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.

### Software Logic Tree

The BL-40PSF is an intelligent meter with a hierarchical 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 indicating the input signal.

15 Second Program Timeout The meter has a 5 second program timeout. If no buttons are pressed for 5 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.

### Digital Rescaling

The DL-40PSF 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 -999 to +9999. The default value of the Offset is 0

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 -999 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 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 meters digital Scale Factor is set to

2000 and Offset set to 0 then, any pre-calibrated signal conditioner with an output that does not exceed V to + 2 V, will read correctly in the meter without any further calibration.

I-Series Input Signal Conditioning Modules Many additional input modules are available and others are constantly being developed. Check with your local distributor or www.texmate. com for updated information.

Pre-calibrated I-Series input modules, that have span or zero potentiometers, can be interchanged between any I-Series compatible meter, without recalibration, because all of the analog scaling and reference circuitry is self-contained within the module. Where appropriate, all the standard ranges shown are designed to be header selectable by the user, and Texmate's unique SPAN ADJUST Header facilitates scaling to almost any required engineering unit. See Input Module Component Glossary and Calibration on pages 3 and 4. Also see Two Point Digital Calibration and Digital Calibration on page 4.

Unless otherwise specified Texmate will ship all modules pre-calibrated with factory preselected ranges and/or scalings as shown in BOLD type. Other pre-calibrated standard ranges or custom ranges may be ordered. Factory installed custom scaling and other custom options are also available (see Ordering Information, Special Options on last page).

### Input Module Component Glossary

Input and Output Pins On most modules Pin is the Signal High input and Pin 3 is the Signal Low input. Typically Pin 2 is used for Excitation Voltage output.

24V DC Output Header On some modules this header enables a 24V DC 25mA (max) Excitation/Auxiliary output to be connected to Pin 2.

INPUT RANGE Header

Range values are marked on the PCB. Typically two to four positions are provided, which are selected with either a single or multiple jumper clip. When provided, a custom range position is only functional when the option has been factory installed.

SPAN Potentiometer (Pot)

If provided, the 5 turn SPAN pot is always on the right side (as viewed from the rear of the meter).

Typical adjustment is 20% of the input signal range.

SPAN ADJUST Header

This unique five-position header expands the adjustment range of the SPAN pot into five equal 20% steps, across 00% of the input Signal Span. Any input Signal Span can then be precisely scaled down to provide any required Digital Display span from 999 counts to 00 (one count).

SPAN RANGE Header

When this header is provided it works in conjunction 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 0% steps across 00% of the input Signal Span.

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 (-00 to +00 counts).

ZERO OFFSET RANGE Header When provided, this three position header increases the ZERO pots capability to offset the input signal, to 25% of the digital display span.

For example a Negative offset enables a 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).

### ZERO ADJUST Header

When this header is provided, it works in conjunction with the ZERO OFFSET RANGE Header, and expands the ZERO pots 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 engineering unit of measure.

### Input Module Analog Calibration

In addition to the analog calibration capabilities that enable many modules to be interchanged between different meters without loss of accuracy the Leopard Family of meters have enhanced Digital Calibration functions. See Page 4

Basic standard range calibration of direct reading modules that utilize either Auto Zero or a ZERO pot, an INPUT RANGE Header and or a SPAN pot.

If the module has an INPUT RANGE Header, reposition the

jumper clip to select the desired input signal range.

2. Apply a zero input or short the input pins. The display will auto zero, or if the module has a ZERO pot, it should be adjusted until the display reads zero.

3 Apply a known input signal that is at least 20% of the full scale input range and adjust the SPAN pot until the display reads the exact input value. For negative inputs, Leopard Family Meters will display negative overrange at 50% of full scale range.

4 Decimal Points. The selection or positioning of decimal points

has no effect on the calibration of the modules

Wide range scaling, in engineering units not requiring offsets, with modules that utilize auto-zero or a ZERO pot, a SPAN RANGE Header and or a SPAN ADJUST Header.

Texmates unique SPAN ADJUST and SPAN RANGE Headers provide the circuit equivalent of an ultra-precision one megohm 75 or 50 turn potentiometer that can infinitely scale down any Input Signal SPAN to provide any full scale Digital Display Span from 999 (counts) to 00 (one count).

