Product Application Guidelines:
ALWAYS do the following:
• Take a few minutes to FULLY read THESE information / data sheets BEFORE starting.
• Keep High Voltage AC cables separate from Low Voltage DC signal and supply cables.
• Make sure the unit supply voltage is the same as the coils on the valve being driven !
• Ensure that you are aware of the adjustments and consequences on the electronics and hydraulics.
• Make sure you have the correct tools to do the intended job ( i.e. P.C., software ) e.t.c.
• ‘Isolate’ this unit from all other equipment BEFORE any form of welding takes place.
• Check ALL connections to and from this unit to ensure NO short or OPEN circuits.
• Check the units supply voltage is CORRECT, ‘ ELECTRICALLY CLEAN ’ and STABLE.
• Operate the units within specified operating temperature for best & reliable performance.
• Ensure that any unused wires / terminals are terminated safely and not shorted together.
• Isolate the controller if ANY form of battery charging or battery boosting takes place on the vehicle.
• Ensure ALL valve connectors are wired correctly, secure, locked and connected to correct coils.
• Observe the set-up procedures in this manual for best operational results.
• Follow and abide by local and country health & safety standards – protect yourself and others !
NEVER do the following:
• Arc Weld or Charge Batteries with this driver unit connected as damage can occur.
• Attempt to use this unit if you are unsure of electrical OR hydraulic connections or expected operation.
• Attempt to use this unit in Areas where other AC or DC coils HAVE NOT been fully suppressed.
• Use a power supply that is not rated for the correct required O/P current under full load.
• Allow wires TO or FROM the unit to short circuit ( to each other or chassis/cabinet e.t.c. ).
• Attempt to use this unit in areas of intense RF without adequate screening measures.
• Disconnect or connect wires to or from this unit unless it isolated from the power supply.
• Use this unit in temperatures that exceed those specified as operation may be effected.
• Start this unit without ensuring ALL work areas are clear of personnel !
The software has been carefully written to give the user the maximum system configuration flexibility while being
transparent in operation and easy to use, even for novice system builders and operators.
To ensure safety when using the software and to prevent accidental connection to another module that is not a HFS-
J, rules have been written into the software to ensure correct operation at all times:
When the PC running the GUI is first connected to a powered HFS-J, and before any data exchange can be allowed, a
‘Handshake’ takes place that confirms the HFS-J internal software ( BIOS ) is compatible, the serial number and the
HFS-J part number. The GUI then checks to ensure that its own revision is compatible with the module software and
only then allows the PC and the module to communicate and share data.
If at any point during the process above an error or miss-match is detected, the GUI software will NOT allow
communications and will inform the user of the problem via a clear message in the ‘Status’ window.
