

3000 Model 3100 or 3200

Static Weight Indicator. The Model 3100 is designed for noncommercial use and the Model 3200 for higher accuracy and in cases where weights and measures approval is required. The manual refers to Model 3100 only as both operate the same.

1.1 Unpacking and Inspection

The Micro-Tech 3100 has been properly packaged for shipment and storage, when necessary. Refer to the appropriate manual in the appendix section for unpacking procedures for optional equipment.

Inspect all packages for damage before opening; sometimes the carrier may be responsible for shipping damage. Refer to the appropriate manual in the appendix for inspection procedures for optional equipment.

1.2 Storage

The Micro-Tech 3100 can be safely stored, with cover, latches secured and hole plugs installed, between -40

° to +158° F (-40° to +70° C). The units should be protected against moisture.

1.3 Application

The Micro-Tech Model 3100 /3200.Field Mount and Panel Mount is a busbased microcomputer driven instrument used for static weighing of bulk materials. Common application are C-Level, Unitrain Load-out and check weigh bins for in-line conveyor belt scale calibration.

The Static Weight System includes the following principal components :

1. Load Receiving Element

That element of a scale designed to receive the load to be weighed (for example: platform, deck, rail, hopper, platter, plate, or scoop). See the installation drawing for specific type of load receiving element supplied with your system.

2. Load Cell System

Thermo Ramsey uses three load cell systems depending on the application.

They are tension, compression, and shear beam.

3. Static Weight Indicator Model 3100

Field mount or panel mount static weight indicator is designed to convert force signals from 1 to 6 strain gauge load cells to an accurate stable signal for local and remote weight indication. The static weight indicator can accept up to four scale inputs depending on the selection of plug-in A/D boards.

REC XXXX 1-1


Remote indication may be by digital and analog outputs or by serial communications that can be configured according to the following standard.

All are optically isolated.

- RS423/RS232C For point-to-point asynchronous bidirectional communications, maximum 50 ft (15 m). Modem capability.

- RS485/RS422 For point-to-point multidrop 4 wire bidirectional communications, maximum 4000 ft (1200 m).

- Current Loop For high immunity bidirectional asynchronous communications. Passive only.

2.2.1 Critical Wiring Conditions

1. Ensure power is off at the mains

2. Do not route load cell and signal cables in the same conduit with power cables or any large source of electrical noise.

3. Earth ground all enclosures and conduits. A ground connection between all conduits is required.

4. Connect the shields ONLY where shown.

5. Check that all wires are tight in their connections.

6. Never use a “megger” to check the wiring.

7. A readily accessible disconnect device shall be incorporated in the field wiring. This disconnect should be in easy reach of the operator and it must be marked as the disconnecting device for the equipment.

8. All conduits should enter the bottom of the enclosure. Do not run conduit through the top or sides of the enclosure.

2.3 Field Mount Installation

The field mount Static Weight Indicator should be mounted in a controlled environment not be exposed to excessive vibration, heat, or moisture, and protected from direct sunlight. The Static Weight Indicator may be mounted up to 3,000 feet from the scale ( Figure 2-1

Mount the Static Weight Indicator to a rigid, flat, vertical surface using four mounting holes provided on the back of the enclosure. Care should be taken to ensure the mounting surface is flat so as not to twist or warp the fiberglass enclosure when tightening the mounting bolts.

Connecting Incoming Power - Field Mount

To connect the incoming power, use the following procedure.

Note: All units shipped from the factory are configured for 115 VAC. If you desired 230 VAC make sure the power selector switch is set to 230 VAC

(

Section 2.5.1

).

1. Loosen the screw latch mounted on the front chassis. Open the door (see

Figure 2-3

).

2. Route incoming power wiring through a conduit hole at the bottom right of the enclosure. Leave ample loose wiring (typically 8”) to facilitate removing the terminal connectors.

3. Wire safety ground terminal located on the side of the chassis.

4. Wire HOT to Terminal L on Power Input Terminal.

5. Wire NEUTRAL to Terminal N on Power Input Terminal.

6. If additional I/O is required at the line voltages, these wires should be routed through a conduit hole on the bottom right of the enclosure. Leave ample loose wiring (typically 8”) to facilitate removing the terminal connectors.

