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 DISPLAY

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.

Wiring

Wiring a load cell or communication port is simple on both the die cast and stainless steel models. Refer to the information in this section for more details.

STAINLESS STEEL MODEL 350/355

The stainless steel models must be wired through the strain reliefs located on the bottom or rear of the enclosure and connected to the main board. Refer to Figure 9 and Figure 10.

DIE CAST MODEL 350

A description of all wiring terminals is included on the bottom label of the zinc die cast enclosure as shown in Figure 11.

Figure 11: Model 350 Zinc Die Cast Enclosure Wiring Label

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. 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.

Figure 12: Model 350 Cable Tie on Die Cast & Load Cell Connection (J8)

Figure 13: Model 350/355 Stainless Steel Load Cell Connector (J10)

SERIAL PORT CONNECTIONS

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

Chapter 2

meters). However, much longer connections are possible if using a properly shielded, low-capacitance cable.

REMOTE KEY CONNECTION

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.



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.

Do not apply an external voltage to remote key terminals! Only a contact closure is required to activate the remote key input.

NETWORK CONNECTIONS

Apply the supplied label over the appropriate COMM PORT pin designations.

On the stainless steel enclosure, apply the label marked Model 350/355 SS to the main board above J8. Position the label so the REM (remote) on the main board is covered with the REM (remote) of the supplied label. The new label will redefine all of the other pin designations.

On the die cast enclosure, apply the label marked Model 350 STD to the outside of the enclosure. The supplied label RS485 COMM should completely cover the RS232 COMM portion of the factory installed label.

HALF DUPLEX (2-WIRE)

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.

FULL DUPLEX (4-WIRE)

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.

BOTH HALF DUPLEX AND FULL DUPLEX

The network boards on both end-points should install jumper 3 on the RS-485 option board to engage the 120 Ω termination resistor (R8). The boards between the two end-points should remove jumper 3 on the RS- 485 option board.

The isolated ground (ISO GND) should be connected in parallel from unit to unit. A shielded twisted two pair cable is recommended throughout the network.

Chapter 3

350/355 Technical Reference

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)

4. Snap the plastic spacers into the three mounting holes.

5. Gently press the option board into the socket.

6. Apply the proper portion of the included sticker to the COMM port. The label will either go over the silk screen on

the board or on the rear cover. (See table for location)

7. Reassemble the indicator.

BI-DIRECTIONAL

Both the transmit output and the receive input of the indicator are available as 20 mA signals. None of the handshake signals are supported for the 20-mA current loop operation.

BAUD

Only baud rates of 9600 baud and less are supported.

ACTIVE/PASSIVE

The Tx output may be used as an active or passive output from the indicator. Either active or passive is chosen depending upon which terminals are used for the connections. In active mode the indicator supplies the current. In passive mode, the external device supplies the current. The Rx input is available in passive mode only.

ISOLATION

The input and output are electrically isolated from the main board as well as earth ground and each other, for both passive and active modes of operation. Isolation is a minimum of 1000v.

Chapter 3

MAX VOLTAGE

Active mode Tx current loop provides a driving voltage of 12v. This will allow 20 mA current flow with up to a 600 ohm load. Passive mode will work with an external driving voltage of up to 50v.

CONNECTIONS

The field connections to the 20 mA circuitry will be made at the main board’s comm connector, i.e. the lever connector on the Model 350/355 Stainless Steel version and at the ‘D’ connector on the Model 350 Zinc Die Cast unit.

LABEL

On the stainless steel enclosure, apply the label marked Model 350/355 SS to the main board above J8. Position the label so the REM (remote) on the main board is covered with the REMOTE of the supplied label. The new label will redefine all of the other pin designations.

On the die cast enclosure, apply the label marked Model 350 STD to the outside of the enclosure. The supplied label should completely cover the RS232 COMM portion of the factory installed label.

CABLE

The length for the current loop is 1000 ft. maximum. This is for the entire loop, not from device to device. Example:

1 transmitter and 1 receiver can have a maximum of 500 ft. of 2 conductor cable between them.

CONNECTED DEVICES

While 20 mA current loops can allow for more than one transmitter and/or receiver, the indicator and/or option board do not include any address recognition or collision avoidance and/or detection to promote this

usage. If the 20-mA loop is intended to be used in this manner, proper planning for these issues is required

ON/OFF SWITCH

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.

NSTALLING THE ON/OFF SWITCH ON OLDER MODEL 350/355 STAINLESS STEEL

I INDICATORS

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:

• 36-20-2450 Rubber washer, 0.49 ID x 1.06 OD x 0.093 thick

• 36-20-2455 Stainless washer, 0.5 ID x 1.125 OD x 0.062 thick

BATTERY CHARGING

If needed, the battery will always be charging when the unit is plugged in, regardless of the switch position. Typically, it takes four hours to fast charge a fully discharged battery.

