Power Supply Wiring
Internal Power Supply
The Scanner 2000 microEFM is shipped with a lithium battery pack. To supply power to the instrument,
connect the battery cable to connector J1 on the main circuit assembly (Figure 3.2).
Low-power microprocessor technology enables the Scanner 2000 to operate for an estimated 1 year on a
lithium battery pack. The lithium battery pack is ideal for use in extreme temperatures, although extreme cold
temperatures may reduce battery life.
To maximize battery life,
• operate the Scanner using the following default conguration settings:
– calculation frequency: 1 minute
– logging frequency (interval): 1 hour
– download frequency: monthly
• disconnect the Scanner 2000 from the RS-232 to RS-485 converter when ModWorX Pro software is not
in use. When ModWorX Pro is running, the computer powers the converter; when the software is not run-
ning, the Scanner 2000 powers the converter, causing a current drain to the Scanner battery.
• avoid the following conditions/activities:
– operation at extremely cold temperatures
– use of digital output (pulse or alarm)
– use of analog input without external power (when expansion board is installed)
