Hydraulic Fan System Controller : HFS - 2
FAQ’s:
Set-up program does not reflect user changes made immediately:-
If the controller is in any mid sequence ( I.e. reverse timer was set to a long period and now a new
shorter period is entered ), the controller will normally only reflect the new settings once the currently
running sequence has ended. The only way to ‘reset’ this type of occurrence is to physically power the
t ll d d th b k O O t 2000 i ti h b t bli h d th controller down and then back up. Once Opto 2000 communications have been re-established, the
new settings will be valid and seen.
The Opto 2000 keeps losing communication or keeps resetting:-
This is normally caused by a bad ‘mechanical’ connection between the Opto 2000 head not being
attached to the controller securely or by the Opto 2000 battery level being to low or external power
supply not being connected.
To remedy Check that the communications head is attached
To remedy, Check that the communications head is attached
firmly, that the two small holes are NOT filled with foreign
matter and that the controller LED’s are not damaged or dirty.
Replace the internal 9V battery or check the external power
supply for connection and operation.
The controller shows an error saying “unit not communicating”:-
This error is reported usually if the PC is connected or the set-up program is started after the controller
is working.
Cycle the controller power ON/OFF to reset the link or wait to see if the communications will
synchronise after a few minutes.
If the problem still persists, look at the Opto 2000 power supply and ensure this is correct.
The controller does NOT recognise open circuits on the valve coils”:-
The controller senses open circuits by passing a very small current all the time through the connected
coils to ensure connectivity and winding integrity. This ‘non reporting’ error is caused by the valve coil
plug having a light bulb fitted that appears to the controller to be an electrical load. Remove the light
bulb or use an LED variety that uses less current.
