Cooling and current settings of the Corona II systems must be designed so that temperature at
the heat sink does not exceed maximum operating temperature:
T
max
= 75 °C
If the Corona II system is used with a Chromasens XLC 4 Controller, the temperature inside
the illumination module can be monitored. If the threshold value is exceeded, a cooling system
can be activated, or the illumination can be switched off.
Note that the LED temperature has a strong influence on the degradation of the LEDs light
output.
The Corona II modules are available with several heat sink options to adapt the illumination to
the environmental and operational conditions in the scan system.
It is strongly recommended to mount the Corona II illuminations in a way that free air flow can
provide optimal convection cooling.
4.4 Enviromental conditions for storage and transport
For storage of the Corona II modules, the environmental conditions according to
DIN EN 60721-3-1 (International IEC 721-3-1): IE11
are admissible.
For transport of the Corona II modules, the environmental conditions according to
DIN EN 60721-3-2 (International IEC 721-3-2): IE21
are admissible.
