1.1 Organization of safety notices
Safety notices in this manual are organized as follows:
Safety notice Description
Danger! Disregarding these safety guidelines and notices can be
life-threatening.
Warning! Disregarding these safety guidelines and notices can result
in severe injury or substantial damage to property.
Information! This information is important for preventing errors.
1.2 Safety Precautions
This product is UL listed as open type process control equipment. Danger!
If the output relays are used past their life expectancy, contact
fusing or burning may occasionally occur. Always consider the
application conditions and use the output relays within their rated
load and electrical life expectancy. The life expectancy of output
relays varies considerably with the output load and switching
conditions.
Danger!
Loose screws may occasionally result in fire.
For screw terminals of relays and of power supply, tighten screws
to tightening torque of 0,51 Nm. For other terminals, tightening
torque is 0,19 Nm
Warning!
A malfunction in the Digital Controller may occasionally make
control operations impossible or prevent alarm outputs,
resulting in property damage. To maintain safety in the event
of malfunction of the Digital Controller, take appropriate safety
measures, such as installing a monitoring device on a separate
line.
Warning!

1.3 Precautions for safe use
Be sure to observe the following precautions to prevent operation failure,
malfunction, or adverse affects on the performance and functions of the
product. №t doing so may occasionally result in unexpected events. Do not
handle the Digital Controller in ways that exceed the ratings.
• The product is designed for indoor use only. Do not use or store the product
outdoors or in any of the following places.
- Places directly subject to heat radiated from heating equipment.
- Places subject to splashing liquid or oil atmosphere.
- Places subject to direct sunlight.
- Places subject to dust or corrosive gas (in particular, sulfide gas and
ammonia gas).
- Places subject to intense temperature change.
- Places subject to icing and condensation.
- Places subject to vibration and large shocks.
• Installing two or more controllers in close proximity might lead to increased
internal temperature and this might shorten the life cycle of electronic
components. It is strongly recommended to install cooling fans or other
air-conditioning devices inside the control cabinet.
• Always check the terminal names and polarity and be sure to wire properly.
Do not wire the terminals that are not used.
• To avoid inductive noise, keep the controller wiring away from power
cables that carry high voltages or large currents. Also, do not wire power
lines together with or parallel to Digital Controller wiring. Using shielded
cables and using separate conduits or ducts is recommended. Attach a
surge suppressor or noise filter to peripheral devices that generate noise
(in particular motors, transformers, solenoids, magnetic coils or other
equipment that have an inductance component). When a noise filter is used
at the power supply, first check the voltage or current, and attach the noise
filter as close as possible to the Digital Controller. Allow as much space as
possible between the Digital Controller and devices that generate powerful
high frequencies (high-frequency welders, high-frequency sewing
machines, etc.) or surge.
• A switch or circuit breaker must be provided close to device. The switch
or circuit breaker must be within easy reach of the operator, and must be
marked as a disconnecting means for the controller.

User manual - ATR444 - 9
• The device must be protected by a fuse 1A (cl. 9.6.2).
• Wipe off any dirt from the Digital Controller with a soft dry cloth. Never
use thinners, benzine, alcohol, or any cleaners that contain these or other
organic solvents. Deformation or discoloration may occur.
• The number of non-volatile memory write operations is limited. Therefore,
use EEprom write mode when frequently overwriting data, e.g.: through
communications.
• Chemicals/solvents, cleaning agents and other liquids must not be used.
• Non-respect of these instructions may reduce performances and safety of
the devices and cause danger for people and property.
For CT (Current Transformer) input:
• Warning: To reduce risk of electric shock, always open or disconnect circuit
from power-distribution system (or service) of building before installing or
servicing current transformers
• For use with Listed Energy-Monitoring Current Transformers
• The current transformers may not be installed in equipment where they
exceed 75 percent of the wiring space of any cross-sectional area within the
equipment
• Restrict installation of current transformer in an area where it would block
ventilation openings
• Restrict installation of current transformer in an area of breaker arc venting
• №t suitable for Class 2 wiring methods
• №t intended for connection to Class 2 equipment
• Secure current transformer and route conductors so that the conductors do
not directly contact live terminals or bus.
1.4 Environmental policy / WEEE
Do not dispose electric tools together with household waste material.
According to European Directive 2012/19/EU on waste electrical and electronic
equipment and its implementation in accordance with national law, electric
tools that have reached the end of their life must be collected separately and
returned to an environmentally compatible recycling facility.

5 Electrical wirings
This controller has been designed and manufactured in conformity to Low
Voltage Directive 2006/95/EC, 2014/35/EU (LVD) and EMC Directive 2004/108/
EC, 2014/30/EU (EMC). For installation in industrial environments please observe
following safety guidelines:
• Separate control line from power wires.
• Avoid proximity of remote control switches, electromagnetic contactors,
powerful engines.
• Avoid proximity of power groups, especially those with phase control.
•
It is strongly recommended to install adequate mains filter on power supply
of the machine where the controller is installed, particularly if supplied
230Vac. The controller is designed and conceived to be incorporated into
other machines, therefore CE marking on the controller does not exempt
the manufacturer of machines from safety and conformity requirements
applying to the machine itself.
• Wiring of pins 1...15, use crimped tube terminals or flexible/rigid copper wire
with diameter 0.2 and 2.5 mm² (min. AWG28, max. AWG12; Minimum temp.
rating of the cable to be connected to the field wiring terminals, 70°C). Cable
stripping lenght 7 to 8 mm. Tighten screws to tightening torque of 0,19 Nm.
• Wiring of pins 16...35, use crimped tube terminals or flexible/rigid copper
wire with diameter 0.2 and 1.5 mm² (min. AWG28, max. AWG14; Minimum
temp. rating of the cable to be connected to the field wiring terminals, 70°C).
Cable stripping lenght 6 to 7 mm. Tighten screws to tightening torque of
0,51 Nm.
• Use Copper or Copper-Clad Aluminum Conductors Only or AL-CU or CU-AL.

“DIx” on pin “+V” to enable digital input.
It is possible to put in parallel the digital inputs of different
devices joining together the 0V pins (20).
In the version ATR444-14ABC-T only DI1 and DI2 are
available
