Introduction
This section explains the different intrinsically safe approvals and guidelines, keypad
functions, and the types of displays offered.
2.1
Hazardous Area Guidelines
The GSE Models 350 I.S. and 355 I.S. instruments are approved by FM Approvals,
ATEX and CSA as intrinsically safe for use in hazardous areas. An intrinsically safe
device has been proven through calculation and testing that it cannot produce enough
electric or thermal energy under normal or fault conditions to cause ignition of
flammable material present in the atmosphere.
The hazardous area is defined in terms of how long the hazard is present (material
presence), what type of flammable material is present (apparatus), and what maximum
temperature can be present (maximum surface temperature). Refer to Table 2.1 for
details on class, division, zone, and temperature classifications.

Class I, Division 1, Groups A, B, C & D
Class I, Division 1 locations are those in which hazardous concentrations of flammable
gases or vapors exist continuously, intermittently or periodically under normal operating
conditions. Electrical equipment for use in such locations may be ''explosion proof,''
''intrinsically safe,'' ''purged'' or otherwise protected to meet the intent of Articles 500 of
the National Electrical Code®.
Explosion proof protection consists of equipment designed to be capable of containing
an internal explosion of a specified flammable vapor-air mixture. In addition, the
equipment must operate at a safe temperature with respect to the surrounding
atmosphere.
Intrinsically safe electrical equipment and associated wiring are incapable of releasing
sufficient electrical or thermal energy to cause ignition of a specific hazardous material
under ''normal'' or ''fault'' operating conditions. Normal operation assumes maximum
supply voltage and rated environmental extremes; fault conditions assume any single
or dual independent electrical faults plus field wiring open, shorts or connections to
ground. Equipment rated as intrinsically safe is recognized by Article 500 as safe for
use in hazardous locations without special enclosures or physical protection that would
otherwise be required.
Purged systems have fresh air or an inert gas under positive pressure to exclude
ignitable quantities of flammables from the electrical equipment enclosure.
Equipment Approved for Division 1 locations shall be permitted in Division 2 locations
of the same class, group and temperature class.
Class I, Division 2, Groups A, B, C & D
Class I, Division 2 locations are those in which hazardous concentrations of
flammables exist only under unlikely conditions of operation. As such, equipment and
associated wiring which are incapable of releasing sufficient electrical and thermal
energy to ignite flammable gases or vapors under ''normal'' operation and
environmental conditions are safe to use in Class I, Division 2 locations.
Class I, Zone 0, Groups IIC, IIB & IIA
A Class I, Zone 0 location is a location (1) in which ignitable concentrations of
flammable gases or vapors are present continuously; or (2) in which ignitable
concentrations of flammable gases or vapors are present for long periods of time.
Electrical apparatus for use in such locations may be type of protection ''ia'' Intrinsic
Safety.
Class I, Zone 1, Groups IIC, IIB & IIA
A Class I, Zone 1 location is a location (1) in which ignitable concentrations of
flammable gases or vapors are likely to exist under normal operating conditions; or (2)
in which ignitable concentrations of flammable gases or vapors may exist frequently
because of repair or maintenance operations or because of leakage; or (3) in which
equipment is operated or processes are carried on, of such a nature that equipment
breakdown or faulty operations could result in the release of ignitable concentrations of
flammable gases or vapors and also cause simultaneous failure of electrical equipment
in a mode to cause the electrical equipment to become a source of ignition; or (4) that
is adjacent to a Class I, Zone 0 location from which ignitable concentrations of vapors
could be communicated, unless communication is prevented by adequate positivepressure ventilation from a source of clean air and effective safeguards against
ventilation failure are provided. Electrical apparatus for use in such locations may be
type of protection ''d'' Flameproof, ''e'' Increased Safety, ''ib'' Intrinsic Safety, ''m''
Encapsulation, ''o'' Oil Immersion, ''p'' Pressurized or ''q'' Powder-Filled.
12
Model 350 I.S. and Model 355 I.S. Service Manual
Note: Electrical apparatus Approved for use in Class I, Zone 0 locations shall be
permitted in Class I, Zone 1 locations of the same gas group and temperature class.
Class I, Zone 2, Groups IIC, IIB & IIA
A Class I, Zone 2 location is a location (1) in which ignitable concentrations of
flammable gases or vapors are not likely to occur in normal operation and if they do
occur will exist only for a short period; or (2) in which volatile flammable liquids,
flammable gases or flammable vapors are handled, processed or used, but in which
the liquids, gases or vapors normally are confined within closed containers or closed
systems from which they can escape only as a result of accidental rupture or
breakdown of the containers or system or as the result of the abnormal operation of the
equipment with which the liquids or gases are handled, processed or used; or (3) in
which ignitable concentrations of flammable gases or vapors normally are prevented
by positive mechanical ventilation, but which may become hazardous as the result of
failure or abnormal operation of the ventilation equipment; or (4) that is adjacent to a
Class I, Zone 1 location, from which ignitable concentrations of flammable gases or
vapors could be communicated, unless such communication is prevented by adequate
positive-pressure ventilation from a source of clean air and effective safeguards
against ventilation failure are provided. Electrical apparatus for use in such locations
may be type of protection ''nA'' Non-Sparking, ''nC'' Protected contacts, ''nR'' Restricted
Breathing or ''p'' Pressurized.
Note: Electrical apparatus Approved for use in Class I, Zone 0 or Zone 1 locations shall
be permitted in Class I, Zone 2 locations of the same gas group and temperature class.
Class II, Divisions 1 & 2, Groups E, F & G
Electrical equipment suitable for use in Class II locations, as defined by the National
Electrical Code®, is constructed to exclude ignitable amounts of dust from the
equipment enclosure. Approved equipment of this type has also been evaluated to
assure that hazardous surface temperatures do not exist. Equipment listed as suitable
for Class II locations is ''dust-ignition proof'' or otherwise designed to meet the intent of
Articles 500 and 502 of the National Electrical Code®.
Class III, Divisions 1 & 2
Class III locations are those which are hazardous because of the presence of ignitable
fibers or flyings. Equipment listed for installation in Class III locations is designed to
exclude the fibers and flyings from the equipment enclosure and to function without
developing excessive surface temperatures.
2.1.1 Definitions
Associated Apparatus - Apparatus, including Category ia and ib apparatus, in which
the circuits are not necessarily intrinsically safe themselves, but which affect the energy
in the intrinsically safe circuits and are relied upon to maintain intrinsic safety.
Associated electrical apparatus may be either:
a) Electrical apparatus that has an alternative type of protection for use in the
appropriate potentially flammable atmosphere; or
b) Electrical apparatus not so protected and thus not suitable for use in a potentially
flammable atmosphere.
Model 350 I.S. and Model 355 I.S. Service Manual

