### Manual Rescaling Mode

When the rear Auto/Manual switch is in the Manual position, the meter can be rescaled without applying an external signal by changing the oFSt (offset) and SCAL (scale) parameters in the user menu. A pre-calibrated Input Signal Conditioning module must be used. The meter assumes that this calibration used a true zero input (0V from conditioner to meter) resulting in a display value of 0 and a maximum input signal span (2V from conditioner to meter) resulting in a display value of the SCAL value set in the user menu. The linear equation is y = mx + b where m = (SCAL-0)/(2-0) and b = oFSt.

The default value of SCAL is 2000, but it may be set to any value between -1999 and +9999.

The internal Signal Span is limited to 3 V DC between1 V DC to+ 2 V DC. Any outputs from an Input Signal Conditioning module that exceed these limits will cause the meter to indicate overrange regardless of the Digital Display Span scaled. For example, an ID01 DC Volts Input Signal Conditioner can read +/-2VDC, but in the DL-40 will show under-range for a -1.2V input.

The Digital Calibration Procedure Mode is Now Complete.

The menu branches to the DECIMAL POINT AND BRIGHTNESS SE LECTION, (see page6) and the display flashes [dP] and the previous decimal point selection.

### Auto Calibration Mode

When the rear Auto/Manual switch is in the Auto position, the meter can be calibrated with an automatic scale factor calculation, by applying a low input signal (InLo), entering the desired low display reading for that signal (ZERO), then applying a high input signal (InHi), and then entering the desired high display reading (SPAN). The meter then automatically calculates and programs in the requisite scale factor using a true linear (y=mx + b) calculation where m = (SPAN-ZERO)/(InHi-InLo) and b = ZERO, but within the following parameters.

1. Positive and negative signals may be applied, but the difference between the high and the low signal inputs must be at least 1000 counts or Err will be indicated.

2. Positive and Negative values for the desired reading can be entered, but the scale factor created can not exceed the Digital Display Span capability of the meter which is 12,000 counts between 1999 to 9999.

3. The internal Signal Span is limited to 3 V DC between 1 V DC to + 2 V DC. Any outputs from an Input Signal Conditioning module that exceed these limits will cause the meter to indicate overrange regardless of the Digital Display Span scaled.

Note: Most input signal conditioners have provisions for analog calibration and scaling. If the meters digital scale factor is set to read zero with a zero input (shorted input), and to read 1000 with a 1.000 V input, 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.

If the digital calibration was successfully completed, the menu branches to the DISPLAY FUNCTION CONFIGURATION MODE, (see page 7) and the display flashes [dP] and the previous setting.

ERROR

Indicates Unsuccessful Calibration

If the calibration was unsuccessful, the display indicates [Err], the new calibration settings just entered will not take effect and the previously stored setting will remain.

The three most likely causes of an error during calibration are:

1) The full scale and zero signals were too similar. The full scale signal must be at least 1000 counts greater than the zero or low input signal (positive and negative values are allowed).

2) The scaling requirement exceeded the capability of the meter

(1999 to 9999).

3) No input signal present, or incorrect connections.

### Modbus RTU & RS-485 Communication Settings

The Modbus/RS-485 communication settings sub-menu allows you to set the following parameters:

a) Baud Rate this is the baud rate of the RS-485 serial communication between the meter (slave) and Modbus master. Options are

9600 (default, meter shows 96) and 19200 (meter shows 192).

b) Address this is the meters Modbus address on the RS-485 loop. Typically, RS-485 limits the number of devices on the loop to 32, but the DL-40 supports the full Modbus address range of 1-247.

Address 1 is the default value.

c) Parity this is the parity setting for the RS-485 serial communication between the meter (slave) and Modbus master. Options are: None (display shows 0; Odd (display shows 1); Even (default, display shows 2).

The meters response time to a read command from the master is 40-45msec (typically 42msec). The response time for a write command is 70-75msec (typically 72msec). This is due to the module having to communicate to the meters core firmware to complete the desired command. Exception responses are handled directly by the module and typically have a response time of 3msec.

### Modbus RTU Implementation

The DL-40 Modbus communication module supports the following

Modbus commands:

a) Read Holding Register (0x03)

b) Write Single Register (0x06)

Modbus addresses for DL-40JANUS registers are shown on

the next page

The following are some things to note about particular registers:

a) Modicon address 40001 RELAY has the bit values for Sp3 & Sp4 and LED3 & LED4 reversed. There is an historical reason for this, and we have chosen to maintain backward compatibility in case customers want to send their meters in for a Modbus upgrade (at a nominal fee).

b) Modicon addresses 40002 INP, 40026 PEAK, 40027 VALY,

40029 ZERO, 40029 SPAN return a 2 byte hexadecimal value of the meters display (in counts) and does not include the decimal point. If you need the decimal value with decimal point, you will need to read the register, convert it to decimal, read 40024 (see below) to determine decimal location, then combine the two. Display counts are in Twos Complement notation.

a. Hex values for 0 to 9999 are 0x0000 to 0x270F.

b. Hex values for -1 to -1999 are 0xFFFF to 0xF831.

c. Over-range is indicated by a returned value of 9999 (0x270F).

d. Under-range is indicated by a returned value of -1999 (0xF831).

c) In order for Sp3 and Sp4 set point settings to work, the DL-40 must have the optional Output Carrier Board installed (P/N SA-DL/OM-CB).

d) All Delay on Make (DoM), Delay on Break (DoB) and Hysteresis

values are in units of whole seconds.

