<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 />
