7140 INSTALLATION AND OPERATION
1.0 GENERAL DESCRIPTION
This manual pertains to installation of an envi-
ronmental housing. Depending on the model it may
or may not contain an Ethernet camera module.This
manual does not cover the camera module in any
detail since that version of the 7100 series is docu-
mented in two other manuals.
Reference should be made to technical manu-
als 6X-1043 (user manual) and 6X-1044 (reference
manual) for documentation of the Ethernet camera
modules.
1.1 Electrical Characteristics
This manual describes characteristics of the
sealed and pressurized housing.
Electrical characteristics for the environmental
housing primarily relate to the 39 pin interface con-
nector on the rear panel.Table 4 lists each pin func-
tion on this connector.
A model number interpretation diagram is
shown in figure 4.
1.2 Mechanical Characteristics
This environmental (barrel enclosure) version
of this series is available in two configurations.The
710x consists of an environmental barrel without the
accompanying Ethernet camera module.This version
is shipped from the factory without being pressurized
with dry nitrogen since it is assumed that disassembly
will be required to install a Camera module in the
field.
A model 714x consists of the environmental bar-
rel containing one of the Ethernet Camera modules.
This version is sealed and pressurized with 5 psi (34.5
kPa) of dry nitrogen before shipping from the factory.
2.0 INSTALLATION
Section 4 provides instructions related to ship-
ping and handling of this environmentally camera
housing.
2.1 Equipment Supplied
The equipment supplied depends on what has
been ordered. In its most basic form only the Camera
itself is supplied. Item 1 is basic Camera configura-
tion.
1. Environmental barrel housing with attached
mounting base
2. Mating connector for rear panel connector ( see
table 2)
Optional items that are supplied if ordered

1. Power supply. Either 115 V ac or 24 V ac/dc, de-
pending on the version of the Camera.
2. Interconnection cable (figures 10 and 11)
3. Mounting hardware. At least two 1/4-20 threaded
bolts of proper length
These following additional items may be re-
quired depending on the intended application:
4. Controls for zoom lens

6. Controls for serial programming of Camera func-
tions
7. Monitoring device for external low pressure indica-
tion from Camera
8. Model SS-421 Sunshield
9. Technical manual 6X-1043 (camera module opera-
tion)
10. Technical manual 6X-1044 (camera module techni-
cal reference)
2.3 Cabling Requirements
The model 710x and model 714x uses a 39-pin
Bendix type connector for all interconnections with
the Camera (table 2). Only 32 pins are assigned func-
tions for use with various versions of this Camera.
Fewer that 32 pins are used in typical applications.
All electrical interconnections for the Camera pass
though this connector.
2.3.1 Connector Sealing
Even though the Bendix type connector used
on this camera is designed to maintain a weather-
tight seal with its mating cable plug, it is recommend-
ed that for additional protection against moisture
in severe conditions a sealing wrap be used on the
cable and connector at the rear panel of the camera.
Coax-Seal is the recommended product:
www.coaxseal.com
Unites States 1-800-241-8171
or international 1-828-293-2222
This product is available from a variety of com-
mercial supply houses, consumer stores, and in the
U.S. Government supply channels as GSA Schedule
GS-07F-5739R.
This material is a thick tape-like material sepa-
rated by a paper divider in its roll to prevent bond-
ing to itself before use. After this material is wrapped
around a connector it forms a permanent weather-
tight seal.
The cable and connector should be clean and
dry before wrapping with coaxseal.
Use a full wrap of the tape on the cable at the
beginning, then continue with a diagonal half-over-
lap wrap up to the rear panel of the camera and
finally another full wrap at the end of the coverage.
The wrap then should be squeezed slightly to-
gether by hand to remove air gaps and ensure it has
moulded itself to the cable and connector.
This sealer will fuse itself together after a while
and removal will require cutting it off.
Refer to the Coax-seal web site and to the
instructions accompanying this product for more
information .
2.4 Power Requirements
The 710x and 714x series Cameras have two
basic power input configurations depending on the
version:
1. 24 V ac / dc (model 71x4)
2. 115 V ac (model 71x5)
The major difference between these two ver-
sions is the addition of a 115 V ac to 24 V ac power

