Display
The Model 350 and Model 355 indicators are available with either a six digit, 7-segment green LED display, a six digit, 7-segment black LCD display or a 7-segment backlit LCD display. The Model 350 and Model 355 will display alphanumeric data, but due to the nature of 7-segment LEDs/LCD and the limitation of six digits, some information is abbreviated.
All segments and annunciators are illuminated for a brief display test upon power up. The current gross weight is then displayed in default units.
LED D ISPLAY
The LED display is a six digit, 7-segment bright green LED screen with 12 annunciators to show weight and status information. The SP1, SP2, and SP3 annunciators are red, green, and yellow. Also there is an annunciator for a third unit under kg. Place the third unit label above the third annunciator
(the third unit is available on both the LED and LCD displays). See page 53 for third unit setup.

A high quality braided shield cable with 16 to 24 AWG stranded wire is recommended for load cell or summing box connections. Secure the cable by the cable tie on the die cast model, or route it through the strain relief supplied on the back of the internal power supply models (see Figure 12 ). Either four or six conductor cables can be used.

350/355 Technical Reference
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, (+ Excitation) must be connected together with (+ Sense), and (-
Excitation) must be connected together with (- Sense) on the Model 350 die cast.
Sense jumpers are standard on the Model 350/355 Stainless Steel (E3 and E4). Utilizing the (+) and (-) Sense leads of six conductor cables provides compensation for variations in the excitation voltage due to resistance changes in the cable.

Before connecting to the serial port, consideration should be given to the communication protocol and to any remote key requirements. For information on remote key operation, refer to Remote Key Operation on page
97. Use Table 1: Serial Port Connections to determine proper wiring to the communication port.
Communication connections are made through the DB9 male connector on the rear of the enclosure or a pigtailed cable through a strain relief (internal power supply model on J6 comm connector). The cable should be 20 to 28 AWG with a braided or foil shield for either model type. For maximum noise immunity on the die cast model, use a mating DB9 connector with a metal hood and a braided shield cable. Ensure that the braid makes good connection with the hood. The maximum recommended cable length is 50 feet (15

A remote key may be connected to the Model 350/355 communication port to provide remote activation of print, tare, or zero functions.
The connection for the remote key input is between pin 1 and pin 6 of the DB9 communication port connector (see Figure 15 for die cast , Figure 14 for stainless). 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.
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. A 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.

Setpoint Card Connections
Using one of the software setpoint configurations (see General Setpoint Setup on page 70) in conjunction with the setpoint option board gives the Model 350/355 the ability to directly control external devices such as valves, relays, actuators, etc.
There are up to three setpoint outputs available. The activation and deactivation is controlled by the setpoint configuration. The outputs are capable of driving up to 20-280VAC & 2 Amp at 3-60VDC @ 1A. The solid state relays are normally open (NO) contacts.
See General Setpoint Setup on page 70 for setpoint software configuration details.
The Model 350/355 contains components which could be damaged by Electrostatic Discharge
(ESD) if serviced improperly. Use proper ESD precautions (wear a wrist strap connected to ground, use grounded work stations, etc.) when opening the enclosure.
High voltages may exist within the enclosure! To prevent the risk of electrical shock, ALWAYS unplug the Model 350/355 when opening the enclosure. Installation and servicing of the Model
350/355 should be performed by authorized and qualified service personnel only.
Never connect or disconnect option board cables while the indicator is powered. Doing so may result in circuit board damage.
To install the Setpoint Control Module (350 die cast):
1.
Open the indicator.
Remove the four screws from the back of the unit. It may help to remove the swivel bracket, if installed.
2.
Place the back of the indicator, open side down, on a firm surface. Using a hammer and screwdriver, remove the appropriate knock-out.
It helps to place the screwdriver tip on the knockout pad, rather than in the groove. The knock-outs do not require much force to remove. If only installing one option, the left knock-out (as viewed from the rear) should be removed. A small file may be used to remove any burrs.
3.
Flip the back cover over and place the Setpoint Control Module, component side down, over the four mounting holes. Install four
10mm screws to a minimum of 8 in/lb of torque.
Be sure the cable is already attached before installing the card.
Also be sure the cable is attached to the left-most connector (as viewed from the component side of the option board). The second connector is for ‘daisy-chaining’ another option card. The screws used to mount the option card are self-tapping and will require added torque when first installed. Figure 25: Option Board
Installation (Die Cast Model 350)
4.
Attach the loose end of the cable to the serial I/O connector (J7) on the main board or the open connector of a previously installed option card.
J7 is a 10-pin polarized connector. Be sure the cable is not twisted when installed. If this is a second option card, route the cable to the open connector of the first option card.
5.
Reinstall the back cover. Tighten the four screws to a minimum of 8 in/lb torque.
Be sure to avoid ‘pinching’ the cable between the housing halves. Affix all appropriate labels to the back of the indicator.

