2.5 Connection to the Load Cell

The load cell 1 terminal board of the LaserLT-60 and LaserLT-100 must be connected to the 6-wire load cell; if using a 4-wire load in the load cell 1 terminal board, cell excitation must jumper to sense, see Figure 2-2. Load cells 2, 3, and 4 must be connected to 4-wire load cells, see Figure 2-3.

Sense is always enabled and, when not using 6-wire load cell, the sense terminals must be jumpered to the same polarity excitation wires.

Sense compensates for drops in voltage along the cable that connects the instrument to the load cell. Voltage is lost when the instrument and the load cell are greater than 30 ft apart. A cable is typically provided with a load cell. When exceeding the length of the provided load cell cable, six wires must be used to compensate for voltage drop. It is recommended to never cut or shorten the load cell cable.

3.11.2 Alibi Memory

The alibi memory allows for transmitted weight values to be filed in the PC for data processing and/or integration. The filed values can then be recalled from the PC serial line or directly on the instrument’s display for a following check.

Storage of a weight value occurs following the reception of the serial command or by pressing . The instrument transmits

the gross and tare weights and an ID on the serial port. The ID has the format: <Rewriting number>-<Weigh number>

• The rewriting number is a five digit number from 00000-00255; It indicates the number of complete rewritings of the alibi memory

• Weigh number is a six digit number from 000000-131072; It indicates the weigh number in the current rewriting of the alibi memory; The weigh number is increased by 000001 with each weigh storage; Once the value reaches 131072, it restarts from 000000

The storage of a weigh value occurs only if the gross weight is greater than or equal to zero, it is stable and valid (not in under-load or overload). Depending on how F.ModE rE A C t has been configured in the technical set up, the storage of a weight by pressing a key is possible only if the condition is met (weight exceeds zero, weight instability or always).

4.4.1 Filter Parameters

Standard digital filtering uses mathematical averaging to compensate for the noise that the A/D converter sends periodically because of external vibration. This filter compensation makes data less susceptible to a DC signal bias error for some signals.

Each of the filters of the LaserLT are intended to compensate for different types and intensities of digital noise and vibration. Below, find general usage for each family of filters and the A/D Rate and Window for each filter within those families:

Weight error caused by a different gravitational value between calibration zone and zone of use is automatically corrected.

Press and hold when turning on the instrument. The g value relative to the gravitation zone of the user displays for a few

seconds, after the name and the installed software version.

To find the local gravity, enter the latitude and elevation into the International Gravity Formula.

Listed are links to websites that can be used to determine local latitude and altitude. Please note these website address are provided for reference only and may change.

Map Coordinates uses Google maps to find latitude and elevation: www.mapcoordinates.net/

Once local latitude and altitude have been determined, use the following link to calculate local gravity

6.0 Communications

This section provides an overview of LaserLT-60 and LaserLT-100 Weight Indicator communication information.

6.1 Serial Outputs

The instrument has two bidirectional serial outputs which are ASCII code compatible with most printers, remote displays, PCs and other devices. See Section 2.4 on page 5 for connection information.

Transmission of data through the serial ports can be configured in the parameters PC SEL, PCModE and Pr.ModE in the setup mode (Section 6.2 on page 41).

6.1.1 COM1 Serial Port

The COM1 serial port is bi-directional (half duplex) and uses RS-485 for transmitting data. It is mainly used to connect PCs, PLCs and additional remote displays. The transmission speed may be selected in the setup as: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 baud (bit/sec).

On the same RS-485 line, it is possible to connect up to 32 devices (instruments, RS-485/RS-232 signal converter). Considerations when making RS-485 connections:

• Use a Shielded Twisted Pair cable to make the connection (twisted and shielded pair(s) with single shielding for each pair through aluminum band and total shielding through external shielding)

• Using 2x24 AWG duplex cable with external shielding, the RS-485 cable should not exceed 4000' (1200 m) (Section 8.0

on page 53)

• With very long cables, cable capacity becomes a dominant factor in power consumption (normally near 50pF/m); Cable capacity decreases as length increases; Capacity also decreases when speed is increased; The maximum distance cannot be covered with the maximum possible speed

Baud Rate (bit/sec) Total Cable Capacity (pF)

1200 400000 2400 200000 4800 100000

9600 50000 19200 25000 38400 12000 57600 8000

115200 4000

Table 6-1. Cable Capacity

• Verify single point grounding on all equipment (Section 2.3 on page 4)

• Use correct single point grounding to avoid forming ground loops

• On the RS-485 network, two termination resistances equal to the impedance of the cable (typically 120 Ω) are normally connected on the two devices at the ends of the cable; Terminal resistance is not supplied with the ports of the instrument

• Consult the device product data sheet for all connected devices to ensure consistency in the markings

6.1.2 COM2 Serial Port

The COM2 serial port is bi-directional (full duplex) and uses an RS-232 for transmitting data. It is mainly used to connect printers, PCs, and PLCs. The transmission speed may be selected in the setup as: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 baud.

PrPC.St allows for transmission of the standard string by pressing Enter (Section 6.4.1 on page 49)

Transmission when is pressed – The instrument transmits the weight data through the serial port

when is pressed; Transmission takes place if the weight is stable and the net weight is > 20 divisions;

Re-enabling the transmission depends on how rEACt is set in the setup mode (passing by zero of the net weight, weight instability or always); Data is transmitted with the standard string Prin.St or the extended string; See Section 6.4 on page 49 for a description of the strings; The transmission is confirmed when trAnSM displays

Continuous Transmission for interfacing to the PC, remote displays and other devices which request a constant stream of the data independently from the weight stability; The instrument transmits data with each A/D cycle:

• Baud rate at 9600 up to 10 transmissions per second are possible

• Baud rate at 115200 up to 16 transmissions per second are possible for the PC port and up to 12 for the printer port

The data transmits both positive and negative values:

• ALL.Std – The data is transmitted using the standard string

• ALL.EXt – The data is transmitted using the extended string (or multi-scale string in the TRANSM mode)

Transmission on stability – each time a weight on the scale becomes stable, a communication string is transmitted on the PC port;

• The transmission takes place when weight is stable and the net weight is greater than 10 display divisions

• Re-enabling the transmission depends how rEACt has been set in the setup mode (Table 4-3 on page 21)

• The data is transmitted with the standard string StAb.St or the extended string StAb.EX (or multi-scale string in the TRANSM mode); See Section 6.4 on page 49 for a description of the three strings

mitting data (Section 6.3 on page 44) With baud rate at 9600, up to 10-11 requests per second are possible through the READ command; with baud rate at 115200, up to 16 requests per second are possible through the READ command; The data transmits both positive and negative values

The weight display occurs both in the instrument and is transmitted to a 6 digit remote display

The instrument communicates the weight data through the serial port when is pressed:

• Transmission takes place if the weight is stable and the net weight is > 20 divisions; re-enabling transmission depends on how the rEACt is set in the setup mode (passing by zero of the NET weight, weight instability or always)

• Prin.St - The data is transmitted using the standard string

• Prin.EX - The data is transmitted using the extended string

- See Section 6.4 on page 49 for a description of the strings

• The transmission is confirmed when trAnSM displays

if its ID is the one requested (before the request the module ID must be input, i.e. 00READ<CRLF>); If a broadcast address command (99) is received no answer is given; If the command is correct it is executed
