1.1 Documentation

The weighing terminal IND690-… comes supplied with a CD containing all the
documentation on the weighing system IND690.
These operating instructions describe the operation and configuration of the
application software IND690-Control.
The basic information for working with the weighing terminal IND690-... can be
found in the operating instructions IND690-Base.

1.2 Introduction

The IND690-Control supports 5 different applications that are selected and set in the
master mode: CHECKING, CLASSIFYING, WEIGHING, WEIGHING 1+1 and TARGET
TOTALIZING. These applications can be run in the fully automatic or semi-automatic
mode. The semi-automatic mode permits remote operation.

1.3 FULLY AUTOMATIC and SEMI-AUTOMATIC MODE

The fully automatic and semi-automatic modes differ in the manner in which the
weighing sample is transported to and from the weighing platform: In the fully
automatic mode via an automatic conveyor system, in the semi-automatic mode
manually.

1.3.1 Fully automatic mode

The weighing samples are transported onto the conveyor belt of the weighing
platform via a supply belt, weighed and transported away at predefined time
intervals. The IND690-Control controls the conveyor system via the 8-690 relay box
(for instructions on connecting the relay box, see section

6.1).
For the fully automatic mode, the setting FULLY AUTOMATIC MODE must be selected
in the OPERATING MODE master mode block.

Applications of IND690-Control

Operating instructions 22012846B 08/08 5

IND690-Control

The conveyor system can be started and stopped as follows:

• manually via foot switch or hand switch,

• via interface commands, see application block 306 in section 3.

1.3.2 Semi-automatic mode

The weighing samples are transported manually onto the weighing platform, e.g. on
a monorail-suspension weighing platform, weighed there and then transported away
again manually. With a suspension monorail, blocking flaps on the transition to the
weighing rail only permit one transport direction. The blocking flaps are controlled by
the IND690-Control.
For the semi-automatic mode, the setting SEMI-AUTOMATIC MODE must be selected
in the OPERATING MODE master mode block.

Remote operation In the semi-automatic mode the IND690-Control can also be remote controlled with

"electronic fingers", see section

1.9.

1.4 CHECKING application

The IND690-Control checks whether the weight of a weighing sample matches a
specified target value with freely definable tolerances.

Prerequisite

The CHECKING application is set in the master mode.

1.4.1 Function keys

The function keys of the IND690-Control are assigned the following functions in the
CHECKING application:

➜ Press the ITEM key.

Then manually enter the start and stop value of the item counter via the keypad.

When the function keys are otherwise allocated

➜ Press the cursor keys < or > repeatedly until the function key assignment shown

above appears.

CAUTION

Danger of injury when pressing buttons which start and stop the conveyor system or
control the flaps!

➜ Before pressing these keys, make sure that no one is in the area of moving

system parts.

Notes

When TOLERANCE CHECK ON is set in the master mode,

• only weight values of the class GOOD are totalized.

• the conveyor system stops in the case of weight values outside the tolerances.

If the weight value is improved by adding to or deducting from the weighing
sample so that it lies within the tolerance limits, the conveyor system continues to
feed.