Control Drawing - a drawing or other document provided by the manufacturer of the
intrinsically safe or associated apparatus that details the allowed interconnections to
other circuits or apparatus. If the intrinsi-cally safe or associated apparatus is
investigated under the entity concept, the control drawing will include the applicable
electrical parameters to permit selection of apparatus for interconnection.
Entity Evaluation Concept - a method used to determine acceptable combinations of
intrinsically safe apparatus and connected associated apparatus that have not been
investigated in such combination.
Hazardous (Classification) Location - a location in which fire or explosion hazards
may exist due to an explosive atmosphere of flammable gases or vapors, flammable
liquids, combustible dust, or easily ignitable fibers or flyings.
Intrinsically Safe Circuit - a circuit in which any spark or thermal effect, produced
either normally or in specified fault conditions, is incapable, under the test conditions
prescribed in this standard, of causing ignition of a mixture of flammable or combustible
material in air in the mixture's most easily ignited concentration.
Nonincendive Circuit - a circuit, other than field wiring, in which any arc or thermal
effect produced under intended operating conditions of the equipment is not capable,
under specified test conditions, of igniting the flammable gas-air, vapor-air, or dust-air
mixture.
2.1.2 Entity Evaluation Concept
The Model 350 I.S. and 355 I.S. indicators have been approved under the entity
evaluation concept, which allows the interconnection of intrinsically safe devices in
hazardous areas even though these devices were not specifically approved in this
combination. This means that not only can the instrument be used with Avery WeighTronix FM Approved loadcells and peripherals, but they can also be used with any
manufacturer's FM Approved loadcells and peripherals provided that they have
matching entity ratings and are approved for the appropriate hazardous area.
The criteria for interconnection is that the maximum input voltage and current, which
intrinsically safe apparatus can receive and remain intrinsically safe, considering faults,
must be equal to or greater than the maximum output voltage and current levels which
can be delivered by the associated apparatus, considering faults and applicable
factors. In addition, the maximum internal capacitance and inductance of the
intrinsically safe apparatus, including interconnecting wiring, must be less than or equal
to the maximum allowed capacitance and inductance which can be safely connected
to the associated apparatus. If these criteria are met, then the combination may be
connected and remain intrinsically safe. If the specific capacitance and inductance
ratings of the wiring are unknown, use a capacitance of 60pF/ft and an inductance of
0.2uH/ft.
When connecting a Model 350 I.S. or 355 I.S. to another intrinsically safe device, the
entity ratings must be compared and satisfy the conditions shown in the following table.
2.1.3 Entity Rating Definitions
Voc or Uo - the maximum open circuit voltage that may be present at the specified
terminals
Isc or Io - the maximum short circuit current that may be present at the specified
terminals

