- ZERO key (ref.1): is used to reset the balance when the transpallet is unloaded and the display indicates a value near zero (for non-resetable values use the TARE key). It also serves to annul the negative tare
values. If the transpallet is correctly zeroed, the "O" LED will light up (ref. 9).
- TARE key (ref.2): pressing this key the weight of the container located on the transpallet is cancelled. When a tare is inserted, the "NET" LED will light up (ref. 11).
- MODE key (ref.3): it enables the selected functioning mode (Standard, Net/Gross) in the TECHNICAL SETUP.
- ENTER/PRINT key (ref. 4): the key for confirming.
- C - ON/OFF key (ref.5): start/stop switch.
LED Lights indicate the function states of the instrument:
- FUN light (ref. 6): if lit, indicates that the piece-counter is functioning.
- kg W1 light (ref. 8): if the LED is on, it shows the unit of measurement used and that the weight value is within the first weighing range.
- kg W2 light (ref. 7): if the LED is on, it shows the unit of measurement used and that the weight value is within the second weighing range.
- 0 light (ref. 9): if lit, indicates that the system is perfectly zeroed.
- ˜ light (ref. 10): if lit, indicates that the load is not stable.
- NET light (ref. 11): if lit, indicates that a tare is memorized.
- G light (ref.12): if it is on, the value displayed is gross load.
- Infrared signal lamp (ref.13 ): infrared signal reception sensor (optional).
This indicator allows having an additional function to be chosen from the following preset ones, function which joins the basic weighing functions - kg or lb - with tare subtraction:
To select the desired additional function, access the TECHNICAL SETUP environment.
Switch on the instrument by pressing the C button, then press TARE once, as the starting messages are displayed or while the countdown is running: after a while, the message "- tYPE -" will be displayed.
When in the TECHNICAL SETUP, the instrument keys take up the following functions:
ZERO: scrolls forward through the programming steps. In case a numeric digit is to be entered, it decreases the selected number (flashing). Once the step has been accessed, it enables scrolling through the
configurations available.
TARE: scrolls backwards through the programming steps. In case a numeric digit is to be entered, it increases the selected number (flashing). Once the step has been accessed, it enables scrolling backwards
through the configurations available.
MODE: it allows rapid positioning on the first SETUP step or, when inside a specific one, on the first parameter. In case a numeric digit is to be entered, it selects the number to be modified (flashing).
ENTER/PRINT: double function: it allows "accessing" the selected step and stores the changes made; then it moves to the following step.
C: it allows exiting a step without storing the changes made; when not inside a specific step, it allows exiting the setup. In case of changes, the instrument asks for saving instructions by displaying the message
"SAVE?": ENTER confirms, C exits without saving. When entering a numeric value, it rapidly resets the displayed value.
Scroll the various programming steps until "F.ModE" by using the ZERO or TARE keys. Press ENTER to confirm your action and access the next menu; enter the "FunCt." phase and scroll the possible configurations
up or down using the ZERO and TARE keys; press ENTER to save one of the following possible additional modes.
- STANDARD (Std): simple display operating mode, kg/lb conversion through MODE key; the selected measurement unit is indicated by the relevant led lamp.
- NET/GROSS (ntGS): simple display operating mode with MODE key carrying out the net/gross conversion. In case of set tare, by pressing MODE; the gross weight will be displayed for about 3 seconds and the
G led will flash for the same period.
ENTERING THE TARE
The tare weight can be entered in two ways:
Self weighted semi-automatic tare entering
This normal function can be summarized with a simple example:
- Turn on the instrument with the C key before positioning any weight on the forks (if the value given on the display is not exactly 0, reset it by pressing the ZERO key).
- Press the MODE key to select the weighing mode in kg or in lb.
- Position on the forks a pallet or an empty container of the same type of that one that will need to contain the pieces that will be weighed.
- Press the TARE key in order to reset the display; now all the weights will be shown net.
Note. By pressing the TARE key you will cancel any weight present on the forks and the NET light will come on.
Manual tare entering from keypad
Press TARE for a few seconds: the messages "- tM -" and "000000"; will be displayed; enter the desired value.
The set tare value will be subtracted from the loaded weight and the NET lamp will turn on.
Any new tare operation cancels and replaces the previous one.
The TARE weight value can be cancelled even with the scale loaded: simply press the C key or enter zero as the tare weight value.
Selecting tare disabled/Locked/Tare unlocked
Once the tare value has been entered - semi-automatically or manually - the display will show the tare value in negative form (TARE LOCKED) every time the scale plate is unloaded. The set value can be used
again, cancelled by using the ZERO key or replaced with a new value. It is also possible to set the instrument in such a way that it automatically resets tare values every time the scale is unloaded (TARE UNLOCKED).
In case of SELF-WEIGHTED TARE, the net weight with loaded scale can also be 0.
