1.Introduction
This instrument is a precision digital indicator using the latest Sigma-Delta analogue to digital
conversion technology to ensure fast and accurate weight readings.
Figure 1: Weight Indicator
The setup and calibration of the instrument are digital, with a non-volatile security store for all setup
parameters.
The instrument may be operated from 4.8V, 7.2V, 9.6V, 12V or 24V batteries or a DC power source
from 7V to 24V. There is a soft power on/off function that retains memory of the indicator’s state.
Once an instrument is turned on it will automatically start up again if the external power is
interrupted.
The instrument is fitted with opto-LINK communications as standard. This allows a temporary
isolated communications link to be established with a PC using an opto-LINK cable, which enables
software upgrades and the use of computerised setup and calibration via the Viewer software. Refer
to opto-LINK (Optional) page 16 for more information.
The instrument comes with five different firmware types (K342, K344, K346, K354, and K356).
FACTRY.APP.ID can be used to select desired firmware. Then licence code should be entered using
FACTRY.L.CODE. Refer FACTRY menu page 41 for more information.
1.1. Overview
This instrument provides ZERO and TARE functionality as well as more setup options (e.g.
serial and setpoints) and printing functionality.
It also supports special functions (e.g. peak-hold, averaging, counting, etc.), via the user
definable <FUNCTION> key. It is equipped with an NVRAM store to ensure day-to-day
operating settings (e.g. ZERO, TARE,CLOCK, etc.), are retained when power is removed.
(NVRAM only supported in the K35* models)
This instrument has two isolated transistor outputs with status display on the front panel as
well as the RS-232 communications port that can be used for printer driving or connection to
a remote display or PC. There is a built-in clock for date-stamping printed outputs.

3. Installation
3.1. Introduction
The following steps are required to set up the indicator.
•Inspect indicator to ensure good condition.
•Use connection diagrams to wire up load cell, power and auxiliary cables as required.
•Use the panel mount template provided for hole locations.
•Connect Power to indicator and press <POWER> key to turn the instrument on.
•Refer to the section page 31 for information on configuring and calibrating the instrument.
•To turn instrument off press and hold <POWER> key for three seconds (until display
blanks).
3.2. General Warnings
•Indicator not to be subject to shock, excessive vibration, or extremes of temperature
(before or after installation).
•Inputs are protected against electrical interference, but excessive levels of electro-
magnetic radiation and RFI may affect the accuracy and stability.
•The instrument should be installed away from any sources of excessive electrical noise.
•The load cell cable is particularly sensitive to electrical noise and should be located well
away from any power or switching circuits.
•For full EMC or for RFI immunity, termination of cable shields and correct earthing of the
instrument is essential.
•Indicator and load cell cable are sensitive to excessive electrical noise. Install well away
from any power or switching circuits.
3.3. Electrical Safety
•For your protection all mains electrical hardware must be rated for environmental
conditions of use.
•Pluggable equipment must be installed near an easily accessible power socket outlet.
•To avoid the possibility of electric shock or damage to the instrument, always switch off or
isolate the instrument from the power supply before maintenance is carried out.
3.4. Cleaning
•To maintain the instrument, never use harsh abrasive cleaners or solvents. Wipe the
instrument with a soft cloth slightly dampened with warm soapy water.
3.5. Panel Mount Template
Use the panel mount template for drill hole locations. The template indicates positions for the
two 4mm mounting screws through the panel. Also displayed on the template is the position
of the rectangular hole that should be cut to allow for the connection of cables. The template
supplied with the indicator allows for front or rear machining of the panel.
