The Speed Control [18] is used to select one of four recycling speed 
settings:

• 

25 %

 The slow recycling speed is four times as long as the MAX re-

cycling speed. This alternative shall be selected when the generator 
is connected to a mains power supply with weak fuses, when you are 
uncertain as to how well the mains power supply is fused and when 
weak gas generators are used for charging. It may allow tree or four 
generators to be connected to the same wall outlet or fuse group.

• 

50 %

 The fast recycling speed is twice as long as the MAX recycling 

speed. This setting may allow two generators to be connected to the 
same wall outlet or fuse group.

1)

• 

75 %

 The extra fast recycling speed is slightly longer than the ex-

tremely fast MAX recycling speed. It reduces load by 25 % and may 
prevent sensitive types of fuses to blow. The recharge speed is anyhow 
extremely fast compared to other fl ash generators.

1)

• 

MAX

 The extreme and fastest recycling speed. Only one Pro-8a can 

be connected to one wall outlet or fuse group.

1)

• 

It is recommended to use DIM or BEEP-DIM setting of the Ready Control [16]. It reduces mains power 
amperage load during recharging and thereby stress of the fuse. Lack of light is always shorter than one 
second and negligible if MAX recharge speed is set.

f more than one generator is connected to one fuse group it is always advisable to set recharging speed 

corresponding to the fl ash energy used. Settings are optimized if the individual generators get a simul-
taneous ready signal. There is no advantage if one generator with a small fl ash energy setting is much 
faster than a generator with a larger fl ash energy setting. By using individual generator speed settings 
recharge speed can be greatly optimized by greatly by reducing the momentary load from generators 
with small fl ash energy settings and thereby the sum of the momentary load. Some modern automatic 
fuses can be very sensitive to momentary, short, high instant, peak load during the short recharge.

1) Notes to optimize recycling speed in relation to the fuse type and size available.
