Danfoss Series 45 pumps with electronic torque limiting maximize performance
At Danfoss, we strive to make an impact where it matters most. Our off-highway mobile
hydraulic solutions work more efficiently to maximize performance. As we build out theinfrastructure of our growing cities, we’re also conserving resources — making projects
more affordable and sustainable.
The Danfoss Series 45 pressure compensated/load sensing (PCLS) pump with electronic
torque limiting (ETL) control proactively and automatically maximizes system pressurein milliseconds for the available engine torque while preventing stalls.
This total solution offers a way to differentiate your product through improved easeof use, fuel efficiency and productivity. Plus, we’ve engineered this great leap
forward in pump technology in a way that allows rapid prototyping, exceptional
flexibility and ease of installation that can dramatically reduce time to market.

Stay ahead of customer expectations

Up to22%
more productivity vs.
traditional mechanicaltorque controls.

The rate of technological change is increasing quickly. The user of today’s
heavy equipment demands more intelligent machines that use technology
to improve productivity and efficiency.
Not only does the Danfoss Series 45 PCLS pump with ETL control meet thetrends of today and tomorrow, it offers unsurpassed flexibility and speed
to market that can give your products a competitive advantage as others
scramble to play catch-up.

SERIESEFFICIENCYBy using technology to maximize pressure within the available torque curve,
the Danfoss ETL control delivers these proven benefits: Increases productivity up to 22% over alternative torque controls
Through super-efficient use of engine power, the ETL control helps operators
do more work per hour by eliminating engine stalls and bogging.

 Moves up to 34% more material per gallon/liter of fuelETL enables innovative operating features such as ECO modes and allows
risk-free operation at the lowest brake specific fuel consumption (BSFC).
This can eliminate excessive noise resulting in peak efficiency,
while promoting minimal environmental impact.

 Increase fuel efficiency by up to16%
ETL can reduce fuel consumption without any loss
in productivity. The gains of running the engine
at the lowest brake specific fuel consumption(BSFC) is offset by the increased flow of a larger
pump that can operate without the risk ofstalling an engine — something traditional
torque controls cannot match.

Engine speed signal sent to PLUS+1®
microcontroller. Plug and perform
technology allows the CAN bus signal to
be used for engine speed monitoring.

Simple integration means immediate value
Easy software integration• Pre-programmed hardware for easy system setup• Prove out, demo, and fine-tune your solution with ease
• GUIDE blocks are easily integrated into PLUS+1 systems• A flexible solution that readily integrates into existing on-board electronics

Electrical hardware• 12 V and 24 V configurations• Angle sensor and proven PCLS control with integrated proportional relief valve (PRV)• Continues to operate the work function system as a PCLS pump,even if the electrical signal is lost
ETL is available on 45 cc – 147 cc pumps in 12 V and 24 V configurations

Your engine torque vs. speed curve is
programmed into a PLUS+1 microcontroller.
Pre-keyed MC-12 hardware is also available
and software can be adopted for yourproprietary control systems.

Pump displacement informationis continuously fed to the PLUS+1
microcontroller via the angle sensor— allowing for proactive torquelimiting protection.

PLUS+1 GUIDE software adjusts the pump’s
proportional relief valve (PRV) setting foreach respective displacement at a given
engine speed. GUIDE software blocks areavailable — allowing for easy integration
into existing GUIDE software applications.

The pump's response is regulated by astandard PCLS control with integrated
PRV. If electrical power is lost, the pumpautomatically defaults to normal PCLS
functionality.

the technology into your existing and future machines at www.danfoss.com/powersolutions

Engineered for use in both new and existing equipment
Bring enhanced, state-of-the-art electronics to pumps of any size with the Danfoss ETL control.
You won’t need to resize, reroute or rework any other part or system when you take advantage ofour pre-keyed microcontrollers. Just drop it in, fine-tune the parameters — a process that Danfoss
has reduced from days to just hours — and you’re ready to start experiencing impressive benefits.

Full system integration can beachieved quickly and easily with
the Danfoss ETL GUIDE block andpre-programmed controllers giving
you a significant time-to-market
advantage. The solution is also
PLUS+1® compliant.

The Danfoss ETL control can be fitted into any existing pressure compensated/load sensing
or mechanical torque control (MTC) system. Unlike other PCLS or MTC systems, the Danfoss
solution is not limited by traditional sizing or engine torque constraints, but can operate
in a full range of pump displacement and engine torque curves.

The power of flexibility
Telematics enabled, Danfoss Series 45
axial piston pumps with electronic torquelimiting (ETL) technology allow for vitaldata collection and greater connectivity
to your machines. Lower maintenancecosts and increase uptime with predictive
maintenance and remote service. These areinformation-driven capabilities unavailable
in many competing pumps.
Danfoss Telematics offers easy-to-develop
custom applications. Our PLUS+1 GUIDE(graphical user integrated development
environment) system uses drag-and-drop
editing making application development
simple — even for programmers lacking
formal development training. Now OEMsof any size have the ability to compete
and win with superior product benefits
that enhance their brand through built-intelematics capabilities.

Danfoss ETL control is easy to integrate into new or existing systems. To find out how easy it
can be for you, contact your Danfoss representative at www.danfoss.com/powersolutions.

CENTERSSee ETL control in action
Danfoss developed the ETL control at one of ourthree global Application Development Centers(ADCs). Danfoss ADCs are also a great place toexperience the ETL difference firsthand byusing similar machines with and without ETL
control and comparing performance.
A Danfoss system application engineer (SAE)
can work with you to install ETL on one ofyour machines, which can be tested at theADC under real-world conditions. Danfoss has
committed all the expertise and capabilitiesof our ADCs to helping customers drive more
revenue by capitalizing on many Danfoss
solutions, including ETL control.
