The “
UP
” and “
DOWN
” keys can be used to display further information about the sensor’s
performance.
If the display indicates “
Sensor Good
”, use the “
DOWN
”
key to verify the value being
returned by the sensor. The tester display
s the sensor’s value in real world units for verification.
The following table describes the available display starting from the status display described above:
************************************************ Caution *************************************************
Only sensors that display the “
Sensor Good
” message and that are displaying the correct reading
using the real-time display should be used.
************************************************************************************************************
If a sensor is connected that does not provide a valid CMC family code, the sensor may be read, but
in the real-
time display will show the sensor type “
Unknown
” and the units as “
raw
”. This sensor is
not a valid sensor for use on a CMC network.
Key
Function
Description
Down 1
Real-time display
The sensor type and real-time value for the sensor are
displayed in the units suitable for the sensor. Verify the
sensor’s output using this function.
Down 2
Serial number
display
The sensor’s serial number is displayed. The serial
number should agree with the serial number printed on the
sensor’s label.
Up 1
Sensor Power
The sensor power voltage level is displayed. If this voltage
is too low it indicates the sensor is drawing excessive
power.
Up 2
Sensor Data Low
The data low voltage level on the network is displayed. If
this voltage is too high, the sensor has resistance between
the green data wire and the red power wire.
Up 3
Sensor Data High
The data high voltage level on the network is displayed. If
this voltage is too low the sensor has resistance between
the green data wire and the white common wire.
Up 4
Ground Flt Data
The ground fault leakage voltage on the network is
displayed. If this voltage is too high the sensor has
resistance between the metal case and the green wire.
Up 5
Ground Flt Power
The ground fault leakage voltage on the
power wire
is
displayed. If this voltage is too high the sensor has
resistance between the metal case and the red wire.
Up 6
Ground Flt Common
The ground fault leakage voltage on the
common wires
is
displayed. If this voltage is too high the sensor has
resistance between the metal case and the white or black
wires.
