Section 1. Unpacking and Installation
Your Doran Model 4200 or 4100L is ready to unpack, install and put into use. These
models (if ordered with a platform) have been carefully calibrated and packed at our
factory. If you observe any shipping damage to the carton, immediately notify your shipper
- Doran insures all shipments, but all damage claims must be made directly to the shipper.
There are 3 different 4200 types that can be ordered. The internal electronics and the front
panels are all the same, but accessing the main board for setup and calibration is different
for the 3 types. Whenever a procedure depends upon the enclosure type in this manual,
the type is specified in the instructions. The 3 enclosures are pictured below.
In addition to the 4200 models, this manual covers the Model 4100L, which is a "Legal for
Trade" version of the Model 4100 Checkweigher. The 4100L is identical to the 4200
electronically, but is different in the display and front panel. See Section 9 for information
on the 4100L.

UNPACKING
Before proceeding to unpack your Model 4200, please note that although it is a highly
durable industrial scale indicator, it is also a sensitive weighing instrument. Normal care
should be taken when handling and using the indicator. Improper handling or abuse could
be damaging and result in costly repairs that may not be covered by the warranty. Please
observe the following precautions to insure years of trouble-free service from your Model
4200.
* DO NOT drop the scale indicator or platform.
* DO NOT immerse the scale indicator or platform.
* DO NOT drop objects on the platform.
* DO NOT pick up the scale platform by the "spider".
Carefully remove the Model 4200 from the shipping carton. Be sure to retain the shipping
carton and all packaging material in case reshipment is required.
INSTALLATION
4200 Tower: Models with 10" x 10", 12" x 12", and 12" x 16" platforms are shipped in
one piece (fully assembled). When unpacking models with 18" x 18", 18" x
24", and 24" x 24" platforms, note that the scale is shipped with the indicator
column detached from the weighing platform. To attach the indicator column
to the platform, first locate a suitable area at the edge of a table or bench that
is taller than the indicator column assembly. Lift the indicator off the platform
and set it aside. Note that the indicator and platform are connected by a 5'
cable; be careful not to pull on this cable.
Remove the platter from the weighing platform and set it aside. Invert the
platform and set it such that the side holding the four indicator column
mounting bolts is at the edge of the table. Remove the four mounting bolts
from the bottom of the mounting holes. Reinstall and tighten the four
mounting bolts. The indicator column mounts to the support plate with 4
1/4"-20 x 1/2" hex head screws. Lift the indicator column and point it down
towards the floor with the display facing the platform. Align the 4 mounting
holes in the base of the column with the corresponding 4 holes in the support
plate. Install and tighten the 4 hex head screws.
