TLTRM MESSTGES
The following alarm messages may appear during operation:
Message
Meaning
Solution
BAD START MEMORY The flash memory for the system did not load and
a default configuration was assumed .
Replace the transmitter .
BAD TEMPERATURE
Temperature was out of range .
Check the process for very low or very
high temperatures .
Check cable connectors for loose connectors or
corrosion
BELOW LOW FLOW
This message indicates that the meter is operating
properly but the flow conditions may be out of
range for your desired operation .
Check the process system for pump or valve
operation if this condition is not expected .
Change the LOW FLOW CUTOFF value, if needed .
CHECK MAN . PRESS .
The manual pressure entry is out of range for the
application .
Program the manual pressure entry to the correct
value and units .
CHECK MAN . TEMP .
The manual temperature entry is out of range for
the application .
Program the manual temperature entry to the
correct value and units .
CHECK TEMP .
This message will display for saturated steam
meters when the temperature in the pipe is below
212° F (100° C) . When the temperature inside
the pipe reaches 212° F (100° C) and greater,
this message disappears and flow rate shows
compensated flow rate and total accumulated
flow .
Check the steam system for proper temperature
and operation . If the steam is at 212° F (100° C) or
greater, check the RTD in the meter .
OVER MAX FLOW
This message displays when the actual flow rate
has exceeded the max flow (20 mA) setting in
the VN2000 Transmitter representing the 20 mA
output . The flow meter continues to display an
unlimited maximum flow rate . However, the
output stays at 20 mA .
Check the process system for pump or valve
operation, if this condition is not expected .
Change the max flow (20 mA) setting, if needed .
HIGH PULSE RATE
The pulse rate is too fast for the hardware .
Check PULSE RATE entry and flow rate displayed .
Lower PULSE RATE to a slower setting .
LOW PULSE RATE
The pulse rate is too slow for the hardware .
Check PULSE RATE entry and flow rate displayed .
Raise PULSE RATE to a faster setting .
NO PRESSURE
If the Pressure Sensor is enabled, then the system
was unable to read the sensor .
Check that a pressure sensor was included in the
vortex sensor .
NO TEMPERATURE
If the Temperature Sensor is enabled, then the
system was unable to read the sensor .
Disconnect power .
Check that the sensor included an RTD .
Check cable connectors for loose connectors
or corrosion .
Remove power from the transmitter and open
the transmitter . With an Ohm meter, measure
the resistance between the gray, white and
pink wires .
Gray and white, 0…3 Ohms
Gray and pink, approximately 100 Ohms
White and pink, approximately 100 Ohms
