INSTALLATION

Unpacking Carefully unpack and remove the indicator from the packing box. Inspect the unit for any signs of damage due to shipping, such as exterior dents and scratches. Retain the packing and shipping carton for return of instrument if necessary. It is the responsibility of the Purchaser to file all claims for any damages or loss in transit incurred, unless the responsibility has been accepted by the Seller in its proposal. Placement See the UPS Installation Manual for instructions. Refer to Figure No. 1 on the next page for dimensions and placement of system components.

SITE PREPARATION REQUIREMENTS The 788 Programmable Weight Indicator is a precision measuring instrument. As with any precision instrument, it requires an acceptable environment to operate at its peak performance and reliability. This section is provided to assist you in obtaining such an environment. Electrical Power The 788 is designed to operate from 90 to 260 VAC at 50/60 Hz. However, heaters and other parts are different in 115V or 230V AC Input models. Verify before installing that the unit is rated for available power source.

Caution!!! - To avoid electrical hazard and possible damage to the indicator, DO NOT, under any circumstance, cut, remove, alter, or in any way bypass the power cord grounding prong.

On models requiring 230 VAC power, it is the responsibility of the customer to have a qualified electrician install the proper power cord plug which conforms to national electrical codes and local codes and ordinances. The power outlet for the 788 should be on a separate circuit from the distribution panel. This circuit should be dedicated to the exclusive use of the indicator. The wiring should conform to national and local electrical codes and ordinances and should be approved by the local inspector to assure compliance. To prevent electrical noise interference, make certain all other wall outlets for use with air conditioning and heating equipment, lighting or other equipment with heavily inductive loads, such as welders, motors and solenoids are on circuits separate from the 788. Many of these disturbances originate within the building itself and can seriously affect the operation of the instrument. These sources of disturbances must be identified and steps must be taken to prevent possible adverse effects on the instrument. Examples of available alternatives include isolation transformers, power regulators, uninterruptible power supplies, or simple line filters.

INTERCONNECTIONS Load Cell Connection With Over 30 Feet Of Cable For installations with over 30 feet of cable between the indicator and the load cells, sense wires should be used. The sense wires must be connected between the +SENSE, -SENSE terminals on the indicator and the +EXCITATION, -EXCITATION wires of the load cells or the +SENSE, -SENSE terminals of the load cell trim board or the section seal trim board. For the indicator to use the sense wires, the SENSE jumpers J5 and J6 must be open on the Scale Input Board. Load Cell Connections 788SUPS-1 AND 788SUPS-2 These models are designed to be retrofitted to the existing platform scales. In doing so, it is the intention of UPS to keep the existing scale weight indicator as a back-up weight indicator. This can be done quickly using the weather-resistant military plugs, if properly installed. Since the 788SUPS-1 and 788SUPS-2 units have the military plug female version installed on the indicator bottom, the scale will require wiring the male mating connector into the scale load cell cable. Similarly, wiring a female connector into the cable coming out of the existing weight indicator will enable easy switchover of the scale from the 788SUPS-1 and 788SUPS-2 unit to the existing weight indicator. Both the existing indicator and the 788SUPS are calibrated to work with the scale base. The male connector from the scale, and the female connector from the existing weight indicator, should be installed using the pin wiring table shown in the Figure No. 2. Refer to Figure No. 3 to compare the present scale layout with the new layout. Note that with the new layout, the scale can be connected to the new unit or the existing indicator.

SERIAL I/O CONNECTIONS The 788 comes standard with two bi-directional serial ports that are used as I/O. These ports are wired to a serial transition board. The external devices are then wired to the terminal strip either via a direct connection or through the use of a short pigtail cable with connector. The 788 units provided to UPS will have a model 778C serial card for COM3 (25pin) and COM4 (9pin). The COM4 will be used for the second bar code scanner on the two scale system. The COM3 is reserved for a possible future printer. The bar code scanner gun # 1 is connected to the short pigtail connector (9 pin) from the RS232 (COM1). The Lantronix Ethernet device is connected to the pigtail connector (9 pin) from the RS232 (COM2). The second scales bar code scanner gun # 2 is connected to the short pigtail connector (9 pin) from the RS232 (COM4). Figure No. 5 on the next page, illustrates the connections. Figure No. 4 illustrates the pin location of COM1 and COM 2 as viewed from the cable attachment side. Refer to the table below for the identity of the pins used.

