Transmitter/Alarm General Field Programming Procedure
The following procedure uses the corresponding zero/full-
scale (labeled “Z/FS”) and relay (labeled “RLY”) LED’s to indicate
which parameter is being programmed. A constant ON zero/full-
scale LED refers to zero configuration (scaling input for 0%
output), a flashing ON/OFF zero/full-scale LED refers to full-
scale/span configuration (scaling input for 100% output). A
constant ON relay LED indicates setpoint adjustment, a flashing
ON/OFF relay LED indicates dropout/deadband adjustment.
Refer to Table 4.
CAUTION:
Do not insert sharp or oversized objects into the
switch openings as this may damage the unit. When depressing
the push-buttons, use a blunt tipped object and apply pressure
gradually until you feel or hear the tactile response.
1. Connect a voltage or current source to the input, as required
(refer to Electrical Connections Drawing 4501-640).
2. Apply power and the module’s green “Run” LED will light.
3. Press and hold the
“MODE”
push button until the green
“Run” LED turns OFF and the yellow “Zero/Full-Scale” LED
turns ON. In this mode, the unit is ready to accept a zero
input for the transmitter (scaling input for 0% output). If you
do not wish to change the zero parameter, skip to step 7.
4. Adjust the input source to the zero level according to your
input range (value must be within input range selected).
5. Press the
“UP”
or
“DOWN”
push-button one time to cause
the module to auto-adjust its output level to the
corresponding output zero according to the output range
selected. If the output is not exactly at the zero level, then
each successive depression of the “UP” or “DOWN” switch
will increment or decrement the output signal by a small
amount. Holding the switch depressed will increase the
amount of increment or decrement.
6. Press the
“SET”
push-button to accept the zero value.
Note that every time the “SET” button is pressed, the yellow
“Status” LED will flash once and the zero output will be
captured.
7. Press the
“MODE”
push button one
time. The “Zero/Full-
Scale” LED will flash on/off, indicating that the unit is ready
to accept the full-scale value for setting the span (scaling
input for 100% output). If you do not wish to change the full-
scale parameter, skip to step 11.
8. Adjust the input source to the full-scale level according to
your input range (the value must be within the input range
selected). The module uses the zero and full-scale levels to
set the span (span = full-scale - zero).
9. Press the
“UP”
or
“DOWN”
push-button one time to cause
the module to auto-adjust its output level to the
corresponding full-scale output for the output range
selected. If the output is not exactly at the full-scale level,
t
hen each successive depression of the “UP” or “DOWN”
switch will increment or decrement the output signal by a
small amount. Holding the switch depressed will increase
the amount of increment or decrement.
10. Press the
“SET”
push-button to accept the full-scale value.
Note that every time the “SET” button is pressed, the yellow
“Status” LED will flash once and the full-scale output will be
captured.
11. If you are configuring a model 811T-0500 which has no
alarm, then skip steps 12-17 and jump ahead to step 18.

12. Press the
“MODE”
push button one time until the yellow
zero/full-scale LED goes out and the yellow relay LED turns
ON (see Table 4). In this mode, the unit is ready to accept
an input setpoint level for the alarm. If you do not wish to
change the setpoint, skip to step 15.
13. Adjust the input source to the High or Low alarm setpoint
level.
14. Press the
“SET”
push button to accept the setpoint. Note
that every time the “SET” button is pressed, the yellow
status LED will flash once and the value at the input will be
captured.
15. Press the
“MODE”
push button one time and the yellow
relay LED should start flashing (see Table 4). This means
that the unit is ready to accept the dropout level for the
alarm relay. If you do not wish to change the dropout, skip
to step 18.
16. Adjust the input source to the desired dropout level.
17. Press the
“SET”
push button to accept the input dropout
level. Note that every time the “SET” button is pressed, the
yellow status LED will flash once and the value at the input
will be captured. The module will use the difference
between the setpoint and dropout values to calculate relative
deadband.
18. Press the
“MODE”
push button one time to complete the
program sequence and return to run mode. The green
“RUN” LED will turn ON, the yellow “Zero/Full-Scale” LED
will be OFF, and the yellow alarm LED will be ON or OFF
according to the alarm status. The module will now assume
a transfer function based on the zero and full-scale values
just set. The setpoint and dropout of 811T-1500 units is
used to determine the alarm deadband. Note that until
“SET” is pressed, pushing “MODE” will only toggle between
the zero & full-scale, plus setpoint & dropout adjustment
modes (811T-1500 units), without affecting their values.
Further, if no push-buttons are depressed for a period
greater than 2 minutes, then the module will automatically
revert to run mode (green “Run” LED will light) and no
changes will be made to the original zero or full-scale, and
optional setpoint or dropout settings.
Notes (Field Program Procedure):
1. In field configuration mode, the yellow zero/full-scale LED
(Z/FS) and relay LED (RLY) are used to indicate which
program parameter is being adjusted as illustrated in Table 4:

2. To summarize, the green “Run” LED is turned off in field
configuration mode. The yellow zero/full-scale LED is ON or
FLASHING when the corresponding zero or full-scale value is
being set in field configuration mode and turned OFF in run
mode. The yellow alarm LED is ON or FLASHING when the
corresponding setpoint or dropout/deadband level is being set
in field configuration mode.
