Section 2—Installing the Scanner 3100 EFM
Overview
The Scanner 3100 ow computer is fully assembled at the time of shipment and ready for mounting. However, Cameron
recommends that operators congure the EFM prior to mounting if the instrument is to be installed in a hazardous area.
The enclosure must be opened to congure the device, either via keypad controls or via software, and once the instru-
ment is mounted in a hazardous area, the cover should not be removed unless the area is void of combustible gas and
vapors.
Hazardous Area Precautions
The Scanner 3100 is ATEX/IECEx-certied (Zone 1) and CSA-certied (Class I, Div. 1) for hazardous area use. Instal-
lation requirements vary, depending on the certication required. Carefully review the following hazardous area require-
ments before installing a Scanner 3100 in a hazardous area.
ATEX Installations (Conditions for Safe Use)
The ATEX-certied standard Scanner 3100 is fully compliant with European ATEX Directive 94/9/EC and has been
evaluated per the following standards:
• IECEx: IEC 60079-0:2011, Edition 6, IEC 60079-1:2007-04, Edition 6, IEC 60079-11:2006, Edition 5, and IEC
60079-31:2013, Edition 2
• ATEX: EN 60079-0:2012, EN 60079-1:2007, EN 60079-11:2012, EN 60079-31:2014
The following instructions apply to equipment covered by certicate numbers Sira15ATEX 1122X and IECEx SIR
15.0049X:
• When removing the conduit plug to t the data transfer socket to the communication adaptor and during data
transfer, the user/installer shall ensure that no explosive atmosphere is present. After data transfer has nished, the
conduit plug shall be retted in accordance with the relevant Code of Practice.
• Under rated conditions, the branching point at the entry point may reach 80 degC (176 degF); therefore, when
choosing cables and cable glands, this shall be taken into account.
• When removing or replacing the internal battery packs, this shall be done in accordance with the user instructions
provided by the manufacturer, and the user/installer shall ensure that no explosive atmosphere is present.
• The user/installer shall install this equipment taking into account any restrictions or special conditions for safe use that
are applicable to the previously certied devices that are used in its construction.
Wiring Precautions
CAUTION In accordance with EN60079-0, Clause 16.6, all cable and cable glands must be rated for 80 degC
(176 degF). The Scanner 3100 may be tted as a remote unit when all the cable entries are tted
with ameproof glands that have been suitably certied by a notied body.
RTD Assembly Options (for Gas and Liquid Flow Runs Only)
The process temperature input is typically supplied by an RTD installed in a thermowell downstream of the primary
differential pressure source. The location of the thermowell should conform to the relative standard to ensure accurate
measurement. Use only an RTD assembly that is tted with a suitably certied, Ex d IIC cable entry gland, such as the
ameproof RTD (Part No. 9A-X-TTXR-0003) listed in Table 7.1—Scanner 3100 EFM Parts, page 87.
