Assembly (the references to pages and items relate to the replacement instructions drawing, Pages 5-13)
Assemble in reverse order of disassembly.
Please note the following points:
1. Glue on the mat (Page 11)
Mounting the following parts before you glue on the mat:
The 4 rubber elements and washers (Item 11.3) with the screws (item 11.5).
The platform reinforcing plate (item 11.2) with the screws (item 11.6) and the nuts and washers (item
11.1)
The mat is attached with a special double-sided adhesive tape.
2. Fitting a new load cell (Page 6)
After replacing load cells, the scale must be readjusted and calibrated if required. For adjustment, please
follow our calibration instructions, document no. No. 30-34-00-672.
3. Holder for mains socket and bubble level (Page 6)
If you have dismantled the holder or fitted a new bubble level, the scale must be tested again and
readjusted and calibrated if required.
4. Housing for evaluation electronics and battery pack (Page 7)
Behind the cable gland directly in the housing, the mains socket cable must be winded on a ferrite ring
(Page 8, Item 8.12). The cable must be pulled through the ring 5 times.
When soldering the load cell, mains socket and rechargeable battery cables onto the PCB (Item 7.7)
make sure the cables are allocated correctly to the soldering pads. Solders without any fluxing agent
residues must be used.
5. Display housing (complete with joint) (Page 12)
If the complete unit is inserted into the column tube, make sure the bearing bush (Item 12.15) is fitted in
the correct position to ensure that the display can be turned to the right angle (see drawing).
6. Assembling the display housing (Pages 12,13)
Prior to assembling, the joint and the carrier unit (Page 12, Items 12.15 to 12.22) must have been
completely assembled.
Fit the cable (Page 12, Item 12.12):
Thread the cable through the central opening in joint connection and housing
Plug it into the PCB (Page 13, Item 13.7).
Place the cable in the housing behind the plastic pins so that the drawer and the battery compartment
can still be moved after the housing has been assembled.
7. Joint and locking unit (Page 12)
Cable (Item 12.12):
A new cable should be adjusted to the required length and tied up with cable ties (see the original
cable).Setting the joint:
Screw the threaded axle (Item 12.11) so far into the thread of the bearing block (Item 12.6) that the
bracket (Item 12.9) can be turned easily and without any play.
Screw the lock screw (Item 12.5) against the threaded axle and check that the joint does not have any
play. Readjust the threaded axle and lock it in position if required.
The thread of the bolt (Item 12.4) and the knurled nut (Item 12.1) should be secured in a medium-tight
position with a screwlock.
