Axle Sizes

Using Table 1: Configuration Code Example

Physical axle size and calibration axle size are not the same for some Weigh Bars. If your Weigh Bar physically measures 5/8" in diameter but is marked with a calibration axle size of 2-1/4" D (Dual), then use data shown in Table 1 for a 5/8" bar. If your Weigh Bar measures 1" in diameter but is marked with a calibration axle size of 2-1/8 ", use data shown in Table 1 for a 1" bar.

For Weigh Bars or weight transducers which have a physical axle size of either 5/8" or 1" but which have a calibration axle size other than 2-1/4" D or 2-1/8", respectively, select Custom Sensitivity and Capacity x Increment in Table 1.

For all other Weigh Bars or weight transducers, if physical axle size and calibration axle size of a bar do not match, use the calibration axle size for Table 1.

Table 1 shows you how selections shown for these parameters would be represented by a Configuration Code of 5151:

Configuring Custom Sensitivity with Capacity x Increment Size

 

You may exit this procedure from any display, except E, with GROSS, HOLD, or LOAD/ UNLOAD key.

This procedure allows you to select a weight transducer sensitivity rating other than those referenced by axle sizes in Table 1. You may even config- ure another manufacturer's weight transducer for interface with the Model 715. Before starting the keying procedure for custom configuration, you must verify three facts about your interfaced transducer(s):

Trade name of transducer

Sensitivity of transducer

Capacity x Increment Size of transducer

 

TRADE NAME OF TRANSDUCER

To configure custom sensitivity for Weigh-Tronix Weigh Bars, continue now to the next topic, SENSITIVITY.

To configure for transducers from manufacturers other than Weigh-Tronix, refer now to instructions located in the PROGRAMMING APPENDIX. Then, if you find that custom configuration of sensitivity is required, return to this section and proceed to the next topic.

SENSITIVITY OF TRANSDUCER

Determine the sensitivity rating, that is, mV/V output at full capacity, for the weight transducer(s) you are using. The transducer probably carries this information, or access to it, stamped or printed on the transducer itself.

Call the factory at 1-800-458-7062 for help in determining the Model 715 sensitivity rating for your transducer(s).

Because many different types of bars are used by various manufactur- ers, it is impossible to generically document a way to determine Model 715 sensitivity ratings for all available weight transducers.

Write down your calculated sensitivity rating: , using

this format:

n.nnnnnnn = your sensitivity rating 1 2345678 = digit places

You may key in a mV/V value of up to eight digits. Selection range for sensitivity is from 0.075 to 6.0 mV/V. Keep your notation handy for entry in steps 6 and 8 of the following keying procedure.

 

CAPACITY X INCREMENT SIZE OF TRANSDUCER

 

Refer to TABLE 4 and locate a Capacity x Increment Size combination that is appropriate for your Indicator.

Note the column number in which appropriate Capacity x Increment Size combination is located. Write down the column number: Keep

your notation handy for entry in step 3 of the following keying procedure.

Circuit Descriptions

Main Printed Circuit Card

 

This printed circuit card contains the

Power Supply

Analog-To-Digital Circuitry

Microprocessor Circuitry

Display Circuitry.

To prevent the unit from turning off below 10 volts, remove CR5 and C36. When configured this way, the unit will return to the Gross mode if it loses power.

This indicator, which is energized by 10 to 18 vdc in reference to a NEGA- TIVE GROUND utilizes two five amp fuses mounted on the bottom of the chassis for current protection. (Systems with a positive ground are modified by cutting jumpers from E11 to E12 and E9 to E10. Then install jumpers from E9 to E12 and E10 to E11.)

The circuit card receives power from the fuse at P2 and is protected against high voltage transients with varistor RV1.

Input voltage is monitored by 16 volt zener diode VR2. If the voltage across VR2 exceeds 16 vdc, Q3 will turn “ON” holding the power circuitry in the “OFF” condition. In addition, if the input voltage drops below 10 volts DC, PA7 disables the power circuitry by outputting a low signal.

A “Power On” command is generated when the ON key is pressed. This turns Q5 on and provides a low signal to +8v regulator (u18) pin1 enable input. When the power is turned off, the Q5 turns off, the Q4 turns on and a high signal disables (U18) the +8 regulator and turns it off.

The -7.5 vdc supply voltage is established by U7, a voltage convertor. This device inverts the input voltage to a -7.5 vdc level.

The +5 vdc voltage is provided by U8, a 7805 regulator.

