SECTION 6. DIAGNOSTIC TROUBLE CODES
6.1 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 MDI and 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 the MDI or any sensors or indicators, refer to the appropriate section for the machine area.
Many of the checks below require configuring and using a multimeter. Refer to Section 7: General Electrical Informa-
tion & 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 pro-
cedures 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.