6. The screen will prompt: Z LIMIT, for the zero tracking range limit and display the current setting. If YES is displayed, the push button zero and zero tracking features are limited to a maximum of 4% of the scale capacity. If NO is displayed, the push button zero and zero tracking feature will operate up to the full capacity of the scale. To change the setting, use the keypad to select a YES or a NO, then press the [ENTER] key to save the setting and proceed to the next step.

7. The screen will prompt: FILTER, for the digital filtering and display the current setting. Four

(4) levels of filtering (0, 1, 2 and 3) are available. They are as follows:

0 = NO FILTERING 2 = MODERATE FILTERING 1 = MINIMAL FILTERING 3 = CUSTOM FILTERING

To change the setting, use the keypad to select a new value for the digital filtering, then press the [ENTER] key to save the setting and proceed to the next step.

NOTE! Custom filtering, three (3) is used when zero (0), one (1) or two (2) are inadequate. If you select custom filtering, the 788 will display two (2) more prompts.

If you selected Custom Filtering (3), the 788 will prompt: F MAX for the maximum filter level and display the current setting. The filter level is a number from 1 to 256 that corresponds to the level of filtering with 256 being the greatest filtering and 1 the least. To change the setting, use the keypad to select a new maximum filter level, then press the [ENTER] key to save the setting and proceed to the next step. Next, the 788 will prompt: F BREAK, for the filter break range and display the current setting. The break range is a number from 1 to 64 that corresponds to the number of division change to break out of filtering. To change the setting, use the keypad to select a new value for the filter break, then press the [ENTER] key to save the setting and proceed to the next step.

8. The screen will prompt: MOTION, for the range of motion detection and display the current

setting. Changes in weight exceeding the selected number of divisions will cause the - MOTION - message to display. To change the setting, use the keypad to select a new value from 0 to 9 divisions for the motion range, then press the [ENTER] key to save the setting and proceed to the next step.

9. The screen will prompt: S RATE, for the sample rate and display the current setting. The

value displayed is the sample rate in samples per second. To change the setting, use the keypad to select a new value from one (1) to sixty (60) samples per second for the sample rate, then press the [ENTER] key to save the setting and proceed to the next step.

14

SETUP AND CALIBRATION, Cont.

10. The screen will prompt: C1, the current value of the C1 number. If the 788 was calibrated previously and you recorded the four (4) "C" (calibration) numbers, you may enter the value for C1. By entering the "C" numbers previously recorded, you can return to that calibration setting without having to use test weights.* If you wish to use test weights for calibration, leave the C1 value unchanged and press the [ENTER] key.

* If any components have been changed that affect calibration and your scale is used in a commercial application and must be "Legal for Trade" you can not use "C" numbers to re-calibrate.

11. The screen will prompt: CAL WT 1, the first of two calibration weights and display the

current setting. This setting could be ZERO (NO LOAD) or the TEST WEIGHTS (TEST LOAD). If the first calibration weight is to be ZERO or NO LOAD, use the keypad to input a 0, then press the [ENTER] key. If the first calibration weight is to be the TEST WEIGHTS or TEST LOAD, use the keypad to input the value of the calibrated test weights. Place these weights on the scale platform, then press the [ENTER] key.

12. After a few seconds, the screen will prompt: CAL WT 2, the second of two calibration

weights and display the current setting. If the first calibration weight was ZERO or NO LOAD, this weight should be equal to the test weight total. If, however, the first weight was the test weight total, then this weight should be zero.

If this second calibration weight is to be zero, make certain the scale platform is empty, use the keypad to input a 0, then press the [ENTER] key. If this second calibration weight is to be the test load, use the keypad to input the value of the calibrated test weights. Place the weights on the scale platform, then press the [ENTER] key.

13. After a few seconds, the screen will prompt: FINE SPAN ADJUSTMENT. Place a known

weight on the scale. Any small error will be displayed and can be corrected as follows:

Press the [UP] key to increase displayed weight 1 grad per press.

Press the [DOWN] key to decrease the weight 1 grad per press.

Press the [ZERO] key to zero the scale.

Press the [EXIT] key to save the settings and proceed to the next step.

