Orion 2xx - Manual (Page 21)

When the Model 2xx transmitter is initially powered on,
the measurement engine does not have enough valid meas-
urement cycles to make a decision about the output level.
For the first sixteen measurement cycles after power is
applied, the QUALITY is “Uncertain,” the SUB_STATUS
is “Initial value,” and the LIMIT attribute is “Constant.”
When the Model 2xx is operating correctly, the QUALITY
is shown as “GOOD,” and the SUB_STATUS is “Non-
Specific.”
While changing the transmitter operational parameters
using the local display or through the system configuration
tool (with the MODE_BLK in OOS), the output might be
inaccurate because of the changing parameters. When the
device is in a mode where operational parameters can be
changed, the TRANSDUCER BLOCK will still output
level but the QUALITY will be shown as “Bad” and the
SUB_STATUS is “Out of Service.”
When the Enhanced Jupiter measurement cycle fails to find
a valid output level, the transmitter maintains the last good
value as the output and flags the failure. The LIMIT attrib-
ute is the same as the last good measurement. Excessive dis-
rupted cycles causes the transmitter to go into a defined
operational mode based on the cause of the disrupted cycles.
4.1 Simulation Feature
The Jupiter Model 2xx with F OUNDATION fieldbus ™ sup-
ports the Simulate feature in the Analog Input block. The
Simulate feature is typically used to exercise the operation of
an AI block by simulating a TRANSDUCER block input.
This feature can not be activated without the placement of a
hardware jumper. This jumper is installed as standard on
the Jupiter Model 2xx, and is placed in an inconvenient
location to avoid inadvertent disabling of this feature.
NOTE: A BLOCK_ERR of “Simulation Active” in the Resource Block
does not mean simulation is active—it merely indicates that the
simulation (hardware) enabling jumper is present.
Contact the factory for instructions on how to remove this
jumper and permanently disable the Simulate feature.