Installing jumpers 1, 2 and 4 on the RS-485 option board electrically connects pin RX B(+) to pin TX B(+), and pin RX A(-) to pin TX A(-) on the option board. This effectively provides two + and two - pin connections, enabling easy connection of network lines in parallel from device to device without having to position two wires into the same lever socket. A B(+) line from each device on the network should be connected in parallel to the next device on the network. This is also true for all A(-) lines.
The units inside the two end-points of the network loop will utilize both A(-) pin connections and both B(+) pin connections. The units at the end-points of the network will utilize only one A(-) pin connection and one B
(+) pin connection.

Removing jumpers 1, 2 and 4 on the RS-485 option board requires that the transmit and receive lines be wired independently of one another. The RX B(+) and RX A(-) receive lines must be wired in parallel to the next device’s RX B(+) and RX A(-) receive lines , and the TX B(+) and TX A (-) transmit lines must be wired in parallel to the next device’s TX B(+) and TX A(-) transmit lines.
In order to connect network lines in parallel from device to device it is necessary to position two wires into the same lever socket. This requires that the wire used to build the network be 24 AWG or smaller to allow both wires to fit into the same lever socket.

20 mA Current Loop Option
The 20mA option will convert the communication port of the indicator from RS-232 to 20 mA current loop.
This is a digital communication signal and should not be confused with a 4 to 20-mA (or 0-20 mA) which is an analog output signal. The intended use is primarily printers and scoreboard displays.
This option will mount into the socket for the comm port RS-232 chip on the main board. This option will exclude the use of the RS-485 option board. (I.e. only the RS-485 OR the 20 mA option can be installed into an indicator). Three snap-in stand-offs are included with the board to secure it to the main board beneath it.
To Install the 20mA Current Loop Option:
1.
Open the indicator in order to gain access to the main board.
2.
Remove the RS232 IC from its socket. (See table for location)
3.
Remove the white wire jumper. (See table for location)

The on/off switch for the Model 350 die cast is a rocker-type switch that mounts in the center rectangular hole punch-out. The on/off switch for the Model 350/355 stainless is a toggle-type (washdown type) switch that replaces one of the available enclosure strain reliefs. The switch is soldered to the board (die cast) or on a cable (stainless).
The Model 350/355 will immediately switch to battery operation when AC power is interrupted if the switch is in the ON position. Placing the switch in the OFF position prevents the battery from running down when AC power is removed. The battery will be charged whenever there is AC power to the Model 350/355, regardless of the switch position.

The 24350B-121B0 kit included a stainless steel washer and a rubber washer to allow mounting of the
ON/OFF switch in 44-25-34840 revision.
The switch was mounted in one of the holes for a PG9 size strain relief. The washers were used because the switch barrel diameter was much smaller than the hole diameter. The revision B enclosures have a PG7 size strain relief hole which allows mounting of the switch without the washers. Current Model 350/355 production has switched to the revision B enclosures. The washers are not included in the version 2 option kits for this reason. If you are retrofitting an older Model 350/355 Stainless Steel Indicator, please contact your sales representative to get one each of the following GSE part numbers:

NSTALLATION
The HCS cable is glass fiber in a round jacket. The cable allows a distance of 1000 feet maximum. Since
HCS fiber-optic cable is not easily fabricated on site and tooling is too expensive for on time use.
Prefabricated cables in 100 feet increments can be purchased from GSE. The cable comes ready to install with connecting ends and a strain relief for the enclosure.
1.
Remove the strain relief to the right of the load cell strain relief.
2.
Insert the strain relief of the HCS cable through the strain relief hole of the enclosure.
3.
Slide the strain relief nut over the HCS cable and screw it to the strain relief. Tighten nut with a 7/8” socket or wrench.
4.
Plug fiber connectors into connectors on fiber-optic board.

