‘HFS-J’ Hydraulic Fan System Controller:
The HFS-J is the latest addition to the High Country Tek ( HCT ) family of hydraulic fan control modules. The highly
cost effective HFS-J has enough processing power and input output functionality when operating as a single control
module to support a wide range of hydraulic fan system applications. As with all of the HCT modules, the HFS-J is
packaged in a small rugged enclosure and encapsulated in flame resistant resin to withstand extreme conditions in
the harsh mobile operating environment.
The HFS-J module is ideally suited for today’s hydraulic OEM, distributor or system builder. With both mechanical and
electrical robustness paramount in the design priority, Windows™ compatible easy to use set-up software and full CE
compliance means this one product can through, the many configurations and features available, be used across
multiple platforms, markets and applications.
This units cost effectiveness will become quickly apparent through the reduction in inventory costs and stocking
needs as well as in the reduced costly engineering time taken usually associated with the design to delivery cycle.
Programming of the controller parameters and all diagnostics is done through the RS232 connector pendant. This is a
separate connector from the main power, signal and output connector so that optimization or operational observation
can be carried out without disturbing the cooling system operation. When programming, changes or observation of
the module function is required, connection can be made through a standard computer serial connection, either
directly via a 9 way ‘D’ type connector or through one of the many available USB to serial cables along with the
software program HFS-J and the HCT programming interface cable ( Part No:
999-10075
) is required for
communication from the controller to a Windows™ based PC.
The HFS-J is designed to make the fan system set-up easy to configure and control. The hardware contains the
framework software where the parameters can be changed depending on the user’s needs via the PC graphical user
interface ( GUI ).
The GUI has been organized into various user screens that are logical and simple to understand. Terminology has
been used that is commonplace through the mechanical, hydraulic, mobile and fan drive industry to allow easy
configuration, set-up and running and is intended to cater for a wide range of users with varying levels of computer
familiarity.
This new version of proven controller hardware is ideally suited to equipment upgrades as well as fitment by OEM’s at
machine build time and offers all the necessary features required by today’s modern engines that use the J1939
communications standard.
The controller will take information directly from the J1939 bus for the common temperatures broadcast such as
Engine RPM, Water, Charge air and Transmission temperature making system integration very quick and easy. The
controller allows the user to also have up to 2 additional external inputs from thermistor or temperature switches as
the same time if required, these can be used as fan speed overrides if for example, the engine retarder or
air/conditioning is selected in the vehicle increasing the heat load needing to be cooled.
The HFS-J product is backed by High Country Tek’s industry leading product reliability, easy to use software design
and market leading customer service and technical support as well as on-time delivery while the well designed and
intuitive graphical user Interface (GUI), allows you to program multiple configurable modes of operation available
within the one module.
