About This Manual This manual is intended for use by service technicians responsible for installing and servicing the LaserLight® LED remote display. Installation procedures are presented in the order likely to be followed by the installer: pre-installation setup, configuration, and on-site installation. 1.0 Caution Most procedures described in this manual require work inside the remote display enclosure. These procedures are to be performed by qualified service personnel only.
1.1 Annunciators The 7-segment LaserLight remote display uses a set of four high-intensity LED annunciators (shown in Figure 1-1) and the matrix display uses two positions of the display to show arrows (shown in Figure 1-2) which provide additional information about the value being displayed: • Gross and Net annunciators are lit to show whether the displayed weight is a gross or net weight.
2.0 Mounting Plate Installation and Setup The LaserLight remote display can be easily set up and configured once mounted to a wall or pole. This section describes basic installation, AC wiring, RS-232, RS-485, and 20 mA current loop connections. Once installation setup is complete, go to Section 3.0 for information on configuring the remote display. Caution Use a wrist strap to ground yourself and protect components from electrostatic discharge (ESD) when working inside the enclosure.
4. Disconnect the AC cord assembly from the power supply. 5. Using a slight diagonal twisting motion, slide the mounting plate out from the inside of the enclosure and set it aside. Figure 2-2. Tab Pin Assembly on Inside of Remote Display Enclosure 2.3 Wall Mounting The LaserLight remote display can be mounted to any vertical surface or pole. Select a site and use installation screws or wall anchors to secure the remote display to a wall.
2.4.1 AC Wiring The LaserLight power supply can run on either 115 or 230 VAC. The AC wiring is run through the cord grip to a 3-position AC terminal block bracket on the inside of the enclosure (shown in Figure 2-4). This bracket can be removed by loosening the two standoffs and lifting it off. It can then be lowered and pulled outside of the enclosure to ease wiring connections. Grounding stud Figure 2-4.
2.4.2 Serial Wiring Serial communications are connected to the CPU board using removable screw terminal plugs on J6, J8 and J9 (see Figure 2-8). To connect the communications cable to the remote display, do the following: 1. If the enclosure is not open, disconnect power and open the remote display by removing the captive screws on the bottom of the enclosure and lower the mounting plate. 2. Open the captive retaining screws (Figure 2-6) and flip forward the hinged mounting plate.

Figure 2-8 shows the LaserLight remote display CPU board.
2.4.6 Reset Switch The reset switch enables a simulated power up reset. It then goes back to normal operation mode. The reset switch eliminates having to unplug the unit to do a reset. Refer to Figure 2-8 on page 7 for the reset switch location on the CPU board. 2.4.7 Communicating with Indicators and LEDs Small LEDs located on the CPU board flash when serial data is received or sent. The transmit indicators flash when data is being sent out of the port.
3.0 Configuration Once the LaserLight remote display is installed, it may need to be configured if your indicator requires special settings. This can be done manually and is explained in Section 3.2. Using Auto-Learn (Section 3.1) simplifies installation by automatically detecting the communications format and data rate used by the indicator and eliminates the need for configuration. 3.1 Auto-Learn The LaserLight remote display incorporates a software feature called Auto-Learn.
The setup button is located on the secondary display board (Figure 3-2). Jumper position for decimal point or comma Setup button Figure 3-2. Setup Button Location on Secondary Display Board (7-Segment Display) The display board is mounted on a hinged mounting plate to allow for easy access to the CPU board. Press the SETUP button (shown in Figure 3-2) to access main menu configuration parameters.
Table 3-1 summarizes the functions of each of the main menus and Figure 3-4 illustrates the main menu selections. 7-segment Display Menu 8-Character Matrix Display Menu 12-Character Matrix Display Menu CONFIG CONFIG CONFIG Configuration.

3.4 Testing the Remote Display The LaserLight remote display provides a test to check the hardware of the remote display. These tests can be accessed through the main menu (Figure 3-7).

Test Menu Choices 3.4.1 Display When this feature is enabled, all LEDs remain lit until the ENTER button is pressed (Figure 3-2 on page 11). 3.4.
3.4.4 Loop Back When enabled, this feature provides a loop-back self test for use in diagnosing serial communications errors. The loop-back self test checks the function of the remote display serial port by sending and receiving data to itself. The following table shows the required connections.
The remote display also accepts serial commands to return the current time and date or to set the time and date to a new setting. This information can be used in conjunction with user programs in the 920i to ensure the indicator and remote display have the same time and date settings.

4.0 Options There are several options available with the LaserLight remote display. They include: • Time and date • Temperature NOTE: The Time-Date and Temperature options display in three-second cycles (along with weight) when displayed weight is zero or below. • Field installable visor • Pole mount kit • Traffic light option 4.1 Time and Date The time and date option can be either factory installed or can be ordered at a later date. Figure 4-1 shows the location of the time and date option.
4.4 Pole Mount Kit The LaserLight remote display can easily be mounted on a pole or steel I-beam using the optional pole mounting kit (PN 75856 - 4"), (PN 77775 - 6"), (PN 85343 - 8-character), (PN 85344 - 12-character). Use the following steps to install the pole mount option. 1. Use the enclosed 3/8" cap screws, washers ad lock nuts from the parts kit to attach the clinching pole brackets to the pole mounting weldment.

4.5 Traffic Light Option The Laserlight 4-SG remote display also comes with a traffic light option which uses 4" display digits in the 6" enclosure. The traffic light is factory configured to be controlled with serial commands (as described in Section 3.7 on page 20), but can be controlled by using dry contact switches: one switch, or two switches.
4.5.2 Single Switch Wiring If a single switch is used for controlling the traffic light, the user must select which two states (out of the four possible), they wish to see. 4.5.3 Two Switch Wiring If two switches are used for controlling the traffic light it is possible for the user to obtain any or all combinations of the four possible states.
5.0 5.1 Appendix Error Messages The LaserLight remote display provides several error messages. When an error occurs, the message is shown on the display. NOTE: Some of the actual error messages displayed by the remote display are cryptic and are represented in Table 5-1 as closely as possible with plain text. Table 5-1 lists error messages shown by the LaserLight remote display and their meaning.