Model 350 I.S. and Model 355 I.S. Service Manual
Ca or Co - the maximum capacitance that may be connected to the specified terminals
La or Lo - the maximum inductance that may be connected to the specified terminals
Po - the maximum output power from the specified terminals
Lo/Ro - inductance to resistance ratio that indicates the maximum inductance per ohm

Vmax or Ui - the maximum voltage that may be connected to the specified terminals
Imax or Ii - the maximum current that may be connected to the specified terminals
Ci - the capacitance present at the specified terminals
Li - the inductance present at the specified terminals
Pi - the maximum power that may be supplied to the specified terminals

Load Cell Connections
A high quality braided shield cable with 16 to 24 AWG stranded wire is recommended
for load cell or summing box connections. Route the load cell cable through the strain
relief supplied on the bottom (350 I.S.) or back (355 I.S.) of the enclosure. Either four
or six conductor cables can be used.
Do not tin the ends of the load cell wire! A terminal connection free from the
effects of vibration and oxidation can be assured only if the load cell terminals
securely grip a bare, stranded wire.
When using four conductor cables move the sense jumpers to the internal position.
When using six conductor cables move the sense jumpers to the external position.
Utilizing the (+) and (-) Sense leads of six conductor cables provides compensation for
variations in the excitation voltage due to resistance changes in the cable. See Figure
3.5 for the load cell connector.

Remote Key Connections
The Model 350 I.S. and Model 355 I.S. accommodate two remote keys connections. A
remote switch may be connected to J11 on the main board to provide remote activation
of print, tare, or zero functions. The remote switch being connected must be approved
for the appropriate hazardous area and entity parameters.
The connection for the remote switch input for remote key1 is between key 1 and GND.
Connect a second remote switch to key 2 and GND. Refer to Figure 3.7 for an
illustration of switch connections.
A two-conductor shielded cable between 28 and 20 AWG is recommended. The input
requires a contact closure from a push-button switch, a 'dry' relay contact, a photo-eye,
and a proximity sensor or other such device. A closure initiates the operation specified
at P800. A closed switch will conduct 2.2 mA.
Switch 1
Switch 2
Figure 3.7 Remote Key Connection
Do not apply an external voltage to remote key terminals! Only a contact
closure is required to activate the remote key input.
The open circuit voltage across the remote key pins is +5 VDC. A closed switch will
conduct about 0.25 mA. Therefore, a low-voltage switch with gold-plated contacts is
recommended. A Mercury-wetted switch will also work well. Minimum contact duration
of 100 ms is required. Once invoked, the selected remote key operation will not repeat
until the contact is released and closed again. See page 75 for Remote Key
Configuration.

Changing a Parameter Value
4.3.1 Selection Parameters
Selection parameters have a pre-defined list of choices to pick from. Each choice is
numbered and corresponds to a certain value. The choice number is shown to the right
of the decimal point within the parameter number. Repeatedly pressing [TARE] (Model
350 I.S.) or [ENTER] (Model 355 I.S.) while viewing a selection parameter cycles
through the available choices, or you can key in the choice number.

Choice Number
For example, parameter 200 is a selection parameter that holds the baud rate for the
serial. This is a selection parameter because a choice number between 00 and 06 must
be used. Each choice number corresponds to a different baud rate. To change the baud
rate from the default value of 9600 to 4800, perform the following steps from the Setup
Mode.
To change the baud rate from the default value of 9600 to 4800:
1.
Access parameter 200 (P200). Refer to Selecting a Parameter on page 48 on
how to access a specific parameter.