In case of MANUAL TARE, the net weight with loaded scale should be at least 2 stable divisions.
Access the TECHNICAL SETUP F.Mode>>tArE step, select "unLoCK" to UNLOCK, "LoCK" to LOCK or "diSAb" to disable the tare function. Press ENTER to confirm.
CALIBRATION
The transpallet has been calibrated by the Manufacturing Firm and this guarantees optimal precision and stability. However, if the user verifies an indication error with his sample weight, he can eliminate it with
the following procedure:
NOTE. PAY VERY CAREFUL ATTENTION TO SCROLL THE VARIOUS LINES WITHOUT VARYING THE VALUES SET BY THE MANUFACTURING FIRM IN ORDER TO NOT INCUR FUNCTION PROBLEMS. IF, BY
ERROR, ANY OF THE VALUES SHOULD BE CHANGED, IMMEDIATELY TURN THE INSTRUMENT OFF WITH THE C KEY, IN ORDER TO NOT SAVE THE MODIFICATIONS WHICH YOU HAVE ACCIDENTALLY
ENTERED.
Hold C key pressed for a few seconds to switch on the instrument, then access the TECHNICAL SETUP field. Press TARE keys as the first messages - battery charge level "bt XXX", software version "XX.YY.ZZ"
etc. - are displayed or during the countdown; then release it. The message "tYPE" will be displayed - we advise only procedure experts to access this field.
Scroll down the various phases displayed using keys TARE until you reach line "SEtuP"; press ENTER repeatedly to enter phase SEtuP>>ConFiG>>nChan. Press keys Zero and Tare again until you reac h phase
"GrAV". The first setting to check and possibly correct is the "g" value (m/s 2 ), of the gravity area used "GrAV" (DEFAULT "9.80655"); press ENTER, use keys ZERO, TARE and MODE to set the "g" value corresponding
to the area of use of the pallet truck and press ENTER to confirm selection. The display automatically scrolls down to the next phase "Calib" (scales calibration); press ENTER, scroll down the various steps using
keys ZERO and TARE until you reach phase "CALib.P", press ENTER to enter phase "EquAL"; at this point a menu containing the following sequence of items is displayed:
1) "Reset?" - Press ENTER to reset.
2) "Eq 0" - Equalizing zero: press ENTER key with the pallet truck unloaded.
3) "Eq 1" - Equalizing cell A (see fig. E): place a calibration sample on the cell, press ENTER then unload weight again - we advice to use a 100 kg sample.
4) "Eq 2" _ "Eq 3" _ "Eq 4" - Equalizing cells B - C - D: repeat operation with the same weight on every single cell.
In case an error occurs during any equalization steps, the message "ERROR" appears on the display and the instrument produces a sound signal.
Once the equalization procedure is over, the message "EQ OK" is displayed, the instrument produces 3 sounds and exits the equalization submenu, moving to the next step: "n tP", number of calibration points.
A) Press ENTER to select the number of calibration points "1" o "2"; press ZERO, TARE keys to modify selection and ENTER again to confirm. In case 2 known weights are available, it is advisable to use 2
calibration points in that weighing will be more precise.
B) "tP 0" - Calibrating the scale zero: press ENTER with the pallet truck unloaded to carry out the calibration of the scale zero.
C) "ddt1" - Setting the first calibration point: press ENTER, set value of the first sample by using ZERO, TARE keys and MODE - use preferably a 1000 kg weight - then confirm by pressing ENTER. The display will
automatically move to the next string "tP 1".
D) "tP 1" - Calibrating the first point: place the first known sample having the same value as programmed in the "ddt1" step onto the forks, wait until stabilization is complete then confirm by pressing ENTER.
E) " ddt2" - Setting the second calibration point: press ENTER, set value of the second sample by using ZERO, TARE and MODE keys - use preferably a 2000 kg weight - then confirm by pressing ENTER. The
display will automatically move to the next string "tP 2".
F) "tP 2" - Calibrating the second point: place the second known sample having the same value as programmed in the "ddt2" step onto the forks, wait until stabilization is complete then confirm by pressing ENTER.
G) FINAL DATA STORAGE AND EXIT MENU: Provided everything so far has been done correctly, if you press down key C protractedly, the instrument will ask you whether you wish to save by displaying the
question "SAVE?"; press ENTER to confirm saving or C to exit without saving.
BATTERY (16.8)
This transpallet is fed from 4 AA batteries. It is necessary to replace the batteries (alternatively recharge them in case of the rechargeable kind) each time the signal "LO-BAT" (low battery) appears on the display
(Note: before the battery runs out of current, the instrument will indicate this condition by flashing the "kg" LED light for 3 minutes).
For the replacement of the battery, extract the compartment on the front (ref. 8 in fig.B) and replace the discharged batteries.
