1 Product description

During the silo weighing process, a silo load cell registers the weight of the silo content and transmits it to the

DOL 199 silo weighing box. The DOL 199 converts the weight to digital signals and sends them to the controller

using CAN bus communication.

You can connect up to four silos to the DOL 199 silo weighing box. A silo has up to eight legs and a silo load

cell is placed under each leg. The DOL 199 can be connected to a total of four silos.

(B) Silo weighing box

The DOL 199 is fitted with one silo load cell

as standard and one silo can be connected.

The DOL 199 can be extended with three

silo load cell modules, so that three extra si-

los can be connected.

(D) Connection box

The connection box is used for extending

cables from the silo load cells to the silo

weighing box. The silo load cells are con-

nected in parallel when there are more than

four of them. (SKOV A/S does not supply

the connection box).

4 Installation guide

4.1 Electrical connection

Installation, servicing and troubleshooting of all electrical equipment must be carried out by quali-

fied personnel in compliance with the applicable national and international standard EN 60204-1

and any other EU standards that are applicable in Europe.

The installation of a power supply isolator is required for each motor and power supply to facilitate

voltage-free work on the electrical equipment. The power supply isolator is not included.

4.2 Cable routing

In order to prevent water from running into the silo

weighing box via cables and screwed connections, the

cabling must be made so that water does not gather

around the cable in the gasket of the screwed connec-

tion.

Supply cables

Silo load cell / extension cable

1 m

To avoid interference, the silo load cell / extension flex

must be separated from the power cables. Distance

must be at least 1 m.

The DOL 199 silo weighing box is controlled by the CAN bus communication. To

ensure secure communication between the boxes, it is important that the CAN ter-

mination jumpers are set correctly.

If the DOL 199 silo weighing box is the last node in the CAN bus communication,

the jumper must be set to (ON).

4.7 Electronic silo weigher calibration

See the menu Technical | Calibration | Production | Silo | Silo.

Start calibration by setting the Calibrate/Set tara to Calibrate.

Enter the current weight in the silo in Calibration tare amount.

Enter the weight available for the calibration (Calibration load amount).

The more weight that is available, the more precise the calibration is. Min.

100 kg.

Place the calibration weight on the silo.

Wait until it is stable.

The calibration state changes to: Ready to end calibration

Select Finish.

If there is uncertainty about the silo content (Calibration tare amount), it

can still be calibrated and the menus continuously show how much of the

feed is being used. However, the indication of the silo content may be in-

correct.

It is possible to set the calibration tare amount at a different time when

you know the exact contents of the silo. You do not have to use calibra-

tion weights for calibration and subsequently correct the entry; instead

you set Calibrate/Set tare to Set tare and the known silo weight is en-

tered at .

Increase the value of Weighing stable, if the weight is not stabilized.

This should only be relevant if the silo is influenced by outside conditions, such as strong wind. The elec-

trical installation should be checked, if the silo is not stabilizing under normal conditions.
