<strong>2150EX</strong> Area Velocity <strong>Flow</strong> System<br />

Section 2 Preparation and Installation<br />

2.4 Portable Installations For portable installations, the <strong>2150EX</strong> module is stacked with a<br />

2191EX or 2196EX battery module. It communicates with a computer<br />

or 2100 Series network device via an EX Network Cable<br />

(for potentially explosive atmospheres) and an EX Isolator Cable.<br />

The 2196EX is a rechargeable module for use in gas hazard zones<br />

1 and 2. For detailed information about the 2196EX, turn to<br />

section 2.4.4.<br />

The 2191EX module contains two sealed, replaceable battery<br />

packs for use in gas hazard zones 0, 1, and 2.<br />

2.4.1 Installation Example The following steps may be used as a guide to install a basic, portable<br />

<strong>2150EX</strong> system, including the <strong>2150EX</strong> module, the 2191EX<br />

battery module, and an <strong>AV</strong><strong>2150EX</strong> sensor.<br />

1. Inspect <strong>2150EX</strong> module desiccant (2.4.2).<br />

2. Prepare the Battery <strong>Module</strong>.<br />

a. Inspect the 2196EX or 2191EX desiccant (2.4.2).<br />

b. For the 2191EX, install the battery packs (2.4.6).<br />

3. Assemble the system.<br />

a. Install the <strong>2150EX</strong> module (2.4.3 and Figure 2-4).<br />

b. Attach the <strong>AV</strong><strong>2150EX</strong> sensor cable to the <strong>2150EX</strong> module<br />

(2.7).<br />

4. Install the <strong>AV</strong><strong>2150EX</strong> sensor in the flow stream (2.7.1).<br />

5. Connect the RS232EX cable and connect to the site with<br />

<strong>Flow</strong>link software (2.6).<br />

a. Create the site by Quick Connecting to the stack.<br />

b. Set up the site and module settings.<br />

6. Disconnect from the site and replace all protective caps.<br />

2.4.2 Inspecting the<br />

Desiccant<br />

A desiccant cartridge is inserted into the side of the <strong>2150EX</strong><br />

<strong>Module</strong>. The cartridge is filled with silica gel beads that will<br />

indicate when they are saturated. When dry, the beads are blue<br />

or yellow. As the desiccant becomes saturated, the humidity<br />

levels will increase and the beads turn pink or green. If the<br />

entire length of the desiccant cartridge turns pink or green, the<br />

reference air is no longer adequately protected and the desiccant<br />

must be replaced. Refer to Section 5.4 for replacement instructions.<br />

CAUTION<br />

Operating the <strong>2150EX</strong> and sensor with saturated desiccant<br />

can cause many problems such as unstable level readings and<br />

permanent internal damage. It is important that the equipment<br />

is serviced often enough to prevent the entire desiccant cartridge<br />

from becoming saturated.<br />
