In Scan Mode the DigitalDoc5 scans through all your Temperature
Sensor values and Fan Speed (RPM) for each fan.
In
Fig. 3
it is currently
displaying the RPM reading for Fan Number 2.
It will first cycle through all
the temperatures of each Temperature Sensor (Channel). It displays each
temperature reading for 5 seconds and then cycles to the next Channel.
After it completes all 8-temperature readings (a 40 second cycle) it then
begins showing your RPM Speed readings for each fan. It displays each
fan's RPM speed for 5 seconds and then cycles to the next Channel.
After it completes all 8 channels it returns the DigitalDoc5 to Normal
Operating Mode. To begin another Scan Cycle press the
Scan Button
again.
Alarms And Warnings
Excessive Temperature Warning
1) When the temperature exceeds the set-point value, the system will
activate a warning beeper and the corresponding channel number will
flash.
2) Pressing any button turns off the warning beeper; at which time the
system will record the warning temperature level.
3) After the warning beeper has been turned off, if the temperature in that
channel continues to rise another 5 C, then the system will activate the
warning beeper a second time.
4) If the warning beeper is turned off a second time, then the system will
not issue another warning message for that channel, unless the
temperature drops back below the set-point, at which time the function is
again operable.
Fan Problem Indicator
1) Fan problem monitoring is limited to the speed function of active fans.
2) When the fan is being monitored, and a discrepancy is discovered in
the fan speed, or the speed drops below 500 rpm, the system will activate
a warning beeper.
3) When the override fan control is in operation, if the fan monitor is not
connected, or if the fan has a 2-pin connector, the system will issue a
warning beeper. Therefore, if no fan is connected or you are using a 2-pin
fan, please turn that fan's monitoring function to [Dis], and there will be no
error in operation.
4) You can press any button to turn off the fan error warning beeper.
Note
:
It takes
approximately 80 seconds
to scan all 8 Temperature
Sensors and 8 Fan RPM
Speed channels. If a fan
is not running, then 0
RPM will show for that
Channel.
Tip
:
If an Alarm is
sounding you can press
any button on the
DigitalDoc5 to turn it off at
any time.
