A six digit LED display is used to provide weight indications and operator messages describing scale operation. Scale status such as motion (MOT), polarity (NEG) and center of zero (ZERO) is displayed on annunciators located to the left of the display area. Scale units are displayed on four annunciators located to the right of the main display. Fig.
Power Up: Connect the Model 7400, 4300, 7000XL to a compatible power source. With the 8000XL or scale models with battery option, press and release ZERO button to turn on scale. Basic Weighing Operation: 1) Remove all items from the scale platter. 2) Press the ZERO button to zero the scale. The weight display should now read zero. 3) Place an item on scale platter and wait for the motion (MOT) annunciator to go out, indicating a stable weight. 4) Read the weight on the scale display.
PRINT button:(7400 optional) The PRINT button permits the operator to send data to a printer or other external devices. The user must wait for motion to stop before pressing the PRINT button. Motion is indicated when the MOT annunciator is lit. The current weight will then be transmitted to the printer. When the data is transmitted, the left most display digit will momentarily display a "r" to confirm data transmission.
counter is 6 digits or 999999. When the maximum value is reached, the accumulator or counter will rollover. Note: The accumulator and counter feature can only be used in a non Legal For Trade application.
Battery Operation The 8000XL and other models with battery option are equipped with a self-contained Rechargeable Sealed Lead-Acid battery and charging circuit, both internal. The scale is designed to run continuously for 60 hours (with one 350 ohm loadcell) on a fully charged battery. To significantly extend this battery life, enable the Unit On Timer which will power down the scale automatically after a period of non-use.
Low Battery Indication: (8000XL or Battery option) The "BATT" annunciator indicates that the battery is in need of recharging. Once the "BATT" annunciator turns on, there will be approximately one more hour of battery life before the scale shuts down. When the battery is too low to run the scale, the scale simply turns off and will not operate again until the battery is recharged. The scale remains accurate and useable even with the "BATT" annunciator on.
Checkweigh Operation 7400 Zero Band Checkweighing Operation: 1) Remove all items from the scale platter. Place the target weight on the scale. 2) Press ZERO to zero the scale. The weight display should now be zero. Remove the target weight. 3) Place an item on scale platter and wait for the motion (MOT) annunciator to turn off, indicating a stable weight. 4) If the item is heavier than the over limit, the OVER indicator will light, If the item is lighter than the under limit, the UNDER indicator will light.
4300 Digital Entry of Over and Under Limits: (optional configuration) 1) Zero the scale. 2) If available, place an item with the desired weight on the scale. 3) Press and release the OVER button. The OVER and ACCEPT indicators will light followed by momentary "over" message. 4) The scale is in the scroll mode. Press either the OVER or UNDER button to increase or decrease the limit value. Holding a button longer will cause the count to accelerate.
NOTE: The Five band checkweighing operating mode ("5BA", "5BS", "5Bt", "5Bb") is available in four different optional configurations in the Check Weighing Operation Mode Menu. See Check Weighing Operation parameter "C.o." for more details. 4300 Digital Entry and Recall of High and Low Limits: 1) Press and hold the OVER button until the display shows "High" and the OVER and ACCEPT indicators flash. 2) Current weight value of saved limit will be displayed.
4300 Push-button Entry of High and Low Limits: (optional configuration) 1) Zero the scale. 2) Place an item with the desired high weight on the scale. 3) Press and hold the OVER button until the scale displays "High", the current weight then “donE.” The limit has been saved. 4) Remove the high item and place an item with the desired low weight on the scale. 5) Press and hold the UNDER button until the scale displays "Louu", the current weight, then “donE”. The limit has been saved.
Setpoint Operation All scale models can be configure to Setpoint Operation. The Setpoint Operation is available when the following parameters are configured. The Check Weighing Operation parameter "C.o." set to any of the menu options "5EA" or "5ES". The eight available outputs on the optional Digital Output Board are nominally configured to each of the Setpoint limits. There are two different methods of Setpoint entry of limits.
NOTE: To select a different Setpoint limit number. Use the UNITS or UNDER buttons to scroll through the eight available Setpoint Adjustment numbers to enter or recall their limit value. NOTE: To digitally enter in Setpoint limits, the following parameters must be configured. The Checklimit Entry Mode "C.E." menu is set to "SCS" option. See Checklimit Entry Mode "C.E." menus for more details.
Installation Guide + Signal (Red) - Signal (White) + Excitation (Green) - Excitation (Black) + Sense (Blue) - Sense (Brown) CAL S1 Calibration Mode push button Remove JU7 and JU8 when connecting a 6-wire load cell. (JU7 and JU8 must be present when connecting to a 4-wire load cell) Fig. 6: Load Cell connections Connecting a load cell or configuring jumpers requires the removal of the rear panel.
Load Cell and Power Connections: Load cell connections are made through a terminal block "TB1" located at the bottom center of the main board (see Fig. 6). The power cord connects to a connector "J1" adjacent to the transformer (see Fig. 7). These connections are accessible by removing the rear cover screws and laying the rear panel and front of scale on the work surface. To install a single load cell, remove the rear panel and check the JU7 and JU8 jumper configuration.