REC XXXX 2-5


7. All additional field wiring operation at voltages less then 30 V must be located on the left bottom of the enclosure. Leave ample loose wiring

(typically 8”) to facilitate removing the terminal connectors.

8. Close the inside panel and tighten the screw to secure the cover.

2.4 Panel Mount Installation

The panel mounted Static Weight Indicator is suitable for mounting in a control panel. The control panel should not be exposed to excessive vibration, heat, or moisture. The front bezel, when properly seated, forms a dust seal.

A two (2) inch clearance around the top and bottom of the Static Weight

Indicator is required for convection cooling. Additional clearances may be required if equipment mounted directly below generates excessive heat.

Clearance in the back is necessary for wiring access and fuse replacement.

Clearance on the side is necessary for inserting the chassis holding brackets from the back after insertion of the Static Weight Indicator.

Provide a cutout in the panel and insert the Static Weight Indicator after removing the holding brackets. From the back, insert the holding brackets on both sides of the instrument. Tighten the holding brackets to support the Static

Weight Indicator and form the dust seal.

A/D channel #2 is used for a platform scale with range of 200 Tons. When long trucks need to be weighed, both scales are used. Scale #3 is defined as S1+S2, so that the Scale #3 indicates the weight of Scale #1 plus the weight of Scale #2.

Scale #3 has a range of 300 Tons.

Micro-Tech 3100 Operation

Your Thermo Electron Static Weight Indicator System is capable of accurate weighing, provided it is installed, calibrated, operated, and maintained in complete accordance with the instructions contained in this manual.

3.1 Overview

Micro-Tech 3100/3200 Static Weight Indicator is a microcomputer-based instrument that accepts and conditions weight signals and provides visual and electrical outputs for total weight . A stable 10-volt DC excitation voltage capable of exciting up to six 350 ohm strain gauge load cells is produced by the

Static Weight Indicator. Sense lead terminations are also provided for six wire load cell cables.

Auto Zero (AZ) Track enables the scale system to automatically zero itself during extended periods when the scale is empty. Auto Zero Track is menu selectable. The letter “Z” appears on the first line of the display indicating Auto

Zero Track option is enable.

Life expectancy of the RAM support battery is approximately ten years, if power is not applied. Under normal operation where power is on continuously, life expectancy is much longer.

Errors may occur during initial calibration and their reason must be corrected during initial calibration. During normal operation, an error would most likely indicate a failure in system or improper operation.

The front panel (Figure 3-1) contains the necessary status indicators and keys to enable the operator to perform calibrations and all required operations after the

Static Weight Indicator has been configured in Section 2.5.

3.2.1 System Status Lights

The five red status indicators show the status of the Static Weight Indicator.

NET

ON indicates when a net weight is displayed, in other words, it is on when a tare weight has been acquired.

If more than one scale is defined, the ON indication refers to the displayed scale

STABLE WEIGHT

The stable weight condition is determined on the basis of two parameters : motion band and motion delay.

Motion band defines a range in which the weight is stable, and motion delay defines the time the weight should stay in the range before stable weight indications turns on.

If more than one scale is defined, the ON indication refers to the displayed scale.

ZERO WEIGHT

Net weight is considered zero when its value is between +/- 0.5 scale division.

The weight must stay in this range for 2 seconds after the weight becomes stable zero weight indication is turned on.

If more than one scale is defined, the ON indication refers to the displayed scale

ALARM

Alarm indication flashes if an alarm is pending, either the alarm is NEW or has been ACKNOLOWLEDGED.

READY

Ready indication turns on if the scale is calibrated (zero and span calibration complete) and no SHUT DOWN conditions are active.

If more than one scale is defined, the READY indication refers to the display scale.

The LCD graphic display indicates actual running information or displays menu entry information.

This part of the procedure is only executed if a calibration with test weights was done before, and if R-CAL has not been factored yet.

It is very important to understand that when this procedure is executed, the

system will not alter the span. The system assumes the span is set correctly based on a test weight calibration. The system acquires the R-CAL FACTOR.