As soon as the +8 volt power supply voltage is present, Q2 turns on which turns on the DS2 and DS3 LEDS

 

Analog to Digital Circuitry

 

The analog-to-digital circuitry consists of two weight voltage amplifiers (U1 and U2), a reference amplifier (U3), an analog switch (U4), switch control logic gate (U14C), a dual slope integrator (U5), and a comparator (U6).

An 8 vdc excitation voltage is supplied to the weight sensors from P1 pins 1 and 6. The millivolt signal received back from the weight sensors enters the analog-to-digital circuitry at P1, pins 3 and 4.

This millivolt signal is amplified and filtered by U1 and U2 to establish the amplified weight voltage (0 to +9 vdc) at U2 pin 6. This weight voltage is then provided to U4 pin 5. A logic low during the weight voltage interval at U4 pin 1 enables the amplified weight voltage to be received by the dual slope integrator (U5). Starting at zero volts, the integrator capacitor (C20) charges at ramp angle directly proportional to the amplified weight voltage but of opposite polarity. As the amplified weight voltage increases, the integrator output ramps more in the negative direction.

The voltage received from the sense lines enters the analog-to-digital circuitry at P1 pins 2 and 5. This sense voltage establishes a reference voltage of -9 vdc at U3 pin 6. The reference voltage is applied to U4 pin 10.

After the integrator capacitor has been charged for a fixed period of time, the Weight Voltage Interval, U4 pin 1 goes high. U14 applies a logic low to pin 14 of U4 which allows the reference voltage to be applied to the integra- tor. Since the reference voltage (-9 vdc) is of opposite polarity to the ampli- fied weight voltage, it causes the integrator output to ramp back toward zero. (This period of time is known as the Reference Voltage Interval.)

While the integrator output is ramping back to zero, the comparator (U6) signals the microprocessor to record this period of time in clock pulses. The microprocessor uses this number of pulses to calculate the amount of weight on the scale.

When the integrator reaches zero, the comparator output goes low which triggers U14C to remove the logic low at U4 pin 14 completing one analog- to-digital cycle.

This analog-to-digital conversion repeats at a frequency of 30 hertz.

 

Microprocessor Circuitry

 

The Microprocessor Circuitry consists of a Motorola MC68HC11A1 8-bit microprocessor IC (u11), a 74HC573 tristate latch (U12), a 27C128 EPROM (U13), and various other components.

The microprocessor features on chip memory 256 bytes of RAM, 512 bytes of EEPROM, along with a Computer Operating Properly (COP) watch dog system.

A 2 MHZ internal clock is contained in the microprocessor and is controlled by an external crystal (Y1). Output (ECLK) from this clock provides timing reference for the EPROM (U13), and input to voltage monitoring circuit U9.

The microprocessor communicates with Analog-to-Digital switch control logic gate U14 through ports PA2 and PA6. Through U14, the timing refer- ence for the Reference Voltage Interval and Weight Voltage Interval are provided.

The switches on the front panel receive a signal from ports PD2-PD5 on the microprocessor and they are monitored for an electrical change by ports PE0PE3 on the microprocessor.

As signals are received by the microprocessor, it will send them to the EPROM (U13) on the address lines A0-A15. The signals will be translated and held by U12. Once all translating is completed, the microprocessor will enable U12 to return the new information on data lines D0-D7 to the micro- processor. Then, the appropriate device will receive a signal from the microprocessor.

The Computer Operating Properly (COP) watch dog system in the micropro- cessor detects errors introduced by electromagnetic interference. If an error is detected, the microprocessor is reset and operation continues. When the indicator is powered up, the momentary displayed "hi" message, indicates the watch dog system is active.

If a "hi" message is displayed, the indicator will perform correctly, but will not be guarded by the COP watch dog system. This may happen when a new microprocessor IC is installed. The COP watch dog system can be activated by following this procedure:

Turn the indicator OFF jumper P7-1 to P7-2 and P6-1 to P6-2

Turn the Model 715 ON for a few seconds

Turn the Model 715 OFF

Remove the jumpers

 

Display Circuitry

 

Optional RS-232 or Remote Circuitry

To Install Remote Receiver

The six digit liquid crystal display (DS1) features black segments against a silver transflective background.

Liquid crystal display driver U15 requires a +5 vdc power supply and two signal inputs from the microprocessor to function: (1) a 33-bit serial data input and (2) a microprocessor controlled input. When both of these condi- tions have been met, the display driver will energize the appropriate seg- ments on the display.

Additional circuitry required to provide either an RS-232 communications interface or a remote display interface requires R49-57, C48-51, U16, U10, and P6 connector.

