II. QUICK START
BT100/BT200 HANDHELD TERMINAL
Note: If you specified the correct process conditions on your order, these parameters have been preset at the
factory; therefore, there is no need to re-enter the data.
The Style E YEWFLO is a smart communicating device with microprocessor-based technology.
When used with Yokogawa’s BT100 or BT200 handheld terminal (HHT), YEWFLO can be
configured to meet specific application needs. In addition, the optional local indicator/totalizer (TBL
option) allows setting of various parameters.
When in the analog output mode, the HHT may be connected at any point on the instrument's
4-20 mA loop. This connection superimposes a digital signal on top of the instrument’s 4-20 mA
signal making communications completely transparent to your process signal. On the other hand,
since there are no 4-20 mA wires in the pulse mode, direct connection of the HHT to the HHT
PULSE and HHT COM test points on the amplifier is necessary. Once connected, flowrate and total
can be read, tag numbers entered, meter size or any other parameter modified as required.
Additionally, you may activate or deactivate many features of the YEWFLO as necessary to meet
the requirements of your application.
The HHT will enable you to scroll through the program until you locate the parameter that you wish
to change. For communication information, see “How to communicate with the YEWFLO remotely”
in the maintenance section. Please refer to the appropriate HHT instruction manual for details on
each HHT.
To change a parameter using the BT100, insert the removable key in the lock and turn it clockwise
to the ENABLE position. If the key is not in place or if it is in the INHIBIT position, you will receive an
OPERATION ERR message on the display when you press either the INC or DEC key or try to enter
an alphanumeric value in any parameter. If this occurs, insert the key in the lock, turn it clockwise to
the ENABLE position then press either the INC, DEC or alphanumeric key as before.
2.1 PARAMETER SETTING IN BRAIN™ COMMUNICATIONS
The Model YF100*E Vortex flowmeter incorporates BRAIN™ communication functions. These
functions enable the Vortex converter to remotely carry out the following functions by
communicating with the BRAIN™ Terminal (BT100 or BT200), µXL, or Centum-XL distributed
control systems.
•Setting or changing parameters required for vortex meter operation such as tag number, flow span
and process conditions for example.
•Monitoring flowrate, totalized flow and self-diagnostics.
•4-20 mA loop check (simulated output) and totalizer reset.
Note: When the pulse/analog jumpers are set for a pulse output, Remote BRAIN™ communication on the
4-20 mA wires is not available. Therefore parameters cannot be set or read remotely. For the BT100
to operate in the pulse output mode, the instrument must be connected to the test points labeled HHT
Pulse and HHT Com. This allows access to all parameters.
Note: Only the position of the jumpers affects remote communication ability, the software setting of pulse or
4-20 mA has no effect.

BT100 Basic Operation
1) POWER on.
2) First three key strokes will always display “Model No.”, Tag No.”, and “Self-check”.
3) Press MENU key to select desired main menu.
4) Press PMTR key to move down through the selected menu.
5) Once a parameter has been selected, use the INC or DEC keys to review options within the
parameter list. When data input is required, use the alpha key to toggle between the alpha and
numeric characters(A to Z, 0 to 9).
6) Once a parameter has been selected, push ENT twice to save the changes.
Notes: A)Use the ALPHA key to move between alpha and numeric characters.
B) To back up in the programming sequence, push Hkey and then PMTR when in parameter
mode or MENU when in main menu mode.
C) UPLD and DNLDkeys permit copying settings from one instrument in BT100 non-volatile
memory to another instrument.
D) The automatic power-off of the BT100 automatically turns off the power when no key has been
pressed for about 5 minutes. This function is not active during the display A10: Flowrate %, A20:
Flowrate, or A30: Total. The display of these values is updated every 5 seconds.

QUICK START USING THE BT100/200
BT200 Basic Operation
1) Press ON/OFF to activate power.
2) Press ENTER key when prompted.
3) “Model”, “Tag No.”, and “Self-check” will always be displayed next.
4) Press F4 to continue. The main menu list will be displayed next.
5) Highlight the desired menu by using the up and down movement keys. Press ENTER to
access the selected menu.
6) Use the up and down movement keys to highlight the desired parameter and press ENTER to
access.
7) Once a parameter has been selected either:
a)Use the up and down movement keys to review options within the parameter. Once the
appropriate option has been selected, press ENTER twice to edit the selection.
b)Where data input is required, use the alpha key to toggle between the alpha and numeric
characters. Press ENTER twice to save the changes.
Notes:A)The function keys (F1-F4) are used to execute the commands displayed at the bottom of the
screen.
B) Use the left (<) and right (>) movement keys to change whole page of displayed information. The
“<“ key shows the preceding page and the “>“ key the following page.
C) To select a desired alpha character, always use the appropriate SHIFT key. Use the green
shift key to select letters marked in green and the black shift key to select letters marked in black.
If the alpha/numeric keys are not used in conjunction with the SHIFT key, the numeric value
shown on the key will be displayed.
D) To go directly to a particular parameter anywhere in the menu tree while working in a menu, press
either SHIFT key and then press F4. Type the parameter designation (example B24) to be
displayed and press ENTER.
