2. TEDS IEEE 1451.4 INTRODUCTION

The SSI Smart Sensor Indicator is a TEDS IEEE 1451.4 Plug and Play Smart Load Cell

Meter.
TEDS, or Transducer Electronic Data Sheet, is a set of electronic data in a standardized

format defined within the IEEE 1451.4 standard. The data is stored in an EEPROM with the
sensor. It specifies what type of sensor is present, describes its interface, and gives tech­nical information such as sensitivity, bridge type, and excitation.

The SSI automatically detects when a TEDS IEEE 1451.4 compliant Load Cell, Torque
Sensor or Pressure Transducer is connected. Once a TEDS sensor is detected, the SSI

displays “TEDS”, reads the EEPROM, stores the information in memory, and performs an

automatic configuration.
The built-in sensor-related EEPROM may be any of the following types: DS1973/DS2433,

DS2431 or DS1971/DS2430A. The automatic system configuration function performs all
steps needed to calibrate the TEDS IEEE 1451.4 compliant sensor and SSI as a system.
This includes the configured precision of either 32 bits, 19 bits or 11 bits.

Using the SSI with a TEDS IEEE 1451.4 compliant Load Cell, Torque Sensor or Pressure
Transducer is as easy as plugging a mouse into a computer, making it a true plug-and-play
experience.

The SSI may also be used with a non-TEDS sensor requiring manual configuration and
calibration.

load, torque or pressure applications. Advanced capabilities include:

1. “Plug and Play” operation with automatic scaling at power-up with TEDS IEEE 1451.4
compliant load cells.

2. Instrument Calibration indicator (CAL INSTRUMENT) to show when the meter is due
for calibration. Flashing indicates either that the instrument is due for calibration or will
be due in less than 30 days. Steady indicates that the instrument is now due for
calibration.

3. Sensor Calibration indicator (CAL SENSOR) to show when an actively attached TEDS
sensor is due for calibration. Flashing indicates either that the sensor is due for
calibration or will be due in less than 30 days. Steady indicates that the sensor is now
due for calibration.

4. Calibration Indicators can be enabled or disabled.

5. Menu-driven scaling of non-TEDS-compliant load cells via keypad with a choice of two

scaling methods: manually entered coordinates of two points, or reading coordinates
of two points using input signals.

7. KEYPAD OPERATION

GENERAL

The SSI operator panel consists of an LCD display, an 8-key
membrane keypad, and 5 LED indicator lights, as explained
below.

LCD DISPLAY

8.8.8.8.8.8.

Main reading. This can be the current reading, recalled read­ing, first peak, peak, or valley, as selected via the keypad.
The numerical reading utilizes 5 digits with leading zero
blanking and a selectable decimal point. The 6th left-most
digit is used for special applications, such as setting time and date.

Pa psi bar oz lb ton Mton g N kgf KN
in-oz in-lb ft-lb kgf-m kgf N-m kgf-cm N-cm

Unit of measure associated with the main reading. When changed, readings are automatic­ally converted within the same family (load, torque or pressure). In TEDS operation, a
default unit of measure is read from EEPROM memory in the TEDS unit at power-up, but
can be changed via the keypad.

CAL INSTRUMENT

Flashing indicates either that the instrument is due for calibration or will be
due in less than 30 days. Steady indicates that the instrument is past due for
calibration. See Section 10, Item 10 for a more detailed explanation.

CAL SENSOR

Flashing indicates either that the sensor is due for calibration or will be due in
less than 30 days. Steady indicates that the sensor is past due for calibra­tion. See Section 10, Item 10 for a more detailed explanation.

- 13 -

TEDS Indicates that a TEDS sensor is present, as detected by a jumper across

pins 3 and 4 of the DB9 connector, and that plug & play has been selected.

FIRST PEAK Indicates that main reading is First Peak (or first maximum) since last reset.
PEAK Indicates that main reading is the Peak (or maximum) since last reset.
VALLEY Indicates that main reading is the Valley (or minimum) since last reset.
USB Indicates that serial data is being transmitted.
RECALL Indicates that main reading is recalled logged data.

Battery charge indicator with 4 bars to show percent of full charge. 4 bars =

80% to 100%, 3 bars = 60% to 80%, 2 bars = 40% to 60%, 1 bar = 20% to
40%, flashing battery symbol = 0% to 20%.

8 8 8 8 8 Memory location # from 0 to 15999. Used for data logging or data recall,

when these functions are in effect. Indicates FAST for FAST Mode, when a
conversion rate faster than the normal 60/second has been selected. When
not in the FAST mode, indicates a 10 multiplier when the reading is divided
by 10 for a TEDS sensor having a Max Physical Value greater than 100,000.

INDICATOR LIGHTS

Top left (amber): Alarm 1 activated.
Top middle (green): Go (no alarm). Light may be deactivated to conserve power.
Top right (red): Alarm 2 activated.