Parameter Map Details
P110 Full Scale Value (Key in)
Denotes the full scale capacity. This value should not exceed the rated capacity of the
weighing device.
P111 Division Size (Selection)
Indicates the count-by and decimal point. Pressing [ZERO] + [TARE] (Model 350 I.S.)
or [CLR] (Model 355 I.S.) will automatically select the choice closest to 10,000 divisions
without exceeding 10,000 divisions.
P112 Zero Track Aperture (Selection)
Set in terms of number of divisions. Zero tracking eliminates small weight deviations at
or near zero. Weight deviations within the selected window that have been stable for
more than one second are tracked off, maintaining a gross or net zero condition.
The sum of weight values zeroed with auto zero tracking and [ZERO] cannot exceed
the allowable zero range (P118).
To determine the proper setting in a counting application, divide the weight of the
smallest product counted by the division size (P111). Zero Track should be set to 0 (off)
for most setpoint filling operations. This prevents tracking off any product trickle at the
start of a fill process.
P114 Stability (Selection)
Stability is defined as weight fluctuations within an aperture that can be regarded as
being a stable weight. Deviations outside this aperture are considered motion, and the
motion annunciator on the front panel will light accordingly. Once the scale settles
within the stability aperture, the indicator will wait for a period of time specified by the
motion delay (P115) before the indicator is considered stable.
Print operations configured as motion delayed (P114) will not send the specified data
until the weight reflects a stable reading as designated by this setting. Certain setpoint
operations are also considered motion delayed and will not change states until a nomotion condition exists.
56
Model 350 I.S. and Model 355 I.S. Service Manual
P115 Stability Delay (Selection)
Selects the stability (motion) time delay to a resolution of 0.1 seconds. For example, an
entry of 25 will be accepted as 2.5 seconds.
P116 Filter (Selection)
Sets the indicator response time in terms of seconds. Filtering determines how quickly
the indicator will respond to changing input signals. A low filter setting speeds the
response, a higher filter setting will 'dampen' the response.
Filtering is used to filter out weight fluctuations caused by outside sources, such as
vibrations or air currents.
P117 Rate (Selection)
Specifies how often the display is updated with new data and the rate of continuous
transmits (if P210 or P230 are enabled). For example, if 0.05 is selected, the controller
will write data to the display and send continuous transmits 20 times a second.
Selections from 0.05 to 20.0 seconds are available. The actual rate may be less than
(P117). The actual rate depends on the indicator speed (P60090), the size and number
of transmits (P1000, P2000, P210, and P230), and COM ports' speed (if echo (P290)
is enabled or continuous transmits are enabled).
P118 Zero Range (Selection)
Specifies how many divisions can be zeroed in terms of a percentage of full scale
(P110). The sum of weight values zeroed through the [ZERO] key and auto zero
tracking cannot exceed this range.
A zero range of 5% is commonly used with large tank scales to avoid accidental zeroing
of a full or partially full tank.
P119 Multi-Point Linearization (Toggle)
Enable the five-point linearization feature used during load cell calibration.
P150 Units (Toggle)
Set default units to 'lb' or 'kg'. The indicator must use the default units during calibration
procedures. The default units are the displayed units upon indicator power-up.
P151 Units Button (Toggle)
When enabled, this parameter will allow the [UNITS] key to toggle the units between lb
and kg (1000g). When disabled, the indicator will show only the calibration units as
determined by P150.
P152 Third Unit (Selection)
This parameter will allow the choice of three additional units (ounces, grams or lb oz)
that may be accessed with the [UNITS] key. Only one unit will be available at a time.
The third unit can only be selected if P151 is enabled. The additional unit will be
identified by an annunciator on the display. This unit selection is not legal for trade.
Model 350 I.S. and Model 355 I.S. Service Manual
57
P161 Tare Save (Toggle)
Enabling Tare Save allows the indicator to retain the tare value in the event of power
loss. The correct net weight is restored upon power-up.
P166 Auto Tare (Toggle)
When enabled, pressing [TARE] will wait for a no-motion condition and then bring the
scale to a net zero reading. Disabling will prevent keypad tare operations.
Note that if a setpoint activation method is set to [TARE], disabling Auto Tare will also
disable the activation of that setpoint.
P167 Keyboard Tare (Toggle)
If P167 is disabled, the user cannot view tare using the select key. A numeric tare
(manually entering tare) will not be accepted and show a msg Funct" "disbl. The only
way a tare value can be entered is by using the automatic tare (press [TARE] to tare
the weight on the scale). When P167 is on, the user can view tare using the select key
(tare will follow Net). The unit will accept numeric tare. On the Model 355 I.S., users can
use the numeric keypad. On the Model 350 I.S., users can use [PRINT] and [UNITS]
to scroll in an entry.
P169 Auto Tare Clear (Toggle)
Enabling this feature will cause the current tare value to be cleared to zero every time
the indicator stabilizes within ±5 graduations of gross zero.
P171 Analog (Toggle)
Enable or disable the optional analog output module. See Analog Output Setup on
page 101 for all parameters associated with the Analog Output Module.
P179 Count (Toggle)
When enabled, the quantity mode becomes accessible via the [SELECT] key. The
quantity mode is identified by the illumination of the QTY annunciator.

