Model 2400S Transmitters with Analog Outputs
Required Transmitter Configuration
6.6.5 Configuring the fault indicator
If the transmitter encounters an internal fault condition, it will indicate the fault by sending a
preprogrammed output level to the receiving device. You can specify the output level by configuring
the fault indicator. See Table 6-15.
Note: By default, the transmitter immediately reports a fault when a fault is encountered. You can
delay reporting faults by changing the fault timeout. See Section 8.9.
6.7 Configuring the discrete output
Note: This section is applicable only if Channel B has been configured as a discrete output. See
Section 6.3.
The discrete output generates two voltage levels to represent ON or OFF states. The voltage levels
depend on the output’s polarity, as shown in Table 6-17
.
Figure 6-9 shows a diagram of a typical
discrete output circuit.

Fault indicator Fault output value
Upscale 10–15,000 Hz (user-configurable; default: 15,000 Hz)
Downscale 0 Hz
Internal zero 0 Hz
None Tracks the data for the assigned process variable; no fault action
CAUTION
Setting the fault indicator to NONE may result in process error due to
undetected fault conditions.
To avoid undetected fault conditions when the fault indicator is set to NONE, use
some other mechanism such as digital communication to monitor device status.