14. After a few seconds, the screen will display: CAL DONE, SCALE X CALIBRATED and the “C” numbers. Note that X = the scale number. This indicates the setup and calibration process has been completed. The "C" numbers displayed should be recorded for future use. After recording the "C" numbers, press the [EXIT] key.

15

SETUP AND CALIBRATION, Cont.

15. The screen will prompt: OIML (YES OR NO) to determine whether or not the indicator will be used in an application requiring a protective interface.

When YES is selected, serial port COM1 will be dedicated to outputting scale gross weight whenever the BASIC application is executing. The BASIC application will not be able to manipulate this output in any way. The serial port communications parameters will be 9600 baud, 8 data bits, no parity bits and 1 stop bit. The format of the data will be:

<lf><s><r><n><m><f><xxxxxx.xxx><uuu><cr>

where:

<lf> = line feed <s> = status flags:

Z for center of zero, O for overcapacity, otherwise, a space

<r> = 1 <n> = G <m> = motion status:

M if scale is in motion, space if not <f> = scale number:

1 for scale 1, 2 for scale 2, etc. up through 9 for scale 9. A is for scale 10, B for scale 11, and so on.

<xxxxxx.xxxx> = weight <uuu> = units (lb or kg ) <cr> = carriage return

The data will be sent out at a rate of from 1 to 2 times per second, depending upon the sample rate.

To change the setting, use the keypad to select a YES or a NO, then press the [ENTER] key to save the setting and proceed to the next step.

The instrument will reset, display the Start Menu and then advance to the Weight Screen. Replace the calibration sealing screw on the scale input board, and proceed with normal operations.

NOTE! Changes to the 788 setup parameters can be performed WITHOUT affecting the calibration. This is accomplished by entering the changes necessary up to the screen prompt C1 and pressing the [ENTER] and [ESC] keys. That is, follow the standard Setup and Calibration procedure up to the screen prompt, C1. Then instead of entering a value for C1, press the [ENTER] key, then at the CAL WT 1 prompt, press the [ESC] key. The instrument will reset, display the Start Menu and then load the application program or standard program. Replace the calibration sealing screw on the scale input board, and proceed with normal operations.

This allows inputting new Setup parameters, without the need to re-calibrate the scale.

16

SCALE TOTALIZER

The scale totalizer will sum the weights of two or more scales and make the total available to the application program. The totalizer can be referenced as if it were another scale. The totalizer’s scale number will be one plus the actual number of scales attached to the indicator.

Setup To setup the totalizer, remove the calibration sealing screws from all scale cards and press the [SETUP] key on the indicator’s main menu. If the scale cards have not been setup, continue with the scale card setup. Otherwise, at the SCALE ID prompt, bypass the scale card setup screens by pressing the [ESC] key. The display will change to show:

TOTALIZE (YES OR NO) CURRENT=??

Selecting NO (and pressing the [ENTER] key) will disable the scale totalizer. Selecting YES (and pressing the [ENTER] key) will enable the scale totalizer. Pressing the [ESC] key will leave the selection as is and proceed to the next setup function or back to the main menu. If YES is selected (and the [ENTER] key pressed), the display will show:

INCLUDE SCALE 1

CURRENT=?? Selecting YES (and pressing the [ENTER] key) means that weight from scale 1 will be used by the scale totalizer. Selecting NO (and pressing the [ENTER] key) means that scale 1 will not be a part of the totalizer. Note, that all the scales to be included in the totalizer must have the same scale division value (interval and decimal point precision), sample rate, and weight units. If this is not true, the error message:

INVALID SETUP FOR TOTALIZE

will be displayed. Press the [ESC] key to return to the INCLUDE SCALE prompt and select NO, then press the [ENTER] key to proceed to the next setup function. In addition, the firmware for the 778A card must be version 00.4 or higher, and the firmware for the 778K card must be version 00.2 or higher. If this is not true, the error message:

INVALID REV FOR TOTALIZE

will be displayed. Press the [ESC] key to return to the INCLUDE SCALE prompt and select NO, then press the [ENTER] key to proceed to the next setup function.

17

SCALE TOTALIZER, Cont.

After the appropriate selection for including scale 1 has been entered, the display will ask if scale 2 should be included in the totalizer. The question will be repeated for each scale attached to the indicator. The display will then change to show:

CAPACITY (1 TO 9,999,999) CURRENT=??

