For the above reasons we do not recommend mixing the use of Acute and ProHeads,
especially on 230V markets, if you have a mixture of Pro-7, Acute and D4 generators.
The D4 is as default set to be compatible with Acute heads (Acu). If you wish to change
the default setting please follow the procedure below:
1 . With the generator activated, disconnect the mains cable and any heads connected.
2 . Press and hold down the 3 centre buttons shown in the image below.
3 . Connect the power cable.
4 . Wait for the Aux function display (In the right hand corner) to display Pro. (It will
first display which radiomodule (optional) is installed, then the default head
configuration =Acu, then it will change to Pro) After “Pro” is displayed, 3 short
beeps confirm the new setting.
5 . Release the 3 buttons and the generator is now configured for Pro-7 series heads.
If you need to check which default setting the D4 has, unplug the D4 generator when acti-
vated (power on) then re-plug it and check the Aux function display which will show for
2 seconds Acu (If configured for Acute heads) or Pro (If configured for ProHeads).
WARNING: At 100-120V power supply there is a risk of overheating if old Pro-3,
Pro-5, Pro-6, PF, PB or Pro-7 heads is used even if the generator is set to “Pro”
configuration, because the fans will only r un at a slower than desirable speed.
How to connect heads
One, two, three or four lamp heads can be connected to the sockets marked A, B, C
and D [9]. When connecting the lamp head plug, align the white dots on the plug with
the white dot on the generator panel. Secure by turning the locking ring on the plug
clockwise. If the generator is connected to the mains, and turned on a green dot in the
right corner of the
Power Display(s) [10] will indicate that the head is connected properly.
With Profoto’s special head connection it’s possible to plug and unplug heads safely even
if the generator/outlet is activated.