INSTALLATION AND OPERATION
transformer in the model 71x5.When this transformer
is installed at pins A and M on the rear panel Bendix
connector must be jumpered together.This can be
done either within the cable plug mating with the
Bendix connector or at the other end of the cable
in the control box assembly, junction box, or other
device that may be used.
Figure 10 shows a cable wiring diagram where
all connector pins associated with power inputs are
carried through the cable to a control panel, junction
box, or similar housing or device.This cable can be
wired at that end for use with either the 24 V ac/dc or
115 V ac versions of the housing.
WARNING
If 24 V ac is applied to a Cable wired for 115 V
ac operation (having the jumper across pins A
and M) 115 V ac will be back-fed out of pins W
and V. This jumper must be removed if a 115 V
ac Camera is to be operated from 24 V ac.
Note that while a 115 V ac housing can be oper-
ated from 24 V ac/dc this results in a condition where
115 V ac is back fed out of the housing onto pins W
and V. To prevent this, the jumper across pins A and M
must first be removed so that this condition does not
exist.
Figure 11 shows a cable wiring diagram for a 115
V ac version of the cable in which pins A and M are
jumpered together within the cable plug attached to
the rear panel Bendix connector..This wiring arrange-
ment should be used when the housing is optioned
with the 115 Vac transformer.This cable cannot be
used to power the housing from 24 V ac/dc because
one required 24 volt wire is not carried through the
cable.
Refer to figure 12 for a
schematic diagram of the hous-
ing.This diagram shows the
internal power wiring of the
housing and also the inter-
connections with the camera
module.
In sum, then:
1. 115 V ac line (high/hot) applied
to pin W and the neutral applied
to pin V. Pin X is the ac power
ground. When this version of the
camera is to be operated from 115
V ac power, pins A and M must be
externally jumpered together.
2. 24 V ac or 24 V dc applied to pins A and d.When 24
volts is to power the camera ensure that pins A and M
are not jumpered together — especially when the op-
tional 115 V ac power transformer has been installed in
the housing.
2.5 Mounting Requirements
Five 1/4-20 threaded holes are available on the
base for mounting a Camera. See figure 2. At least two
of these holes should be used. If the camera is to be
mounted outdoors it is likely the sun shield (figure 3)
will be required.This must be attached to the cam-
era before it is mounted to a pole, wall, or other type
device.
2.6 Camera Module Characteristics
Any one of seven different versions of an inter-
nal camera modules may be installed in the housing
(table 3).These modules have different operating
characteristics as listed in the table.
2.7 Low Pressure Indicator (Option)
The housing is initially pressurized to about
5 psig (pounds square inch gage) (34.5 kPa) of dry
nitrogen. It is possible that this pressure may dissipate
over time, but so long as even a minimal amount of
the dry nitrogen pressure remains in the housing the
camera can be considered operational.When pres-
sure drops to about 1 psig, though, it may be best to
reapply dry nitrogen to bring pressure up to about 5
psig again.
To provide an indication of low pressure, the
housing can be optioned with a low pressure sensor
that provides two indications when pressure drops

to about 1 psig [6.9 kPa]: (1) This circuit initiates relay
contact closure that appears on pins j and k of the
rear panel connector and (2) it also causes a red LED
to turn on behind the window at the front of the
housing.
2.7.1 Relay Contacts
A reed relay is used to provide the contact
closure when low pressure is detected.These con-
tacts should not be used to switch more than 250
mA. Maximum switching voltage should not exceed
100 V dc. Steady state (unswitched) current should be
limited to 600 mA.
CAUTION
Capacitive loads and incandescent lamp loads draw
very heavy currents when switched on. Do not apply
a load of either of these types without being sure
that they do not exceed the 250 mA switching limit
specied for the relay.
A typical incandescent lamp can draw 10 times
its rated current when power is first applied. In situ-
ations where capacitive loads or incandescent lamp
loads are to be applied, be sure to carefully investi-
gate the switching currents involved.

during that interval. If the housing does lose pressure, a tank of water will likely be required to nd the leak.

10 6X-1047b
7140 INSTALLATION AND OPERATION
a module requires that the housing be accessed
through the rear panel and then reassembled after
the camera module has been installed.
Refer to figure 12, the housing schematic dia-
gram, for internal connections to a camera module.
2.8.1 Opening the Housing
Always depressurize the housing before pro-
ceeding with disassembly.The housing should be
opened only from the rear. Proceed as follows:
1. Release nitrogen pressure from the housing either
by lifting the pressure relief valve pop-up cap or by
removing the cap from the Schrader valve and de-
pressing the valve stem. Accessing the pop-up cap will
require removal of the clear tubing sleeve over it.This
sleeve protects it from accidental release of pressure.
2. Remove the Snap Ring Locking Screw (figure 5) us-
ing a 5/32 inch Allen/hex wrench.
3. Note the O-ring on this hex screw. Place this screw
in a safe location so that the O-ring does not get dam-
aged unless it is to be replaced.
4. Use a flat blade screw driver to begin prying the
internal snap ring out of its groove in the barrel.
5. Continue to slide the screw driver around the
circumference of the housing until the snap ring has
been removed.

