2-1 Temperature Control Jumper Settings
Jumpers JP7 and JP8, located on the rear PCB panel of the
VPM-6248T, are used to set the cooling fan for controlling the
operating temperature.
The default setting is JP8 pins 1-2 ON,
JP7 OFF. This sets the cooling fan to
always run continuously to
disperse heat when power to the VPM-6248T is ON.
The default setting means that when the power to
only
the
MobileRACK is switched OFF, the cooling fan will still continue to
run. There will always be the continual noise from the cooling fan
that is mounted in the VPM-6248T enclosure.
To provide a quieter working environment, the VPM-6248T is
designed with a built-in adjustable temperature control sensor
which can be set through jumpers. When the operating
temperature set by the jumper is reached, the fan will
automatically turn OFF.
To access the jumpers, remove three screws on the back of the
enclosure and slide the cover off.
Replace the cover after setting the jumpers.
