General Overview

1. What is a flame path?A flame path is an opening that can be traced from inside the unit to the outside atmosphere.

2. Why is a flame path a special feature?A flame path is designed so that if a spark or explosion happened on the inside of the camera , the precision fit between parts would force it to be extinguished before reaching the outside atmosphere.


Not gas-tight but strong enough to contain an explosion and prevent the escape of flame or heat that could ignite surrounding atmospheres

ExSite

ExSite positioning System consists of 3 major parts:1. Power Module2. Camera Module3. Pan and Tilt Unit

ExSite Power Supply Unit

• IPSXM-2 (24 VAC) and IPSXM-7 (100 – 240 VAC)• Consist of Wire Harness for power, data and video• DIP switch for Protocol Setting


Check for proper seating of the O Ring

** If O Ring is folded, the EX protection is lost.Always double checkO Ring. Replacedamaged O-rings.


• Total weight of the Pan &Tilt Unit is 32kg• Do not damage the power module grooves• Avoid thread damage (EX protection is lost) and please do not apply any silicon solution

Specific Codes

Wiring Installation for ExSite must bebased on local codes or specificindustry requirements.

Introduction of seal fittingConduit seals prevent explosions from spreading through conduit systems and igniting outside atmospheres. When properly installed and filled with a UL-listed sealing compound, they prevent the passage of gases, vapors, or flames from spreading from a hazardous location to a nonhazardous location. This limits explosions to the EX rated enclosure.

Prevent precompression, or “pressure piling,” in conduit systems.

EX rated compression cables and compression glands are an alternatives to sealed conduit installations. This presentation will focus on the more traditional conduit installation.

Introduction of seal fitting

The maximum ambient temperature range is -76°F to 140°F (-60°C to 60°C).

Installation should be done only by qualified personnel and conform to all local codes.

Introduction of seal fitting

1. Run the conductors through the fitting2. Pack the sealing fitting with fiber filler. In horizontal run, place the fiber filling a both ends of the fitting; in a vertical run, fill only the bottom end. Fiber filler is also used to separate the individual conductors so that the sealing compound seals around each conductor.

ExSite Connection Example

ExSite Installation Guideline

• Indirect cable entry

• Increased Safety (Ex e)

• 1.6 meter length potted cable (factory sealed)

IOP Module

• 22X Color and 23X Day/Night (PAL/NTSC)• Standard or With Wiper

IOP Enclosure

To access to the IOP compartment, you need to loosen set screw and remove the back cover

Tool Required:1.5 mm Allen wrenchSpanner wrench

Warning

To avoid thread damage, carefully remove the back of the enclosure. Never use force to remove the back of the camera Enclosure.

• Please do not try to open the:

1.Front Window of the Camera Enclosure2.Top cover of the Pan and Tilt Enclosure3.Please do not use inappropriate tools during installation

Only trained and certified service personnel should perform this task.

ExSite “sharing of best practices”

Improper & Incorrect installation.

Incorrect Installation

Installed without sealing compound & individual wires not properly separated


Improper curing of sealing compound and individual wires not properly separated. No wire twisting should occur.



Plumbers tape should be used to get a watertight seal

Plumbers tape should be used to get a watertight seal


Enclosure back cover and front window opening cover with silicon

corrosion and rusty found on the enclosure , resulted difficulty for repair and mainteance.


Silicon is applied between two modules (pan base and spindle base) thus caused panning obstruction and jammed.


Wrong mixture of compound and improper installation resulted chemical liquid to leak into the power supply area.
