„

M 704 GB

Check the electrical wiring and cables for recognisable damage before putting the
device into operation.
Replace damaged wiring and cables, before that, do not take the device into
operation again.
Let damaged or broken plugs be replaced by an electrician.
Do not pull the plug from a socket at the flexible cable.
Covering electrical motors can cause high temperatures so that fire results and the
working means can break down.

1.5 Maintenance

Before working on the electrical installation always disconnect power
supply!

The assembly may only be carried out by persons who are competent and can
guarantee a proper repair because of special training or their knowledge and
practical experiences with the unit.
Repair, maintenance and cleaning operations as well as the removal of functional
disorders may generally only be carried out when the drive is turned off and the
motor is in a standstill.
Only work with appropriate tools; in case of possible danger to hands, use protective
gloves.
After any repair works, the user has to check the proper functioning of the unit or
machine. He may only take the device into operation, when all protective systems
have been put into place again.
Spare parts have at least to correspond to the technical requirements fixed by the
producer of the device. This requirement can be met for example by original spare
parts.

1.6 Ordering spare parts

)

• The screw connection between silo leg and pressure plate has to be adapted to

the respective type of silo, which means that holes have to be drilled according to
the type of silo.
The size and type of fixing screws also have to be adapted to the type of silo.

4.2 Connection of the weigh bars

)

All weigh bars are connected in parallel. If the cable to the weigh bars is
not sufficiently long, all cables have to be guided into a branch box, to be
connected in parallel and to be connected to the weighing indicator by
means of a common cable.

4.3 Connection of the weighing indicator

The WP99-1 software comprises a software which can be used for silo as well as for
container scales. This software permits weighing in and metering out of a component.

Hardware requirements:

Applied software: 240 WP99-1, version 1.06, edition 29.08.96 or higher

)

When an update is carried out by a lower version after version 1.06, all
data have to be entered anew. For deleting all existing data use OPC 33.

• Install a relay which is switched from the Tx-output. This relay then switches the

contactor for the auger motor. Only charge the relay with max. 50 V AC/DC and 5
A.

• Solder a bridge above the resistance R39 on the component side of the board

(see diagram).

5 Operating instructions

5.1 Software settings

The entry for the silo scale is done via OPCode 1, which is described in the following.
This code is automatically available, as soon as the appliance No. 5 has been
entered.
To be able to use the WA99 as silo scale, the following software setting is required:
• Put DIP-switches SW3-1 to SW3-10 into OFF position.
• Put DIP-switches SW3-6(A) and SW3-7(B) into ON position and push the Reset

button.

During runup, information on the used software or the settings are indicated.

• Enter appliance No. 5 under OPC 70.
• Enter the calibration No. by means of one of the following methods:

with OPC 71, standard calibrations can be chosen

with OPC 79, manual calibration can be carried out

with OPC 86, known data of a calibration can be entered.

• Enter the filter characteristics by OPC 65
• Enter zero point under OPC 72
• Put DIP-switches SW3-6 (A) and SW3-7 (B) into OFF position and push the Reset

button.

During runup, information on the appliance No. (d = 005) and the calibration

No. (c = xxx) are indicated.

• Push Reset button to finish.

Caution

If the error message -Err95- is indicated at the end of the
runup, push the F1-button under OPC 97 (after putting DIP-
switches SW3-6(A) and SW3-7(B) into ON position and
pushing the Reset button).
Every error message can be deleted by means of pushing
the OPC-button.

)

If data have been entered by OPC, after entering this OPC it can be left
again by pushing the OPC button and it is indicated as described in 5.2.

5.2 Functions

The silo scale has different functions:

a) Weigh a predetermined weight in (U), i.e. a predetermined quantity is

weighed into an empty container, which is located on a scale.

Sign for weighing in ─┘

b) Meter a predetermined weight out (∩), i.e. a predetermined quantity is

metered out of a full container which is located on a scale.

Sign for metering out ─┘

The system to be used can be chosen by the F1-button.

c)

Weigh in a quantity up to a certain weight on the scale (r), i.e. the possibly

remaining quantity is taken into account. If this value is already reached

upon starting the weighing-in process, starting is not carried out.

Sign for considering remaining quantity ─┘

Whether this function is used, can be chosen by the F2-button.

r = with taking into account of remaining quantity

blank = without taking into account of remaining quantity

d) Meter a predetermined weight out (∩), i.e. a predetermined quantity is

metered out of a full container which is located on a scale.

Sign for considering remaining quantity ─┘

The difference to b) is that the scale does not allow a negative scale value, i.e. if the
scale indicates a smaller value than the quantity to be metered out, the error
message -Err65- is prompted.
The container then does no longer contain a sufficient quantity.

5.3 Entering the quantity to be metered in / out - OP-Code -

For example: 1500 kg are supposed to be weighed into a silo and the remaining
quantity to be taken into account.

Enter for example 1500 kg

It is supposed to be weighed into the silo.

the quantity which is metered in. During metering in, the sign flashes at the very
right of the display. If the value is zero, the display automatically changes to the
scale value.

• If the settings are not changed, metering in can directly be started by pushing the

START button.

• Starting of metering in can also be carried out over an externally connected clock

(see diagram).
