3 INSTALLATION 3.1 UNPACKING This indicator must be connected to a load cell platform and calibrated as necessary to match the platform and user requirements. See Section 15 for set-up information. The users application and the technical specifications of the platform or load cell will determine the necessary configuration. 3.2 LOCATING 11 | P a g e • The scales should not be placed in a location that will reduce the accuracy. • Avoid extremes of temperature.
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 GFK Series comes with a stainless steel platform packed separately. Place the platform in the base.
4 KEYPAD KEYS PRIMARY FUNCTION [Zero] Sets the zero point for all subsequent Escape from any setting menus weighing. The display shows zero. [Tare] It tares the scale and stores the current Accept the set values weight in memory as a tare value, subtracts the tare value from the weight and shows the results. This is the net weight. [Unit] This is used to select the weighing units Allows the weight, unit weight, and from a preset list of available units.
[Low Limit] & It sets the limits for check weighing and None allows setting of either the low limit or the high limit or both. [High Limit] [ Lim] It stores and recalls any of 10 preset limits [Func] This is used to select percent weighing, RS- None 232 parameters, Operation of the bar graph, RTC settings, User ID and Scale ID. [Count] Enter Parts Counting [Print] It is used to print the results to a PC or None printer using the RS-232 interface.
5 DISPLAY 5.
Next to the LCD are a number of LED’s that show when the weight is below, within or over the limits during check weighing. Weight LED LCD below the low limit Amber LO Within the limits Green OK Red HI Above the high limit NOTE: The LED’s can be set by the user to off, bar, spot or segment mode. See “F3 LED” in section 13.
The Counters are incremented any time the calibration section or the Factory parameters section have been modified. At power on, the display will show the current software revision number followed by the message of the Calibration Count “[AL[nt” then a number i.e. “123”. The number from the counter memory. Then the Parameter Counter message of “PAr[nt” and probably a different number, i.e. “234”. The counters cannot be reset to 0, they will increment until the display can no longer hold the values.
7 BATTERY • The scales can be operated from the rechargeable battery, if desired. The battery life is determined by the number and impendence of the load cells connected. With a single load cell and backlight disabled the life is approximately 70 hours before needing to be recharged.. • When the battery needs charging a symbol on the display will turn on. The battery should be charged when the symbol is on.
10 OPERATION 10.1 ZEROING • You can press the [Zero] key at any time to set the zero point from which all other weighing and counting is measured. This will usually be necessary when the platform is empty. When the zero point is obtained the display will show the zero indicator. • The scale has an automatic re-zeroing function to account for minor drifting or accumulation of material on the platform.
will be displayed. NOTE: When the container is removed a negative value will be shown. If the scale was tared just before removing the container, this value is the gross weight of the container plus all products which were removed. The zero indicator will also be on as the platform is back to the same condition it was when [Zero] was pressed last. Press [Tare] or [Zero] to remove the tare value and display zero. The Net indicator will disappear. 10.2.
WEIGHT To determine the weight of a sample, first tare an empty container if used, then place the sample in the container. The display will show the weight and the unit of weight currently in use. To change the weighing unit press the [Unit] key. The only alternative weighing unit is pounds. This can be enabled by the user in the parameters section. See section 13.3. 10.3 PARTS COUNTING The scale can be used to count parts based on the average weight of a sample weighed.
• Either place 10 parts on the platform for determining the average piece weight or use a different number of parts. For example, place 20 parts on the platform, press [CE] to clear the last values and then enter the value 20 using the numeric keypad. • Press [Cnt] to weigh the samples and determine an average piece weight. • If the parts are too light to measure accurately, the count may become faulty. It is suggested that the samples to be weighed should each weigh more than the resolution of the scale.
• • To count a different sample quantity, press the [Count] key. The display will show the last used sample size. Either use this sample size with a different part or enter a new sample size as above. • To return to weighing, press [Unit] when “XX pcs” is displayed.
10.4 CHECK-WEIGHING Check-weighing is a procedure to display an indicator or sound an alarm when the weight on the platform meets or exceeds the values stored in the memory. The memory holds values for a high limit and a low limit. Either or both the limits can be set by the user. NOTE: 1. The alarm and the LED bargraph can each be set to OFF (See section 13.1). The LCD display will indicate whenever the weight is within or exceeds the limits by showing ‘OK’, ‘HI’ or ‘LO’.
