Symbol Explanation
This symbol represents the
OPERATIONAL DISPLAY�
This is the PROGRAM button�
This is the UP button�
This is the DOWN button�
When a button is shown, press and
release it to go onto the next step in the
direction indicated by the arrow� When two
or more buttons are shown, each with an
arrow, this indicates that there is a number
of programming choices�
When two buttons are shown side by side
and enclosed by a dotted line, they must
be pressed at the same time then released
to go onto the next programming step.
If the display is shown with XXXX it means
the value displayed will be the previously set
value� When a number is shown it indicates
the initial factory default setting or a specific
“example number”.
P
P
When two displays are shown together with
bursts, this indicates that the display is
toggling (flashing) between the name of the
function and the value�
Text or numbers shown between square
brackets in a procedure indicate the pro-
gramming code name of the function or the
value displayed on the meter display�
When the
and buttons are shown
together, the display value can be increased
by pressing and releasing the
button
or decreased by pressing and releasing the
button�
When the
and buttons are shown
with two displays, either display can be
selected by pressing and releasing the
or
buttons�
When there are more than two display selec-
tions they are shown in brackets below the
first display and are also selectable by press-
ing and releasing the
or buttons�
A dotted box indicates these functions are
omitted or bypassed when the related hard-
ware is not present
To explain software programming procedures, logic diagrams are
used to visually assist in following the programming steps� The
fol-lowing symbols are used to represent various functions and
associated display elements of the meter:
[LhLh]
[hLhL]
[LLLL]
Front Panel Buttons
Program Button
The
P
button is used to move from one program step to the next.
When pressed at the same time as the button, it initiates the
calibration mode� When pressed at the same time as the but-
ton, it initiates the setpoint setting mode�
Up Button
When in the operational display, pressing the button alone,
allows you to view and reset the Peak and Valley (Highest and
Lowest Readings�)
When in the calibration mode or the setpoint setting mode the
button is used to increase the value of the displayed parameter�
Down Button
When in the operational display, pressing the button alone,
allows you to view, but not change, the setting of setpoint 1,2,3
& 4�
When in the calibration mode or the setpoint setting mode the
button is used to decrease the value of the displayed parameter�

The BL-40PSF-PROCESS is an intelligent meter with a hier-
archical software structure designed for easy programming
and operation, as shown below in the software logic tree�
After the meter has been powered up, the
four digits light up for three seconds and
then settle to the operational display indicat-
ing the input signal�
15 Second Program Timeout
The meter has a 15 second program timeout� If
no buttons are pressed for 15 seconds, at any
stage of the programming sequence the meter
will exit the programming mode and return to
the operational display� Any program changes
that were made prior to pressing the
P
button
in the preceding step will not be saved�
Software Logic Tree

Texmate, Inc. Tel. [phone] • www.texmate.comPage 4 BL-40PSF-PROCESS Manual (d0074)
The BL-40PSF-PROCESS meter may be rescaled without applying an external signal by changing the Offset and Scale factor.
Offset is the reading that the meter will display for a zero input� The Offset may be set to any value from -1999 to +9999� The
default value of the Offset is 000
Scale factor is the gain of the meter� The displayed reading is directly proportional to the Scale factor� The default value of the scale
factor is 2000, but it may be set to any value between -1999 and +9999�
For an input of 2V a calibrated meter will read 2000 with the default Scale factor of 2000, 3000 with a Scale factor of 3000 and 500
with a Scale factor of 500
If a linear scale is represented by mx + b, then the Scale Factor corresponds to the slope ‘m’ and the Offset corresponds to the
intercept ‘b’
The internal Signal Span is limited to 3 V DC between – 1 V DC to + 2 V DC. Outputs from an Input Signal Conditioning module
that exceed these limits will cause the meter to indicate overrange.
Note: Most input signal conditioners have provisions for analog calibration and scaling. If the meter’s digital Scale Factor is set to
2000 and Offset set to 0000 then, any pre-calibrated signal conditioner with an output that does not exceed – 1 V to + 2 V, will read
correctly in the meter without any further calibration�

SPAN RANGE Header
When this header is provided it works in conjunc-
tion with the SPAN ADJUST Header by splitting its
adjustment range into a Hi and a Lo range. This
has the effect of dividing the adjustment range of
the SPAN pot into ten equal 10% steps across
100% of the input Signal Span�

SPAN ADJUST Header
This unique five-position header expands the adjust-
ment range of the SPAN pot into five equal 20% steps,
across 100% of the input Signal Span� Any input Signal
Span can then be precisely scaled down to provide any
required Digital Display span from 1999 counts to 001
(one count)�

ZERO Potentiometer (Pot)
If provided, the ZERO pot is always to the left
of the SPAN pot (as viewed from the rear of the
meter)� Typically it enables the input signal to be
offset ±5% of full scale (-100 to +100 counts)�
Input Module Component Glossary
ZERO ADJUST Header
When this header is provided, it works in conjunc-
tion with the ZERO OFFSET RANGE Header,
and expands the ZERO pot’s offset capability into
five equal negative steps or five equal positive
steps� This enables virtually any degree of input
signal offset required to display any desired engi-
neering unit of measure�
ZERO OFFSET RANGE Header
When provided, this three position header
increases the ZERO pot’s capability to offset the
input signal, to ±25% of the digital display span�
For example a Negative offset enables a 1 to 5V
input to display 0 to full scale� The user can select
negative offset, positive offset, or no offset (ZERO
pot disabled for two step non-interactive span and
offset calibration)�

Installation Guidelines
Installation
1� Install and wire meter per local applicable codes/reg-
ulations, the particular application, and good installation
practices�
2. Install meter in a location that does not exceed the
maximum operating temperature and that provides
good air circulation�
3. Separate input/output leads from power lines to
protect the meter from external noise. Input/output
leads should be routed as far away as possible from
contactors, control relays, transformers and other noisy
components� Shielding cables for input/output leads is
recommended with shield connection to earth ground
near the meter preferred�
4. A circuit breaker or disconnect switch is required to
disconnect power to the meter� The breaker/switch
should be in close proximity to the meter and marked as
the disconnecting device for the meter or meter circuit�
The circuit breaker or wall switch must be rated for the
applied voltage (e�g�, 120VAC or 240VAC) and current
appropriate for the electrical application (e�g�, 15A or
20A)�
5� See Case Dimensions section for panel cutout infor-
mation�
6� See Connector Pinouts section for wiring�
7. Use 28-12 AWG wiring, minimum 90˚C (HH) tem-
perature rating. Strip wire approximately 0.3 in. (7-8
mm)�
8. Recommended torque on all terminal plug screws is
4�5 lb-in (0�51 N-m)�
