unit power cord must be plugged into a grounded 3 - wire polarized AC wall socket. All normal
wiring and grounding precautions should be observed, including use of a "clean" AC power
line.
SCALE WIRING:The unit is equipped with cable gland entry for load cell cable insertion and
internal (pluggable) terminal strip for 4 / 6 wire connection. Remove sense jumpers P11-8/7,
P11-6/5 for six wire.

SETUP ACCESS
To access instrument configuration, calibration or to enable options, depress the “Zero” key for
five seconds.
The Audit Trail counters (“Pxxxx” and “Cxxxx”) are displayed first followed by access code
request (“AC?”). The initial factory setting is “0000” which can be entered with four steps of the
“Gross/Net” key (“AC0000”) and “Print”. If no entry is made, instrument returns to operate
mode.
The access code can be changed to any four digit combination during setup exit when display
again shows “AC?”.
The “Check” key provides the software version “V 1.XX” followed by the display test routine.
Use the “ENT” key to advance to the keyboard test and to exit tests.
After entry, use the “Tare Recall” key to select a main menu; configuration (“SEL.CFG”),
calibration (“SEL.CAL”), or options (“SEL.OPX”) and “Start/Stop” to back step.
The “Gross/Net” key enters selected menu and is used to step through sub categories.
Individual parameter selection is made with the “Tare/Recall” key, which then steps through
the parameter choices (“Zero” key back steps within the menu).
The “ENT” key is used at any point to “back” up from categories to menus and to “save?” and
“AC?” and exit.
During the exit steps, if changes were made, the display is “save?” with alternate “no”. To save
changes, use the “Units” key to select “yes” and “ENT” to exit.
Calibration numeric entries are entered directly followed with the “ENT” key.
5
Front panel access is inhibited if conventional “sealing” is applied by
setting jumper J1-1 in the B position. The board mounted “CAL” button is
then used for access.

Remote Serial Display (RSD) Option
In RSD mode the instrument can be set to work with another unit as a “remote” either as the
main or the slave unit. Communication is pre-set for channel two only on both units.
(RS232, 9600, 8, none)
When in remote mode, re-access to the following selections requires using the internal “cal”
switch.
Remote unit can have full or partial control of the main unit. Devices are available to replace
the cable for wireless communication.

CALIBRATION: “SEL.CAL” Use Gross/Net to enter the menu indicated by a flashing “C” on
the left and live weight is displayed. Scale zero (dead load) or adjusting span (single or multi-
point) are independent. Therefore either can be done and repeated as necessary before
exciting calibration. If an error has been made, exit without “storing” will return to prior setup.
KEY (FUNCTION) DISPLAY Definition
(Live weight 123 lb) “C”__123 Cal mode scale reading
Zero (acquire dead load) “------“ to “C___0.0” acquires new dead load
(live weight 5000 lb) “C”__4995 Scale reading with load
Enter numeric value directly:
(Adjustment complete) 005000 adjusted value
Then ENT:
(adjust span) “------“ to “C” 5000 displays new span
Repeat as required then ENT to exit CAL
“Save ?” “No” or “Save ?” “Yes” use Units to select and ENT to store “yes” with changes or
“no” to exit without changes.
Continue with ENT to “Ent AC” which allows access code change by entering a new four digit
code and ENT or ENT with no entry to maintain current password.
Option 5 Ten point calibration: Allows up to 10 span points (pt1…….pt10). Zeroing the scale
clears the existing values. Points are assigned incrementally with error indication if the addition
is not above the prior point or exceeding scale capacity.
Filter selection included for rolling or box averaging.
5.1 OFF, On Enable 10 point span
5.2 A, b A : Rolling average
B : Box average

Weight errors of any kind (e.g., ol, ul, etc) will de-energize all relay outputs and abort a
batch if one is in progress.
Four outputs are available to use as two setpoints with main and fast feed, single
setpoint main and fast feed plus tolerance and zero band. Also Pre-Act can be applied
to the main, for material in-flight compensation.

Option 6 Totalizer: Operates with “print” function in normal mode or batch mode.
In normal mode, current value is added to the totalizer with each “Print” command. The
reset band is used to inhibit a double add when not in Batch Mode.
View the Total with the “2” key and during the display (AC..XXXX), the “Print” key is
used to print the total, the “Ent” key returns to weigh mode.
The “Clear” key is used to clear the totalizer by first changing the message from
“Clr.ACC…no” to “Clr.ACC…yes” with the “Units” key and “Ent” to complete. A
“Cleared” message is provided for conformation.
Note: Totalizer works with port 1 only and the “Print” key is disabled when Batch Mode
and Totalizer are both enabled.
OPTION 4: Weigh – In / Weigh – Out
