7.3.8.1 Cold Start
A cold start clears all the data that is stored in RAM as well as resetting all entered variables to their factory default values or to
the values last written to the tfCold drive by the Save and Restore utility. A cold start should be used for new flow computer
installations. This will ensure that all memory is clear and the operating program is at its default settings. Discretionary use of
this procedure is advised.
NOTICE – Loss of data. If performed a cold start will delete all historical data.
7.3.8.2 Cold Start Procedures (Hardware)
To perform a hardware cold start:
IMPORTANT NOTE: Pressing the RESET button with the memory backup battery disabled performs a Cold Start.
When the flow computer has been cold started, the 24-hour clock will be reset to 00:00:00.
Open the flow computer door.
Disconnect the external battery pack charger, CHGR INPUT +/- terminal block J5 (Figure 96:).
Disconnect the battery pack connector from the board BAT CONN connector J1 (Figure 96:).
Disable the memory backup, J13 (Figure 101:) by moving the pin jumper to pins 2 and 3.
Reconnect the 12Vdc battery pack connector to the board BAT CONN connector J1 (Figure 96:).
Observe LCD.
a. If the reset was the display will move through the startup screens and begin to scroll the cold start was successful.
b. If the display does not begin cycling or locks on one of the startup screens, contact technical support for additional
instructions
Reconnect the external battery pack charging source to CHGR INPUT connector J5 (Figure 96:).
Enter all the necessary parameters or load a saved station file. See Chapter 3, XFC
Enable the memory backup J13 (Figure 101:), by moving the pin jumper to pins 1 and 2.
The flow computer has been cold started.
7.3.8.3 Cold Start Procedure (Software)
Where the hardware restart requires physically disconnecting and reconnecting jumpers from the main electronic board,
performing a software restart involves typing in a command in PCCU.
To perform software cold start:
Connect the PC running PCCU32 to the flow computer with either an MMI cable (RS-232), a USB cable or an
Ethernet cable.
Open PCCU.
Select the Terminal button from the toolbar.
Type the following command exactly as shown at the prompt: BOOT=COLD
Press the enter key.
Observe LCD.
a. If the reset was the display will move through the startup screens and begin to scroll, the cold start was successful.
b. If the display does not begin cycling or locks on one of the startup screens, contact technical support for additional
