4.2 Powering Up
Because the XGF868i does not have an ON/OFF switch, it will power up as soon as the connected power source is
energized.
IMPORTANT: For compliance with the EU Low Voltage Directive (2006/95/EC), this unit requires an external power
disconnect device such as a switch or circuit breaker. The disconnect device must be marked as such,
clearly visible, directly accessible, and located within 1.8 m (6 ft) of the unit.
There are three methods for obtaining readings from the XGF868i:
•
Built-in LCD display
• PanaView software on a computer
• Device to read the XGF868i analog output
At least one of the above display options must be installed in order to obtain flow rate readings from the meter.
Immediately upon power up the software version display appears. Then, the meter performs a series of internal
checks, which take about 45 seconds, prior to displaying the flow rate data.
Note: If the XGF868i fails any of the internal checks (see Chapter 2, Error Codes , in the Service Manual ), try
disconnecting the power and then repowering the unit. If the meter continues to fail any of the internal
checks, contact Panametrics for assistance.
After successfully performing the internal checks, the XGF868i begins taking measurements and the software version
display is replaced by a measurement mode display. Proceed to the appropriate section for instructions on using the
LCD display and the PanaView display option.
Note: As a minimum, the system and pipe parameters (for each installed channel of a 2-channel meter) must be
entered before the XGF868i can display valid data. Refer to Chapter 2, Initial Setup , for instructions.