Changing a Parameter Value
S ELECTION P ARAMETERS
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 1 (Model 350) or ( (Model 355) while viewing a selection parameter cycles through the available choices, or you can key in the choice number.
P 200.00
Indicates Parameter Parameter 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.

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 + 1 (Model 350) or (Model 355) 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 " cannot exceed the allowable zero range (P118).
Truck scales commonly use zero tracking to compensate for snow fall. 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.
(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 no-motion condition exists.

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.
(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.
(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 " 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.
(Toggle)
Enable the five-point linearization feature used during load cell calibartion.
(Toggle)
Set default units to ‘lb’ or ‘kg’. The indicator must use the default units during calibration procedures
( see Chapter 4) . The default units are the displayed units upon indicator power-up.
When enabled, this parameter will allow 2 to toggle the units between ‘lb’ and ‘kg’ (1000g).
When disabled, the indicator will show only the calibration units as determined by P150.
Unit
This parameter will allow the choice of three additional units (ounces, grams or lb oz) that may be accessed with the 2 key. Only one unit will be available at a time. The third unit can only be selected if P151 is enabled. The third unit will be identified by an annunciator on the display. This unit selection is not legal for trade.
P161 Tare Save (Toggle)
Enabling Tare Save allows the indicator to retain the tare value in the event of power loss. The correct tare and net weights are restored upon power-up .
When enabled, pressing # will wait for a no-motion condition and then bring the scale to a net zero reading. Disabling will prevent keypad tare operations.
53
Chapter 4
Note that if a setpoint activation method is set to 1 , disabling Auto Tare will also disable the activation of that setpoint.
P167 Keyboard Tare (Toggle)
If P167 is disabled, then the user cannot view tare using the select key. Also, it will block numeric tare (manually entering tare) and show a msg "Funct" "disbl". Only way you can tare is using the automatic tare (press 1 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, users can use the numeric keypad. On the Model 350, users can use and 2 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.

350/355 Technical Reference
Custom Transmit
The serial output of the Model 350/355 can be configured for a custom application such as a remote display format, a customized computer program format, or a customized ticket format. The custom transmit must be designed in a computer-transmittable ASCII text file and is loaded into the indicator’s serial port via a computer. P213 or P233 must be set to 0 to select the custom transmit format for transmission.
E LEMENTS OF A C USTOM T RANSMIT
Parameters, ASCII text, and control codes are the elements of a custom transmit.
Parameters
Certain parameters related to weight, quantity, setpoints and status can 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 .
W RITING A CUSTOM TRANSMIT ASCII TEXT FILE
Any text editor may be used to construct a custom transmit (Notepad, Wordpad, 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 display and enter the characters in the correct order. Figure 37 shows a custom transmit written in Wordpad.
A CCESSING S ETUP AND C LEARING E XISTING C USTOM T RANSMIT
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.

E NTERING ASCII T EXT
ASCII text is defined as printable characters, including alpha-numerics as well as punctuation and symbols.
See Table 8 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 .
E NTERING ASCII C ONTROL C ODES
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 .

The analog output calibration procedure establishes explicit zero and full scale values for each of the three analog output modes: 0 – 10V, 0 – 20 mA and 4- 20 mA. There are five adjustment values for the analog option, located at the information parameters P61200 through P61205, that allow the zero and full scale output of each mode to be adjusted to exact values. This allows the analog option to be configured to match the needs of the system being connected to its outputs.
The calibration values for each of these modes has been determined at the factory. These values are provided on paper with each board to make calibrating the analog option a simple process. Each analog option board can be identified by its serial number, which is entered in the unit during the calibration process.

Each program utilizes the three annunciators located to the left of the main display to give a visual status of the setpoint. A setpoint option board may be installed to allow control of an external device (see Setpoint
Card Connections on page 26).
A CTIVATION M ETHODS (G ENERAL )
Setpoint activation for Fill, Batch, Discharge, Both, and Batch2 can be initiated in one of three ways: Tare,
Remote or Auto. Check-weigh operations have no start function. Independent setpoint operations are limited to Above or Below activation. The Model 350 and Model 355 setpoint option board may be connected inseries with a larger automated control system or a manually activated switching device. A foot switch, a twohand safety station, or other permissive-start devices may be used for safety or system compatibility.

