SMV800 Modbus User's Guide
Totalizer Reached
Maximum Value.
This bit will be set every
time the Totalizer value
reaches user configured
maximum Totalizer value.
The Process Temperature
input exceeds
the Temperature Upper
Range Limit
(URL) as determined by
the configured
Sensor Type.
The temperature sensor
(Thermocouple or RTD)
has an open input. The
sensor connections may
be disconnected or broken.
The temperature sensor is
reading an out of
range input value. The
value is outside the
limits of Temperature limits
for the
configured sensor type
(LTL to UTL)
The difference between the
Internal Cold
Junction Temperature (CJ)
and the
Processor Core
Temperature (CT)
measured in the
Temperature module is
greater than 10 degrees C.
Totalizer starts from zero
when it reaches the max
value. Warning stays active
until the user
acknowledges the status or
Totalizer status latency
expires whichever comes
first
Check the process
temperature. If the
process temperature
exceeds the range of
the current sensor type,
either correct the
process to an in-range
temperature or
switch to a different sensor
type which is
ranged for the expected
process
temperature range.
Check the temperature
sensor connections for
disconnections or broken
wires. Repair the
sensor connections.
Check that the process
temperature input is
within the range limits for
the configured
temperature sensor (LTL to
UTL). If a higher
temperature range is
required, configure and
connect a different sensor
type to meet the
requirements of the
process.
Verify that the
environmental temperature
is within specifications