The value entered, in primary weight units, will be used in determining when the totalizer’s overcapacity status will become true. The totalizer’s overcapacity status will be true if any scale is overcapacity or if the total gross weight exceeds the totalizer capacity by more than 9 scale divisions. After the totalizer capacity has been entered, the display will show:

MOTION (0 TO 9)

CURRENT=??

The value entered, in scale divisions, will be used in determining when the totalizer’s motion status will become true. The totalizer’s motion status will be true if any of the totalized scales is in motion or if the total gross weight changes by more than totalizer’s motion range. This completes totalizer setup. Operation When operating in STD mode, the totalizer will be identified by a T. The [TARE] key will not be active when the display is showing the totalizer weight. If the [ZERO] key is pressed while displaying the totalizer weight, all of the scales included in the totalizer will be zeroed. If the [ZERO] key is pressed while displaying a scale weight, only that scale will be zeroed. If pounds-kilograms conversion is enabled, pressing the [UNITS] key, when displaying the totalizer or any of the scales included in the totalizer, will switch the weight units of the totalizer and the weight units of all the scales included in the totalizer. Program Commands The application program can use the standard scale commands and functions to access the totalizer. The totalizer may be accessed by using the totalizer’s scale number in the command or function, or by using the CURSCALE command to make the totalizer the default scale. The function CURSCALE will return the totalizer’s scale number if the totalizer is the default scale. The function CARDS(17) will return one if the totalizer is enabled, zero if it is not. The SCALES function will return the total number of actual scales, not including the totalizer. The GROSS, TARE, NET functions will return the totals of the gross, tare, and net weights, respectively, for all of the scales included in the totalizer. The CZERO function will return a nonzero value if and only if all of the scales included in the totalizer are at center of zero. The MOTION function will return a nonzero value if any of the scales included in the totalizer is in motion, or if the totalizer gross weight changes by more than the totalizer motion range.

18

SCALE TOTALIZER, CONT.

The OVERCAP function will return a nonzero value if any of the scales included in the totalizer is overcapacity, or if the totalizer gross weight is overcapacity. An error condition for the totalizer or any of the scales included in the totalizer will also cause OVERCAP to return a nonzero value. The BLOZERO function will return a nonzero value if the gross weight of any of the scales included in the totalizer is below zero, or if the totalizer gross weight is below zero. The CAPACITY function will return the capacity of the totalizer. The INTERVAL function will return the scale division value for the totalizer. The totalizer and all of the scales included in the totalizer must have the same scale division value. The WTMODE function will return 1 if the totalizer displays weight in pounds only, 2 if the totalizer displays weight in kilograms only, and 3 if the totalizer displays weight in pounds and kilograms. The totalizer and all of the scales included in the totalizer must have the same weighing mode. The CURUNIT function will return 0 if the totalizer is weighing in pounds, 1 if it is weighing in kilograms. The UNIT$ function will return "LB" if the totalizer is weighing in pounds, "KG" if it is weighing in kilograms. The TARETYPE function will return 0 if no tare is stored, 1 if a tare was stored for at least one of the scales included in the totalizer using the DOTARE command, and 2 if a tare was stored for at least one of the scales included in the totalizer using the TARE command. All tare weights stored for the scales included in the totalizer must be of the same type. The SCLSTAT function will return information about the scale’s status. The information is encoded in the bits of the return value and can be determined by AND’ing the return value with the appropriate mask value: SCLSTAT AND 2 = 1 = One or more of the scales included in the totalizer had some sort of

failure or the total weight could not be calculated because the scales were incompatible.

SCLSTAT AND 8 = 1 = Analog failure of one or more of the scales included in the totalizer.

SCLSTAT AND 32 = 1 = This scale is included in the totalizer.

SCLSTAT AND 64 = 1 = This scale is the totalizer. The CURUNIT command can be used to set the weight units for totalizer and its associated scales if pounds-kilograms conversion is enabled. The totalizer and all of its associated scales will be set to the same units when the command is executed. The DOZERO command can be used to individually zero any of the scales associated with the totalizer. If the totalizer is specified as the target of the command, all of the scales included in the totalizer will be zeroed.

SCALE TOTALIZER, CONT.