Tare
Operation

350/355 Technical Reference
P RE ACTS (G ENERAL )
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 and 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 350/355 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 350/355 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.
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 350/355 would then deactivate the setpoint .5 lbs. less than the desired final target value.
Example :
Parameter Setting
Target = 400 lbs.
Pre-Act 1 = 28
Pre-Act 2 = .5
Actual Cutoff
Value
Comments
400 – 28 = 372
Desired final weight.
Switch to slow feed at 372 lbs.
400 – 0.5 = 399.5 Final fill valve closes at 399.5 lbs.
L EARN F EATURE (G ENERAL )
The 350/355 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.
P AUSE F EATURE (G ENERAL )
The 350/355 can pause setpoint operations. This is useful as a safety device, for mid-cycle operator breaks, mechanical adjustments, etc.
When invoked, Pause deactivates all setpoints. The display will show: Tare= ~ Abort . Pressing # will abort the current cycle; any other keypress will resume the cycle. The Pause feature has four settings:

When a setpoint operation is configured from the Setup Mode, certain parameters are made available in the
Weigh Mode. Pressing !
cycles through available modes (Gross, Net, Quantity, Targ 1, etc.).
When viewing a setpoint-related parameter from the Weigh Mode, # takes on a special function. Data keyed in prior to # will be displayed as the new setpoint parameter value. Pressing # alone will advance to the first subset for the current setpoint parameter. Pre-acts and tolerances are subsets of their respective target values.
A negative target value many be entered for the independent setpoints only. To enter the negative sign press then + 2 (Model 350) or # (Model 355) . A negative sign will be displayed. Press # to continue with the entry
Programs that involve a discharge cycle are loss-in-weight type applications. Any target or pre-act values for these programs should be entered as positive numbers. The 350/355 will automatically interpret these values as negative.

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.

Target Deviation Check-Weighing
The target deviation method uses a target value in which the upper and lower tolerances are deviated from the target. The upper and lower tolerances are fixed values. The accept window is varied by adding the high tolerance to the target and subtracting the low tolerance from the target. This feature is commonly used in check-weigh applications. The desired target may be based on gross weight, net weight or quantity (if counting is enabled). The annunciators will light on the indicator display or physical setpoints can be added.

Batch 2
The batch 2 program is used for batching up to three separate items without using preact values. Ingredients
1 through 3 use setpoints 1 through 3 respectively. Ingredients are batched one at a time. The target values can only be set from the weigh mode by pressing the [SELECT] key.
After a batch is run all target values will be set back to 0. The target values will be set to 0 after accessing the setup mode or if power is cycled. If a new batch is started when all target values are set to 0 an error message “No Targ” will be displayed.

S ETUP
The Model 350/355 controller supports address recognition, which allows a single master device to communicate with up to 250 distinct slave controllers. P250 must be enabled in order to gain access to
P251. Enabling P250 by itself only causes the RTS line to become a driver enable for the RS-485 network option. Changing the P251 address to a value of 4 – 254 enables the network address recognition receive feature (i.e. networking).
O PERATION
When P251 is enabled by choosing a valid address, the Model 350/355 will ignore all data it receives until an <STX> character is followed immediately by a character that matches the address defined by setup parameter P251. If these two conditions are met then the Model 350/355 will process all subsequent data until the end of block character, <ETX>, is received, signaling the end of the transmission. The receive routine of the Model 350/355 then resets to look for the <STX> character again.
The data packet format recognized by the Model 350/355 is defined as follows:
<STX><ADDRESS><DATA><DATA><DATA><DATA>…<ETX>
Refer to Table 6: ASCII / HEXADECIMAL CONVERSION CHART on page 63 for <STX > and <ETX> ASCII codes. The address is a single byte decimal value (4 – 254). The <DATA> can be any information recognized by the Model 350/355, including direct commands – such as a %p (Print). This would direct the addressed unit to send its print transmission defined at P213 over the network.
If the received address character does not match P251 then all of the subsequent data is ignored until the next start of packet character,<STX>, is received.
An address of 0 at P251 will cause the Model 350/355 to process all received data.
N ETWORK P ROTOCOL
The protocol settings for the RS-485 network option board are the same as the protocol settings for RS-232.
These settings are found starting at parameter P200. All devices connected to the network must have matching protocol settings.