INSTALLATION AND OPERATION
6. Hold the housing firmly while pulling back on the
rear panel until the assembly slides out of the housing.
7. Note that at the rear of the removed assembly there
is an O-ring pressure seal. It should be protected from
accidental damage unless a new O-ring is to be in-
stalled. (The O-ring under the finger stock at the front
of the removed assembly is not a pressure seal.)
8. Place the external housing and the interior assem-
bly on the workbench making sure that they cannot
roll off on the floor and be damaged.
2.8.2 Desiccant Packs
The housing should not be reassembled with-
out fresh desiccant packs being installed.This can ei-
ther be fresh, dry packs from a sealed container or the
existing packs that have been removed and properly
dried in a convection oven and then stored in a small
closed container if not immediately used.
2.8.2.1 Drying Desiccant Packs
New desiccant packs or packs that have ab-
sorbed moisture can be reactivated by baking for a
minimum of 16 hours at 105±5 °C (221±41 °F).
Allow to cool for 5 to 10 minutes and then place
in a tightly sealed container for storage.This con-
tainer should not be too much larger that required
to hold the number of packs that have been dried
otherwise the packs may absorb moisture from air in
the container.
A pack can be left in open ambient air for an
hour or so during installation procedures if necessary.
2.8.3 Closing the Housing
Before the housing can be reassembled several
preparatory steps must be completed:
1. Fresh, dry desiccant packs must be available
2. The humidity indicators at the front of the assembly
Figure 7 . Front Window Features
(all humidity indicators should be blue for a
newly sealed and pressurized housing)
Figure 8. Rear Double O-ring Grooves
(install O-ring in groove toward interior of

7140 INSTALLATION AND OPERATION
must all be blue and not have a pink tint. Gently warm
them with a heat gun until they all change to blue. Do
not overheat these indicators.
3. The rear plate O-ring must be cleaned, inspected,
and lightly recoated with Dow Corning No. 111 silicon
grease.
4.The rear plate innermost O-ring groove and mating
surface on the interior of the barrel housing must be
cleaned and then inspected for any scratches, dents, or
other damage.
After any required installation or maintenance
procedures have been completed and bench testing
done, the housing is ready for ready for reassembly.
Proceed as follows:
1. Clean and inspect the interior surface of the barrel
housing where the O-ring will rest when assembled
for any scratches, dents, or other deformities that may
prevent a good seal with the O-ring.
2. Lightly coat the O-ring with Dow Corning No. 111
silicon grease
3. Install the O-ring into the forward most O-ring
groove on the rear panel. See figure 6.This is the
groove toward the inside of the housing.
5. Verify that the grounding finger stock at the front
of the assembly (figure 9) is in place around the large
groove. An O-ring should be under the fingerstock.
This O-ring is not a pressure seal. It should not be
coated with the silicon grease.
5. Install two fresh, dry desiccant packs onto the rail
assembly — being sure they will not interfere with
operation of the camera and lens or the reinstallation
procedure back into the barrel housing.Use tie wraps
if necessary.
6. Insert the front of the assembly (with the finger
stock) into the barrel — being sure that the assembly
is vertically aligned with the base of the housing to
the greatest extent possible. Final alignment to the
base can be done when the camera is operational.