The RS-232 transmitter/receiver (U10) internally generates +10v and -10 v supplies and meets all EIA RS-232C specifications. Through U10, the microprocessor communicates with peripherals which will accept the follow- ing protocol: baud rate 1200, 1start bit, 8 data bits, no parity, and one stop bit. The RS-232 communications port supports X-on (HEX 11), X-off (HEX 13_) handshake and responds to an inquire character (HEX 05) print request.

The invertor/buffer gates (U16) are used in the remote clock, remote data, remote zero, and remote print lines to provide isolation and assure proper logic; levels to and from the remote display.

P6 connector provides external access to power supply voltages, RS-232 data lines, remote displaydrive lines, remote zero lines, and remote print lines.

After installing PC board assembly P/N 27643-0030 as shown in assembly section, plug 3 pin cable assembly into P8. This enables user to have remote zero capabilities within the Model 715. Be sure to match dip switch selections between receiver card and transmitter. Place antenna through small hole in the lower stainless steel assembly in order to function properly.

 

Programming Appendix

 

A new feature makes the Model 715 more easily configurable with J-Star and Eaton transducers than before. The added J-Star/Eaton interface protocol slightly modifies display and keying sequences for accessing Configuration Mode, Calibration Mode, and Internal Raw Counts Mode. The Model 715 has added two more (716E, 717E) menus to make converting between different Weigh-Tronix applications even more flexible than it was with the 700E model.

 

Configuration for J-Star, Eaton and Two Additional

 

Weigh-Tronix Menus

New displays and keying sequences require modified instructions. Modified documentation presented in the PROGRAMMING APPENDIX applies whenever you change the transducer interface on your system, and the change means a different transducer trade name than that previously configured for. This includes switching from J-Star or Eaton transducers back to Weigh-Tronix Weigh Bars.

In applications where Weigh-Tronix Weigh Bars are retained, original documentation applies.

When switching the transducer interface on a system means a change in transducer trade names, follow the modified procedure shown below and illustrated in FIGURE 2 to access Configuration Mode, Calibration Mode, and Internal Raw Counts Mode.

Always execute the steps below before keying in a new Configuration Code or trying to calibrate a transducer with a different trade name.

Key in 715 and press E key for

two seconds. . . Currently configured menu is displayed: For Weigh-Tronix, 715E, 716E; for Eaton, EAtn 717E; for J- Star, JStr.

You now have two choices, A or B:

If displayed menu is correct, skip to step 4. OR

If displayed menu does not correspond with new transducer interface, press and hold E key until next menu appears.

If each of the Weigh-Tronix menus have been configured for different applications, it is possible to bounce between the 715E, 716E, and 717E menus. Press 715, 716, or 717 and hold the E key until the optional menu is displayed.

Continue keying as appropriate to access desired modes.

 

Configuration Code Charts

 

Using the Eaton Configuration Code Chart (Table 6)

Using the J-Star Configuration Code Chart (Table 7)

To determine an appropriate Configuration Code for J-Star or Eaton trans- ducers, consult the Configuration Code Charts in Tables 6 or 7.

The Eaton Configuration Code Chart (See Table 6) shows you how selec- tions listed below for five configurable parameters would be represented by a configuration code of 4151. Notice that each digit in the code represents a parameter, and the value of each digit represents a selection for that parameter as shown in Table 8: Eaton Configuration Code Chart.

& Auto Hold Mode 5th digitlb/ON 1
CODE 4151 uses 2nd, 3rd, 4th and 5th of five available digits.

 

The J-Star configuration Code Chart (See Table 7) shows you how selec- tions listed below for five configurable parameters would be represented by a Configuration Code of 3151. Notice that each digit in the code represents a parameter, and the value of each digit represents a selection for that parameter as shown in Table 9: J-Star Configuration Code Chart.

RD712XL REMOTE DISPLAY DISPLAY PC BOARD P/N 48865-0029, COMPONENTS AND SCHEMATIC

 

XM710-L WIRELESS REMOTE INSTALLATION

The XM710-L hand-held transmitter provides the ability to remotely perform a zero/reset command and can be installed

in MODEL 715 or RD712 / 712XL. The XM710-L wireless remote system is similar to those used on garage door openers. For selectable security, the transmitter and receiver assembly boards have programmable security code switches.

The eight position switch is used to determine the security code. These can be programmed to a different code, but the programmed code must match on both the transmitter and receiver. The unit is shipped from the factory with the following settings:

1, 3, 5, 7 = ON (closed)

2, 4, 6, 8 = OFF (open)
