Take a few minutes to FULLY read THESE information / data sheets BEFORE starting.
Make sure the unit supply voltage is the same as the coils on the valve being driven !
Ensure that you are aware of the available adjustments on the electronics and hydraulics.
Make sure you have the correct tools to do the intended job ( i.e. D.V.M. ) 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 circuits.
'Start' operating a new system at LOW pressure and with SMALL command signals.
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.
Contact DENISON Hydraulics for more information if you are unsure of connecting this unit.
Fit the supplied rubber gasket correctly between valve coil and plug top driver unit.
Keep High Voltage AC cables separate from Low Voltage DC signal and supply cables.
Follow the set-up procedures in this manual for best operational results.
Arc Weld or Charge Batteries with this driver unit connected as damage can occur.
Attempt to use this unit if you are unsure of connections or expected operation.
Attempt to use this unit in Areas where 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 it isolated from the power supply.
Use this unit in temperatures that exceed those specified as operation may be effected.