The DOTARE command can be used to individually tare any of the scales associated with the totalizer. If the totalizer is specified as the target of the command, it is as if the command were repeated once for each scale included in the totalizer. If a keypad tare has already been stored for one or more of the scales included in the totalizer, the DOTARE command can only be used to clear the tare (that is, the gross weight is 0). It cannot store a new tare since that could result in more than one type of tare being stored. The TARE command can be used to individually tare any of the scales associated with the totalizer. The command cannot be used with the totalizer. If a pushbutton tare has already been stored for one or more of the scales included in the totalizer, the TARE command can only be used to clear the tare (that is, set the tare to 0). It cannot store a new tare since that could result in more than one type of tare being stored.

ERROR AND STATUS MESSAGES The 788 is equipped with a diagnostic software program that tests various portions of the instrument’s circuitry and verifies proper operation. Should a problem be detected, an error or status message will be displayed alerting the operator to that condition. The following lists these errors and status messages and their meaning.

Message

POSSIBLE CAUSE CORRECTIVE ACTION

��������

This message indicates that motion is present when attempting to power up, print, zero or perform a push button tare function.

Insure scale is stable, level and vibration-free. Wait for a stable weight display.

������

The ZERO key was pressed when the gross weight is outside the scale zero weight range.

Check Setup parameter Z LIMIT. If YES, only 4% of scale capacity can be zeroed. Change as required.

����� � �����

This message indicates the weight on scale exceeds the scale capacity.

Remove the weight from the scale platform. Insure the scale is at zero. If problem persists, contact your scale serviceman.

�����������

Scale Input Board (SIB) data interface not functioning.

Both data and power cables must be plugged into SIB. If cables check okay, replace SIB.

� ��� �

Attempting to enter Setup and Calibration mode with the calibration sealing screw installed.

Remove the calibration sealing screw from the Scale Input Board (SIB) mounting bracket (refer to Figure No. 10).

�����������

This message is displayed to indicate that the weight is within +/- 1/4 division of the center of zero.

No corrective action is necessary. This is a status message indicating the automatic zero tracking is working properly.

There are many operating system error codes. These errors are rare.

The cause for an operating system error may be caused by bad RAM disk memory. This memory may be corrupted by several causes.

The corrective action is to follow the procedure for clearing of RAM memory. In doing this all RAM memory is cleared therefore clearing all RAM disk files.

29

BEFORE YOU CALL FOR SERVICE The 788 has been designed to provide you with years of trouble-free operation. In spite of this, troubles sometimes happen. Before calling for service assistance you should make some initial checks to verify that a problem does exist. The following describes several types of symptoms along with suggested remedies.

Problem Possible Solutions Screen does not turn on Is AC power cord plugged into wall

receptacle? Check wall receptacle for proper AC power. Try another electrical appliance in the same receptacle, does it work? Check the circuit breaker. Has there been a power failure of any kind?

Incorrect weight displayed Has the instrument been calibrated? Insure that the scale platform isn’t touching an adjacent object. Check the load cell connector wiring. Have proper operation procedures been followed?

Indicator will not display weight Refer to Error and Status Messages section.

30

PROBLEM RESOLUTION 788 Problem Resolution Overview From time-to-time, it may be necessary to perform some on-site troubleshooting

when the Automated Ramp Scale equipment or its associated systems are not responding as expected.

The following tables should always be referenced as a first step in determining the cause of the problem.

788 Programmable Weigh Indicator - Problem Resolution Table

Problem Possible Cause Solution No Display � No Power

� Disconnected display cable

� Turn on power to 788 � Reconnect display

ribbon cable (either at the inside, front panel, or at the Main Circuit Board inside)

Vertical lines on LED � Damaged display

ribbon cable � Partially disconnected

display ribbon cable

� Power off 788 and check cable for damage and replace if necessary

� Power off 788 and reseat display cable at LED and Main Circuit Board

“No Response from Operator” message is displayed

� Timeout occurred, operator failed to press an available option after scanning/keying ULD data.

