Guidelines
The GSE Models 3501s and 3551s instruments are approved by FM Approvals as intrinsically safe for use in
hazardous areas. An intrinsically safe device has been proven through calculation and testing that it cannot
produce enough electric or thermal energy under normal or fault conditions to cause ignition of flammable
material present in the atmosphere. The hazardous area is defined in terms of how long the hazard is
present, how easily it is ignited, and what maximum temperature can be present.

DURATlON OF HAZARD
US(NEC500) I Division 1
Division 2
T E M P E R A T U R E C O D E S
Class I, Division I, Groups A, B, C & D
Class I, Division 1 locations are those in which hazardous concentrations of flammable gases or vapors exist
continuously,intermittently
or periodically under normal operating conditions. Electrical equipment for use
in such locations may be “explosion proof,” “intrinsically safe,” “purged” or otherwise protected to meet
the intent of Articles 500 of the National Electrical Code@.
Explosion proof protectionconsists of equipment designed to be capable of containing an internal explosion
of a specified flammable vapor - air mixture. In addition, the equipment must operate at a safe temperature
with respect to the surrounding atmosphere.
Intrinsically safe electrical equipment and associated wiring are incapable of releasing sufficient electrical or
thermal energy to cause ignition of a specific hazardous material under “normal” or “fault” operating
conditions. Normal operation assumes maximum supply voftage and rated environmental extremes; fault
conditions assume any single or dud independent electrical faults plus field wiring open, shorts or
connections to ground.Equipment rated as intrinsically safe is recognized by Article 500 as safe for use in
hazardous locations without special enclosures or physical protection that would otherwise be required.
Purged systems have fresh air or an inert gas under positive pressure to exclude ignitable quantities of
flammables from the electrical equipment enclosure.
Equipment Approved for Division 1 locations shall be permitted in Division 2 locations of the same class,
group and temperature class.
2

Class I, Division 2, Groups A, 8, C & D
Class I, Division 2 locations are those in which hazardous concentrations of flammables exist only under
unlikely conditions of operation. As such, equipment and associated wiring which are incapable of reIeasing
sufficientelectrical and thermal energy to ignite flammable gases or vapors under “normal” operation and
environmental conditions are safe to use in Class I, Division 2 locations.
Class I, Zone 0, Groups IIC, fIB & IIA
A Class I, Zone 0 location is a location (I) in which ignitible concentrations of flammable gases or vapors
are present continuously; or (2) in which ignitible concentrations of flammable gases or vapors are present
for long periods of time. Electrical apparatus for use in such locations may be type of protection “ia”
IntrinsicSafety.
Class I, Zone 1, Groups IIC, 1IB & IIA
A Class I, Zone 1 location is a location (I) in which ignitible concentrations of flammable gases or vapors
are likely to exist under normal operating conditions; or (2) in which ignitibleconcentrations of flammable
gases or vapors may exist frequently because of repair or maintenance operations or because of leakage; or
(3) in which equipment is operated or processes are carried on, of such a nature that equipment breakdown
or faulty operationscould result in the release of ignitible concentrations of flammable gases or vapors and
also cause simultaneous failure of electrical equipment in a mode to cause the electrical equipment to
become a source of ignition; or (4) that is adjacent to a Class I, Zone 0 location from which ignitible
concentrations of vapors could be communicated,unless communication is prevented by adequate positive -
pressure ventilation from a source of clean air and effective safeguards against ventilation failure are
provided. Electrical apparatus for use in such locations may be type of protection “d” Flameproof, “e”
Increased Safety, “ib” Intrinsic Safety, “m” Encapsulation, “0” Oil Immersion, “p” Pressurized or “q”
Pow der-Fil led.
Note: Electrical apparatus Approved for use in Class I, Zone 0 locutions shall be permitted in Class I, Zone
1 locations of the same gas group and temperature class.
Class I, Zone 2, Groups IIC, IIB & tlA
A Class I, Zone 2 location is a lmation (I) in which ignitibleconcentrations of flammable gases or vapors
are not likely to occur in normal operation and if they do occur will exist only for a short period; or (2) in
which volatile
flammable liquids, flammable gases or flammable vapors are handled, processed or used, but
in which the liquids, gases or vapors normally are confined within closed containers or closed systems from
which they can escape only as a result of accidental rupture or breakdown of the containers or system or as
the result of the abnormal operation of the equipment with which the liquids or gases are handled, processed
or used; or (3) in which ignitible concentrations of flammable gases or vapors normally are prevented by
positive mechanical ventilation, but which may become hazardous as the result of failure or abnormal
operation of the ventilation equipment; or (4) that is adjacent to a Class I, Zone 1 location, from which
ignitible concentrations of flammable gases or vapors could be communicated. unless such communication
is prevented
by adequate positive - pressure ventilation from a source of clean air and effective safeguards
against ventilation failure are provided. Electrical apparatus for use in such locations may be type of
protection “nA” Non-Sparking, “nC” Protected contacts, “nR” Restricted Breathing or “p” Pressurized.
Note: Electrical apparatus Approved for use in Class I, Zone 0 or Zone I locations shall be permitted in
Class I, Zone 2 locations of rhe same gas gruup and temperature class.
Class II, Divisions 1 & 2, Groups E, F & G
Electrical equipment suitable for use in Class 11 locations, as defined by the National Electrical Code@, is
constructed to exclude ignitable amounts of dust from the equipment enclosure. Approved equipment of this
type has also been evaluated to assure that hazardous sudace temperatures do not exist. Equipment listed as
3