350/355 Technical Reference
Upgrade Indicator Firmware
The Model 350 and Model 355 have flash memory on the main board where the parameters are stored. It is possible to update the firmware simply by using a computer. The firmware is loaded into a flash memory IC.
This allows for ease in loading firmware updates.
The flash memory on the main processor is only rated to be reflashed up to 10 times under extreme industrial and temperature conditions.
P REPARE FOR UPGRADE
Before the indicator firmware can be updated, the procedure below must be followed. A computer with a serial port or USB port is required for loading a flash file. If you are using a USB port, a USB to serial converter is necessary.
1.
Connect the communication cable from the computer to comm. 1 of the Model 350 or Model 355.
2.
Open a communications program or terminal window program (such as Communication Plus) on the computer.
3.
Set the protocol of the indicator to be 9600 baud, 1 stop bit, no parity.
4.
Go to parameter 65020 (re-flash) by keying in [65020] [SELECT] and press [TARE] (Model 350) or
[ENTER] (Model 355). Press [TARE] (Model 350) or [ENTER] (Model 355) at the “ARE YOU SURE
? prompt. Press [TARE] (Model 350) or [ENTER] (Model 355) at the Enter = Flash prompt.
~ Or ~
Unplug the indicator and move Reflash jumper (E2) from NORMAL to REFLASH.
5.
The terminal program should show:

6.
Typically the default baud rate on the computer will be 9600. The programming time at 9600 baud is about 6 minutes. At 38400 baud the programming time is about one minute and a half. At 57600 baud the programming time is about one minute. Set the indicator baud rate in the terminal software to the desired baud rate by entering c from the computer keyboard. Set the baud rate of the terminal program to match the baud rate chosen for the indicator.

The current flash file must be erased. Enter an a from the computer keyboard. When finished the menu choices will be replicated.
2.
To program flash, enter a b from the computer keyboard. Open the flash file from your terminal window and send it to the indicator. After the file loads the menu choices will be replicated.
3.
To end the flash process, enter a d from the computer keyboard to quit. The indicator will restart.
4.
If the Reflash jumper (E2) was set to REFLASH, unplug the indicator and return the jumper to the
NORMAL position.
NOTE: In order to enable the Model 355 keypad you must cycle power and hold the ( key on power up.
NOTE: If Ch#### is displayed after reflashing then the reflash failed. Use the reflash jumper to force reentry into reflash menu and reprogram again.

Remote Display Configuration
The remote display function allows a master indicator (350 or 355) to be echoed to another indicator (350
Series or 60 Series) 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.
M ASTER TO R EMOTE (S LAVE ) C ONFIGURATION
The remote indicator will receive continuous transmission from the master indicator and echo the master indicators display. The keys of both indicators will operate as normal.
It is necessary to setup the protocol parameters in both indicators so they match in order to coordinate the transmission. See Table 26 for the common protocol parameters. A remote indicator will not show the bargraph even if it is a LCD display.

When set for Custom , the master indicator will send customized information to be displayed on the remote indicator. A parameter or text data may be transmitted to the remote indicator on a continual or “on demand” basis.
Set P271 for Custom and set all other remote display parameters (refer to Table 27). Configure the parameters in the master indicator (refer to Setup Master Indicator on page 100). Make sure that the wiring connections between the master and remote indicators are correct (refer to on page 15. Follow the instructions below for configuring the master indicator.
1. Turn echo off at P290.
2. Set the transmit to be continuous at P210 (port 1) or P230 (port 2). This is the port going to the remote indicator.
3. Program custom transmit in the master indicator at P1000 (port 1) or P2000 (port 2). See the example below for instructions on programming a custom transmit.
If time out is enabled (P270), then the transmit should be set for continuous at P210 or P230 and have stability disabled at P212 or P232
Example:
The master indicator will be active and the Net weight will be displayed on the remote indicator. The net and lb annunciators will illuminate. The codes for the annunciators will be entered as they are control codes (see

