Cooling Fan Controls
The Protection Switch has a secondary function of providing auxiliary cooling for
the DXC-100. There are three fans in the assembly used for the cooling system.
The
Fan Speed field in the Protection Switch Status Menu indicates the speed of
the fans in response to the ambient temperature and the status of the fans.
When the Protection Switch unit powers up, the fan speed default is
Auto . The
fan speed is based on the temperature inside the Protection Switch, which is
directly related to the room ambient. When the system is at Auto, the fan speed
changes automatically depending upon room temperature. When Auto is on, the
fan settings are as follows:
• Low - below 30 degrees C (86 degrees F)
• Medium - 30 degrees C (86 degrees F) to 40 degrees C (104 degrees F)
• High - above 40 degrees C (104 degrees F)
If the Protection Switch is not in
Auto mode, you can set the fan speed directly
to
Off, Low, Medium or High .
An alarm will occur if one of the following conditions is present:
•
cooler - the fan will throttle down when the temperature cools.
•
fan problem - if there is a problem with one of the fans, an alarm will occur.
Taking the fan out of Auto mode is inadvisable.
