numbers and descriptions for use by the customer in
determining compliance in their end product application.
For compliance of CE Marking, many RLC products are submitted to UL for test and evaluation to
harmonized standards UL 3101-1, Electrical Equipment for Laboratory Use; Part 1: General Requirements or UL
3111-1, Electrical Measuring and Test Equipment; Part 1: General Requirements for obtaining a CB Test Certificate
and CB Test Report.
UL participates in the CB Scheme. This is an international system for the mutual recognition of test results
among National Certification Bodies (NCB). The international Scheme operates under the auspices of the IEC
(Council of the International Electrotechnical Commission) based in Geneva. The purpose of the CB Scheme is to
provide a system for the acceptance of test results, based on internationally harmonized standards, for the purpose
of obtaining product certification at a national level. 36 National Certification Bodies (NCBs) have been accredited
and accepted within the Scheme, including all major testing laboratories in Europe, Pacific Rim countries, Canada
and the USA. The Scheme covers electrical and electronic products tested to the relevant IEC Standards, and
corresponding national deviations, where required. As an accredited NCB, UL, etc. will assess the product and issue
a CB Test Certificate and CB Test Report for the tested product. The manufacturer then presents this Certificate and
Test Report to the NCB in the country where certification is desired. Although an application to the local NCB is
necessary, the test report issued by UL etc. should eliminate the need for any further testing. 3
EMI Installation Guidelines

Although Red Lion Controls Products are designed with a high degree of immunity to Electromagnetic
Interference (EMI), proper installation and wiring methods must be followed to ensure compatibility in each
application. The type of the electrical noise, source or coupling method into a unit may be different for various
installations. A unit becomes more immune to EMI with fewer I/O connections. Cable length, routing, and shield
termination are very important and can mean the difference between a successful or troublesome installation. Listed
are some EMI guidelines for a successful installation in an industrial environment.

1. To reduce the chance of noise spikes entering the unit via the power lines, connections should be made to a clean
source. Connecting to circuits that also power loads such as contactors, relays, motors, solenoids etc. should be
avoided.
2. A unit should be mounted in a metal enclosure, which is properly connected to protective earth.
2.a. Units that have a metal bezel should have the bezel connected to protective earth. This can be done by making
sure the metal bezel makes proper contact to the panel cutout or connecting the bezel screw with a spade
terminal and wire to protective earth.
3. Use shielded (screened) cables for all Signal and Control inputs. The shield (screen) pigtail connection should be
made as short as possible. The connection point for the shield depends somewhat upon the application. Listed
below are the recommended methods of connecting the shield, in order of their effectiveness.
3.a. Connect the shield to earth ground (protective earth) at one end where the unit is mounted.
3.b. Connect the shield to earth ground at both ends of the cable, usually when the noise source frequency is over 1
MHz.
3.c. Connect the shield to common of the module and leave the other end of the shield unconnected and insulated
from earth ground.
4. Never run Signal or Control cables in the same conduit or raceway with AC power lines, conductors feeding motors,
solenoids, SCR controls, and heaters, etc. The cables should be run through metal conduit that is properly
grounded. This is especially useful in applications where cable runs are long and portable two-way radios are used
in close proximity or if the installation is near a commercial radio transmitter. Also, Signal or Control cables within
an enclosure should be routed as far away as possible from contactors, control relays, transformers, and other
noisy components.
5. Long cable runs are more susceptible to EMI pickup than short cable runs. Therefore, keep cable runs as short as
possible.
6. In extremely high EMI environments, the use of external EMI suppression devices is effective. The following EMI
suppression devices (or equivalent) are recommended:
6.a. Ferrite Suppression Cores for signal and control cables:
Fair-Rite part number 0443167251 (Red Lion Controls part number FCOR0000)
TDK part number ZCAT3035-1330A
Steward part number 28B209-0A0
6.b. Line Filters for input power cables:
Schaffner part number FN610-1/07 (Red Lion Controls part number LFIL0000)
Schaffner part number FN670-1.8/07
Corcom part number 1 VR3
7. To protect relay contacts that control inductive loads and to minimize radiated and conducted noise (EMI), some
type of contact protection network is normally installed across the load, the contacts or both. The most effective
location is across the load.

7.a. Using a snubber, which is a resistor-capacitor(RC) network or metal oxide varistor (MOV) across an AC
inductive load is very effective at reducing EMI and increasing relay contact life.



7.b. If a DC inductive load (such as a DC relay coil) is controlled by a transistor switch, care must be taken not to
exceed the breakdown voltage of the transistor when the load is switched. One of the most effective ways is to
place a diode across the inductive load. Most RLC products with solid state outputs have internal zener diode
protection. However external diode protection at the load is always a good design
