    Powering the 7200-101 The 5-meter power supply cable included (part number 9975-030) has a circular connector that attaches to the 7200-101 Flow Module front panel at the location marked . The other end has bare wire leads for connection to a 10.5-30 POWER VDC supply (50 W or more capability, 2 A or greater).

    Pressure (kPa), Flow Rate (SLPM), Flow Rate (LPM), Flow Power (V), or Flow Drive (%). Flow Pressure (kPa) is equivalent to the Pressure Drop displayed on the 7200-101 control panel. Flow Power (V) is the voltage applied to the blower motor, and is roughly proportional to the Motor Drive (%).

    Section 1. Overview of the 7200-101 Flow Module Flow Rate Data Output Flow variables can be output via the RS-232 and/or Ethernet ports of the LI-7550 Analyzer Interface Unit. The RS-232 and Ethernet tab are used to set the RS-232 and LI-7200/RS Ethernet port configuration(s) for unattended data collection.
  • Page 19 Section 1. Overview of the 7200-101 Flow Module Flow rate (SLPM or LPM) can also be output via the DAC outputs on the LI-7550 Analyzer Interface Unit. The LI-7550 has the capability to output up to 6 variables on DAC channels 1-6. The DACs tab allows you to configure the DAC output channels by specifying the source channel (e.g.
  • Page 20 Section 1. Overview of the 7200-101 Flow Module For example, to configure DAC #1 to output a voltage signal proportional to Flow Rate (LPM), 18 LPM full scale, select Flow Rate (LPM) under DAC1 'Source', and set 0V = 10, and 5V = 18.

    The flow module requires little routine maintenance. Changing the Fuse The fuse in the 7200-101 case can blow if power is applied with reverse polarity. Open the instrument case and unscrew the fuse cover to replace the fuse. The replacement fuse is a 5 A fast-blow, 125 V, 5x20 mm type, available from LI-COR under part number 439-04214.
