Normal Display
The normal LCD display will show the current drive temperature digits (6) in either Celsius or
Fahrenheit. In addition, you should see the “slave” symbol (2), which is always on, the fan symbol
simulating a spinning fan(4), the thermometer symbol (5), as well as the up and down arrow and
SET symbols (7,11,13).
Hard Drive in Use
When the hard drive is being written to or read from the hard drive symbol (1) will simulate a
spinning disk. The rest of the display will be normal as discussed directly above. Notice also that
when hard drive is in use the Blue black lit LED will flicker, giving a quick visual indication of
drive activity.
Hard Drive Usage Display
When you change the mode of the LCD to display hard drive usage time instead of the temperature
display using the SET button, the digit display (6) will show the number of days and hours the drive
has been in use.
Fan Malfunction Display
If the fan is disconnected or stops turning the thermometer symbol (5) will blink, the “alert” symbol
(3) will come on, and an audible alarm will sound. In newer units, this features is disabled and
depends on the actual temperature to be above the setting to cause an alarm.
Temperature Alert Display
If the temperature exceeds the factory setting of 130 degrees F, the screen will show the alert
symbol (3). In addition, the thermometer symbol (5) will blink and an audible alarm will sound.
Programming the Temperature Alarms
From the “Normal” display you can press SET to change the temperature display from Fahrenheit
to Celsius. Use the up or down arrow buttons to make this change. Press the SET key again to
confirm your choice and advance to the Temperature alarm threshold screen.
In the temperature alarm threshold screen, the threshold temperature blinks. Use the up or down
arrow buttons to change the threshold.
Once you’ve set the desired temperature, hold
down the SET key for at least 3 seconds to make the change permanent
. You
should hear two beeps to indicate the setup is complete and the LCD display will return to
“Normal”.
If at any time during the SET process you do not depress any buttons for 15 seconds, the unit will
exit setup mode and return to the normal display. All settings made up to that point will be
cancelled if this happens.
