enison Have Long Recognised the Need for Driver Electronics Which Are Reasonably Priced,
Easy to Apply, Mechanically Sound and Can Be Utilised in Many Differing Environments and With a
Wide Range of Proportional Products.
T
he Ideal Is to Keep Product Variation to a Minimum Which Will Reduce Spares Stocking As Well As
Allowing Commissioning Engineers, System Designers and Machine Operators to Become Familiar With
a Limited Range of Connections and Adjustments Which Will Improve Overall Efficiency, Confidence in
the Electronic and Hydraulic Components and Once Comfortable With the Operation and Parameters,
Will Generate Proven Electro-Hydraulic ‘Building-Blocks’ Which Can Be Used Time and Time Again
Without Extra Design or Production Time Being Wasted on Learning a New Product.
T
his industry and application unique ‘Plug Top Controller’ is specifically designed for
direct connection to
any engine Control Unit ( ECU )
having a proportional Pulse Width Modulated ( PWM ) output for fan
speed control and can be used to directly drive 24V coiled valves requiring upto 600mA drive current.
The 700-00027-0 uses the latest internal component and circuit design technology to give
full CE
compliance
to present
EMC
directives to ensure maximum operational potential and efficiency, while
offering a full IP68 ( NEMA 6P ) rating in
ONE
unique and easy to apply package.
T
his versatile controller has been designed to allow users access to an extremely cost effective driver
device while ensuring that the valve product is controlled to the best possible characteristic.
T
he small size and NEMA 6P / IP68 rating of this unit allows internal OR external applications to be
approached with confidence that some other drivers of this type cannot allow.
T
he following ‘Application Hints’ for this versatile driver unit are only issued as a guide and if required,
further help and /or advice should be sought from your Local distributor or from Parker Denison internal
sales departments.
T
o keep pace with the changing laws on environmental issues, new legislation regarding engine
efficiency while also reducing machine operating costs, the award winning ‘Parker Denison Fan
Controller’ ( DFC ) systems program has now produced a third iteration of the controller ( DFC-3 ) aimed
specifically at on-road, small size, uni-directional, simple cooling systems. By using this 700-00027-0
controller plug and for example, the M5AF the vane motor with integral valving, the cooling system
becomes a two part system where the fan speed is directly controlled by the Engine Control Unit ( ECU )
PWM output.
T
he ECU, PWM output typically operates from 10% to 90% pulse width based on a 5V -28V maximum
system voltage. The PWM frequency can vary from different manufacturers and the 700-00027-0 can
accept frequencies of 20Hz without any adjustment required by the operator.
This ‘Plug Top Driver’ has been designed to interface and operate with:-
Engine OEM Engine Control Unit ( ECU ) PWM outputs from 5-28V at 20Hz
HydraCool™ Fan system pressure control manifold blocks.
Vane and gear motors with integral pressure control valve.
Electrical pressure compensation options on Piston pumps.
Systems with 24V cartridge valves as fluid controlling elements Positive or Negative logic ).
•
Fan systems requiring direct connection to the Engine Control Unit ( ECU ).
• Parker Denison Award winning ‘HydraCool™’ fan systems.
• With Vane or gear motors for 2 part cooling system.
• ANY Single coil proportional pressure , flow or screw-in cartridge control valves.
• Variable piston pump electro-hydraulic stroker coil.
• Mobile applications where ‘CHASSIS’ or ‘EXTERNALLY’ mounted.
• Exposed , ‘Outside’ or harsh environment applications.
• High Vibration and /or ‘G’ force applications.
• High Humidity applications.
• Marine usage.
• System load / Unload valves.
• Pump stroker ( single side operation )
• Applications where ‘Damage’ may occur to exposed electronic components.