e) Modicon address 40023 RLYMOD uses the following values to set the relay activation mode (letter sequence is SP1, SP2, SP3, SP4):

a. 0 for HHHH

b. 1 for HLHL

c. 2 for LHLH

d. 3 for LLLL

e. H means relay is energized if input is equal to or

exceeds setpoint; L means relay is energized if input

is less than setpoint.

f. Note that the meter will not show the last two letters if

the Output Carrier Board option is not installed.

f) Modicon address 40023 DP uses the following values to set the

display decimal point location:

a. 0 for XXXX (none)

b. 1 for XXXX.

c. 2 for XXX.X

d. 3 for XX.XX

e. 4 for X.XXX

g) Modicon address 40025 BRIGHT must be a value between 1

(most dim) to 4 (most bright).

h) Modicon addresses 40028 and 40029 will have different meanings depending on the Auto calibration or Manual rescaling operational selection (see Auto Calibration Mode or Manual Rescaling Mode above). These are explained in the register table below.

i) Modicon addresses 40030 IZERO and 40031 ISPAN return hexadecimal values related to the Auto Mode calibration of the meter. They do not necessarily match expected values due variations and tolerances in the measurement circuit components, e.g., calibrating with a value of zero volts for the ZERO value may return a value of 0xFFFE (-2). These registers have no meaning in Manual Rescaling Mode).

### Setpoint Setting and Relay Configuration Mode

The following programming steps are required to enter the setpoint values and configure the relay functions in a meter with four relays using four setpoints. Generally if less than four relays are installed the software auto detects missing relays and deletes reference to them from the menu. In some cases setpoints without relays are operational for display only purposes.

### Installation Guidelines

## Installation

1. Install and wire meter per local applicable codes/regulations, 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 information.

6. See Connector Pinouts section for wiring.

7. Use 28-12 AWG wiring, minimum 90 C (HH) temperature 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).

### 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

Symbols Indicate Module Compatibility Within Meter Families

SPAN ADJUST Header facilitates scaling to almost any required engineering unit. See Input Module Component Glossary and Calibration on pages 14 and 15. Also see Manual Rescaling on page 4 and Auto Calibration on page 5.

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 1 is the Signal High input and Pin 3 is the Signal Low input. Typically Pin 2 is used for Excitation Voltage output.

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.

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

SPAN Potentiometer (Pot)

If provided, the 15 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.

### Input Module Component Glossary Continue

SPAN ADJUST Header

This unique five-position header expands the adjustment 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 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 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).

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 10% steps across 100% 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 (-100 to +100 counts).

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 4-5.

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.

1 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 150 turn potentiometer that can infinitely scale down any Input Signal SPAN to provide any full scale Digital Display Span from

1999 (counts) to 001 (one count).

Page 15

### Input Module Calibration Procedures Continued

If the module has an INPUT RANGE Header, and the required full 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 10 V to read 0 to 1800 gallons.

Signal Span = 10V, Digital Display Span = 1800 counts

1 Select the 2 V INPUT RANGE Header position. This will provide a digital display of 1800 counts with an input of only 1.8 V which is (1.810)=18% of the examples 10 V Signal Span.

2 To scale down the Signal Span to 18% select the 20% Signal Span position on the SPAN ADJUST Header (position 1) 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 10 V and adjust the SPAN pot until the display reads 1800.

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.

Example B: 1 to 5 V to read 100 to 1500 C.

Signal Span = 4V, Digital Display Span = 1600 counts

1 If the module has an INPUT RANGE Header the 2 V position should be selected. This will provide a digital display of 1600 counts for an input of 1.6 V which is (1.6 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 1-5 V DC type, select the (Hi Range) position on the SPAN RANGE Header and the 100% Signal Span position on the SPAN ADJUST Header (position 5, max increase).

This will provide a digital display of 1600 counts for an input of 4V which is 100% of the examples 4V Signal Span.

3 Set the ZERO OFFSET RANGE Header to the center position (no offset). Apply 1 V and adjust the SPAN pot until the display reads 400. A 4V input would then read 1600 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 1 V and adjust the ZERO pot until the display reads 100. Apply 5 V and check that the display reads 1500.

Example C: 4 to 20 mA to read 00.0 to +100.0% Signal Span = 16 mA, Digital Display Span = 1000 counts.

1 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 1000 counts with an input of only 10 mA which is (1016)=62.5% of the examples 16 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 16 mA input would then read 1000 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 1000. Select decimal point XXXX to display 00.0 to 100.0.

The clear lockable cover is designed to be dust and water proof to NEMA-4X, IP65 standards. The assembly consists of a base and cover with a cam hinge and key-lock fastening mechanism. An O-ring, or neoprene gasket forms a seal between the base and the panel. The cam hinge prevents the cover from closing when opened until pushed closed. The cover has a tapered recess that, when closed, forms a seal with a tapered spigot on the base. A key-lock employs a cam locking device to force the spigot into the recess, ensuring seal integrity. A safety catch keeps the cover closed even when the key is removed, and the keyhole can be used to attach a safety seal clip, preventing unauthorized opening.

### & Mounting Clips

The meters plastic case is made from fire retardant polycarbonate. A metal surround case can be ordered to enhance the meters fire retardant capabilities and also provide shielding against electromagnetic interference (EMI). The metal case slides over the polycarbonate case and is held firmly in place by spring-type non-return clips. The Metal Surround Case must be factory installed on the polycarbonate case and once installed, it cannot be removed in the field.

With the metal case in place, the meters standard ratchet-type mounting clips can not be used. Instead a pair of screw-type DIN standard mounting clips are provided, which clip into holes on the side of the metal case and tighten against the rear of the panel. A ground tab on the metal case enables the metal case to be easily connected to the panel ground.