Battery voltage is monitored to provide a fast charge then a continuous trickle charge to maintain the battery while not in use.

OVERCHARGE PROTECTION

The battery state is monitored by the charging circuit to prevent overcharge and provide proper charge termination. Overcharging is also prevented through temperature sensing.

Battery voltage is monitored during charging to ensure a 100 percent capacity charge. The circuitry includes a safety timer to stop battery fast charging after 264 minutes.

Chapter 3

TEMPERATURE SENSING

If the ambient temperature sensor RT1 on the board is colder than 10 degrees C, the battery will trickle charge and not enter fast charge until the temperature rises above 10°C (50°F).

If the battery temperature sensor (connected between battery – and THERMISTOR) is warmer than 60°C (140°F), the charger will stop fast charging and revert to trickle charging. A fast charge cannot happen again until the battery has cooled and the unit is reset by turning off the ON/OFF switch and interrupting the AC power to the Model 350/355.

LOW BATTERY INDICATION

The Low Battery indication occurs when the battery is discharged below 11.4 VDC. Parameter 426 enables or disables the low battery indication. Low battery will be indicated continuously if this feature is enabled without the battery option installed.

DISPLAY INDICATION

A Model 350/355 with LED display will flash “LoBat” on the display as a warning when the battery is low. A Model 350/355 with LCD display will turn on the square indicator between the MOTION and GROSS indicators on the bottom of the display. LOBAT is written above the indicator on the LCD lens.

REQUIRED HARDWARE

You must have the following hardware in order to use low battery indication:

• Model 350 Die cast:

DEAD BATTERY SHUTDOWN

The battery option disconnects battery power to the Model 350/355 before erratic operation can occur. The shutdown occurs at a battery voltage of 10 VDC. The switch must be clicked from ON to OFF to ON again to activate battery power after it has shut down. This feature is part of the circuitry on the battery option board. The Model 350/355 Main Board type and EPROM version do not affect its use.

AUTOMATIC SHUTDOWN

The Battery Option System Version 2 has an automatic power off feature that is enabled by parameter 427. This feature allows the Model 350/355 to shut itself off using a programmable time period of inactivity on the scale. The choices for the time period are in minutes: 0.5, 1, 2, 3, 4, 5, 10, 15, 20, 25, 30, 35, 40, 45, and 60.

You must have the following hardware in order to use the auto power off feature:

P111 Division Size (Selection)

Indicates the count-by and decimal point. Pressing

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

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.

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 no-motion condition exists.

350/355 Technical Reference

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

A zero range of 5% is commonly used with large tank scales to avoid accidental zeroing of a full or partially full tank.

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.

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 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

.

WRITING 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.

ACCESSING 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.

ASCII Control Codes

Figure 37: Custom Transmit File

ENTERING ASCII TEXT

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.

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.

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).

ACTIVATION METHODS (GENERAL)

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.

The [REMOTE KEY] closure activates the setpoint. The remote key function (assigned at P800) is over-ridden.

Automatically activates the setpoint. It waits for a no-motion condition, then adds the target to the current displayed weight to achieve a relative cutoff value.

350/355 Technical Reference

PRE-ACTS (GENERAL)

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 Actual Cutoff

Value

Target = 400 lbs. Desired final weight. Pre-Act 1 = 28 400 – 28 = 372 Switch to slow feed at 372 lbs. Pre-Act 2 = .5 400 – 0.5 = 399.5 Final fill valve closes at 399.5 lbs.

Comments

LEARN FEATURE (GENERAL)

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.

PAUSE FEATURE (GENERAL)

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

BARGRAPH (GENERAL)

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 50. To weight each segment of the bargraph refer to parameter P5012 (bArPc) in the Parameter Map section beginning on page 50.

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.

Example#1: “ChecP” (refer to Figure 38) - Lower Limit is set at 50lbs.

- P5012 is set for 80%

- (Bar weight = 50 – 40 = 10 )

(10/8 = 1.25 lbs)

NOTE: Right-side bars will have the same scaling (lb per bar) as the left-side bars. They are represented as a mirror image of each other.

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.

Both

The ‘Both’ program combines a fill operation with a discharge operation. This automates a single-speed vessel filling operation with a single-speed multiple dispensing function. Setpoint 1 is used for filling the vessel and Setpoint 2 is used for product discharge. The ‘both’ program uses values for two targets and two pre-acts. Both targets must be based alike (net or quantity, quantity if count is selected).

Absolute Check-Weighing

This program is commonly used for check-weigh applications where the accepted tolerance will be an absolute value between and upper and lower limit.

After a target weight is entered, upper and lower tolerances are entered as absolute values. The desired target may be based on gross weight, net weight, or quantity (if counting is enabled). Only the annunciators will light to indicator the setpoint status. Be sure to enter both the upper and limits. Failure to enter one of these values will cause a setpoint error (refer to Chapter 7 on page 129 for more details on error codes).

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.
