Hydraulic Fan System Controller: HFS Electrical Specifications 1) Board Style: HCT Unique Size and Mounting. 2) Connector Types: DT15-12PA Deutsch 12 pin 3) Input Supply Voltage: 10 – 32VDC ( Absolute Maximum ) 5) Input Supply Current ( Max ): Valve Current Setting + 200mA Quiescent (Max) 6) Command Input Type(s): 2 wire Thermistor, temperature switch ( software selectable ) 2 x on/off inputs for fan speed override ( software selectable ).
Hydraulic Fan System Controller: HFS Thermistor Requirements: The controller operation is based on input from up to three temperature measured zones. One, two or all three inputs can be used depending on the system requirements with all three thermistor inputs able to be enabled or disabled independently within the set-up software. The inputs can be from NTC ( Negative Temperature Coefficient ) Thermistors or BiMetallic temperature switches and the choice can be made in the set-up software.
Hydraulic Fan System Controller: HFS Switched Inputs ( Fan Speed Override ): These inputs are ON/OFF in nature and are additional to the proportional thermistor inputs. They allow the application to have two „Emergency‟ maximum fan speed selector channels. These inputs can be connected to simple temperature switches and used to give full fan speed if the actuation point of the temperature switch is reached.
Hydraulic Fan System Controller: HFS Fan Control Logic: The controller uses "PI" to regulate the temperatures to be no more than the Set points entered by the user. The „P‟ and I terms act on temperature difference between set point and actual temperatures, with the P term used to change the amount of response at the control valve and should be adjusted to respond smoothly to smaller temperature changes. The larger the number set, the more aggressive the change will be for a small difference.
Hydraulic Fan System Controller: HFS Proportional Output: A variable current output is used for driving a proportional valve to control the fan speed. BOTH wires from the valve coil must be connected to the controller where indicated by „+Prop Valve O/P‟ and „-Prop Valve O/P‟. The output is fully protected against shorted or mis-wired coils with errors being both indicated locally on the associated LED and annunciated on the controller software if the program is running on a PC connected to the unit.
Hydraulic Fan System Controller: HFS Diagnostic Indicators: The unit is fitted with LED indicators to show real time diagnostic information and indicate by error codes in a visual manner the current operational status and if a fault develops with the system, where the fault may be originating from. Power ON / Opto 3000 Transmit LED: The red LED indicates power supply status with the LED „OFF‟ for less than 8 volts and flashes „ON/OFF‟ for more than 40 volts.
Hydraulic Fan System Controller: HFS Error Code Indicator LED: The RED error led that flashes an „Error code‟ when fault conditions that have no other visual indicator have been detected. The LED blinks error codes if faults have been detected with the thermistor inputs, module temperature, module memory and alarm output. The blink code will occur at a rate of 0.5 seconds on and 0.5 seconds off with a two second pause before repeating. Only the highest priority blink code will be displayed.
Hydraulic Fan System Controller: HFS Data Logging Option: The facility exists to allow the user to „LOG‟ data of the thermistors and several other controller functions for later or fault / trend examination. The files can be individually named to suit the application and is suffixed with a *.csv extension for direct and easy reading into Microsoft® Excel® for graphical plotting and mathematical calculations as required.
Hydraulic Fan System Controller: HFS Retry All Faults Option: The user setting “retry all faults” determines if the unit will retry faults that are detected with the controller or peripheral devices after 4 seconds or if NOT selected, the unit will stop operation until the power supply is turned OFF and back ON. If after a power reset, the fault is cleared, the unit will return to normal operation. If the fault persists, the controller will once again stop and repeat the procedure above.
Hydraulic Fan System Controller: HFS Software Set-Up Guide ( Menu Bar ): For added system security, as soon as the Opto 3000 recognizes that the user has connected any powered High Country Tek controller unit, it requests the modules identity to compare to information stored in the graphical user interface. If this identity does NOT match the expected information, the program will display the message seen to the right to inform the user that the unit is not the one anticipated.
Hydraulic Fan System Controller: HFS Software Set-Up Guide ( Menu Bar ): Clicking the DASHBOARD tab brings up the ‘real-time’ controller information page which allows the user to observe the status, alarms and access the diagnostic features. • NO adjustments can be done from this page. Depending on the password level, Clicking the UNIT SETTINGS tab brings up the available user adjustable windows for setting the controller profile. ( shown here at ‘professional’ level with ALL options displayed ).
Hydraulic Fan System Controller: HFS Software Set-Up Guide ( Menu Bar ): At ‘OEM’ and ‘Professional’ password levels only, Clicking the Trouble Codes tab allows the user to observe a log of any OPEN or SHORT circuit error codes that have been triggered and stored. The currently displayed event log can be reset from both of these levels. Event times and number of occurrences are NOT recorded, rather that the error occurred at least once from the last log reset.
Hydraulic Fan System Controller: HFS Software Set-Up Guide ( Menu Bar ): At any password level, Clicking the Help tab allows the user to see contact information, web and e-mail addresses as well as software and hardware revisions for the actual product currently in use. This information should be available if contacting HCT for advice or requesting product support.

Hydraulic Fan System Controller: HFS Software Set-Up Guide ( OEM page ): NOTE: The main differences between the OEM level and the Professional level passwords is the ability at the Professional level to ‘ RESET’ data values in the ‘Permanent Log’ that have been stored during the controllers operation. Both levels allow the user full access to all controller parameters so password confidentiality should be of a high priority.
Hydraulic Fan System Controller: HFS Software Set-Up Guide: 1 Click the ‘down arrow ‘ and select from the menu for ‘Proportional or ON/OFF’ type output current. In ON/OFF mode, no Min, Max, Test or Rev Vlv current settings are available and the output will be dependent on the supply voltage to the controller. 13 1 2 11 3 12 4 In ON/OFF mode the ramps are left active to aide the use of a ‘soft-shift’ valve if used.

Hydraulic Fan System Controller: HFS Controller Mounting: The electronic components used in this controller released by HCT, conform to the Commercial temperature range which is -40° to +75 ° Centigrade. This rating means that the components will work reliably and give a good life span if the operating temperature is kept within these ( absolute maximum ) limits. The controllers when in operation do generate and dissipate internal heat.
