Sauer Danfoss F301, F305, F116, F117, F118 2010 Technical Manual

If you’re chasing a fault on a Sauer Danfoss F301, F305, F116, F117, F118 EH module and the machine is acting up, you need the actual factory document. Not a reprint, not a third-party summary. This is the 2010 Technical Manual – 20 pages of OEM-written procedures and specs for the hydraulic electronic control modules. I’ve spent enough time under hoods to know that guessing on control logic or wiring pinouts costs billable hours and parts. This manual kills that guesswork.

7 Electronic Control Modules Covered

The manual breaks down seven EH module types: EHB mounting base, EHF flow regulation, EHA alarm logic, EHP ramp generator, EHS speed control, plus the general information sections. Each chapter starts with a general description, then moves straight into function, signal monitoring, electrical system principles, and technical data. Page 7 gives you the EHF technical data – reference currents, voltage ranges, and code numbers for ordering replacements. That’s the kind of concrete spec you can trust because it came from Danfoss engineers, not a parts catalog writer.

What’s Inside the 20 Pages?

Twenty pages doesn’t sound like much until you realize every page is packed with factory-defined electrical characteristics. The EHA alarm logic chapter covers monitoring more than eight functions (page 10–11), extra safety circuits, and the mechanical-to-electrical remote operation changeover. The EHP ramp generator section includes two electrical system principle diagrams and ramp time adjustments. You get potentiometer adjustments for the EHS speed control module, including Potentiometer I and II settings. No wasted space, no filler. Just the data a technician needs to diagnose and set up these modules correctly.

Does This Manual Cover the F301 and F305?

Yes. The F301, F305, F116, F117, and F118 all use the same EH module platform covered in this document. The mounting base dimensions (page 6) apply across these models. Code numbers and weight listings are model-specific, so you can identify the correct replacement module. If you’re working on any of these five models and need the factory electrical specs, this is the matching manual. For related drivetrain info, check the Sauer-Danfoss DSW Orbital Motors Technical Manual and the Sauer-Danfoss TMK TMKW 2008 Technical Manual. Also see the Sauer Danfoss Series 90 2008 Technical Manual – OEM Specs if you’re dealing with the hydrostatic side.

EHA Alarm Logic: Extra Safety and Remote Operation Changes

The EHA section is where this manual earns its keep on a jobsite. Page 11 covers extra safety circuits that prevent accidental machine movement during mode changes. The chapter also walks through the changeover between electrical remote operation and mechanical operation – a procedure that, if done wrong, can lock the control unit or cause unintended actuation. The factory procedure shows exactly which terminals to check and what signal voltages to expect. No aftermarket manual I’ve seen includes this level of detail for the EHA module.

Mounting Base and Accessories: EHB Dimensions

Page 6 has dimensional drawings and code numbers for the EHB mounting base. If you’re retrofitting or replacing a damaged base, those measurements matter. The manual lists weight for each base variant. Use those numbers to verify you’re ordering the correct part – saves a return trip to the parts counter. For basic transmission theory behind these modules, refer to Manual Transmission and Manual Transmission for background on hydraulic-mechanical interfaces.

Signal Monitoring and Electrical System Data

Every control module chapter includes a “Signal monitoring” subsection. For the EHF flow regulator, you get characteristic curves and electrical system principles. The EHP ramp generator has detailed electrical system principle 1 and 2 diagrams. These are not generic schematics – they show pin assignments and voltage relationships specific to the Danfoss EH platform. The technical data tables on pages 7, 13, and 18 include input voltages, current draws, and environmental ratings. That’s the data you need to confirm a sensor reading or verify a module’s operating range before swapping parts.

Source Authenticity: OEM vs Aftermarket

I’ve seen too many third-party “equivalents” that swap a pinout or omit a critical note about grounding. This manual is an original Sauer Danfoss publication from 2010, revision AB. The table of revisions shows only two editions – first in 2004, location update in 2010. That means the content is stable and proven. No aftermarket translation errors, no generic diagrams. You’re getting the same document that Danfoss dealers and authorized service centers use. If you want to confirm your hydraulic system is behaving correctly, start here.

Does the manual include wiring diagrams for the EHA module?

It includes electrical system principles and signal monitoring diagrams, but not full factory wiring schematics. The EHA section covers extra safety circuits and function monitoring, with terminal designations and voltage information.

What models and years are covered?

This 2010 technical manual covers Sauer Danfoss electronic control modules for models F301, F305, F116, F117, and F118. The mounting base dimensions and code numbers apply to these five models. Year range is 2004 (first edition) with the 2010 update as document revision AB.

Bottom line: if you touch control modules on Danfoss equipment, this is the reference you keep within arm’s reach. 20 pages of factory spec data that ended a dozen headaches for me. Access the Factory Manual from AutoRepairManuals and keep it on your tablet or printed out – it’s worth the space in the toolbox.
