First display test is accomplished which includes following sequence:
All digits are lit for 1s. Then all digits are turned off for 1s.
Through display „Weight” passes a sign “Gineers”. The sign moves from right to
left, moving through digits in every 0.3 seconds. After the sign passes all digits serial
number of G5102 is showed for 1 second, then firmware version.
Then G5102 shows scale type and capacity – on display „Weight” will be written
„G xxxx”, where хххх is a number showing scale nominal capacity.
Indicator starts checks for initial zero position – compares saved zero position
from calibration with current measured zero position. If difference between two values is
in correct range indicator enters in normal mode of operation, showing measured
weight. If current measured zero position is out of range (±10% from full capacity), on
display „Weight” will be written error – “-Hi-“ (initial value bigger with above 10%
from range) or “-Lo-“ (initial value smaller with below 10% from range).
If everything is normal scale enters in normal mode of operation. Now on display
„Weight” user sees value of measured items/products in units g/kg/t – according to
front panel label.
Loads on the platform are normal to be put on it gracefully, if user does not want
to replace sensors often. For G5102 this does not have significant matter, just stable
position will be achieved for higher period of time.
4. Connecting serial interface RS-232
Electronic unit G5102 is equipped with standard serial interface, type RS-232C.
This interface can be used for sending weigh values to external cash register or personal
computer. If working with PC special software from Gineers can be used or we can
supply data protocol to who is interested in reading weight from G5102 with its own
software.
A standard cross null-modem cable is used, which in this case means:
CANNON DB9 male G5102 CANNON DB9 male PC
2 pin Æ3pin
3 pin Æ2pin
5 pin Æ5pin
If physical connection layer is for RS-485 protocol, unit G5102 can control
RTS line of connected 485<->232 converter - pin 7 of DB9 male connector.
5. Mounting
Normally there are two ways to position G5102 unit:
On a horizontal surface without any additional efforts;
Vertical mounting on a wall
On a horizontal surface there is not mounting whatsoever – unit is directly placed
carefully on the surface.