If the module has an INPUT RANGE Header, and the required full

### Input Module Calibration Procedures Continued

scale Digital Display Span (counts) is to be larger than the directly measured value of the input Signal Span, then the next lower range on the INPUT RANGE Header should be selected. The resulting over range Signal Span is then scaled down, by selecting the position of the SPAN RANGE Header and or the SPAN ADJUST Header, which will reduce the input Signal Span to a percentage, that the required Digital Display Span can be reached by calibration with the SPAN pot.

Example A: 0 to 0 V to read 0 to 800 gallons.

Signal Span = 0V, Digital Display Span = 800 counts

Select the 2 V INPUT RANGE Header position. This will provide a digital display of 800 counts with an input of only .8 V which is (.80)=8% of the examples 0 V Signal Span.

2 To scale down the Signal Span to 8% select the 20% Signal Span position on the SPAN ADJUST Header (position ) or if the module has a SPAN RANGE Header, select (LO Range) and 20% Signal Span position on the SPAN ADJUST Header (position 2).

3 Apply a zero input or short the input pins. The display will auto zero, or if the module has a ZERO pot, it should be adjusted until the display reads zero.

4 Apply 0 V and adjust the SPAN pot until the display reads

800.

Large offset scaling and calibration of process signal inputs with modules that utilize ZERO ADJUST Headers and or ZERO OFFSET RANGE Headers.

Texmates unique ZERO OFFSET RANGE Header enables the use of a simple two step scaling and calibration procedure for those process signals that require large offsets. This eliminates the back and forth interaction, between zero and span settings, that is often required to calibrate less finely engineered products.

The first step is to set the ZERO OFFSET RANGE Header to the center position (No Offset) and scale down the Input Signal Span to a percentage that will enable calibration with the SPAN pot to reach the required Digital Display Span.

The second step is to set the ZERO ADJUST and or ZERO OFFSET RANGE Header to provide a positive or negative offset of sufficient counts that calibration with the ZERO pot will offset the Digital Display Span to produce the required digital reading.

### Case Dimensions

Example B: to 5 V to read 00 to 500 C.

Signal Span = 4V, Digital Display Span = 600 counts

If the module has an INPUT RANGE Header the 2 V position should be selected. This will provide a digital display of 600 counts for an input of .6 V which is (.6 4) = 40% of the examples 4 V signal span. To scale down the Signal Span to 40% select the 40% Signal Span position on the SPAN ADJUST Header (position 2).

2 If the module is a Process Input -5 V DC type, select the (Hi Range) position on the SPAN RANGE Header and the 00% Signal Span position on the SPAN ADJUST Header (position 5, max increase).

This will provide a digital display of 600 counts for an input of 4V which is 00% of the examples 4V Signal Span.

3 Set the ZERO OFFSET RANGE Header to the center position (no offset). Apply V and adjust the SPAN pot until the display reads 400. A 4V input would then read 600 counts.

4 Set the ZERO OFFSET RANGE Header to the negative offset position. If the module has a ZERO ADJUST Header select the position that will provide a negative offset of 500 counts.

Apply V and adjust the ZERO pot until the display reads 00. Apply 5 V and check that the display reads 500.

Example C: 4 to 20 mA to read 00.0 to +00.0% Signal Span = 6 mA, Digital Display Span = 000 counts.

The full scale Signal Span of the Process Input 4-20 mA modules is 0 to 20 mA for a full scale Digital Display Span of 0 to 2000 counts. This will provide a digital display of 000 counts with an input of only 0 mA which is (06)=62.5% of the examples 6 mA signal span.

2 To scale down the Signal Span to 62.5% select the (Hi Range) Position on the Span Range Header and the 70% Signal Span position on the SPAN ADJUST Header (position 2).

3 Set the ZERO OFFSET RANGE Header to the center position (no offset). Apply 4 mA and adjust the SPAN pot until the display reads 250. A 6 mA input would then read 000 counts.

4 Set the ZERO OFFSET RANGE Header to the positive offset position. If the module has a ZERO ADJUST Header select the position that will provide a negative offset of 250 counts.

Apply 4 mA and adjust the ZERO pot until the display reads 000.

Apply 20 mA and check that the display reads 000. Select decimal point XXXX to display 00.0 to 00.0.
