Visible and audible signals
The Ready Lamp [19] is illuminated when the generator is fully charged and ready to flash.
When the energy level is changed, the Ready Lamp [19] and the modeling lights turn off,
indicating that dumping or charging of energy is in progress.
The Ready Control [12] is used to select ready signaling:
• BEEP: A short audible signal indicates that the recycling of the generator is completed.
• BUZZ: An audible signal with several “beeps” indicates that recycling is in progress.
• OFF: Ready signaling deactivated.
If a flash is triggered before recycling or auto dumping, there will be a long “beep”. See also
section Flash before ready function .
Before the generator automatically turns of (after 30 minutes of inactivity), there will a
number of short “beeps”.
flash before ready function
The Flash before ready function makes it possible to flash before the recycling or auto
dumping of the generator is fully completed. When a flash is released before the generator
is 100% ready, there will be a long “beep”, indicating an incorrectly exposed image.
Naturally the flash light may not correspond fully to the set value. The incorrect exposure
of the image may be so small that it makes no significant difference and the image may
still be usable if the catch of the moment was perfect.
Test function
The Test Button [19] is used to test that all light settings are correct and that the functionality
is as expected. When the Test Button [19] is pressed, the generator will flash and the Ready
Lamp [19] will be turned off. When the recycling of the generator is completed, the Ready
Lamp [19] will be turned on again.
USB port
The USB port [9] is intended for firmware upgrade of the generator. The port cannot be used
to connect the Pro-B4 to your PC or Mac via an USB cable.
Safety and protection functions
The Pro-B4 generator is equipped with integrated fans and the casing is made of cast aluminum
to effectively dissipate heat. The fans will automatically start running when the generator is
operating at higher energy levels or when the generator is used in hot environments. If there is a
risk for overheating, the recycling of the generator will slow down or stop. If the generator or the
battery is overheated “ot” will be indicated I the displays. After a while, when the temperature
has decreased sufficiently, the generator will start working as normal again.
The generator automatically shuts down if the battery level is too low, to protect it from
deep battery discharge.