suitable for Class II locations is “dust - ignitionproof” or otherwise designed to meet the intent of Articles
500 and 502 of the National Electrical Code@.
Class 111, Divisions 1 & 2
Class HI lccations are those which are hazardous because of the presence of ignitable fibers or flyings.
Equipment listed for installation in Class ID locations is designed to exclude the fibers and flyings from the
equipmentenclosure
and to function without developingexcessive surface temperatures.
D E F I N I T I O N S
Associated Apparatus - Apparatus,including Category ia and ib apparatus, in which the circuits are not
necessarily intrinsically safe themselves,but which affect the energy in the intrinsically safe circuits and are
relied upon to maintainintrinsic safety. Associated electrical apparatus may be either:
a) Electrical apparatus that has an alternativetype of protection for use in the appropriatepotentialiy
flammable atmosphere.; or
b) Electrical apparatus not so protected and thus not suitable for use in a potentially flammable atmosphere.
ContruZ Drawing - A drawing or other document provided by the manufacturer of the intrinsically safe or
associated apparatus that details the allowed interconnections to other circuits or apparatus. If the intrinsi -
cally safe ox associated apparatus is investigated under the entity concept. the control drawing will indude
the applicableelectrical parameters to permit selection of apparatus for interconnection.
Entity Evaludion Concept - A method used to determineacceptablecombinations of intrinsically safe
apparatus and connected associated apparatus that have not been investigated in such combination.
Harardous (Clrassiflcation) Lmation: A location in which fire or explosion hazards may exist due to an
explosiveatmosphere of flammable gases or vapors, flammable liquids. combustible dust. or easily ignitable
fibers or flyings.
Intrinsically Safe Circuit - A circuit in which any spark or thermal effect, produced either normally or in
specified fault conditions, is incapable, under the test conditions prescribed in this standard, of causing
ignition
of a mixture of flammable or combustible material in air in the mixture’s most easily ignited
concentration.
Nonincendive Circuit - A circuit, other than field wiring, in which any arc or thermal effect produced under
intended operatingconditions
of the equipment is not capable,under specifiedtest conditions, of igniting the
flammable gas - air, vapor - air, or dust - air mixture.
._
E NTITY E VALUATION C ONCEPT
The Model 35015 and 3551s indicators have been approved under the entity evaluation concept, which
allows the interconnection of intrinsically safe devices in hazardous areas even though these devices were
not specifically approved in this combination.This means that not only can the instrument be used with GSE
FM Approved Ioadcells and peripherals,but they can also be used with any manufacturer’s FM Approved
loadcellsand peripherals provided that they have matching entityratings and are approved for the
appropriate
hazardous area.
The criteria for interconnection is that the maximum input voltage and current, which intrinsically safe
apparatus can receive and remain intrinsically safe, consideringfaults, must be equal to or greaterthan the
maximum output voltage and current levels which can be delivered by the associated apparatus, considering
faults and applicablefactors. In addition, the maximum internal capacitance and inductance of the
intrinsically safe apparatus, including ihterconnectingwiring, must be less than or equal to the maximum
allowedcapacitance and inductancewhich can be safely connected to the associated apparatus. If these
4

criteria are met, then the combination may be connected and remain intrinsically safe. If the specific
capacitance and inductance ratings of the wiring are unknown, use a capacitance of 6OpF/ft and an
inductance of 0.2uWft.
When connecting a Model 350IS or 3551s to another intrinsically safe device, the entity ratings must be
compared and satisfy the conditions shown in the following table.

Display
The Model 350 and 355 intrinsically safe indicators are available with a six digit, 7 - segment red LED
display, six digit, 7 - segment black LCD display or 7 - segment backlit LCD display. The Model 350 and 355
IS will display alphanumeric data, but due to the nature of 7 - segment LEDs/LCD and the limitation of six
digits, some information is abbreviated.
All segments and annunciators are illuminated for a brief display test upon power up. The current gross
weight is then displayed in default units.
LED D I S P L A Y
The LED display is a six digit, 7 - segment bright red LED screen with 12 annunciators to show weight
and status information. The SP1, SP2, and SP3 annunciators are red, green, and yellow. Also there is
an annunciator for a third unit under kg. Place the third unit label above the third annunciator (the third
unit is available on both the LED and LCD displays). See page 28 for third unit setup.
