2.0 INTRODUCTION • The GBC/GFC series provides accurate, fast and versatile parts counting scales. • There are 2 types of scales within the GBC/GFC series: GBC/GFC scales are kilogram/gram scales and the GBC/GFC-a scales are changeable from pounds to kilograms if the user requires it. The scales have the same functions except that GBC/GFC-a scales have the ability to toggle between the weighing units. • All scales are supplied with a RS-232 bi-directional interface and real time clock (RTC).

3.0 INSTALLATION 3.1 UNPACKING The user’s application and the technical specifications of the platform or load cell will determine the necessary configuration. 3.2 LOCATING • • • • • • • • The scales should not be placed in a location that will reduce the accuracy. Avoid extremes of temperature. Do not place in direct sunlight or near air conditioning vents. Avoid unsuitable tables. The table or floor must be rigid and not vibrate. Avoid unstable power sources.
3.3 SETTING UP THE SCALES • The pillar is attached to the base using a bracket that must be attached to the base frame first using the 4 bolts supplied. The pillar is secured to the bracket using 2 sets of screws. The cable from the base to the indicator module is run through the tube and taken out through the plastic support at the top. Excess cable can be stored within the tube. • The GBC/GFC Series comes with a stainless steel platform packed separately. Place the platform in the base.
4.0 KEY DESCRIPTIONS Keys [0-9, .] Functions Numeric entry keys, used to manually enter a value for tare weights, unit weight, and sample size. [CE] Used to clear the unit weight or an erroneous entry. [M+] Add the current count to the accumulator. Up to 99 values or full capacity of the weight display can be added. Also prints the displayed values when Auto print is switched off. [MR] To recall the accumulated memory. [Pst] To set the upper limit for the number of items counted.
5.0 DISPLAYS The scales have three sections. These are “Weight”, “Unit Weight” and “Count”. The LCD design is: WEIGHT UNIT WEIGHT COUNT 5.1 WEIGHT DISPLAY It has 6-digit display to indicate the weight on the scale.
5.2 UNIT WEIGHT DISPLAY This display will show the unit weight of a sample. This value is either input by the user or computed by the scale. The unit of measurement is grams if grams if kilograms is selected for the weighing unit, or pounds if pounds is selected. 5.3 COUNT DISPLAY This display will show the number of items on the scale or the value of the accumulated count. See the next section on OPERATION. 5.
6.0 OPERATION NOTE: GBC/GFC-a Scales only SETTING THE WEIGHING UNIT, lb or kg The scale will turn on displaying the last weighing unit selected, either kilograms or pounds. To change the weighing unit press the [U. Wt./Units] key when the “Unit Weight” display shows zero. If necessary press the [CE] key to clear the unit weight before changing. 6.1 ZEROING THE DISPLAY • You can press the [Zero] key at any time to set the zero point from which all other weighing and counting is measured.
[Tare] key to set the preset zero value. • If the display was at zero the weight will show a negative value equal to the preset tare value entered and the “Net” indicator will be on. 6.3 PARTS COUNTING 6.3.1 Setting Unit Weight In order to do parts counting it is necessary to know the average weight of the items to be counted. This can be done by weighing a known number of the items and letting the scale determine the average unit weight or by manually inputting a known unit weight using the keypad. A.
B. Entering a known Unit Weight • If the unit weight is already known then it is possible to enter that value using the keypad. • Enter the value of the unit weight in grams, using the numeric keys followed by pressing the [U. Wt./Units] key. The "Unit Weight" display will show the value as it was entered. • The sample is then added to the scale and the weight will be displayed as well as the quantity, based on the unit weight. 6.3.
• • • • • values in the memory by pressing the [M+] key. The "Weight" display will show the total weight, the "Count" display will show the total accumulated count and the "Unit Weight" display shows the number of times, the items have been added to the memory for accumulation. The values will be displayed for 2 seconds before returning to normal.
7.0 USER PARAMETERS The parameters are set to customise the scale to suit the weighing applications. You need to enter a secure menu by entering a password when requested. • Press [Tare] once, during the initial counting of the display after the power is turned on. • The “Weight” display will show "PIn " requesting for the password number. • The default password is "0000" but other numbers can be set using the parameter menus. Press the [0] key four times. • Press the [Tare] key.
SETTING OF PIN • Display will show “F2” “Pin”. This parameter allows setting of a new password number. The default password is “0000”. • Press [Tare]. The “Weight” display will show "Pin 1". • Enter the new password number. The “Unit Weight” display will show dashes. Press [Tare]. • The “Weight” display will change to "Pin 2 ", Enter the password again and press [Tare]. • The display will show "donE" to show the new password has been accepted and will return to the menu.
8.0 CALIBRATION • The GBC/GFC scales are calibrated using metric weights and GBC/GFC-a scales are calibrated using metric or pound weights depending on the unit in use before calibration. See the Service parameters section for more information. • The scale will display a value of the weight to be used for calibration, this value is the last weight used for calibration. You can enter a different value, if desired. • For entering Calibration, see section 7.
9.0 RS-232 INTERFACE The GBC/GFC Series are supplied with a RS-232 bi-directional interface. The scale when connected to a printer or computer through the RS-232 interface, outputs the weight, unit weight and count.

9.1 INPUT COMMANDS FORMAT The scale can be controlled with the following commands. The commands must be sent in upper case letters, i.e. “T” not “t”. Press the Enter key of the PC after each command. T Tares the scale to display the net weight. This is the same as pressing [Tare] key. Z Sets the zero point for all subsequent weighing. The display shows zero. Same as pressing the [Zero] key. P Prints the weight, unit weight and totals same as pressing the [Print] key.
9.2 RS-232 SETUP The RS-232 interface uses parameters set by the user for language, baud rate and date format. Press and hold the [Print] key for 4 seconds to access the parameters. Press [U. Wt./Units] to scroll through the options and [Tare] to confirm the change and then advance to the next parameter.
