1Introduction
Thank you for selecting a DAISY solution for your hazardous area operator interface
requirements!
This manual describes the general procedures for installing and operating DAISY Model
9016 X-Purge interface systems. The text portion of the manual also includes an overview of
the theory behind the methods used to make electronic systems safe for hazardous areas.
Section 9, Specifications, also contains an overview of system specifications, and Section 10
Drawings, includes mechanical drawings of each unit.
2Hazardous Area Safety Methods: Theory of Operation
2.1 Division 1: X-Purge Protection
X-Purge systems are another option available for Division 1 hazardous areas. The
installation of an X-Purge system on an enclosure in a Division 1 area renders the area
within the enclosure to an essentially non-rated environment. Thus, normally rated
equipment may be installed within the enclosure (within reasonable limits, such as
complying with temperature and power restrictions).
An X-Purge system is fully automated. The system not only provides the protective
purge and maintains positive pressure, but it also automatically controls the
connection and disconnection of power supplies and signal paths. A well-designed X-
Purge system also automatically control flow rates, internal pressure regulation, purge
timing, and switching of states between purge flow and normal operation. DAISY X-
Purge controls provide all of these features.
X-Purge controls must also satisfy the FM 3620: 4.2 specifications. DAISY X-Purged
equipment has also been validated by Factory Mutual as meeting these requirements.

3Pre-Installation Testing
Before installing your system in its final location, you may wish to test it to verify that the
purge system is functioning correctly.
3.1 Division 1 X-Purge Test
IMPORTANT NOTE: Pre-installation testing should always be conducted in a safe area.
Equipment Required
•Clean, dry purge air, or an inert gas supply equipped with local water/oil separator
or filter capable of supplying 40 to 300 SCFH at 30 to 60 PSI.
•Fittings and tubing for purge air or inert gas supply (0.25” NPT Male to connect to
the inlet of the purge system).
•Local air pressure shutoff valve.
•120V, 8A or 240V, 4A AC power (w/ Ground) with pigtails, tinned bare wire and
stripped 0.25”
Procedure
1. PLACE UNIT in a safe area near a source of the purge gas to be used .
2. Install pressure regulator, along with a water/oil separator or filter, a shutoff
valve, a pressure relief valve, and a pressure gauge in the pressurized purge air (or
inert gas) line (see drawing P007).
3. INPORTANT,Bleed the pressurized purge air (or inert gas) line ensuring that any
dirt, moisture, and contaminants are cleared from the line before connecting the
pressurized purge air (or inert gas) line to the unit.
4. Connect the purge gas line to the inlet of the regulator on the Purge Unit.
5. Remove cover of the explosion-proof I/O casting (see drawing P007)
6. Connect an AC power line to the power interface board (see drawing P008). For
connection, location, and wiring, see drawing E017 (NOTE1).
7. Close all access doors and covers.
8. Apply purge gas to the system by opening the shutoff valve. Adjust pressure
regulator on the air-in box (see drawing P008) to 40 PSI.
9. Apply AC power to the unit.
10. When pressure inside the unit reaches 1.0” WC and > 40 SCFH, the Purge Status
LED should illuminate yellow, indicating that it is purging.
IF THE INDICATOR DOES NOT ILLUMINATE a thorough inspection for leakage of
the unit must be made. Panel gaskets can be checked with a soap solution. If
leaks are not visually apparent, verify that the pressurized air is clean, dry and is
40 PSI at the inlet.
DO NOT ATTEMPT TO OPEN THE ENCLOSURE WHILE IT IS PRESSURIZED!
OPENING PRESSURIZED ENCLOSURE CAN RESULT IN SERIOUS INJURY!

11. Slowly increase air pressure with the regulator until the purge process stops.
Note Pressure the pressure at which the purge process stops.
The Purge Status LED will flash red and display an error code -[2 – 2] (over
pressure) or [3 –2] (over-flow).
12. Remove AC power from the enclosure for a minimum of 30 seconds. Decrease
the pressure reading on the pressure gauge by 5 PSI.
This change may vary slightly on some units; if in later testing the unit fails with
an [3 –2] (over-flow) error code, decrease the inlet pressure by another 2 PSI.
Note Pressure for use during start-up.
13. Re-apply AC power. The Purge Status LED will illuminate yellow and should purge
for a minimum of 8 minutes. Time will vary according to the flow rate of the air
into the enclosure.
14. After the purge is complete, the Purge Status indicator will illuminate green.
AC power is now applied to the internal electronics to power on the display or PC.
15. If the purge status light blinks red, refer to Table 6.1 X-Purge Status Light Key on
page 12 for error code details.

4Installation
4.1 PAC-Seal Connection Instructions
A conduit seal is necessary for most equipment enclosures in hazardous areas. Consult
your local codes for full guidance.
It is very important that knowledgeable personnel, familiar with national and local
codes, supervise hazardous area equipment installations.
The sealing compound generally used for PAC-seals is an inorganic, chemically setting,
magnesium oxide base material, which develops a slight expansion while hardening
into a porcelain-like body. Sealing Compound is supplied as a powder and need only
be mixed with water to apply. Approximately one ounce of sealing compound is
needed per cubic inch of space to be filled.
IMPORTANT
•The sealing compound powder has a shelf life of six months when stored in
unopened, tightly sealed containers in a dry location at 70°F.
•Any equipment accidentally splashed with sealing compound should be
cleaned with soap and water before the sealing compound cures.
Equipment Required
•Four PAC-Seal fittings, 1” NPT or 0.75” NPT for the X-Purge (2 for conduit
connection at the enclosure or I/O casting, 2 for connection in the safe area), or
sealing conduits. The PAC Seal and conduit size selected will depend on the size
and number of conductors, which must be run to the unit. Check with NEC tables to
determine the conduit size necessary
•Conduit for electrical signals and for electrical power (separate runs), NEC and NFPA
approved for use in hazardous areas
•NEC and NFPA approved flexible conduit if needed for difficult installations
•Fittings as required for permanent conduit installation NEC and NFPA approved for
use in hazardous areas
•Signal cables, power cables, and connectors as required to mate with the
equipment within the enclosure or cast aluminum box
•AC power switch for use in the safe area
IMPORTANT
ALWAYS follow NEC, NFPA, and local codes when installing conduit and PAC-seals
in hazardous areas!