Set the end character for the master indicator. Choices are 0 - 255. Default value is 3
(ETX). The choice must match the end character at P275 of the remote display (slave).
A value of 0 means that a byte with the value 0 will be sent for the character. Avoid
using values of 17 or 19 when using software flow control. The values of 17 and 19 are
Xon and Xoff codes and could cause conflict.
P296 Echo Style (Toggle)
Set the style of indicator the display will be echoed to. The choices are 300 or 60. The
300 choice is for 350, 355, 350 I.S., 355 I.S., 351, ABS 4100. Choose 60 for 460 series,
560 series and 660 series indicators.

P412 Preset Character (Toggle)
If P412 is enabled, it will add a 'P' to the beginning of the tare parameter on the display
and transmits if the last tare value was entered manually by the user (numeric entry).
P167 needs to be enabled in order to key in a tare value. A 'P' will not be added if the
last tare was performed by pressing the tare key or if the tare value is zero (even if the
zero value was manually entered by the user). The 'P' prefix stands for "Preset". When
P412 is disabled, the unit will never show 'P' before tare no matter how tare is entered.
P420 Display (Selection)
Select display control option. Choose from On, Off or Auto. The auto setting helps
conserve power for extended battery life. When the indicator display is off, the load
cell(s) are still powered.
If P420 is set to Off or selection 0, you can turn on the display by holding down the
[ZERO] key upon power up. This does not set P420 to On; it only temporarily turns on
the large VFD display in order to allow you to see what you are entering.

ID Number Entry and Printing
It is possible to enter an ID number and have the number print out on a ticket. This
mode is accessed from the weigh mode by entering [21] [SELECT]. The first six digits
of the existing ID number will be displayed. An alphanumeric ID of up to 50 characters
can be entered. At this point a new ID number can be entered or the existing number
may be cleared.
In order for the ID number to be printed, the following criteria must be met.
l
P210 or P230 must be set to ID. If the desired parameter(s) is set to another
value, the indicator will not prompt for an ID entry.
l
P213 or P233 must be set for cust. If the parameters are not set for custom,
the ID will not be printed.
l
P1000 or P2000 must contain parameter 21 (ID).
4.9.1 Enter an ID from the weigh mode:
1.
Press the [PRINT] key from the weigh mode. The display will show the current
ID number if one has been entered previously.
2.
Key in the desire ID number (numeric and/or alphanumeric) and press [TARE]
(Model 350 I.S.) or [ENTER] (Model 355 I.S.). This will print a ticket.
or
2a.
If the ID number shown is acceptable simply press [TARE] (Model 350 I.S.) or
[ENTER] (Model 355 I.S.). This will print a ticket.
4.10 Elements of a Custom Transmit
Parameters, ASCII text, and control codes are the elements of a custom transmit.
Parameters
Certain parameters related to weight, quantity, setpoints, ID and status could be sent
out of the comm port. Gross Weight, Target 1 and Quantity are examples of printable
parameters.
ASCII Text
ASCII text can be entered into a custom transmit to provide further detail of a
transaction. "P", "@" and "+" are examples of ASCII text.
Control Codes
You can custom transmit ASCII control codes to control a printing device. <CR>
(carriage return) and <FF> (form feed) are examples of control codes. When entering
a control code in a custom transmit table, use three digits preceded by a decimal point.
Example: Start of Text <STX> = 2. Key in [.002].
Model 350 I.S. and Model 355 I.S. Service Manual
67
4.10.1 Writing A Custom Transmit ASCII Text File
Any text editor may be used to construct a custom transmit (Notepad, Wordpad,
Communication Plus, etc.), but you must save the custom transmit as a text (.txt) file.
Instructions can also be sent keystroke by keystroke from a communications program.
To do so, ignore the Model 350/355 I.S. display and enter the characters in the correct
order. Figure 4.1 shows a custom transmit written in Wordpad.
4.10.2 Access Setup and Clearing Existing Custom Transmit
Every custom transmit file must start with:
1999%s%s%z%p%u%e
%c%e
This accesses the Setup Mode at the end of the existing transmit and then clears the
transmit so that a new one may be entered.
Figure 4.1 Custom Transmit File
4.10.3 Entering ASCII Text
ASCII text is defined as printable characters, including alpha-numeric as well as
punctuation and symbols. See Table 4.1 for a complete listing of ASCII characters.
ASCII text can be entered directly into a custom transmit with a %e (enter command).
For example, Joe's Fertilizer Plant%e.
68
Model 350 I.S. and Model 355 I.S. Service Manual
4.10.4 Entering ASCII Control Codes
Some ASCII characters are known as control codes, non-printable characters that
instruct a printing device to perform certain functions. For example, a carriage return
<CR> forces a printer to move the print head to the left-most position of the current line.
A line feed <LF> forces the print head to move down one line. Enter control codes with
a decimal point, a 3-digit ASCII code, and a %e. For example, .013%e.

