Section 2. Legal for Trade
The 460 Series parameter setup does not ensure compliance with legal-fortrade installations as mandated by local weights and measures authorities. This chapter explains how to configure the 460 Series controllers to comply with various regulations and describes other features that will make your controller suitable for installations worldwide.
Legal-for-trade requirements vary by location. Ensure that your controller is installed in accordance with all local regulations.
OIML and International
The International Organization of Legal Metrology is an intergovernmental body, which harmonizes the national metrology regulations of its worldwide members.
A list of regulation publications can be obtained from the Bureau International de
Métrologie Légale (BIML) in Paris, France.
In order to configure the controller to comply with OIML requirements, P410 must be enabled in the Setup Mode. Doing this will ensure the following:
• An over-load condition will result when the gross weight exceeds nine graduations over the full-scale capacity.
•
Full scale capacity is always referenced from the last zero calibration reference, not the last zero acquired by pressing [ZERO
• The keypad is remapped for the international version. manually.
Most NTEP requirements will also apply.
For detailed information on enabling OIML operation, please see the 460
Series Technical Reference Manual.
NTEP
The National Type Evaluation Program (NTEP) is a widely accepted weights and measures standard in the United States. Most states abide by some or all of the requirements set forth by NTEP. A complete list of these regulations is available in the “Handbook 44” publication distributed by the National Institute of Standards
11 OF 20
and Technology (NIST). For more information on this and other NIST publications, visit their web site at http://www.nist.gov.
Enabling NTEP Operation
In order to configure the 460 Series indicators to comply with NTEP requirements, the NTEP parameter (P440) must be enabled in the Setup Mode.
•
•
This will have the following effects on the standard indicator’s operation:
• Pressing with a gross weight of zero (0) or pressing 0 [TARE] will not automatically switch to the net mode.
Negative tare values are not accepted regardless of the selection for the
“Negative Tare Enable” parameter (P162).
Tare values are automatically rounded regardless of the selection for the
•
•
Received serial data will not be processed while in the Setup Mode until
P440 is manually enabled.
Accumulations using the [.] [ENTER] method can only be performed from the gross, net or quantity mode. using key is only possible from the gross, net or
• Weight values that exceed the minimum width specified at P240 will be transmitted as dashes "-------".
Legal-for-trade installations using accumulations require the “number of accumulations” parameter (9) to be accessible when not using a printer. When using a printer, this parameter must be printed on the receipt.
NTEP Custom Setup
The “Custom Setup” parameter, P60205 of the information parameters, displays a list of parameters, which, if configured improperly, could facilitate fraud in a legal-for-trade installation. A weights and measures inspector might check this parameter and inquire about the configuration of any parameters that appear in this list.
12 OF 20
Accessing the Custom Setup List
DO NOT ATTEMPT TO ACCESS THE CUSTOM SETUP LIST DURING
CRITICAL WEIGHT PROCESSING! It is important to note that all functions of the operating mode will be suspended immediately upon accessing the information parameters. This includes suspension of weight conversions, deactivation of all setpoints and cancellation of custom transmits.
The “Custom Setup” list may be accessed from the Weigh Mode. An access code is not required to view this list.
To access the custom setup list:
1 From the Weigh Mode, key in 60205 [SELECT] .
2 The Custom Setup list begins scrolling through each parameter to check.
If there are no parameters to check, Std. Setup is displayed
3 The Custom Setup list may be repeated by pressing [ENTER] at P60205.
4 Press to return to the Weigh Mode.
A setup parameter that appears in the “Custom Setup” does not imply that it is improperly configured. Consider the application and refer to the 460 Series
Technical Reference Manual for more details.
Additional Conformance Considerations
Several parameters must be considered on an individual basis as their configuration may vary with different applications. Refer to the 460 Series
Technical Reference Manual for details.
Sealing and Audit Trails
Most legal-for-trade installations will require the indicator to be sealed. A sealed indicator cannot be accessed for setup or calibration changes without breaking a physical seal or incrementing an event counter, thus providing evidence that the
• unit has been tampered with. Each member of the 460 Series has two types of sealing provisions:
Physical seal used in conjunction with an internal program jumper
• Three-event audit trail counter
Check with your local weights and measures authority to determine which method(s) are required.
