Installation

This section provides an overview of LaserLT-60 and LaserLT-100 installation.

Install the instrument on a stable, vibration free, flat surface. Disconnect from power source to completely power off the instrument. The back mounting bracket is for vertical mounting. An optional side mount for horizontal surfaces is available for the LaserLT-100.

Remove protective film from the overlay as it may become difficult to remove if exposed to heat or sunlight.

Grounding the System

For proper grounding and optimal functioning of the system, it is necessary to create a single point ground in proximity of the instrument on which to connect the ground of the instrument, an interface cable and shields. Connect the ground point of the remote display directly to the ground bar of the electric panel or to a grounding rod.

Wiring Schematic

For proper device wiring, refer to the schematic below:
Figure 2-1. Wiring Schematic

Pins 3 – 12 and 18 – 35 are not used for remote display models
Table 2-1. Remote Display Connections

Power Supply

The instrument is supplied with an AC power cord, connected to an internal AC/DC power adapter. To power the instrument with 12 VDC or 24 VDC, connect the power supply cable directly to the terminal strip on the CPU board, see J1 in Figure 2-1. This input is for static DC, not for an automotive source.

The maximum power of the outputs 48 VAC 0.15A max (or 60 VDC 0.15 A max), the maximum voltage applicable to the inputs is between 12 VDC and 24 VDC with current from minimum 5 mA to maximum 20 mA.

Configuration

This section provides an overview of LaserLT-60 and LaserLT-100 configuration.

Manual Configuration Using W.rEPE

W.rEPE is a configurable mode that allows identification and location of data within the string. The W. rE PE parameter is selected, it allows for the manual configuration of parameters to parse string data. The manual configuration is defaulted to read the Rice Lake continuous format.The Rice Lake continuous format is defined as:
Figure 3-3. STR-1 Rice Lake Stream Data Format

Figure 3-4. String Configuration Parameters

Table 3-3. String Configuration Parameter Definitions

in ASCII code; Default value is 10 = LF
Ei.PoS| Weigh Position – Identifies the 1st character position of the weight in the string; 1st string character has index zero; Default value is 01, see Figure 3-5 on page 8
Ei.LEn| Weigh Length – Identifies number of characters of the weight data string; Default value is 08 (polarity and seven weight digits)
Str.LEn| String Length – Identifies the length of the string transmitted from the indicator; Enter a value from 0–3; Default value is 13
dECi| Decimal –Enter a number of scale decimals from 0-5for FIXED; Default value is STREM
unit| Unit –Identifies unit of measure; available units are G, Lb, t, KG; Default unit of measure is Lbbut not available for incoming data
Stb| Stability – Identifies number of readings used to compare for stability; Default value is 3
St.int| Stability Intensity – Identifies weight difference for the stability sample between reading to identify motion; Default value is 2
trShLd| Threshold – Identifies minimum and maximum capacity for display blanking
dU.CEd| Advanced – See Section 3.3.2 on page 8 for advanced settings information
req. ei| Not applicable
rEM.KEy| Remember Key – Settings: K.Zero, K.tre, K.ModE,K.Print;

Allows for the command to be sent to the indicator when the relative function key is pressed;

Up to 12 characters can be defined for the string if the first character is ASCII 0 the remote key is disabled; Function key defaults are:

• ZERO = KZERO
• TARE = KTARE
• MODE = KGROSSNET
• PRINT = KPRINT

The following parameters must be set when working in W.rE PE:

• W ei.P os
• W ei.L en
• A dv.C ed

String Example

The weight value of the first character position is defined within the parameter of weight position, or W ei. pos, in the string transmitted by indicator. A possible polarity sign is also part of the weight value. The unit can parse a string up to 39 characters. For example, if the received string is bpwwwwwwwLGS+CR+LF:
Figure 3-5. Rice Lake Continuous Data Format Example

Advanced Parsing Parameters

Advanced Parsing Parameters utilize logical operators and bit masking to set the individual bits of the string to read the sign, stability, zero and over/under load and units.
Figure 3-6. Advanced Configuration Parameters

Table 3-4. Advanced Parsing Parameter Settings

positive or negative
StbiL| Stability – Bit and character that indicates if the weight is stable
.ZEro| Weight Zero – If the value is not set (MASK = 0) the scale is considered to be in the zero range when the weight is equal to 0
.UnDeR.L| Weight Under Load – Bit and character that indicates if the weight is under load
oUEr.L| Over Load – Bit and character that indicates if the weight is over load
Unit| Unit 1 – Lights W1; If 076 lights unit 1, the unit of measure is L, or pounds;

Unit of measurement stickers are provided to replace W1 function LED labels

Unit2| Unit 2 – Lights W2; If 075 lights unit 2, the unit of measure is K, or kilograms;

Unit of measurement stickers are provided to replace W2 function LED labels

Each of the Advanced parameters are defined by setting the following parameters:
Table 3-5. Advanced Parsing Parameter Settings

dU.CEd(from 0–255); Character is logical   dv.Cedwith this mask,

the result is compared with Value; Parameter is not managed if the value is set to 0

n.byte| Index Byte – Indicates the character where the data will be extracted; Character index in the string
vlue| Value – Character value that defines what was selected in   dU.CEdstep; If the character of the string is a letter it is necessary to insert the

relative ASCII code value Und.Ourif the tr.L0is set and the tr.HIparameters will be ignored

Example: If the string sent by the scale indicator has the form: WWWWWWF Where WWWWWW is the weight, F some flags.

Wei.pos will be 0. Wei.Len 6.
If check bit 2 of flag character F is desired and this bit is about negative weight, then set in A dv.ce d / Ne g.sig:

• Mask = 4 (if check bit 2 is desired, binary mask is 00000100, decimal = 4)
• N.Byte = 6
• Value = 4

When character 6 of the string AND (logical AND) Mask = 4 weight is considered negative.

Check Multiple Bits

Sum the mask decimals of all bits to be checked to check multiple bits.
Example: Check bits 7 (decimal 64) and 6 (decimal 128) the mask will be 192 (binary 11000000).

Sum all mask decimals to check a whole character.

Example: If the stability condition is a character ‘S’ in a certain position, the mask will be 255 (11111111 binary) and value will be 83 (ASCII code of character S). When character and 255 (character remains unchanged) is equal to ASCII of S (83) the weight is considered stable.

An example for standard string parameters of the Rice Lake continuous format:
Figure 3-7. STR-1 Rice Lake Stream Data Format

Semi Auto Learn Using rEPE.in

rEPE .in is a semi-automatic mode to establish the start and end positions of the weight value. rEPE . in has no parameters and does not read annunciators for units, mode, or status. This parameter is in the PC Mode.

The polarity sign is to be included as part of the start position. The total weight length can be more than six characters. If anegative value is present, the negative sign will be placed in the character to the left of the displayed value, as long as the value is not more than five digits.

If the weight value includes leading zeros they will be displayed. Navigate parameters for the configuration of the weight indicator by using the display keys, see Table 1-2 on page 3 for navigation assistance:

1. Con. Ai displays, press  .
2. The detected baud rate and the milliseconds to read the string displays, press .
3. Verif y and the first recognized character displays, navigate parameter using the five function keys, press 
4. Set? displays, press .
5. Wait. . .. Start displays, wait for the process to finish.
6. The start of the string will display, navigate parameter using the five function keys, press 
7. End displays the end of the string, navigate parameter using the five function keys, press  .Baud, bits, address (for RS-485) and timeout can be configured or the learn mode can be saved.