4.16.1 Activation Methods
Setpoint activation for Fill, Batch, Discharge, and Both can be initiated in one of four
ways: Tare, Remote, Auto and Start key (355 I.S. only). Check-weigh operations have
no start function but there are two methods of restarting. See parameter 5004 on page
63 for more details. Independent setpoint operations are limited to Above or Below
activation. The Model 350 I.S. and Model 355 I.S. setpoint option board may be
connected in-series with a larger automated control system or a manually activated
switching device. A foot switch, a two-hand safety station, or other permissive-start
devices may be used for safety or system compatibility.
Activation
Method (P5003)
Description
Tare Operation
The [TARE] activates the setpoint. It waits for a no-motion condition, then
tares scale to net zero. The appropriate setpoint is then activated.
Remote Key 1
(START key)
355 I.S. only
The [START] key activates the setpoint. The remote key function (assigned
at P800) is over-ridden. A setpoint and P5003 must be enabled for the start
key to operate.
Remote Key 2
(STOP key)
355 I.S. only
The [STOP] key activates the setpoint. The remote key function (assigned at
P801) is over-ridden. A setpoint and P5002 must be enabled for the start key
to operate.
Auto-Start
Automatically activates the setpoint after motion ceases.
4.16.2 Pre-Acts
Pre-Acts are control actions prior to reaching a desired target value. Necessary to
prevent over-filling due to product flow rate, relay and valve response time and product
suspension, Pre-Acts compensate for other system variables affect how much more
product reaches the weighing device after the indicator has deactivated a setpoint.
Pre-act 1
Used in dual-speed applications, pre-act 1 specifies when the Model 350/355 I.S.
should switch from fast-fill to slow-fill, allowing the system to perform the bulk of a filling
operation as quickly as possible before switching to a more manageable dribble mode
for final cutoff. When using a single-speed device, set pre-act 1 to 0.
Pre-act 2
Specifies the weight where the final cutoff should occur, enabling the Model 350/355
I.S. to compensate for a dispensing control's closure time and account for free-fall
material. Free-fall is the amount of product that has passed the point of the dispensing
control yet not yet reached the weighing device.
78
Model 350 I.S. and Model 355 I.S. Service Manual
Pre-act values are entered in terms of the amount of product that would over-fill or how
early to close the control device. For instance, after repeated tests, a system
consistently over-fills by .5 lbs. This is the value that should be entered as the pre-act.
The Model 350/355 I.S. would then deactivate the setpoint .5 lbs. less than the desired
final target value.

Final fill valve closes at 399.5 lbs.
4.16.3 Learn Feature
The Model 350/355 I.S. can learn optimal pre-act values. When enabled, the learn
feature will automatically adjust the final cutoff value based on an analysis of the five
previous fills, helping achieve a final target by compensating for product viscosity,
changes in plant air pressures, sticky valves, etc. For each cycle, the prior five final
weights are analyzed and a new pre-act value is calculated.
4.16.4 Pause Feature
The Model 350/355 I.S. can pause setpoint operations. This is useful to provide a
pause for mid-cycle operator breaks, mechanical adjustments, etc.

4.20 Discharge
The discharge program is designed for single-speed or dual-speed dispensing of
product from a larger weigh vessel. Discharge is a loss-in-weight application similar in
operation to the fill program. When a discharge is initiated, the scale automatically tares
and comes to a net zero weight. The appropriate setpoints are activated and material
is discharged until the decreasing net weight reaches the desired target value. Free
falling product can be accounted for with the use of pre-act values (PA1 - PA3). This

4.25.1 Setpoint Activation
Independent Setpoints can be activated when the gross weight, net weight or quantity
(if counting is enabled) is above or below a target value. When an independent setpoint
is set to Activate Above, the setpoint will activate when the selected mode (gross, net
or quantity) is equal to or above the target. When set to Activate Below, the selected
mode must actually be below the target.