Procedure
1. Clean threaded surfaces and pour locations should be with soap and water and
thoroughly dried before proceeding.
2. Install two conduit runs (one signal, one power) between the enclosure I/O casting
and AC power source (located ina safe areaorin an explosion-proof box). See
drawing P011 for added details.
3. Shake the sealing compound powder well before mixing with water. The
recommended mix ratio is 5 parts powder to 1-part clean water, by weight.
4. Place 25ml of70°F water into a clean mixing container and gradually add powder to
water whilemixing with a slow-speed mixer orby hand with a spatula until a uniform
consistency isobtained.
•A minimum amount ofwater should be used. Excessive water reduces
mechanical strength, increases shrinkage, and delays set time.
•Failure of the cement toadhere indicates setting has begun. Do not attempt to
re-temper by adding more water.Discard cement andstart a new batch.
5. Apply compound by pouring, casting, orusing a mechanical dispenser. The sealing
compound hardens with an internal chemical-setting action in 18 to 24hours at
ambient temperature. Working time of the sealing compound when the powder is
mixed with water isapproximately 30minutes at 70°F. Ifaccelerated curing is
desired, lowtemperature oven drying at180°Fcan be used. Do not expose the
sealing compound to higher temperatures, constant water immersion, orsteam
environments while curing. If high humidity resistance isrequired in the cured
product, a moisture-resistant lacquer or silicone coating should beapplied to the
exposed surfaces.
6. Place Packing fiber around the ends of each individual wire or cable ends tocreate a
dam for pouring the compound into the PAC Seal. This allows forthe entire contents
of the PAK Seal to be encapsulated by the compound with environmentally safe,
non-asbestos material.
7. LUBT-2 lubricant isrecommended for use on threaded joints. This lubricant is used
to prevent galling of the pipe threads when threading into couplings,junction boxes,
etc. It provides for undamaged male and female threads and a quick release when
parts are being disassembled. The thread lubricant should be a high-quality lubricant
used in temperatures ranging from -40°to +50°F, andis recommended for use in
hazardous locations. The PAC Seal Compound, packing fiber andLUBT-2 areavailable
from Killark at http://www.killark.com/.
8. For enhanced reliability of the Purge unit, an AC line conditioner is recommended.
AC power lines should be no smaller than 14gauge andhave a TRUE EARTH
GROUND.

4.2 Purge Air Line Connection Instructions
4.2.1 For Division 1 X-Purge Systems Model 9016
After the unit has been mounted in its final location in the hazardous area, it
must be permanently connected to a purge air or inert gas line and checked for
leaks and proper operation of the purge/pressurization system. Only when its
pressure integrity has been established should electrical signals and power be
brought “live” to the unit.
ALWAYS follow all NEC, NFPA, and local codes when installing purge systems
in hazardous areas! It is very important that knowledgeable personnel,
familiar with national and local codes, supervise hazardous area equipment
installations.
Equipment Required
•Clean, dry purge air or inert gas supply equipped with local water/oil separator or
filter capable of supplying 40 to 300 SCFH at 30 to 60 PSI.
•Fittings and tubing for purge air or inert gas supply (0.25” NPT Male to connect to
the inlet of the purge system).
•Local air pressure shutoff valve.
Procedure
1. Mount the enclosure in the location in which it will be installed near the source of air or
inert gas to be used for the purge system.
2. Install the pressure regulator, water/oil separator or filter, shutoff valve, pressure relief
valve, and pressure gauge in the purge air or inert gas line (see drawing P011).
3. Bleed the purge air or inert gas line to ensure that dirt, moisture, and other contaminants
are cleared from the line prior to connecting the line to the unit!
4. Connect the purge gas line to the inlet of the regulator on the Purge Unit.
5. The PAC-Seals bringing the power and signals to the explosion-proof I/O casting should
already be installed. Connect the signal lines to the interlock system (see drawings E018,
E019, E022, and E025).
6. Ensure that the power to the AC supply lines is disconnected.Connect the power line(s) to
the X-Purge system (see drawing E017).
7. If the area can be made safe, you may want to test your connections before closing the
explosion-proof I/O casting. If you test the system in place, it is VITAL that you ENSURE
THAT THE AREA IS SAFE during the test and FOLLOW ALL APPLICABLE SAFETY
PROCEDURES for “hot work” in a hazardous area! You can test connections without
purging by holding down the “Bypass Purge” button (see drawing E020) while applying
power; you must release the button within 30 seconds of power application to prevent a
diagnostic error. When the button is released, power and signals are immediately “live” to
the system; you can test operation to make sure that the connections have been made
correctly. Disconnect power IMMEDIATELY upon completion of this test to ensure that the
unit is not erroneously operated in bypass mode!
8. When the signal and power connections are complete, replace the cover on the I/O casting
and secure with the supplied 14 hex-head bolts and torque to 7.5 ft. lbs.
