By default, the Series 3000 device immediately reports a fault when a fault is encountered. You can
delay reporting faults by changing the fault timeout. Last Measured Value Timeout specifies the time,
in seconds, that the milliamp output will report its last valid measurement after a fault condition has
been detected. After the timeout has expired, the milliamp output will report its configured fault
condition.
8.4.3 Process variable
For the selected milliamp output, select a process variable. The milliamp output level will vary
according to the value of this process variable, within the limits defined by the calibration span
parameters (see the following section).
8.4.4 Calibration span
Calibration span defines the range, scale, and related parameters for the milliamp output. See
Table 8-5.
Table 8-4 Fault indication parameters for milliamp outputs
Parameter Default Description Setting
(1)
(1) The Setting parameter is displayed only if Condition is set to Upscale or Downscale.
Condition / Upscale Downscale • If Condition is set to Upscale, and a fault
condition occurs, the milliamp output will
transmit this level of current.
Range: 21.0 to 24.0 mA
Default: 22.0 mA
Condition / Downscale • If Condition is set to Downscale, and a fault
condition occurs, the milliamp output will
transmit this level of current.
Range: 1.0 to 3.6 mA
Default: 2.0 mA
Condition / Internal
zero
• Goes to the mA value that represents a value of
0.0 for the process variable.
• An apparent value of 0.0 for the process
variable could indicate a fault.
Not applicable
Condition / None • The milliamp output never indicates a fault
condition.
• The milliamp output always transmits process
variable data.
Not applicable
Last measured value
timeout
0 sec • Enter the value, in seconds, that the
Series 3000 device will continue to report its last
valid measurement after a fault condition has
been detected. Range is 0.0–60.0 seconds.
(2)
(2) This parameter can also be set in the frequency output menu. Only one value is stored. If you change the fault timeout in the mA output
menu, the value displayed in the frequency output menu is changed, and vice versa.
Not applicable
CAUTION
Changing the process variable assignment without verifying the milliamp
output range can produce process error.
When the process variable assignment is changed, the milliamp output range
parameters will be changed automatically. The new output range may or may not
be appropriate for the process. To avoid causing process error, always verify the
milliamp output range parameters (LRV and URV) after changing the process
variable assignment. See Section 8.4.4