The factored R-CAL can then be used to check the span between test weight calibrations.

This part of the procedure is only executed if a calibration with test weights was done before, and if R-CAL has not been factored yet.

It is very important to understand that when this procedure is executed, the

system will not alter the span. The system assumes the span is set correctly based on a test weight calibration. The system acquires the R-CAL Factor. The factored R-CAL can then be used to check the span between test weight calibrations.

If EXIT is pressed, the system acknowledges that the R-CAL factor is not used.

The effect of this is that the system does not ask for a factor any more for this calibration method unless a manual span entry is done. By pressing EXIT, the operator tells the system that he does not want to use factors, but wants to use the test results for changing the span number.

After EXIT is pressed, go to point (4.). If REPEAT is pressed, go to (A) above.

CLEAR soft key is pressed or the Run Menu is entered. If an output is forced and the scroll key is used for reaching some other menu, the output stays in the forced status until RUN is pressed. This allows the operator to check inputs while outputs are still in the forced status.


Dig output test output # 1 : ON/OFF

ENTER ON/OFF


To force an output, enter the desired number followed by ENTER. Then use the SET/RESET key to force it to the ON or OFF status. After the output has been forced, the CLEAR soft key appears in the middle position.

Slots are numbered 1-3; slot 0 is the motherboard.

The Micro-Tech 3100 has a fully programmable printer format. The following section explains how to program it according to the specific needs.

1. Define Handshaking

The system can be configured to operate without a handshake (NONE), or using the Clear to Send signal (CTS) or the XON-XOFF sequence. Refer to the printer instruction manual to define which selection is required. The selection NONE is only used for testing purposes. It is not recommended for normal use. If NONE is selected, the system is not able to recognize if the printer is on line or not, or if the paper is empty.

The most commonly used protocol is the CTS, which is a signal generated by the printer to indicate whether it is ready to receive data or not.

This menu is only displayed if the Audit Trails option is installed.

Audit trail meets NIST HB 44 Category 3: Remote configuration capability, access may be unlimited or controlled through a password. It consists of an event logger that includes an event counter (000 to 999), the parameter description, the date, and time of the change, and the old and new value of the parameter. Parameters may be configuration parameters or routine calibration.

Events and changes may be viewed on the Instrument’ s display or printed out by an on-site printer.

The Logger records the before and after setting all configuration parameters that affects the calibration of the scale. It also records when calibration was performed. The Event Counter increments one count for each event.

Audit trail records the time and displays the new and old data for any change in the parameters and functions listed below, indicating each by an event number:

B.2 Digital Input/Output Board Configuration

In addition to the programmable digital inputs and outputs on the motherboard, optional Digital I/O (DIO) expansion boards can be added. Available boards are

DIO input board 16 inputs/4 outputs, output board 16 outputs/14 inputs or 20 inputs/20 outputs by adding both boards.

Both DIO boards provide isolated contact closure inputs and 24-volt current sinking (default) or current coursing (consult Factory) isolated outputs. The

DIO input board connector J16 is male 25 pin sub-miniature D Connector and the DIO output board connector J15 is a female connector.

Selectable jumpers OP1 and OP2 located on the lower right hand side of the DIO boards control internal or external 24 VDC power for the DIO boards. All inputs and outputs use the same selected power supply.

Appendix Table B-1: DIO Board Jumper Settings (OP1/OP2)

DIO BOARD JUMPER SETTINGS

POWER SOURCE OP1 OP2

The isolated contact closure inputs are activated by completing the circuit from the input to the negative side of the 24 VDC supply. Approximately 5 mA of current flows out of each input during contact closure.

The outputs of the DIO boards use 2803 current sinking (default) type IC’s. The output IC’s are installed in sockets to allow replacing the output IC only rather than the board if the IC is damaged.

The output IC’s can be replaced with 2981 type IC’s for current sourcing applications. Wire jumpers W1 through W4 must be relocated for current sourcing. In most cases, it is recommended the boards be returned to the factory for converting from current sinking (default) to current sourcing.
