2.7 SYSTEM TROUBLESHOOTING GUIDE
2.7.1 How to Use This Section
The following sections should be used in diagnosing trouble with your DVS Fast Charging
System. Use section 2.7.3 to relate symptoms to probable causes. Find the symptom that best
describes the problem in the first column and go through the probable causes in the second
column. Then use the third column to identify the appropriate action for that probable cause. See
Section 2.7.5 for a detailed description of each action.
Section 2.7.4 lists fault codes that may be displayed on the front panel of the DVS. Find the fault
code displayed on the DVS and use the table to find a description of the fault code and an action
code.
The last columns in 2.7.3 and 2.7.4 point to specific sections of this manual where further
information related to the faulty component may be found.
Table 3 lists the Charge Termination Codes. This table can be used to interpret charge
termination codes / messages listed in the Charge Event logs.
2.7.2 ESD Precautions
Electronic circuits are sensitive to damage from electrostatic discharge. Persons servicing this
equipment should be trained in proper techniques for avoiding ESD damage to electronic circuits.
As a minimum, when handling circuit boards, wear an appropriate ESD wrist strap connected to
the equipment chassis.