INSTALLATION AND OPERATION
7. Fully insert the assembly into the housing so that
the internal snap ring groove is accessible.
8. Insert the snap ring into its groove starting at the
top right and working around to the top left.
9. Press the snap ring fully into the groove all around
the groove.
10. Do not install the hex head screw to secure the
snap ring in place yet. It will be installed after the
housing is purged of moisture laden room air.
11. Proceed to the Purging and Pressurization proce-
dure.
2.8.4 Purging and Pressurization
After reassembly, the housing can be tested for
leaks either by observing for escaping bubbles in a
tank of water or by checking pressure with a gauge
after 12 hours.This procedure offers both alternatives.
1. Apply dry nitrogen to the Schrader valve for about
one to two minutes — allowing it to flow freely out
the open hole in the rear plate from where the hex
head screw was removed.
2. Verify that the O-ring on the hex head screw is in
good condition or install a new O-ring on the screw.
Lightly coat the O-ring with Dow Corning No. 111
grease.
3. Install the hex head screw into the rear plate. Do
not overtighten.
4. Apply dry nitrogen to the Schrader valve to obtain
5 psig (34.5 kPa) to 6 psig ( 41.4 kPa ) pressure. Record
the exact pressure noted with an accurate low-pres-
sure gauge.
5. Perform step 6 and 7— or alternatively steps 8 and
9.Then continue to step 10.
6. Submerge the housing into a tank of water for a
minute or two and observe for any signs of leakage
from the housing as would be noted by bubbles from
sealed areas at the front and rear of the housing.
7. After verifying that the housing does not have any
pressure leaks remove it from the water tank and
continue to step 8.
8. Dry the Bendix connector pins and interior of the
connector with either gentle compressed air or cotton
tipped sticks.Then continue to step 10.
9. Allow the housing to sit for at least 12 hours then
check pressure again and verify that it is within a
pound of the pressure previously recorded in step 4.
10. Verify that the humidity indicators inside the front
window of the housing are all blue — indicating that
humidity inside the housing is below 10 percent.
11. Perform an operational test on the camera to
verify that it is ready to be released for service.
12. Correct any misalignment of the camera related to
the base by loosening the stainless steel straps and ro-
tating the housing slightly as required.Then retighten
the straps.
13. Release the housing for service.
3.0 OPERATION
Nearly all operating functions of the Camera
relate to the internal Ethernet Camera module. Refer
to the user technical manual (6X-1043) and reference
technical manual (6X-1044).
The only operating function of the Environmen-
tal housing version of the Camera not covered in
those manuals is the low pressure indicator.
The LED behind the front window will illuminate
red if the barrel loses pressure. Also, a contact closure
(pins j and k) will be available through the rear panel
connector.
Once the barrel has been recharged to 5 psi
(34.5 kPa) with dry nitrogen the LED will turn off and
the contacts will open.

be noted on the freight bill or express receipt and
the notation signed by the carrier’s agent. Failure to
do this can result in the carrier refusing to honor the
claim.
When the damage is not apparent until the unit
is unpacked, a claim for concealed damage must be
made. Make a mail or phone request to the carrier
for inspection immediately upon discovery of the
concealed damage. Keep all cartons and packing
materials.
Since shipping damage is the carrier’s respon-
sibility, the carrier will furnish you with an inspection
report and the necessary forms for filing the con-
cealed-damage claim
4.2 Static Discharge Protection
Procedures in this manual do not require entry
into the housing of the Camera. However in the event
that an open unit were available, the following pre-
cautions should be followed:
CAUTION
This Camera contains sensitive devices that can be
damaged by static discharge. Use appropriate static
control methods when working inside the Camera.
Components used in modern electronic equip-
ment, especially solid state devices, are susceptible to
damage from static discharge.The relative suscepti-
bility to damage for semiconductors varies from low
with TTL to high with CMOS. Most other semiconduc-
tors fall between TTL and CMOS in susceptibility to
static discharge. As a minimum, therefore, observe
the following practices when working inside this or
any other electronic equipment:
1. Use conductive sheet stock on the work bench
surface.
2. Connect the sheet stock to ground through an 1
megohm or greater value resistor.
3. Use a wrist strap connected to ground through an
1 megohm or greater value resistor when working at
the bench.
4. Maintain relative humidity of the room above 30
percent.This may require a room humidifier. Working
on circuits with relative humidity below 30 percent
requires extraordinary procedures not listed here.
5. Use antistatic bags to store and transport an ex-
poses chassis, circuit boards, and components. Use
new antistatic bags. Old, used bags loose their static
protection properties.
This list serves as a reminder of the minimum
acceptable practices. Be sure that all static discharge
devices at the work bench are properly installed
and maintained. Standard grounding mats and wrist
straps purchased for use at work benches are sup-
plied with leads having current limiting resistors for
safety. Never substitute with a grounding lead not
having the resistor.
4.3 Preparation for Shipment and
Storage
For storage periods exceeding about one
month, seal the unit in a vapor-proof bag containing
a fresh desiccant pack.
Maintain the Camera storage environment
within a range of -30 to 70 °C (-22 to 158 °F).
For shipment, package with enough foam pad-
ding or other packing material to prevent damage
that can occur during shipping.The original shipping
carton is a good container if it has not been damaged
or subjected to excessive moisture. For shipping to
the factory by Common Carrier, use the following
address:
Cohu Electronics
3912 Calle Fortunada
San Diego, CA 92123-1827
Please contact the Customer Service Depart-
ment for a Return Authorization (RA) number before
sending any shipments to the factory:
or
858-277-6700 extension 261
Prominently display the RA number on the out-
side of the shipping container(s) and on paperwork
contained inside.Give a brief description of why the
equipment is being returned and list the symptoms
of any problems being experienced with the equip-
ment.