4.26 Bargraph Setup (LCD)
A bargraph display is available for the ChecP, Fill, Batch, Dschg, Both and ChecA
setpoint modes of operation. To enable the bargraph, refer to parameter P5011 (SPbar)
in the Parameter Map section beginning on page 64. To weight each segment of the
bargraph refer to parameter P5012 (bArPc) in the Parameter Map section beginning on
page 64.
4.26.1 Scaling For "Bars" (Bargraph Arrows)
If the first bar turns off at the specified percentage (set at P5012) of the low limit, and
the last bar turns off at the low limit, then the difference will be divided by 8 to determine
the number of lbs per bar. At less than 5 grads, the entire graph is off.

NOTE: (bargraph for filling and emptying modes)
For modes other than check-weighing, the bars will be on only while the setpoints are
on and during the "Done" at the end of a fill.
The bar weights will be calculated similar to the check-weigh modes of operation
stated above for filling, batching, etc., except that the percentage will be based on the
actual target, rather than the low-limit value (see the equation below). The operation
for emptying (and the emptying portion of 'both') will be the same except that the
weight will be going negative while the left side bars are turning off.
Although the setpoint annunciators are not motion-inhibited, the setpoint relay outputs
will not activate until a no-motion condition exists.

Analog calibration values can be entered into the Model 350 I.S. and Model 355 I.S. by
keying in the data in the left-hand column, beginning at the line starting with "61200…",
replacing the "%s" character pairs with the [SELECT] key and "%e" with the [TARE]
(350 I.S.) or [ENTER] (355 I.S.) key. The line with the "%c" is not adjustable and cannot
be entered.
You can adjust the included factory recommended offset and gain values to precisely
configure the system being connected to these outputs. Once the initial factory values
have been entered, pressing the [TARE] (350 I.S.) or [ENTER] (355 I.S.) key will cause
the count value to increase one count, and pressing the [PRINT] + [UNITS] keys will
decrement the count value by one count. All changes made are updated "live" to aid in
calibrating a specific device to the analog option board output. Holding down the key(s)
will repeat the increment/decrement action.

Since 7.166 v is less than 8 v (per P175), the output signal is not restricted and would
be 7.166 v.
If a current output is selected, the output is a milli-amp current where 0 volts
corresponds to either 0 mA or mA (as per P177) and 10 volts would translate to 20 mA.
Values in between would be scaled proportionately:
(20mA -4mA) x 7.166

Analog signal resolution: the output is the result of a 16 bit conversion resulting in a
resolution of 1 part in 65535 or 10 / 65535 = 0.00015 v.
4.28 Remote Display Configuration
The remote display function allows a master indicator (350 I.S. or 355 I.S.) to be
echoed to another indicator (350 I.S., 355 I.S., 355) and be used in a remote location.
There are certain parameters that must be set in order to have the master and slave
indicators communicate together. Refer to the section below to configure the master
and remote (slave) indicators.
The master does not transmit any information to the hub unless there is something
new to report such as a change in weight, keypress, etc
Model 350 I.S. and Model 355 I.S. Service Manual
107
4.28.1 Master to Remote (Slave) Configuration
The remote indicator will receive continuous transmission from the master indicator. It
is necessary to setup the protocol parameters in both indicators so they match in order
to coordinate the transmission. See table below for the common protocol parameters.
A remote indicator will not show the bargraph even if it is a LCD display.

4.28.6 Display Capture Utility
The Display Capture Utility sends the current display information out of the one of the
available comm ports when the one of the two extended ASCII character represented
by decimal 149 (hex: 95h) or decimal 150 (hex: 96h) are received through the comm
port. The previous characters can be used when the comm port is set to 8 data bits.
For 7 data bits comm port, %[Ctrl-U] or %[Ctrl-V] can be used to replace 149 or 150
respectively. Upon receiving decimal 149, the Display Capture Utility sends the current
display information out of comm port 1. Upon receiving decimal 150, the Display
Capture Utility sends the current display information out of comm port 2. Entering a
decimal 149 from a computer keyboard can be accomplished by turning on the Num
Lock and holding down the ALT key while typing the desired decimal number on the
keyboard keypad (for example, <Alt>149).
The Display Capture Utility must have NTEP (P440) disabled in order to function.
Example #1
The scale is in the weigh mode with the gross weight displayed (for example, 15.00).
Input: The extended ASCII character represented by decimal 149 (hex: 95h) is
received through any comm port.
Output: "15.00 lb
Gross
" is sent out comm port 1.
Example #2
The scale is in setup at P110 Full Scale.
Input: The extended ASCII character represented by decimal 150 (hex: 96h) is
received through any comm port.
Output: "P110
116
F.S.
100.00
" is sent out comm port 2.

