Safety instructions
WARNING:
Do not open enclosures. There are no user-serviceable parts inside.
CAUTION:
In order to avoid deterioration of the color filter of the sensor and potential discoloration of the image
avoid pointing the camera directly toward the sun or other bright source.
CAUTION:
Secure the camera system before the power is applied.
•
Installation must be done by qualified installers, and conform to all local codes.
•
It is the user’s responsibility to ensure that the mounting methods are safe and adequate for the
location.
•
Use only stainless steel (SS) hardware to fasten the mount to an outdoor surface.
•
All servicing must be performed by qualified service personnel. Procedures in this manual do not
require entry into the housing of the camera system. The unit contains potential high voltage. It also
contains sensitive devices that can be damaged by static discharge. To reduce the risk of electric
shock and damage to the unit by static discharge do not perform any servicing other than described
in these instructions. If the unit is defective, please contact the Customer Service Department for
technical assistance.
•
It is the sole responsibility of the installer to provide proper installation in compliance with all local
codes and regulations.

Grounding
6
•
To provide protection against electrical surges induced by lightning, static charges, or any other
cause, the camera and cabling system must be properly grounded to earth. For installation on a
building, the camera must be bonded (that is, provided with a low impedance connection) to the
building’s structural earth ground system. For installation on a metal pole with a proper ground
system at the base, the camera must be bonded to the pole. For installation on a non-grounded or
insulated support, the camera must be grounded with an adequate ground strap or wire between
the camera and a nearby ground system, or to a ground system installed at the base of the support. Failure to adequately ground the camera may lead to failure of the camera. This applies to
low voltage (i.e. PoE cameras) as well as to 115 Vac cameras. Failures due to surges are not
covered by the warranty, as they are not due to defects in material or workmanship, and it is
the installer’s responsibility to meet these grounding requirements.
•
All system cables must be shielded, and the shield(s) must be bonded to earth ground.
6X-1110B

3.1.6  Installation Procedure
Provisions must be made for routing the system cable up to the camera system location:
•
Pole mounting: if the cable routes up through the pole, support the cable inside the pole to strain
relieve the camera connector.
•
Pedestal mounting: route the cable down into the pedestal. The cable must be secured by a strain
relief within the pedestal and must not be allowed to hang free through the pedestal.
The sequence of installation can vary from site to site:
•
Verify that the system cable is accessible for connection to the camera system connector at the
mounting location.
•
Prepare wall for installation: use the mount as a template. Mark and drill holes in the mounting
surface.
•
Install large corner, large pole, and parapet mounts. For mounting on:
•
A corner: Use the mount as a template. Mark and drill holes in the mounting surface. Position the mount over the mounting holes. Secure with 5/16-inch fasteners (not supplied).
Drill a hole for the cable if required. See Figure 6.
•
A pole: Position the pole mount on the pole and secure with the stainless steel mounting
straps (supplied). Use a flat blade screw driver or 5/16-inch socket wrench (not supplied)
to tighten strap screws. See Figure 5.
•
A parapet: Fasten the parapet mount adapter to the structure (see Figure 20):
1. Slip the upper and lower mounting brackets onto the tube assembly. The bracket
with the strap on the lower end is installed last. Seat the bottom of the tube
against the strap and snug the U bolt.
2. Hold the parapet mount assembly against the parapet and position it as far down
as possible, so that the 6-inch flange clears the top of the parapet by one or two
inches.
3. Slide the upper mounting bracket up to the edge of the parapet (or as close to the
edge as practical) and anchor the fasteners securely. Snug the U bolt and mark
the drill pattern.
4. Drill holes, insert fasteners, and secure to parapet.
•
•
Install the adjustable head for a standalone camera system (see Figures 3-7):
•
Attach the mounting bracket to the pedestal or wall mount with four 1/4-20 stainless steel
screws (supplied).
•
Attach the adjustable head to the mounting bracket with the bolt (supplied).
Install the wall mount. For mounting on:
•
6X-1110B
A wall: Position the wall mount over the mounting holes. Attach with four 5/16-inch fasteners (supplied). See Figures 4 and 7.

•
•
18
•
A pole or a corner: Attach the wall mount to the studs on the large pole or large corner
mount and secure with the 5/16-inch nuts and washers (supplied). See Figures 5 and 6.
•
A parapet: Position the wall mount over the flange holes. Secure with four 5/16-inch fasteners (not supplied).
Install the support strut. For mounting on:
•
A wall or parapet: Prepare the surface for the support strut installation. Using the wall
swivel as a template, drill three holes into the mounting surface about 17 inches (430 mm)
from the centerline of the wall mount. See Figures 4 and 7.
•
A corner and pole: Attach the small corner mount to a wall or the small pole mount to a
pole and secure with fasteners (not supplied) or with the stainless steel mounting straps
(supplied). See Figures 5 and 6.
•
A wall, corner, pole, and parapet: Attach the wall swivel to the mounting surface with three
1/4-inch diameter stainless steel fasteners.
•
Attach the clamp swivel to the wall mount with the stainless steel clamp (supplied) and
securely tighten the clamp.
For a standalone camera system:
•
Loosen the bolts on the adjustable head and adjust the pan rotation and tilt angle to the
desired position. Retighten the bolts and lock the mount into place.
•
Connect the system cable to the camera system rear plate.

