SECTION 8. DIAGNOSTIC TROUBLE CODES
8.1
INTRODUCTION
This section provides a reference for Diagnostic Trouble Codes (DTC) read from the Multifunction Digital Indicator (MDI). This
section should only be used for machines equipped with a SEVCON Power Module-(ground board software version P1.13 or
higher) or ZAPI Power Module-(ground board software version P1.0 or higher). For more information on any sensors or indica-
tors, refer to the appropriate section for the machine area. Many of the checks below require configuring and using a multime-
ter. Refer to Section 7: General Electrical Information & Schematics for multimeter basics. DTCs are sorted in groups by the first
two digits, which is also the system distress lamp flash code. To troubleshoot multiple DTCs, start with the DTC with the higher
first two digits. The machine is powered by four 6 Volt batteries in series, providing a nominal 24 Volts to the control system.
Some procedures below refer to this nominal voltage (VMN) as 24V. Actual voltage measurements may differ based on the
charge of the batteries.
If a correction is made during a check, conclude the check by cycling the machine power, using
the emergency stop switch.
It may also be helpful to run a system test, ANALYZER -> SYSTEM TEST for intermittent or difficult
problems.

X-CONNECTOR REFERENCES
Throughout the following DTC troubleshooting procedures, electrical connectors are given a three digit identifier number pre-
ceded with an “X” for identifying and locating the specific connector on the machine.
See Section 9.8, X-CONNECTOR ID INDEX for description of "X" connectors and Figure 9-12. on page 9-20, and Figure 9-13. on
page 9-21 for location of "X" connectors on the machine.
Example of "X" connector usage nomenclature:
[X006.21] refers to terminal 21 (pin and socket) of connector X006.
[X006.21.soc] refers to the socket side of terminal 21, connector X006.
[X006.21.pin] refers to the pin side of terminal 21, connector X006.