5.2.7 Multi-Point Linearization
If the load cell signal input to the indicator has good repeatability and stability, then
using multi-point linearization during calibration may significantly improve the ultimate
accuracy of the data displayed by the indicator. Parameter 119 (P119) enables or
disables this feature. Initially, the same basic procedures as a normal calibration are
used to perform a multi-point linearization. All of the prompts provided will be exactly
the same as a standard calibration for each cal point up to the Cal ~ Good? prompt.
If items are consistantly being weighed on either the high or low end of the cell capacity,
the points of calibration can be skewed to either end of the spectrum. Multi-point
linearization can compensate for a cell that is non-linear. Refer to page 117 for the
instructions on how to enter the calibration mode.

Legal for Trade
The Model 350/355 I.S. default parameter setup does not ensure compliance with
legal-for-trade installations as mandated by local weights and measures authorities.
This chapter contains information on NTEP and OIML regulations, sealing and audit
trails, and other requirements.
Since legal-for-trade requirements may vary, you must ensure that the Model 350/355
I.S. is installed in accordance with all local regulations.
6.1
NTEP Requirements
The National Type Evaluation Program (NTEP) is a widely accepted weights and
measures standard in the United States, with most states abiding by some or all of the
NTEP requirements. A complete list of these regulations is available in the "Handbook
44" publication distributed by the National Institute of Standards and Technology
(NIST). For more information visit http://www.nist.gov.
In order to configure the Model 350/355 I.S. to comply with NTEP requirements,
parameter P440-rstrc (restrict) must be enabled. This ensures the following:
l
Serial data will not be received while in the Setup Mode.
l
Received alpha characters will not be displayed.
l
Numeric tare entries cannot be received through the serial port.
l
Pressing [TARE] with a gross weight of zero (0) will not automatically switch
to the net mode.
l
Negative tare values are not accepted.
l
Tare rounding is enforced.
l
When the tare value is zero, the net mode is not selectable.
Where applicable, enabling the restrict parameter will over-ride the current setting of
other parameters.
If the counting feature is enabled, NTEP requires a label on the front of the indicator
stating "The counting feature is not legal for trade".
Most NTEP requirements will also apply. See the Other Requirements section for
additional considerations.
6.2
OMIL Requirements
The International Organization of Legal Metrology is an inter-governmental body which
harmonizes the national metrology regulations of its world wide members. A list of
regulation publications may be obtained from the Bureau International de Métrologie
Légale (BIML) in Paris, France.
In order to configure the Model 350 I.S. to comply with OIML requirements, parameter
P410-Euro must be enabled. Doing so will ensure the following:
Model 350 I.S. and Model 355 I.S. Service Manual
127
6.3
l
An over-load condition will result when the gross weight exceeds nine
graduations over the full scale capacity.
l
Full scale capacity is always referenced from the last zero calibration
reference, not the last zero acquired by pressing [ZERO].
Other Requirements
Several parameters must be considered on an individual basis as their configuration
may vary with different applications. These parameters include, but are not limited to:

Sealing and Audit Trails
Most legal-for-trade installations will require the Model 350/355 I.S. 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 of tampering.
The Model 350/355 I.S. has two types of sealing provisions; a physical seal and a
three-event audit trail counter. Check with your local weights and measures authority
to determine your requirements.

Model 350 I.S. and Model 355 I.S. Service Manual
6.4.1 Physical Seal
The most common sealing method is a lead-wire seal. The Model 350 I.S. and Model
355 I.S. provide an easy means of applying this type of seal as shown in Figure 6.2.
Before applying a wire seal, move the program jumper to the 'NO' position as shown in
Figure 6.1. This will prevent access to the Setup and Calibration Modes.

A/D Calibration Procedure
The Model 350/355 I.S. Analog-to-Digital Converter (A/D) is calibrated at the factory to
ensure a stable, linear response to the load cell signal. This calibration procedure
calculates critical values that are permanently stored in parameters P61110 - P61121.
The A/D calibration should not be confused with the standard weight calibration. It
should never be necessary to recalibrate the A/D. However, if the values stored at
parameters P61110 - P61121 appear to be reset to 0.00000 and/or 1.00000, then A/D
recalibration is necessary. Contact Avery Weigh-Tronix or your local authorized Avery
Weigh-Tronix distributor for more information on this procedure.
