cause the transmitter to enter the fail mode.
NOTE: For a transmitter in the normal acting mode, output corre-
sponding to zero-percent input would be four milliamperes and out-
put corresponding to 100-percent input would be 20 milliamperes.
For a transmitter in the reverse acting mode, output corresponding
to zero-percent input would be 20 milliamperes and output corre-
sponding to 100-percent input would be four milliamperes.
Secondary engineering units are programmable. These units
are in a free form format of seven characters. Program any
seven characters into the transmitter, such as MA or GAL/HR .
These units are used in conjunction with the secondary lower
and upper range numeric values.
Use the up arrow and down arrow keys or the decimal number
keys to select the secondary units.
NOTE: The secondary engineering units are left justified when dis-
played on the local LCD. If desired, enter dummy characters to cen-
ter or right justify the display.
The secondary lower and upper range values of the transmitter
can be set to any range within ±99999. These ranges can be
monitored by the Type STT terminal or displayed on the
optional LCD of the transmitter. The ranges are a function of
the output of the device. Hence, if a nonlinear output is
selected such as square root, the output to the Type STT ter-
minal will be in units representing the nonlinear square root
function. The output can be polled from the device or dis-
played on the optional LCD. These ranges have no effect on the
calibration of the transmitter and are used to report the output
of the transmitter in user-defined units.
This sets the alarm limits for the cell temperature. The default
values are -50.00-degrees Celsius and +120.00-degrees Cel-
sius. Program the alarm limits anywhere between these two
values.
Once a Type PTSD pressure transmitter has been configured,
the configuration that has been loaded into the transmitter
memory may be reviewed by pressing the GET CONFIG key on
the Type STT terminal (refer to the Type STT Smart Trans-
mitter Terminal Instruction). The configuration is not stored
