5 Troubleshooting

5.1

Overview

To serve as an aid in troubleshooting the G4 EX, the following chapter will provide
guidelines for the various subsystems within the device.
The chapter contains a troubleshooting flowchart (see Figure 5–1). As the user
follows the logic in this flowchart, they will be directed to specific test instructions
that are found in this chapter or may be directed to the Power Troubleshooting
section or the Communication Troubleshooting flowchart (see Figure 5–7). In
addition to the flowchart, this chapter contains step-by-step procedures for
troubleshooting the G4 EX with or without an installed radio communication unit.

5.1.1 Troubleshooting support

If troubleshooting instructions do not lead to a resolution and assistance is
required, the user can contact the Totalflow Service department:
USA: (800) 442–3097

5.1.2 Visual alarm codes

As noted in Chapter 1, the unit's LCD annunciator displays many different status
indicators that are related to device operations. This section contains information
on those codes that reflect errors or provide information that is useful in
troubleshooting the device. 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.

5.1.3 Sleep mode

Totalflow units are designed to move into a low power mode, Sleep, when an
insufficient supply voltage is present for a period of time. The issue that needs to
be addressed is the reason for the Sleep alarm; waking up the unit will be
insufficient for correcting the problem. As such, issues relating to the system's
power supply should be investigated.

5.1.4 Solar panel

When a solar panel is attached to the 6270 OEU to provide a charging source for
the battery, cleanliness and positioning play an important part as do proper
electrical and cabling techniques. More detailed information on power
consumption can be found at www.abb.com/totalflow.

5.1.5 Communication

Troubleshooting the communications for this unit requires that both pieces of
equipment be tested: the G4 EX comm ports and the communication device. This
is discussed in more detail in the Communications Overview section. Other
communication troubleshooting information is shared in the following categories:
RS-232, RS-485, and RS-422 Communications.
