It provides all information necessary to service, troubleshoot and order parts for this machine.  \nIt is organized into 12 sections.  \nSections 2--4 cover systems operation and troubleshooting procedures.  \nSections 5--7 have location diagrams, drawings of specific circuits and systems schematics.  \nSection 8 has information concerning the electrical connectors used, including removal and replacement.  \nSection 9 contains the parts list with ordering information.  \nSection 10 contains the list of Alerts and Shutdowns.  \nSection 11 contains a list of recommended spare parts for servicing.  \nSection 12 contains software information.  \nSECTION 2  \nGENERAL INFORMATION  \nand  \nOPERATIONAL THEORY  \nGENERAL INFORMATION AND OPERATIONAL THEORY  \nGeneral  \nThe mid--range machine has an electronic monitor and control system to provide discharge air pressure control and engine and package monitor functions. The system uses the WEDGE controller to perform these functions. The electrical system connects all the necessary switches, sensors and transducers to the WEDGE controller in order for it to perform the monitor and control functions.  \nWEDGE Controller  \nThe WEDGE controller is the heart of the machine monitor and control system. It provides data collection, alarming and control functions for compressor operations. It is a microcontroller based unit with analog and digital inputs and outputs.  \nThe WEDGE controller is attached to the back of the control panel. The LED annunciators are part of the front panel of the WEDGE. They can be seen through the laminate on the front of the control panel.  \nThe WEDGE is attached to the control panel with four \\#10 size nuts.  \nThe first function of the WEDGE controller is toscanall analog and digital inputs at a fixed interval. These inputs are scanned every 50 milliseconds. The analog values are then compared against minimum and maximum values and an ALERT or SHUTDOWN is issued, if a value is out of range. The various ALERTSand SHUTDOWNS are listed in Section 10 of this manual.  \nThe second function of the WEDGE controller is machine discharge pressure control. The WEDGE monitors the regulation system air pressure and varies the engine throttle to maintain the setpoint discharge air pressure. The setpoint pressure is set using the regulator on the separator tank.  \nThe third function of the WEDGE controller is to communicate with the diesel engine via the J1939 CAN network. It retrieves diagnostic information over J1939 .  \nWEDGE TO ENGINE INTERFACE CUMMINS ENGINE  \n( 6 )  \n\n| CUMMINS | J4--46\u003Cbr>J4--47\u003Cbr>J4--37 | CAN HI |  | J1--35\u003Cbr>J1--34\u003Cbr>J1--1\u003Cbr>J1--37\u003Cbr>J1--24\u003Cbr>J1--38 | WEDGE CONTROLLER |\n| --- | --- | --- | --- | --- | --- |\n|  |  | CAN LO |  |  |  |\n|  |  | CANSHLD |  |  |  |\n|  |  | KEY SWITCH | |  |  |\n| ENGINE CONTROLLER\u003Cbr>J4--39\u003Cbr>J4--30 |  |  |  |  |  |\n|  |  | FREQ--THT +   | |  |  |\n|  |  | RANGE = 150 Hz (IDLE) to 375 Hz (Full Speed) AT 24VDC |  ","cbCaiuNZ6FESRZDP","https://ap.wps.com/l/cbCaiuNZ6FESRZDP","pdf",5082330,116,"English","# Manual Description\n# General Information and Operational Theory\n## WEDGE Controller\n## Sensors and Transducers\n## Digital Inputs and Outputs\n## Controller Outputs","[{\"question\":\"What is the purpose of the WEDGE controller in the HP750EWCU compressor family?\",\"answer\":\"It provides data collection, alarming, and control functions for compressor operations, using analog and digital inputs and outputs.\"},{\"question\":\"How does the WEDGE controller handle analog and digital input monitoring?\",\"answer\":\"It scans inputs at fixed 50-millisecond intervals, compares analog values to minimum and maximum limits, and issues an ALERT or SHUTDOWN if values are out of range.\"},{\"question\":\"How does the controller communicate with the diesel engine?\",\"answer\":\"It communicates with the diesel engine via the J1939 CAN network to retrieve diagnostic information.\"}]","Electronic Service Manual - HP750EWCU Family of Compressors | PDF",1792763974,292]
