OOLING FAN
The main cooling fan is a very high-power fan providing the required cooling to the CP SERIES generator's
anode. Due to the high speed and high air displacement volume when the fan is working at maximum
speed, a siren-like sound will be generated. When working in open air conditions, this can be desirable as
it provides for an audible warning when X-rays are emitted. When working in a bunker or closed
environment, this sound can become disturbing. Therefore, the speed of the fan can be controlled by the
PowerBox and 3 setting are made available to the user:
Maximum cooling
The fan will always run at full speed whenever X-rays are generated.
The fan will make a continuous sound and maximum cooling
performance is guaranteed.
Medium
The fan will always run at a medium speed producing a minimal amount
of sound. In this mode, the cooling is however not working at optimal
performance and the generator will interrupt the exposure to cool down
when overheating is eminent.
Silent
The fan will start at a minimal speed, producing almost no sound at all.
During an exposure, as the generator is getting hotter, the fan speed
will increase to satisfy the generator's cooling requirements. In this
mode, you will notice the sound generated by the fan increase to its
maximum in several steps throughout the exposure.
For optimum performance of the cooling system, allow a free exhaust of air from the main cooling fan and
foresee an obstruction-free area of at least 1 meter from the cooling fan.
If dust has accumulated on the cooling fan or underlying heat-sink, clean it with compressed air.

EMORY AND IDENTIFICATION
The CP SERIES generator is equipped with an electronic memory which can store exposure and system
information of up to 5000 exposures. This memory is kept on the CP SERIES generator itself and also
contains the electronic serial number of that generator. The content of the memory is accessible via the
menu of a PowerBox and gives the user access to the complete exposure history of that CP SERIES
generator as well as any error or fault information that may have been stored in it. The contents can be
downloaded to a USB pen drive and sent to ICM for failure analyses. This memory is independent of the
PowerBox or PowerModule that is used so this record can still be accessed even when the PowerBox and
PowerModule the CP SERIES generator was working with failed.
The information stored in this memory are, among other: date and time, the exposure parameters,
measurements of kV, mA and external power source and any error states detected by the PowerBox. This
