The Display Does Not Scroll As Expected
When power is first applied, the unit should quickly go through startup
and begin cycling through the pre-programmed display items. If the
display does not scroll after startup, disconnect the main power and then
re-connect it. You should see something similar to:
Totalflow 32 Bit XFC
OS Part No. 2102900-001
If the display still doesn’t scroll, try disconnecting the power and re-
connecting it again. If still no success, do the following:
With PCCU32, connect to the unit and establish communications such as
Connect To Totalflow, Entry Mode, etc. Go into Terminal Mode and type
“0.0.0=COLD” (Do not enter quotes). The unit should go through a Cold
Start procedure and begin scrolling. If this does not succeed, call the
number on the back of this guide and talk to a customer service
representative.
