3. INSTALLATION

NOTE

All systems are factory are pre-configured and calibrated. All sensors are tagged to indicate the controller (alpha) and the sensor module number (1 - 8).

Identify all components of the system during unpacking

and install using the factory configuration.

The system will power up in a calibrated and fully

functional condition.

3.1 CONTROLLER LOCATION

Rack mounted controllers should be installed in a control room environment where they will be relatively free from dust and temperature extremes. For ease of operation select a rack window space at approximately eye level. Four controllers can be installed side by side in a 19" instrument shelf.

Enclosed controllers for outdoor applications should be located in the most protected location available with consideration for easy access for installation and calibration. The enclosures should be mounted on a vertical surface with the key board at approximately eye level. The enclosure should not face directly into the sun.

3.2 SENSOR MODULE LOCATIONS

Select locations for each of the sensor modules based on the following:

∙Consider the density, relative to dry air, of the gas to determine height of module above floor or ground level:

	Gas	Density
		(Air = 1.00)

	Air	1.00
	Ammonia	0.60
	Carbon Monoxide	0.97
	Chlorine	2.49
	Ethylene Oxide	1.52
	Hydrogen	0.07
	Hydrogen Chloride	1.27
	Hydrogen Cyanide	0.94
	Hydrogen Sulfide	1.19
	Methane	0.55
	Nitrogen Dioxide	1.58
	Oxygen (Air)	1.10
	Sulfur Dioxide	2.26

Specific Gravity of Selected Gases

∙Modules should be placed close to the potential source of gas.

∙Modules should be placed in areas accessible for calibration.

∙Sensors should be pointed down and the conduit should include an inverse trap to reduce moisture (condensation) from accumulating in the electronics enclosure Figure 3-3.

3.3 WIRING

Plan the wiring arrangement to minimize installation expense but with redundancy for critical locations. Wire shall be Belden (or equivalent) 949X (where X = 2, 3, 4, or 5 depending on wire gauge). If high RFI or EMI levels exist wiring should be protected by conduit or shield. Shielded wire shall be Belden (or equivalent) 936X.

NOTE

In no case should the drain wire of shielded cable be used

as one of the conductors.

∙Any modules which are located in a common geographical area a long distance from the controller can be connected to the same three conductor wire run installed from the controller to that area. Table 3-2, Figure 3-4.

∙The remote auxiliary power supply option can be used for installation of one or more modules a long distance from the controller location. The connection from the controller to the remote power supply is via a two conductor "data link" Figure 3-4.

Number of		Maximum length of wire run (feet)

modules	500		1,000	2,000	3,000	5,000

1	20		20	18	16	14

2	20		18	14	12	xx

3	18		16	12	xx	xx