� Re-process the ULD

788 is “Locked-up” or “Won’t Respond”

� Unit too cold � Power surge � If intermittent, ASMA

(Scale Host) isn’t running

� Power on and allow to warm up 10-15 minutes before use (especially in cold weather)

� Power off, wait 5-10 seconds and power back on

� Verify that ASMA (Scale Host) is running

31

Problem Resolution, Cont. 788 (continued)

Problem Possible Cause Solution “Server Not Connected” message is displayed

� Lantronix device not receiving AC power

� Ethernet switch functioning improperly

� May also be caused by a faulty Lantronix Device Server

� Verify that AC adapter is plugged in

� Verify Ethernet switch functions

� Verify that the Lantronix Device Server is functioning properly.

PSC Scanner won’t scan It has a solid green LED

� System lock-up � Defective scanner

� Power the 788 off for 5-10 seconds and restart

� Replace the PSC Scanner

PSC Scanner won’t scan It appears to have a red LED when the trigger is pressed and the scanner emits a scan beam

� Dirty lens � Cracked/scratched lens � Condensation inside

scanner

� Clean lens � Replace scanner if lens

is cracked/scratched or if condensation exists

PSC Scanner won’t scan No lights are working

� Internal disconnect � Defective scanner

cable � Defective pigtail � Defective scanner

� Verify that scanner is connected to appropriate COM port

� Verify that COM port pigtail is properly terminated

� Try a replacement scanner cable

� Try a replacement pigtail cable

� Replace the scanner

Scanner works fine, but occasionally will not read all ULD barcodes

� Barcode damaged � Too faded for scanner

to decode

� Press the ULD button for the corresponding scale and type in the ULD number including the IATA code, the ID number, and the owner code (i.e., AAY8281UPS - where AAY is the IATA code, 8281 is the ID number, and UPS is the owner code)

32

788 Problem Resolution, Cont. 788 (continued)

Problem Possible Cause Solution Scale doesn’t show zero (0) weight when nothing is on the scale.

� Environmental conditions (i.e., strong wind)

� Access the Zero Scale option to reset the scale to zero (make sure nothing is on the scale)

“Server App Active” message is displayed.

� This is not a problem, it is a normal system response to a periodic communication test

� When no activity takes place, the 788 will periodically send a “Heartbeat” message to the ASMA (Scale Host) to make sure it can still communicate to it

Strange number show up on the 788 display that are not valid weights

� Improperly terminated scale input cable

� Verify that the scale input cable is terminated on the 788 Indicator connector instead of the Existing indicator connector

33

ASMA Problem Resolution Overview The Automated Scale Monitoring Application (ASMA) is responsible for gathering

and storing ULD data collected at the scales. In the event that data related problems occur, ASMA may be the cause. The following problem resolution table should be referenced if ASMA is believed to be the cause of a data related problem.

ASMA Automated Scale Monitoring Application (ASMA) Problem Resolution Table

Problem Possible Cause Solution ULD’s have been processed, but some are not automatically updating in DWB

� ULD’s were processed as “Load Not Found”

� Load Not Found ULD’s do not update on the DWB Server

� Scale operator failed to accept or reject the returned load information

� Scale operator will need to press “ACCEPT” after this message displays to save data locally on the ASMA host or “REJECT” to discard it and begin again

� Data can then be queried to obtain the capture

A specific ULD can not be found using the query function

� Improperly entered ULD number

� ULD was originally weighed more than seven days ago.

� Re-enter the ULD number (with or without the IATA and owner codes)

� Verify that the ULD was weighed less than seven days ago, otherwise it has most likely been purged from the system

34

DWB Problem Resolution Overview Data collected through the Automated Ramp Scales are transmitted via the

ASMA Scale Host and used to populate the Distributed Weight and Balance (DWB) system with valid ULD weights. On occasion, there may be reason to question the data being populated into the DWB system. This problem resolution table offers a starting point for resolving such issues.

DWB Distributed Weight and Balances (DWB) Problem Resolution Table

Problem Possible Cause Solution The weights are not updating for the ULDs

� In connected mode, but screen hasn’t been refreshed.

� Not in connected mode.

� In connected mode (i.e., a green light appears on the bottom right corner of the screen), simply click the REFRESH button

� If not connected, you must query the ASMA manually and key the capture ULD weights

ULD’s are updating with zero weight

� Container is being scanned or keyed and saved before the container actually reaches the scale

� Wait until the ULD is positioned on the scale and allow the weight to stabilize before scanning/keying the ULD