Calibration Guide Entering Calibration and Parameter Setup Mode: The Calibration and Parameter Setup Mode can be entered by three different ways. 1) The Front Panel CAL Access Feature on power-up (Available only on the 4300, 7000XL, 8000XL models or on models that have an optional UNITS push button installed.) To enter the calibration mode, power up the scale while pressing the ZERO and the UNITS button at the same time. When the “rEL Pb” is shown, release both buttons.
Once the desired capacity has been selected, place the correct capacity label on the front panel, to the right of the display. NOTE: On scales with factory installed platforms, the capacity is set at the factory. It will not be necessary to set the scale capacity. Resolution: After Capacity has been entered, the scale's Resolution (Count-By) will automatically be set for a nominal 5000 division level. To enter in a different Count-by setting, the scale must be in the Calibration mode.
If you want to select a weight between 2% and 100% of capacity, select the capacity range above closest to the desired weight. Then scroll to the exact weight by pressing CAPACITY to go increase the weight or PRINT to reduce the weight. This is not available on the Model 7400. 3. To complete the calibration process, place the correct weight on the platter and press ZERO and wait for the display to count down to 0. If the span calibration was in range, the display will return with "donE".
A/D Ranging: (Refer to this section only if you encounter a calibration problem) NOTE: On scales with factory installed platforms, the zero and span will lie within permissible limits. Load cell signal input range 0.283 mV/V to 5 mV/V. 1) Enter Calibration mode by using Front Panel CAL Access feature or by pressing the CAL switch (S1). 2) Press and release UNITS or PRINT until in the raw counts mode. 3) Return the scale platform to "No Load" by removing all items from the platform.
Parameter Setup The Excel Series has 54 calibration and parameters setup menu items, which can be accessed three different methods, CAL switch and the Front Panel CAL Access Feature on both power-up or after power-up. The Front Panel CAL Access Feature allows the user to change the scale’s calibration and parameter settings by way of entering in a password code. This Feature is only available when scale is not configured for legal for trade Switch mode (see Operating mode Setup Menu).
(Where 25 can be any valid capacity in lb or kg). Press the UNITS button to access the next menu item. To exit the Calibration and Parameter Setup Menu, momentarily press the CAL switch or scroll through the menu options, by pressing the UNITS button, until "donE n" appears. Press ZERO button until "donE y" appears and then press the UNITS button. The indicator will return to the normal weighing mode.
Parameter Review of Calibration and Setup Values: The Parameters values for the indicator may be quickly reviewed without entering in the Calibration and Parameter Setup Mode. Remove power and press and hold the ZERO button while you apply power. Hold the button until the scale begins to scroll through each of the parameters. The button may be released anytime after the review has begun. After parameters are displayed, scale will then go to the normal weighing mode automatically.

Data Communications Introduction to data communications: The scale data is sent to a printer or computer by using "asynchronous serial data communications." Data is broken up and sent one piece at a time to the printer or computer. In spite of this apparent simplicity, a basic understanding of serial data communications is needed when setting up the scale. The scale transmits letters and numbers to a printer or computer by replacing the letter (or number) with an eight bit ASCII code.
In many cases, the receiving unit is a slow printer with limited memory. In these cases, more data may be sent than the printer can use. Again, data may become lost or scrambled. To prevent this from happening, "Handshaking" is used. When the receiving unit is busy or incapable of receiving further data, it activates the handshaking; telling the sending unit to stop transmission. Then, whenever the receiving unit is ready for more data, it deactivates the handshaking and data transmission continues.
Auto Print 3 (AP3): Auto Print 3 transmits the first scale reading following the scale leaving motion, being above the adjustable threshold level and in the accept band. To adjust the Threshold level as a % of capacity, see the Threshold Level parameter. In Auto Print 3, no further readings will be sent until the scale returns to weight reading that is below the adjustable threshold level. The reading must be stable, in the accept band, and must be a valid reading before it can be sent.
"UPS" Format: The data string produced by the UPS format allows the scale to communicate with an UPS world ship program. Refer to Application Note at end of manual and Table 2 for details. "d3" Format: The data string produced by the d3 format allows the scale to communicate with a Live Scale (Virtual) Display portion of the Dimension software that is running on a computer. Note: that parameter d.o. should be set for continuous print "C.P." for the program to function properly.

Fuse Replacement: The Scale's line fuse (F1) is located next to the power terminal (J1). Make sure power is off, before replacing the fuse. Remove the fuse cap by unscrewing it counter clockwise, then pull the fuse out of the socket and insert the new fuse in socket (see FIG. 13). Then screw the fuse cap back on the socket and apply power to the scale.
4-20mA Analog Output (optional) Introduction The 4-20mA Analog Output Option is used to provide an analog output that is proportional to the weight on the scale platform. Because of the inherent noise immunity present in a current loop, an isolated 4-20mA analog output is ideal for use in noisy environments. The 4-20mA analog output option can be used to send weight data to a process indicator, a simple on/off controller or to a programmable logic controller.
Fig. 14.2: Example of a Active 4-20mA circuit. Fig. 14.3: Example of a Passive 4-20mA circuit.
