1.0 GENERAL

MISUSE OF THIS DEVICE MAY CAUSE EXPLOSION AND/
OR PERSONAL INJURY. THESE INSTRUCTIONS MUST
BE THOROUGHLY READ AND UNDERSTOOD PRIOR TO
INSTALLATION OF THE DEVICE.
THIS DEVICE IS FOR MONITORING AND COMMUNICATING
GAS CONCENTRATION LEVELS FOR DATA COLLECTION
OR RECORD KEEPING AND DOES NOT PROVIDE ALARM
SIGNALS.
THE END-USER IS RESPONSIBLE FOR MAINTAINING THE
DEVICE IN FULL, OPERATIONAL CONDITION.
TO ENSURE PROPER INGRESS PROTECTION, THE FRONT
AND REAR COVERS MUST BE INSTALLED, AND FULLY
BOTTOMED OUT AGAINST THE BASE ENCLOSURE (I.E.,
METAL-TO-METAL CONTACT). IT IS RECOMMENDED TO USE
A WRENCH OR ANY TOOL ACROSS THE COVER LUGS TO
TIGHTEN THE COVERS DOWN.
EXPOSURE TO TOXIC GAS MAY RESULT IN LOSS OF
CONSCIOUSNESS OR DEATH. SEE ANNEX 1 FOR TOXIC GAS
SENSOR DETAILS.
COMBUSTIBLE GAS ACCUMULATION IN CLOSED
AREAS MAY CAUSE EXPLOSION, AND RESULT IN LOSS
OF CONSCIOUSNESS OR DEATH. SEE ANNEX 1 FOR
COMBUSTIBLE GAS SENSOR DETAILS.
AVOID DROPPING THE DEVICE AS LOOSENING OF THE
THREADED FLAME-PROOF JOINTS OR PERMANENT DAMAGE
MAY OCCUR.
NEW SENSORS MUST BE CALIBRATED AFTER INSTALLATION
(SEE SECTION 3.2).
WHEN NOT IN USE, THE DEVICE SHOULD BE STORED IN
A CLEAN, DRY AREA AND WITHIN THE TEMPERATURE
RANGE LISTED WITHIN THE DEVICE'S ENVIRONMENTAL
SPECIFICATIONS.

1.1 Device Overview

The device is an explosion-proof and intrinsically
safe, WirelessHART point gas detector used for the
detection and monitoring of harmful gases in air. A field-
interchangeable gas sensor module (see Figure 2) provides
detection of toxic or combustible gas. Gas measurement
readings are communicated along with network and
battery status (see Figure 1) via a local, digital display,
and WirelessHART communication protocol. The device
seamlessly integrates with existing supervisory control
and data acquisition (SCADA) or asset management (AMS)
systems.
Sensor specifications are available online or in Annex
1 which can be downloaded from www.ueonline.com/
