Safety Summary

All safety related regulations, local codes and instructions that

appear in the manual or on equipment must be observed to ensure
personal safety and to prevent damage to either the instrument or
equipment connected to it. If equipment is used in a manner not
specified by the manufacturer, the protection provided by the
equipment may be impaired.

Do not use this unit to directly command motors, valves, or

other actuators not equipped with safeguards. To do so can be
potentially harmful to persons or equipment in the event of a fault
to the unit.

FRONT PANEL

JUMPER LINK FUNCTIONS

The indicator has three jumper links that must be set prior to operation.

These are:

•  

Input Range Select

Select either 

±

24 mVDC or 

±

240 mVDC range. Select an input range

high enough to avoid input signal overload. Program the input range to
match jumper selection.

•  

Bridge Excitation Select 

Select either 5 VDC or 10 VDC bridge excitation.

•  

User Input Source or Sink Select

FRONT

KEY FUNCTIONS

TARA KEY FUNCTION 

The 

TARA

key selects among the Gross, Net and Tare weight displays.

Corresponding panel enunciators illuminate to indicate the selected display. If
Tare weight = 0, the indicator prevents selection of Gross and Net weight
displays. Within the program menu, this key quits programming and returns to
display mode.

PAR KEY FUNCTION

The 

PAR

key allows access to the configuration parameters. The function of

this key can be locked.

Within the program menu, this key stores the active parameter and indexes to

the next.

During Digital Tare, this key stores the tare weight value keyed in.

KEY

The

(Tare In/Tare Out) key both acquires and clears the Tare weight

value. The function of this key can be changed by setting the F1 function
parameter. For data entry, this key is also used to increment a parameter value.

KEY

The

key (Zero) re-zeros the Basic and Gross readout displays. The

function of this key can be changed by setting the F2 function parameter. For
data entry, this key is also used to decrement a parameter value.

Key

The

key (Print) causes a Print Ticket output. Prints occur regardless of

scale motion. The function of this key can be changed by setting the RST
function parameter. For data entry, this key is also used to scroll a parameter
value by x1000 factor when held with the Tare and Zero keys.

DISPLAYS

BASIC WEIGHT DISPLAY

The Basic Weight Display provides a direct indicator readout. The display

occurs when the Tare Weight =0. 

BRUTTO/GROSS WEIGHT DISPLAY

This Display indicates the Brutto/Gross weight. It is only possible to select

this display mode when Tare > 0, otherwise it is locked out by the indicator.
“B/G” illuminates for this display mode.

NET WEIGHT DISPLAY

This Display indicates the Net weight. It is only possible to select this display

mode when Tare > 0, otherwise it is locked out by the indicator. If after the Tare
Weight is set > 0, the Net Display is selected by the indicator. “NET” illuminates
for this display mode.

TARE WEIGHT DISPLAY

This Display indicates the Tare weight. When this display is selected, it is

possible to directly key-in the Tare Weight value. “T” illuminates for this display
mode. It flashes during tare weight key-in entry.
