Focus
This section primarily focuses on the electronic/electrical connections,
and issues related to equipment malfunction. The flowchart in
Figure 5–1
may help to determine which tests to begin with. It should be noted, that it
is not intended to cover every issue, but provide general guidance.

Visual Alarm
Codes
As noted in Chapter 1, the units LCD Annunciator area shows many
different status indicators related to device operations. This section
contains info on those codes that reflect errors or provide information
useful in troubleshooting. Alarm codes indicate that an operational
problem exists.
The user is informed of operational problems and operational limit
violations by observing the alarm codes on the right side of the LCD
display.
SLEEP Mode
Totalflow units are designed to go into a low power mode, SLEEP, when
an insufficient amount of voltage is present for a period of time. At issue
here, is locating the reason for the SLEEP alarm, simply “waking up” the
unit will not suffice, therefore issues relating to the systems power supply
should be investigated.
Solar Panel
When a Solar Panel is attached to the XRC to provide a charging source
for the battery, cleanliness and positioning play an important roll, as do
proper electrical and cabling techniques. More detailed information on
power consumption may be found at www.abb.com/totalflow.
Communication
Troubleshooting the communications for this unit requires that both
pieces of equipment be tested; 1) the XRC Comm Ports and 2) the
Communication device. This is discussed in more detail in the
Communications Overview section.
Other communication troubleshooting information is shared in the
following categories:
