The Fan tray is located at the bottom of the Control Shelf and provides the cooling
system for the components located in the Control Shelf. The Fan Tray contains three
fans, each fuse protected. The fans force air through a filter to cool the control cards
and power supply units.
The size of each fan is 120x120x80mm and supplies a minimum of 77 CFM at the
rated voltage. The fans operate from the main -48V power supply.
On the back of the fan tray is a connector through which the power and signaling are
connected.
Each fan has a fuse providing electric fault protection. Should a fan malfunction, an
alarm message is immediately displayed on the PI terminal:
FAN FAULT
. The faulty
fan component should be changed as soon as possible.
The technician must determine the faulty component, either one of the fuses has blown
and must be replaced, or one of the fans is not functioning. The fan tray should be
replaced only when the main power to the system is turned
off
.
The alarm signals from the fan to the 32GC card are isolated from the 48V power
source by an opto-coupler device.
Determining the Fan Fault and Replacing the Fan Fuses
When a FAN FAULT alarm has been sent to the PI terminal, the technician must check
the fan tray and isolate the problem to either a faulty fuse or one of the fans.
1.
Remove the Fan Tray fuses one at a time to locate the blown fuse by twisting
the fuse counter-clockwise and removing.
2.
Inspect the fuse. If it is blown, replace with new fuse, by reinserting a new
0.5Amp/250V fuse.
3.
Twist back into place.
4.
If none of the fuses are blown then one of the fans is not functioning (this may
be obvious by simple inspection) and continue with
,
below. Otherwise, the FAN FAULT repair terminates with the repaired fuse.