13 OF 20
Physical Seal
The most common sealing method is a lead-wire seal. Before applying a wire seal, move the program jumper to the ‘NO’ position located on the indicator main board. Refer to Table 4 for program jumper location. Doing this will prevent access to the setup and calibration modes.
All standard units provide two tamper-proof screws used for sealing the rear panel to the front of the enclosure. A lead-wire seal can be applied by passing the lead-wire seal wire through a hole in these two screws, thus preventing the screws from being removed without breaking the seal. The 460 Series panel mount versions use a lead-wire seal and one screw.

Audit Trail Parameters
Three separate incrementing, non-resettable audit trail parameters are used by the M660 to indicate changes to various parameters:
•
•
P60203 – Calibration
P60204 – Setup
An audit trail counter will increment only once upon exiting the Setup Mode and saving changes regardless of how many settings were changed. Each audit trail counter will increment to 99999 before beginning again at 00001.
DO NOT ATTEMPT TO ACCESS AUDIT TRAIL PARAMETERS DURING
CRITICAL WEIGHT PROCESSING! Weight conversions and custom transmits will be suspended and all setpoints will be deactivated!
Accessing Audit Trails
The audit trails may be accessed from the Weigh Mode. An access code is not required to view audit trail parameters.
To access audit trails:
1. Key in 60201 [SELECT] to access the OIML audit trail.
2. . Key in 60203 [SELECT] to view the Calibration audit trail.
3. Key in 60204 [SELECT] to view the Setup audit trail.
4. Press [ZERO] to return to the Weigh Mode.
Calibration Audit Trail
Any changes to the existing calibration will increment the Calibration audit trail at
P60203. This includes any changes to P60101 Æ P61140 of the information parameters.
Setup Audit Trail
Changes to any of the Setup Mode parameters will increment the Setup audit trail at P60204.

Section 3. Troubleshooting
This chapter of the User Guide provides information on error messages and trouble-shooting 460 Series controllers. Some information in this chapter refers to parameters that are not discussed in this guide. They are provided as a quick reference to problems and solutions. Please refer to the technical reference manual or consult your GSE distributor for additional information.
All 460 Series error messages are listed below in numerical order. The leading two digits will appear on the numerical portion of the display, and the message will appear on the two lines of dot matrix display. Following each message is a summation of possible causes and probable remedy.
Operational Mode Error Messages
Error Description
02 UnderLoad! Input signal less than negative full scale. Check the load cell connections. If a 4-wire load cell cable is being used, check that the sense jumpers are in place. Verify that the capacity selection P110 is correct. Use the information parameters, especially P61100 to check the setup and input signal.
03 Over-Load! Input signal is greater than 104% of positive full scale. Use same check as for underload.
04 # > Dsply Number to be displayed will not fit within 6 digits. This will not normally occur for the Gross, Net or Tare Weights but may result while displaying the accumulated totals if the amount exceeds 999,999. Clear the totals or settle for only being able to transmit the totals.
05 Zero> Max.! An attempt was made to zero out more than allowed per P118 selection. Use the [TARE] key for subtracting off container weights or if large dead load is always to be present, apply this dead load during the New Zero?
prompt during calibration to eliminate the offset.
06 Tare>F.S.! Tare entry was greater than full scale. Most likely the entered tare value was incorrect.
16 OF 20
07 Tare < 0 ! Negative tare attempted, but not allowed per P162. For autotares, the GROSS Weight must be greater than zero unless
P162 is changed to allow negative tares.
08 CheckConn. Displayed if the signal into the A/D is +/- 2 times the Full Scale signal. This is effectively taken into consideration when the information sent to the microprocessor from the A/D is +/- twice the allowable F.S. reading. ie. P110 F.S. = 100. Error message will be displayed at +/- 208 taking into consideration the 4% overload.
Setup Mode Error Messages
Error Description
10 Entry>Max! An entry was made which had more characters than allowed.
11 WRONGCODE! The incorrect access code was entered, thus preventing changes. In order to access the Setup Mode, either the proper code must be entered or [ENTER] must be pressed alone (to view selections without making changes).
12 No Mods! The Setup Mode is being accessed, but changes are prevented.
13 OutOfRange An entry made for a selection was beyond the range of valid choices.
14 Must Keyin The choice for the current parameter must be keyed in.
15 Size>3999! The size of a Custom Transmit setup has exceeded the limit.
16 CHECK JUMPR A programming operation was attempted when the program jumper is installed. Installation of this jumper prohibits programming changes.
