Product Overview
General
Basic System
Enclosure
Power Supply
The Thermo Scientific AutoXP / MVT™ is an explosion proof Class I Div 1
flow computer as well as a Multi-Variable Transmitter. The AutoXP flow
computer combines Thermo Fisher Scientific’s long legacy of flow computer
knowledge with all the latest technology, e.g., low power, high speed data
connectivity, and high accuracy. The AutoXP is designed to provide ultimate
flexibility to our customers by providing a unit that can be used as a single-run
flow computer or smart multi-variable transmitter. This unit can be configured
for both gas and liquid applications utilizing today's most common primary
devices.
Both basic and advanced AutoXP systems are placed in an explosion proof
enclosure.

Power
Hardware Description: Basic System
The standard instrument is powered by an external 10–30 Vdc power
supply.
Power consumption of the basic/advanced AutoXP flow computer is about
0.2 ~ 0.4 W for a typical unit; however, overall power consumption
depends upon the I/O configuration and is determined on an individual
basis. Every effort has been made to keep power consumption to a
minimum.
External Power
Source
The voltage range of the standard external power supply is 10–30 Vdc.
See the Installation Guide for installation and wiring instructions.

Aset of theillustrations are provided in this chapter.
The jumper setting for the main board discussed in this section is provided
in Appendix C.
ALithium backup coin cell battery is installed onthemain board (BH1)
tomaintain configuration and memory when power is removed from the
unit. The in-circuit connection of theLithium battery is set by switching
the S1direction toward the front edge of the main board.
Tip Loss ofconfiguration or historical data with the backup battery
installed may indicate that the Lithium battery needs tobereplaced orS1
switch is onoff position. 
Tip The Lithium battery is a field replaceable item. 
Warning The Lithium battery mayexplode if mistreated. Donot attempt to
recharge, disassemble, or burn it. 

Hardware Description: Basic System
Transducer Inputs The expanded I/O board provides two analog inputs for single low-power
transducers (0–5 Vdc maximum range). Other transducers with voltage
output ranges such as 0.8–3.2 V or 1–5 V units may be used with software
scaling provided the 0–5 V limits are not exceeded. Use of 4–20 mA
current loop transmitters is not recommended for units powered from
small battery sources.
All transmitters are wired to analog input channels 1 through 2 on the
terminal board. Maximum cable length between the flow computer and
each transmitter is 25 feet.
Each local analog input provides a transmitter signal input (IN), and a
transmitter signal return (AGND). The analog inputs on the terminal
board are identified in the following Figure 2-3.
