Sensia 3300 EFM, Installation, Operation & Maintenance Manual

Section 2 - Installing the Scanner 3300 EFM
Overview
The Scanner 3300 flow computer is fully assembled at the time of shipment and ready for mounting. The Scanner 3300
is not installed in a hazardous location, and so Sensia recommends that operators configure the EFM after mounting. The
device may be configured via the web interface, using the touch screen controls (refer to Section 4 - Kiosk Display Inter-
face, page 65 ). The Scanner 3300 receives its inputs from either a multi variable transmitter, or directly from a turbine
meter (and pressure transducer, if relevant).
NOTE The kiosk mode can be viewed while one user is logged in to a device. However, only one user may make
changes to the device through the web interface.
CSA Installations
The Scanner 3300 is CSA-certified for ordinary locations. Since this is the case, the installer must ensure that the Scan-
ner 3300 is installed in a non-hazardous area, and the wiring must be done as per the relevant wiring standards. The user
may use copper conductors for wiring.
Wiring Precautions
Ensure all wiring between the hazardous location (where the multi variable transmitter is installed) and the non-hazard-
ous location (where the Scanner 3300 is installed) follows the relevant wiring standards.
CAUTION All field wiring must conform to the National Electrical Code, NFPA 70, Article 501-4(b) for installa-
tions within the United States or the Canadian Electric Code for installations within Canada. Local
wiring ordinances may also apply. The cable used between the Scanner 3300 and other devices
must be either armored MC-HL cable or standard cable routed through conduit.
Multi Variable Transmitter Mounting
The multi variable transmitter (also referred to as the MVT) will have a multi variable transducer attached. It will receive
the inputs from the transducers on the flow line, and transmit that information to the Scanner 3300. The multi variable
transmitter (MVT) may be directly mounted in the flow line, or be remotely mounted on a 2-in. pole using the a U-bolt
provided and the integral bracket, or mounted to a flat, vertical surface (shown in Figure 2.1, page 22 ).