10.4.1 Setting up while weighing • Press the [Low Limit] key. It will show the current low limit. The “LO” symbol will appear on the display. • Press the [CE] key to clear the old value and then enter the new low limit using the numeric keys. The decimal point is fixed at the position that is used for the current weighing unit. When the desired value is shown press [Tare] to accept the value. If you want to reset the value to zero, press [CE] to clear the value.
10.4.2 Setting up while parts counting or % weighing During parts counting and percent weighing the limits are set in the same way as above. The limits are displayed in pcs or %. See Section 10.4 for the description of parts counting and Section 10.7 for percent weighing. NOTE: 1. The weight must be greater than 20 scale divisions for the checkweighing to operate. 2. To disable the check weighing function, enter zero into both the limits as described above.
Press the [ Lim] key. If you are already in the check weighing mode the display will ask if you wish to store the current limits by showing “StOrE” or recall another set of limits by showing “rECALL”. The [ Lim] key can be used to toggle between “StOrE” and “rECALL”. If you want to store the limits, when “StOrE” is displayed press the [Tare] key. The display shows “St ”. Enter a number corresponding to the desired memory location (0 to 9).
NOTE: 1. If the recalled limit is for parts counting, the display will show the last sample value used, ready for a new sample to be counted. 2. If the recalled unit is a percent weighing limit, the display will show the last sample value used, ready for a new sample to be weighed. 3. If the memory location was empty the scale will return to weighing. 10.6 PERCENT WEIGHING The scale can be set to perform percent weighing. See Section 13.1.
• Press [Tare] again to enter percent weighing. The scale will set the sample mass on the platform as 100% reference weight. NOTE: If there is no reference weight on the platform and percent weighing function is entered, pressing [Tare] again will return the indicator to normal weighing. • Remove the sample weight. Then any other weight placed on the scale will be displayed as a percentage of the original sample.
• If the scale shows “x x . x x %”, which is the last weight used as a reference, press [CE] to clear and use the numeric keypad to enter a new value. Press [Tare] to accept the new reference weight. • The weight entered must be greater than 50 scale divisions. ] • Press [Unit] to return to normal weighing. NOTE: The display may jump by large numbers unexpectedly if small weights are used to set as 100% reference. The scale checks if the weight is too small and will show Error 7.
10.7 ANIMAL (DYNAMIC) WEIGHING The scale can be set to animal (dynamic) weighing for weighing any items that are unstable or may move. . See Section 13.4. The scale will use a special filter to minimise the effects of any movement on the platform. • Press [Func]. The first option is “FUnC 1”, press the [Func] key 3 more times to display “Func 4”. • Press the [Tare] key. “F4 PCt” will be displayed. Press the [Func] key to advance to the second function, “F4 AnL”, Animal weighing.
10.7.1 Animal Weighing Procedure • With the platform empty the display will show zero weight.. Place containers or blankets onto the platform and press the [Tare] key to zero the display. The scale may go into the animal weighing procedure when the items are placed on the scale but will return to showing zero when the [Tare] key is pressed. • Place the animal to be weighed on the platform. The display will show “Ani” until a stable weight is determined.
10.8 ACCUMULATED TOTAL The scale can be set to accumulate when a weight is added to the scale automatically or manually by pressing [Print]. See Section 13.2. NOTE: 1. The accumulation function is available only during weighing. It is disabled during parts counting or percent weighing. 2. The accumulated weights will be stored in either kg or lb, depending upon the weighing unit in use. 3. If at any time the weighing units are changed, the accumulated data will be lost. 10.8.
• When the scale is at zero place a second weight on the platform. When stable press [Print] to accumulate the weight. The display will show "ACC 2" for 2 seconds and then show the new total. • . • Continue until all weights have been added. This can continue for up to 99 entries until the capacity of display is exceeded. • To view the total in memory press the [Print] key when the scale is at zero.
10.8.2 Automatic Accumulation When the scale has been set to Automatic Accumulation the value is stored in memory automatically. • Place a weight on the platform. The beeper will sound when the scale is stable indicating the value is accepted. Remove the weight. • The display will show "ACC 1" and then the total in the memory before it returns to zero. Adding a 2nd weight will repeat the process.
11 RS-232 SPECIFICATION The GFK indicator is supplied with bi-directional RS-232 interface as standard. The scale when connected to a printer or computer outputs the weight with the selected weighing unit through the RS-232 interface.