 POWER key (amber): ON when battery is charging, otherwise OFF.
 LOG key (green): ON when meter is logging or recalling data, otherwise OFF.

KEYPAD KEYS

POWER Press POWER to turn on the meter. The LCD will come on, and the meter will

be in the RUN mode. Press POWER again to turn off. Automatic power shut-off
may also occur after a pre-selected fixed interval of non-use (no switches
pushed), or this feature may be disabled. Three time intervals are menu­selectable (15, 30 or 60 minutes), as is an optional audible warning 20 seconds
prior to shut-off.

UNITS Press UNITS repeatedly in the Run mode to step from one unit of measure to

the next within the same family of units. These are available for load (oz, lb,
ton, Mton, g, N, kgf, kN), torque (in-oz, in-lb, ft-lb, kgf-m, N-m, kgf-cm, N-cm), or
pressure (Pa, psi, bar). Readings are automatically converted within each
family as units of measure change. In TEDS operation, a default unit of
measure is always read from the transducer at power-up. In non-TEDS
operation, units are selected during meter setup, and the last menu-selected
unit of measure is recalled at power-up.

Press UNITS in the Recall mode to display the last meter calibration date. Press

RECALL to display the previous Recall value.

LOG From the RUN mode, press LOG momentarily to log the current reading into the

next available Memory location # (from 0 to 15999). Press LOG for longer than
2 seconds to place the meter in the Continuous Logging mode, which will log
multiple readings at a programmable data collection rate. Press LOG momen­tarily again to exit the Continuous Logging mode.

The action of the LOG key is menu-selectable. Logging can be disabled, to

internal memory only, to USB only, or to both internal memory and USB.
Please see Section 9, “Data Logging & Recall Operation.”

RECALL From the RUN mode, press RECALL for longer than 2 seconds to change to the

RECALL mode, where previously logged readings can be recalled, as opposed
to taking new readings. Press LOG momentarily to recall single logged
readings. Press LOG for longer than 2 seconds to recall successive readings
continuously. The Memory location # of each recalled reading will be shown in
the 88888 field. Press LOG momentarily to terminate the Continuous RECALL
mode. Press UNITS in the Recall mode to display the last meter calibration
date. Press RECALL to display the previous Recall value. Press RECALL for
longer than 2 seconds to return to the RUN mode. Please see Section 9, “Data
Logging & Recall Operation.”

> MENU From the RUN mode, Press > MENU to change to the Menu mode, which allows

setting up the meter from the keypad. Press > MENU to step through menu
items. Press > PEAK to select digits or sub-items within the selected menu item,
and press TARE ^ RESET to modify the selected flashing digit or sub-item. The

UNITS, RECALL and LOG keys are disabled in the Menu mode. Please see

Section 11, “Menu Mode Programming Keystrokes.”
The > MENU and < ALARMS keys are also used in the RECALL mode to incre-

ment or decrement Memory location #’s (from 0 to 15999) for displaying logged
readings.

> PEAK The action of the > PEAK key is programmable to 4 operating modes, so that

pressing it from the RUN mode will display 1) Peak, 2) First Peak, 3) Valley, 4)
Peak (1st push) and Valley (2nd push). When Peak, Valley or First Peak is being
displayed, the appropriate LCD indicator caption will be displayed (PEAK,

VALLEY or FIRST PEAK). Pressing the > PEAK key one more time returns to the

RUN mode.

The > PEAK key is also used in the Menu mode to advance the flashing

indicator of the menu value, and in the RECALL mode to advance the next
flashing digit of the logging Memory location # (0 to 15999).

TARE ^ RESET

To zero the display from the RUN mode, press TARE ^ RESET (selectable Tare

function). With no load applied, this action will zero the system. If the meter is
used in a weighing application with an empty container, this will subtract the
weight of the empty container to display net weight.

To reset the meter, hold the TARE ^ RESET key depressed while you press and
release the > MENU key.

To reset a Peak, Valley or First Peak, hold the TARE ^ RESET key depressed

while you press and release the > PEAK key.

To reset latched Alarms, hold the TARE ^ RESET key depressed while you press

and release the < ALARMS key.

The TARE ^ RESET key is also used in the Menu mode and in the RECALL

mode to increment the flashing selection.

< ALARMS From the RUN mode, press < ALARMS to change to the Alarms mode, which

allows viewing and changing setpoints from the keypad. Press once to view
Setpoint 1. The Alarm 1 indicator (amber LED) will light. Press again to view
Setpoint 2. The Alarm 2 indicator (red LED) will light. Press again to exit the
Alarms mode and return to the RUN mode. While the Alarm 1 indicator is lit,
you can change Setpoint 1 by pressing > PEAK to select a digit, which will flash,
then pressing TARE ^ RESET to increment that digit. Same for Setpoint 2.

In the Menu mode, the > ALARMS key steps backward through the menu. In the
RECALL mode, it is used to decrement Memory location #’s from 15999 to 0.
