INTRODUCTION

The TI-1520 Digital Indicator is a general purpose, industrial grade weight indicator. One model is

currently available, distinguishable by display type, enclosure type and power supply. Table 1 shows the

TI-1520 product matrix.

This model can readout up to 50,000 display divisions and can supply enough current for up to 8-350Ω

load cells. All setup parameters may be entered via the front panel keys, including calibration.

If your Model TI-1520 Digital Indicator is part of a complete floor scale or has already been installed for

you, you may skip to the operating instructions. Prior to using the indicator, please read this chapter

carefully and completely. Store the manual in a safe and convenient place so it will be available if you

have questions concerning the operation of the scale.

FCC NOTE

Note: This equipment has been tested and found to comply with the limits for a Class B digital device,

pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against

harmful interference in a residential installation. This equipment generates, uses and can radiate radio

frequency energy and, if not installed and used in accordance with the instructions, may cause harmful

interference to radio communications. However, there is no guarantee that interference will not occur in a

particular installation. If this equipment does cause harmful interference to radio or television reception,

which can be determined by turning the equipment off and on, the user is encouraged to try to correct the

interference by one or more of the following measures:

—Reorient or relocate the receiving antenna.

—Increase the separation between the equipment and receiver.

—Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

—Consult the dealer or an experienced radio/TV technician for help.

INSTALLATION

PREPARATION

Any precision instrument requires a suitable environment in which to operate as intended. Please review

each of the following prior to installation:

Electrical Power

The TI-1520 indicator has been designed to operate from 100 to 240 VAC at 50/60 Hz. All units ship with

the appropriate power plug for its area of intended use.

To avoid electrical noise interference and/or stray AC electrical transients, try to operate the indicator

from a circuit separate from any equipment containing inductive devices such as a contactor coil,

solenoid, relay coil, or motor. Be sure to use shielded cables for the load cell connections (ground shield

wire at indicator) and run these cables away from your AC/DC power cables if possible.

In extreme cases, it may be necessary to install surge suppressors, line conditioners or even UPS

(Uninterruptible Power Supplies) systems (not included).

Environment

-Avoid installing the indicator in areas of direct sunlight or high humidity

-Avoid sudden temperature change – if this is unavoidable allow equipment to ‘soak’ at a constant

temperature for at least three hours before use

-Ensure that steady, clean AC power is available to the unit

Remember that the installer is ultimately responsible to assure that a particular

installation will be and remain safe and operable under the specific conditions

encountered.

CONNECTIONS

The rear cover must first be removed to make the appropriate connections to the weigh platform, printer,

remote display and power supply. To remove the rear cover, simply remove the screws that secure it to

the enclosure and set aside.

Caution! Disconnect power source from indicator prior to removing rear cover.

CONNECTING THE WEIGH PLATFORM

ATTENTION INSTALLERS:

It is highly recommended that you install the enclosed green/yellow cable between

the load cell cable shield and the AC ground lug on the main PCBA. Do not connect

the load cell cable shield to the green load cell input terminal.

The TI-1520 indicator contains a connection terminal on the main board for connection to the load cell

cable. Connect your shielded load cell cable (not included) to the appropriate terminal on the main

board. NOTE: 6-wire connection is optional.

CONNECTING THE SERIAL I/O DEVICE

The TI-1520 model comes standard with one full duplex RS-232 serial port, designed for connection to a

computer or a serial printer. The same port may be also used as a simplex, RS-232 port designed for

connection to a remote display.

Connection assignments for all serial RS-232 communication terminals on the TI-1520 are shown below.

CONFIGURATION

OVERVIEW

The indicator contains two main configuration menus:

•The Setup (“F”) menu, which configures the indicator to your weigh platform

•The User (“A”) menu, which configures the serial communication port and enables some user

options

The Setup and User menus consist of several menu selections, each with its own sub-menu of selections

or programming procedures. To configure the indicator you must first enter the appropriate menu mode.

Once there, four of the front panel keys become directional navigators to move around in the menus,

and one key is used to save or SET the selections.

ACCESSING THE MENUS

To access the Setup (“F) menu:

1. Power off the indicator.

2. Locate the slide switch on the rear cover and move it to the opposite position.

NOTE: A metal plate held on by two drilled-head screws may conceal the slide switch.

3. Power on the indicator.

The display shows ” F 1” to indicate that you are in Setup Menu mode.

4. Use the navigation keys shown in the figure below to move through the menu.

To access the User (“A) menu:

1. Enter the Setup (“F”) menu.

2. Use the right or left directional keys shown below to move right or left in the Setup (“F”) menu

until the indicator shows ” A 1”.

MENU STRUCTURE

All menus consist of a top level (heading) and a secondary level. The top level contains the code (e.g.

F1) for the parameter to be configured. The secondary level contains the selection list or allows access

to a programming sequence.

Use the directional keys to move around in the Menu Structure shown below.

Etc.

1. To move to a new heading, use the TARE (left) or PRINT (right) key to move right or left

in the Menu.

2. To move to the selection or programming level, press the ZERO (down) key once. The

currently saved selection is shown.

3. To view the available selections for the current heading, use the TARE (left) or PRINT

(right) key to move through the selection field.

4. To save a new selection, press the NET/GROSS (Set) key .To exit without saving, press

the UNITS (up) key to return to the current heading.

5. Repeat Steps 2 through 5 until the Menu is programmed.
