2150EX Area Velocity Flow Module
Section 2 Preparation and Installation
2-8
WARNING
The sensor mounting ring is a potential isolated charge
carrier. Your installation MUST satisfy earthing
requirements. Refer to IEC 60079-14 section 12.2.4 and IEC
60079-11.
2.4 Portable Installations For portable installations, the 2150EX module is stacked with a
2191EX or 2196EX battery module. It communicates with a com-
puter or 2100 Series network device via an EX Network Cable
(for potentially explosive atmospheres) and an EX Isolator Cable.
The 2191EX module contains two sealed, replaceable battery
packs for use in gas hazard zones 0, 1, and 2.
The 2196EX is a rechargeable module for use in gas hazard zones
1 and 2. For detailed information about the 2196EX, turn to
section 2.4.6.
2.4.1 Installation Example The following steps may be used as a guide to install a basic, por-
table 2150EX system, including the 2150EX module, the 2191EX
battery module, and an AV2150EX sensor.
1. Prepare the Battery Module.
a. Install the battery packs (See section 2.4.2).
b. Inspect the desiccant (2.4.3).
2. Inspect 2150EX module desiccant (2.4.4).
3. Assemble the system.
a. Install the 2150EX module (2.4.5 and Figure 2-6).
b. Attach the AV2150EX sensor cable to the 2150EX mod-
ule (2.7).
4. Install the AV2150EX sensor in the flow stream (2.7.1).
5. Connect the interrogation cable and connect to the site
with Flowlink software (2.6).
a. Create the site by Quick Connecting to the modules.
b. Set up the site and module settings.
6. Disconnect from the site and replace all protective caps.
2.4.2 Install Battery Module
Batteries
The 2191EX Battery Module requires two LTC2191EX 8 volt
lithium battery packs (P/N 68-2000-022) or two SLA2191EX 8
volt lead-acid battery packs (P/N 68-2000-023). These packs are
sealed and explosion protected, so they can be safely installed in
a potentially explosive atmosphere.
WARNING
Substitution of components will impair intrinsic safety.
