1 Product description

DOL 98S-20 and DOL 98S-70 poultry scales can handle poultry weighing up to 20/70 kg with outstanding preci-

sion.

DOL 98S-20 and DOL 98S-70 are a hanging scales that can be used together with production controllers for au-

tomatic weighing of poultry.

Since the platform is suspended from a wire cable, it can easily be removed for cleaning. The platform itself

does not contain any electric parts and can thus be cleaned with a high-pressure cleaner.

6 Installation Guide

6.1 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.

7 Placement and installation of scale

• Fix the position of the scale upon electrical Installation.

• Choose a neutral position in the house.

• It should be located between feed and water lines but not too close to the service room.

• Birds should not get disturbed by noises or people entering the house.

• Make sure that the scale is not located directly in the area of air intake or outlet openings.

Do not expose the scale to blows and strikes or high traction forces exceeding 20 kg

(DOL 98S-20) or 70 kg (DOL 98S-70). Do not step on the scale!

If there are zones with different climatic conditions in the house, or the uniformity of

the flock is not very good, the total weight of the flock may differ from the individual

weight per animal as displayed by the scale.

The height from the ground of the platform is of decisive importance for the number of weighings per day.

In general, it should be adjusted as low as possible. Pay attention that the amount of litter increasing dur-

ing the growing period does not come into contact with the platform.

Take into consideration that in mixed growing, male birds are heavier and thus more passive than female

birds. Experience has shown that such birds do not climb the platform as frequently if it is placed too high.

This might falsify the estimated average weight.

If multiple scales are placed in the same house, it is important that these a not mixed up when cleaning.

Put marks on the scales to ensure that each is connected to the same connector after cleaning.

8 Manual calibration of DOL 98S-20

The scale must be calibrated after installation. The scale should be calibrated at least once a year.

Connect the scale and wait for minimum 30 min-

utes at the service temperature before calibration.

1. Clean the scale of litter and dirt.

2. Remove the lid from the load amplifier.

1. Make sure the scale is empty (0 kg).

2. Push and hold the button until the green LED begins to flash quickly.

3. Then let go of the button. Wait until the green LED begins to flash slowly.

4. Place 5 kg on the scale.

5. Push the button and hold it until the green LED begins to flash quickly.

6. Let go of the button and wait until the LED stops flashing.

7. Remove the weight again.

If during calibration, the red LED has been flashing, an error has occurred during the calibration process.

The calibration should therefore be repeated.

Put the weight/weights on the scale in the same way each time.

8. Mount the lid on the load amplifier again.

9 Manual calibration of DOL 98S-70

The scale must be calibrated after installation or repair. The scale should be calibrated at least once a year to

ensure that it works according to specifications.

The output voltage for the scale is adjusted on the load amplifier placed on the load cell in the bird house.

The voltage must be 0.5 volt.

1. Make sure the scale is empty (0 kg).

2. Adjust the output voltage to 0.5 V by means of the

multitrimmer, see the picture.

10 Maintenance

• The scale should be kept free of litter and dirt.

• The scale should be calibrated at least once a year.

The scale is not subject to daily attendance. However, it is important that the settings made in the controller con-

cerning weighing of poultry are correct. Otherwise, the average weight of the birds will not be calculated cor-

rectly.

• Check on a regular basis that the number of approved weighings is not less than 100 birds each day.

If the number of weighings falls to less than 100, it may be a result of the settings for search limits and reference

weight in the controller not being correct. See also the User's Manual of the controller.

10.1 Batch End - Catching

• Before starting to catch the birds, raise the weighing platform to the ceiling.

• It is important to winch the wire to the ceiling by means of the suspension device for feed and water lines in

order to prevent damages.

• After finishing the growing period, keep the cleaned platform in a dry place.

To prevent damage to the load cell upon lowering the system do not tie the wire to the feed or water

lines.