Digital Output Board (optional) The Digital Output Board can be factory configured into four different versions. All four versions do include a relay driver circuit that can control up to eight outputs. The standard base version EXOPT104 consists of only the relay driver circuit. The EXOPT101 has an additional Wired Ethernet Network Interface, refer to Wired Ethernet section for more details. The EXOPT102 has an additional Wireless Ethernet Network (802.
Fig. 15.2: Digital Output Board Installed 6 Volt settings (Default): When using the 6 volt mechanical relay (RLY0033). Add Jumper at JU11 between pins 2 and 3. No jumper at JU11 between pins 1 and 2. JU25 should have no jumper. Unregulated 9-12 volt settings: Add Jumper at JU11 between pins 1 and 2. No jumper at JU11 between pins 2 and 3. JU25 should have no jumper. 5 Volt settings: When using the 5 volt mechanical relay (RLY0027). Add Jumper at JU25. Remove all other jumpers at JU11.
RS485 Communications (optional) The scale offers an RS485 data communications option. RS485 communications are similar to RS232 except that RS485 provides better noise immunity, it is suited to longer cable distances, and it will allow multiple scales to be attached to the same data line. RS485 achieves its performance advantage over RS232 by utilizing a differential input and output. In other words, the RS485 device sends two copies of its data; one in positive logic and in negative logic.

Scales (nodes) located between these ends do not need this resistor. JU3 and JU4 are used to provide bias to the bus and at least one pair of pull up / pull down resistors are required somewhere on the bus.
Internal Relay Option (optional) The Internal Relay Option (EXOPT106) allows up to four relays to be mounted inside the scale's enclosure. The relay control is described in Parameter Setup Section. This section discusses the installation and wiring of the relay controls. Three types of relays are available for use with the Internal Relay Option – Electromechanical and Solid State (AC or DC). Specify style of relay at time of order. Relays are socked so replacements can be installed in the field. Fig.
Internal Relay Setup: The internal relay option comes with an interface cable between the Digital Output board and the internal relay board for relay control. A second twelve conductor cable provides the relay output and exits the meter through a watertight. Leave this cable in place when configuring the outputs and refer to the output cable color code table. In the field, this cable will most likely be replaced.
Step-up Relay Circuit: If the current load to be switched is greater than the maximum current limit of the internal relay, i.e. 10 Amps for mechanical relay or 2 Amps for Solid State Relay. A stepup relay circuit is required in order to switch the higher current loads. See Fig. 19 for an example of a typical step-up relay circuit. Fig. 19: Example of a Step-up Relay circuit.
External Relay Box Option (optional) The External Relay Box Option (EXOPT107) consist of a +6V Power Supply and up to eight DIN rail mounted relay modules, see Fig 20. The Relay Box is a NEMA4X polystyrene enclosure (10" W x 7" H x 6" D) with a clear cover. The housing has knockout plugs with sizes of 7/8", 1-1/8", 1-1/2" located on all four sides, see Fig 20. Three types of relays are available for use with the External Relay Box Option – Electromechanical and Solid State (AC or DC).
Fig. 21: Knock-out Plugs External Relay Setup: The Relay module is offer with three different types of relays, mechanical and solid state (AC or DC). The mechanical relay’s output consists of terminal 4 - common (COM), terminal 3 - normally open (NO), and terminal 2 - normally closed (NC) (see FIG 22). The mechanical relay (OMRON G2R-1-SN) is rate for a maximum of 10A @250VAC or 10A @30VDC. Relay drive current for mechanical relay is 70mA @ 6VDC.

Wired Ethernet Option (optional) The Wired Ethernet Option (EXOPT101) connects your Excel Series scale to an Ethernet network. The Digital Output board equipped, with the Ethernet module, installs inside the washdown safe enclosure. The NEMA4X sealed RJ-45 Ethernet connector is bulkhead mounted to the rear panel of the indicator (See Fig 24). The Wired Ethernet Option auto senses 10/100Base–T networks, so network configuration is simple.
Doran Wired Ethernet Configuration Guide The Doran Wired Ethernet option comes with a NEMA 4X washdown safe bulkhead mount connector on the rear of the scale. The mating field installable connector is available from Doran (P/N EXOPT150) and can be installed on customer supplied cabling. You have two options for Wired Ethernet, Static IP or a Dynamic IP address. Dynamic IP works with a DHCP server and is the default configuration.
3. If you wish to have a Static IP address, click on Network under the Configuration header on the left. 4. To configure to a Static IP address, click on Use the following IP address radio button and fill in the required network IP address fields. The IP Address field contains the current IP address assigned by the DHCP server. This IP address can remain the same if desired. When configuring the static IP address, be sure that no other device on your network is actively using this IP address.
6. Return to the Digi Device Discovery program from step 1 and click on Refresh View. Check to see if the newly configured device does appear on the list of connected devices with the proper IP settings. Highlight the Ethernet device by clicking on it and the device settings will be shown in the Details window on the left of the program window. The device will show that it is configured and the IP address status will be shown to be DHCP or Static.
