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. Not 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.

•  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.

Environmental policy / WEEE

Do not dispose electric tools together with household waste material.

According to European Directive 2002/96EC 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.
