NOTE: 

General Information

The WEDGE controller records and displays diagnostic fault codes for the compressor system 
and the electronic engine. These codes are displayed on the 4-digit LED display on the 
machine control panel. Two of the ten LED diagnostic lamps on the control panel are used with 
fault codes display. One lamp is designated “Engine Fault” and the other “Compressor Fault”. 
When the engine fault lamp is on, all codes displayed are engine faults. When the compressor 
fault lamp is on, all codes displayed are compressor or package related faults.

A list of compressor and engine faults is attached with the placards inside the machine control 
panel and provided in this section. The table of Alert/Shutdown conditions in this section also 
lists the compressor fault codes and a list of the engine fault codes is provided.

The engine diagnostic fault codes can also be read with the manufacturer's service tool. A 
service tool connector is mounted on the engine. This connector provides a connection to the 
J1939 CAN network. For advanced engine troubleshooting, it is recommended that the 
manufacturer's service tools be used with accompanying service literature.