Control (Hazardous Area) to Hub (Safe Area)
Configuration
In order to use setpoints or analog output modules they must be located in the safe area. These modules will be installed in the safe area hub. Refer to Analog card connections or Setpoint card connections on page 19 for option installation instructions. The control indicator will be in the hazardous area and where the load cell(s) will be connected. The control and hub indicators will communicate via fiber optic cable. Refer to fiber optic iinterface on page 40 for installation instructions.
Use the following instructions to setup the control and hub indicators. Once a control or hub indicator is chosen at P260, the protocol and interactive parameters are automatically set up. See Table 29 for the default parameters of the control and hub . The setpoint and analog output parameters are only set in the control indicator (refer to Setpoint Setup on page 70 or Analog Output Setup on page 67). The hub indicator will echo the control indicator.
Make sure the controller and hub are connected with the fiber-optic kit and fiber-optic cable. Setup the hub indicator first and either cycle power or enter then exit the setup mode. This will synchronize P176, P177,
P61200 – P61205.

False Zero calibrates the Model 350/355 without removing the current gross weight. This is particularly useful in tank weighing applications where it may be both time consuming and costly to completely empty the tank. This operation is achieved by establishing a false (temporary zero) zero reference. Test weights may then be added to verify calibration.
The zero reference determined during the last calibration is not affected.

Cal Reset may be necessary when an over-load or under-load condition exists, preventing the completion of the calibration process. Calibration Reset adjusts the zero and gain factors of the A/D amplifier to factory default values for maximum sensitivity.
After performing a calibration reset, a complete recalibration is required. The effects of a calibration reset do not take effect until the Model 350/355 recalibrated and calibration information has been saved.
If Code 02 (under-load) or Code 03 (over-load) is displayed during calibration, press to perform a calibration reset.

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 109 for the instructions on how to enter the calibration mode.

Chapter 6: Legal for Trade
The Model 350/355 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 installed in accordance with all local regulations.
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, call (301) 975-3058, or visit http://www.nist.gov
.
The Model 350/355 NTEP Certificate of Conformance (C.O.C.) is 98-092A2.
In order to configure the Model 350 to comply with NTEP requirements, parameter P440-rstrc ( restrict ) must be enabled. This ensures the following:
• Serial data will not be received while in the Setup Mode.
• Received alpha characters will not be displayed.
• Numeric tare entries cannot be received through the serial port.
• Pressing # with a gross weight of zero (0) or keying in a tare value of zero (0) will not automatically switch to the net mode.
• Negative tare values are not accepted.
• Tare rounding is enforced.
• 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” . See Other Requirements on page 124 for other application specific considerations.
NTEP Panel Mount Requirements
In addition to all other NTEP requirements, the serial number of a panel mounted unit must be visible from the outside front of the controller. The serial number on the Model 350 rear label must be engraved in the space provided on the panel mount tag (see Figure 42 ). These serial numbers MUST match. The tag is designed to be applied to the top right edge of the enclosure or to the lower right of the front of the unit. Drill pins (GSE part number 38-04-2960) are supplied with the panel mount kit to mount the tag. The drill pins require a 1/16” hole.
123
Chapter 6
To install the panel mount tag:
1.
Remove the electronics.
2.
Carefully score the case so the drill will not slip.
3.
Drill the mounting holes with a 1/16” drill.
4.
Gently tap the drill pins to secure the label to the case.
5.
Clean out the case.
6.
Re-install the electronics.
Damage to the case or electronics is not covered by warranty.
The NTEP panel mount requirements are applicable only to the Model 350 die cast model and panel mount kit.
Figure 42: Panel Mount Unit - Serial Number Tag (Die Cast Model)
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 to comply with OIML requirements, parameter P410-Euro must be enabled. Doing so 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 " .
Most NTEP requirements will also apply. See the Other Requirements section below for additional considerations.
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 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 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.
P HYSICAL S EAL
The most common sealing method is a lead-wire seal. The Model 350 and Model 355 provide an easy means of applying this type of seal as shown in Figure 45 .
Before applying a wire seal, move the program jumper to the ‘NO’ position as shown in Figure 43 and Figure
44 .
This will prevent access to the Setup and Calibration Modes.

A UDIT T RAILS
Three separate incrementing, non-resetable audit trail parameters are used by the Model 350/355 to indicate changes to various parameters, P60201 – OIML, P60203 – Calibration , and 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.

A/D Calibration Procedure
The Model 350/355 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 SPX GSE or your local authorized GSE distributor for more information on this procedure.
