3.2 Powering Up
Because the Model XMT868i does not have an ON/OFF switch, it will power up as soon as the connected power
source is energized.
Note:
For compliance with the European Union’s Low Voltage Directive, 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 XMT868i:
•
Built-in LCD display
•
PanaView software on a computer
•
Device to read the XMT868i’s 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 Model XMT868i fails any of the internal checks (see Chapter 2, Error Codes , in the Service Manual ), try
disconnecting the power and then re-powering the unit. If the meter continues to fail any of the internal checks,
contact the factory for assistance.
After successfully performing the internal checks, the Model XMT868i 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 Model XMT868i can display valid data. Refer to Chapter 2,
Initial Setup , for specific
instructions.
CAUTION!
The XMT868i conducts the FRAM (non-volatile RAM) test only on the first powering
up. If the screen displays the message, “Program Memory Fault Detected,” consult the factory
immediately. Otherwise, the XMT868i will not repeat the test and may not properly save
programmed values.
