DOL 192 12-20 Egg Counter
4 Technical User Guide
1 Product description
The DOL 192 Egg Counter is intended for automatic counting of eggs on a conveyor belt. It is touch-free and
functions with the aid of an infra-red light. This reduces the risk of injuries, contamination and ensures an unres-
tricted flow of eggs on the conveyor belt.
The DOL 192 Egg Counter is available in 7 different variants (2 small 24 V DC egg counters and 5 large 230 V
AC egg counters), so that it fits the conveyor belt.
• DOL 192 12 cm scan width 120 mm, 24 V DC is suitable for counting eggs on longitudinal conveyor belts.
• DOL 192 20 cm scan width 120 – 200 mm, 24 V DC is suitable for counting eggs on longitudinal conveyor
belts.
• DOL 192 30/40/50/60/75 cm scan width 223 – 760 mm, 230 V DC are suitable for counting eggs on con-
veyor belts that collect eggs from more than one longitudinal conveyor belt.
The DOL 192 egg counter provides 1 pulse per egg to a DOL 53X house controller (version 2.2 or newer).
The DOL 192 Egg Counter is accurate to at least 99.5% when installed correctly.

3.3 Mounting on conveyor belt
The egg counter is mounted on the supplied bracket directly over the conveyor belt.
Ensure that the bracket does not cover the sensor.
In order for the egg counter to be able to count optimally, it must be placed so that the eggs are unable to roll or
move sideways. Eggs that move around may be counted more than once.
The eggs must not be able to move backwards when the conveyor belt stops.
Sharp light, especially sunlight and fluorescent light, may affect the accuracy of the egg counter. Place the egg
counter so that it is not exposed to direct (sun) light, or ensure that it is protected from sources of light.
In the event of too much light, the red LED will turn on. (DOL 192 12-20)
In the event of too much light, warning # 4 (DOL 192 30-75) will appear on the display.

3.3.2.1 Adjusting the scan width
Conveyor belt
Scan width
If the scan width of DOL 192 20 cm is wider than the width
of the conveyor belt, some of the infra-red sensors should
be turned off.
Set the dipswitch on scan module 2 (slave), see table be-
low.
The scan width can be adjusted in steps of ≈11 mm.
The distance between the last (used) infra-red sensor and
the edge of the conveyor belt should be approx. 14-20 mm.

4 Installation Guide
When the power supply to the egg counter is turned on, the egg counter runs a self-test for 2 seconds. It is sub-
sequently ready to count eggs. The green and red LED’s on the front will light up (= orange) during the self-test.
The red LED subsequently turns off (the green LED remains on).
The egg counter is connected as an electrical pulse generator to a production controller. An electrical pulse is
generated to the output of the egg counter when an egg is detected.
The egg counter has been fitted with a standby input. The standby input must be activated when the conveyor
belt under the egg counter is stopped. When the standby input is active, the orange LED turns on and the egg
counter ceases to count eggs.
The egg counter is always ready to count eggs if the standby input is not connected. This may have a negative
effect on the accuracy of the egg counter however.
We recommend using the standby input at all times in order to ensure maximum accuracy.
4.1 Electrical connection
Qualified personnel in accordance with the applicable national and international standard EN
60204-1 and any other EU standards that are applicable in Europe must perform installation, ser-
vicing and troubleshooting of all electrical equipment.
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 provided.

The DOL 539/535’s installation menu shows precisely which terminals
the egg counter should be connected to. The ground terminal is not
displayed. If Pull up is displayed, a 10 KΩ resistor must be installed.

Setup | Show connections
4.3 Cable Plan
Use low voltage cables for electrical connection of egg counters (max. length of 100 m from controller to egg
counter).
The length of the signal cables should be limited as much as possible.

5 Maintenance Instructions
5.1 Cleaning
The egg counter is maintenance-free but should be kept free of litter and dirt.
Clean the product with a cloth that has been wrung out almost dry in water and avoid using:
• high-pressure cleaning
• solvents
• corrosive/caustic agents
The egg counter should preferably be cleaned in standby mode in order to prevent counting errors.
Ensure that the egg counter is not damaged by high-pressure or steam cleaning. The egg counter should be
turned on (standby mode) during cleaning in order to heat the cabinet from the inside and avoid drawing humid-
ity.
5.2 Recycling/Disposal
Products, which are suited for recycling, are marked with a pictogram showing a refuse bin that is
crossed out. See illustration.
It must be possible for customers to deliver the products to local collection sites/recycling stations in accordance
with local instructions. The recycling station will then arrange for further transport to a certified plant for reuse,
recovery and recycling.