Hardware Problem Error Messages
Error Description
17 A/D BAD! The processor has detected a problem with the A/D chip.
17 OF 20
Contact your GSE distributor.
18 BufSzMax! The accumulative total buffer size for both the TX and RX buffers of all four COMM ports is 4096 bytes. Displayed If entries to the “buffer size” parameters (P207-P208) exceed this total.
19 x06\x44\x61ta&Stop Certain combinations of protocol are not available. The protocol combination selections are in P201, P202 and P203.
This error occurs if an illegal protocol combination is selected.
Refer to the Communications chapter in the technical reference manual.
20 Deflt A/D This message appears for 1 second. It will be displayed if the
A/D calibration data gets corrupted. Contact your GSE distributor.
21 WriteNVErr Error reading data from the EEPROM. Possible U16 and U17 problem.
22 ReadNVErr Error writing data to the EEPROM. Possible U16 and U17 problem.
23 CheckNVPar Supplementary error message for above errors.
24 NVParFull! The setup being attempted requires more EEPROM than is currently installed.
Error Description
25 DefltSetup Upon power-up the indicator has not found the proper codes.
Therefore all parameters have been reset to factory default values.
26 Bad Setup The stored data has a checksum error. Check all parameters or re-load setup.
27 RE-BOOT! The indicator cannot use the EEPROM for data storage, so it is attempting to power-up again to cure the problem.
18 OF 20
28 NoRAMAVAIL The current setup requires more RAM than is currently installed. Contact your dealer or the manufacturer.
29 PIN error This message will appear on power-up or setup if the E
2 corrupted in the PIN section. Check E
2 is for problems. The access code is defaulted to the manufacturer (GSE) access code. Also check Error 11.
Calibration Error Messages
Error Description
30 F.S.>MAX! The entered calibration weight, together with the currently applied signal, indicates that the full scale signal will be greater than the allowed maximum of the indicator. Verify that correct entries have been made for the capacity, P110, and for the calibration weight.
If all appears correct, refer to the use of the information parameter
P61100, and determine the output (in mv / volt) of the connected load cell.
31 F.S.<.1mVv
32 ADD MORE!
The entered calibration weight, together with the currently applied signal, indicates that the full scale signal will be less than the allowed minimum of the indicator. Verify the proper entries for the capacity, P110, and for the calibration weight. If all appears correct, refer to the use of the information parameter, P61100 and determine the output (in mv / volt) of the connected load cell. The applied weight during calibration was less than 0.1% of capacity.
More weight than this is required. Refer to P61100 if this is incorrect.
33 ReCALReq'd The just completed calibration may not yield accurate results due to either the cal weight being less than 5% of capacity or this was the first calibration of this platform to this indicator and therefore the coarse gain was adjusted by the indicator.
34 RES> 25K! The current combination of capacity P110 and increment P111 result in a resolution greater than 25,000 graduations. This is simply a warning in case this was not intended.
Error Description
35 RES>100K! The current combination of capacity P110 and increment P111 result in a resolution greater than 100,000 graduations. This
19 OF 20
is not allowed and as soon as any key is pressed the instrument will jump back into the Setup Mode to parameter
P110 to verify the settings.
36 RES< 100! The current combination of capacity P110 and increment P111 result in a resolution less than 100 graduations. This is simply a warning in case this was not intended.
37 RES< 1!! The current combination of capacity P110 and increment P111 result in a resolution less than 1 graduation (i.e. the increment is greater than capacity). This is not allowed and as soon as any key is pressed the instrument will jump back into the
Setup Mode to parameter P110 to verify the settings.
Miscellaneous Messages
Error Description
EntryError This error message is the most commonly used. The primary causes are entering a value preceding a key (such as
[ZERO] ) which is not allowed, entering alpha data for a numeric selection, or entering a fractional value for an entry which only accepts whole numbers. Occurs in Setup Mode or an operational mode .
WhichTx#? The instrument is setup with more than one custom transmit with parameter P991 set for Prmpt (Prompt) and the [PRINT] key is pressed. The WhichTx#?
message is asking for a custom transmit number to be entered. Key in the custom transmit, then press [ENTER] . i.e. [2] [ENTER] , for custom transmit number 2.