4.0 Quick Check
NOTE: All graphics contained within this document, including screenshots and other displays, are for reference use
only and are subject to change.
4.1 Control and Viewing of Camera
The WinMPC GUI software is designed to work with the ER8800 Series to view video and control lens and
camera. The software is available as a free download at:
http://www.CohuHD.com/content/downloads. Under Software & Protocol Downloads > Setup Test Applications click Analog WinMPC.
4.2 Checkout Procedure
When power is applied to the camera system the initialization process begins. All CohuHD cameras initialize on power-up using stored default parameters in the camera’s non-volatile memory.
If the camera system does not operate when power is applied, check for:
•
Proper input voltage
•
Proper cable connections
After communication with the camera has been established and the video stream has been started, various
functions must be tested to verify proper operation.

5.0 Maintenance
The system is intended for long-term unattended use, and maintenance requirements are minimal:
•
Clean exterior as needed.
•
Clean the front window on the camera head as needed. Use soft nonabrasive cloth, like terry cloth
or microfiber cloth, and a foaming glass cleaner. If present, clean the wiper blade and inspect it.
Replace the blade if necessary.
•
Check pressure periodically. Occasional pressurization of the camera housing may be required.
See Section 5.1 for more details.
5.1 Camera Head Housing Pressurization
Before shipping from the factory dry packs of desiccant are secured inside the camera housing. The housing is then sealed and purged with dry nitrogen to remove moist air from inside the housing. The purging
process provides an internal relative humidity of five percent or less. The camera housing is then pressurized to approximately 5-7 psi and tested for leaks.
If the camera head housing pressure drops to zero over a period of days, it is likely that a seal is leaking
and the camera system must be returned for servicing.
Pressure Relief Valve
(shown with plastic tubing)
Schrader Valve
NOTE: It is not recommended to pressurize the camera head to greater than 5 psi. In operation, pressure variation between 0.1-10 psi is normal, due to temperature variation and other factors.
6X-1110B
25
5.1.1 Schrader Valve
The Schrader Valve is used to pressurize the housing. To maintain pressure in the barrel, add dry nitrogen
to approximately 5 psi (34 kPa).
5.1.2 Pressure Relief Valve
The Pressure Relief Valve limits the maximum pressure in the camera head to approximately 20 psi (138
kPa).
CAUTION: Exceeding 20 psi can cause damage to the relief valve.
IMPORTANT: Due to high temperature, high altitude, or other reasons, the pressure differential between
the inside and outside of the camera head may increase. The pressure relief valve opens when pressure
rises above 20 psi (138 kPa), allowing excess internal pressure to bleed off. After the camera system returns to normal conditions, the internal pressure must be checked and the camera housing must be pressurized with dry nitrogen to bring the pressure back to approximately 5 psi +/- 1 psi. See Section 5.1.3 for
pressurization procedure.
5.1.3 Pressurizing Procedure
The following items are required for pressurizing:
•
A tank of dry nitrogen with a regulator
•
A hose with an air chuck to connect to the Schrader valve
NOTE: Preferred gas for pressurization is dry nitrogen. Argon is an acceptable substitute. Do not use compressed air, as it may contain oil, moisture, or other contaminants.
Below are steps for recharging the camera housing:
1. Set the regulator gauge to approximately 7-10 psi. (A regulator kit ER2914 and dry nitrogen
rechargeable kit EH8000R are available for purchase.)
2. Remove the plastic tubing from the pressure relief valve, if purge is required.
3. Remove the cap from the Schrader valve, place the air chuck on the Schrader valve and fill the
housing with nitrogen.
4. Carefully lift the poppet on the pressure relief valve and purge the camera housing with dry nitrogen
for a minimum of one minute by manually lifting the relief valve on the rear plate while injecting the
dry nitrogen into the Schrader valve.
CAUTION: Do not use a sharp object to open the pressure relief valve. Use care to avoid damage or
contamination of the valve seat.
5. Remove the air chuck and verify with a pressure gauge that the pressure is 5 psi +/- 1 psi. Press the
pin in the center of the Schrader valve to release extra pressure from the barrel, if needed.
6. Firmly install the cap on the Schrader valve to get a good seat. Cap is required for a proper seal.
7. Install the tubing back on the pressure relief valve if it was removed.
