KUHNKE Automation Reliability, Safety 3 Reliability, Safety 3.1 Intended Use The thermo-controller is designed as operating equipment in industrial envi- ronments and for connection to non-public mains. All other applications need to be discussed with the factory first. The manu- facturer shall neither be liable for any other than the intended use of our products nor for any ensuing damages. The risk shall be borne by the opera- tor alone. The use as intended includes that you read and apply all informa- tion and instructions contained in this manual.
3.2 Target Group This instruction manual contains all information necessary for the use of the described product (control device, control terminal, software, etc.) according to instructions. It is written for design, project planning, servicing and com- missioning experts. For proper understanding and error-free application of technical descriptions, instructions for use and particularly of notes of danger and warning, extensive knowledge of automation technology is compulsory. 3.3 Reliability Reliability of Kuhnke products is brought to the highest possible standards by extensive and cost-effective means in their design and manufacture. These include:
• selecting high-quality components, • quality agreements with our suppliers, • actions to avoid static charges when handling MOS circuits, • worst case planning and design of all circuits, • visual inspections at various stages of fabrication, • computer-aided tests of all assemblies and their interaction in the circuit, • statistical assessment of the quality of fabrication and of all returned goods for the immediate taking of appropriate corrective actions. 3.4 Symbols Despite the actions described in section 2.3, the occurrence of faults or er- rors in electronic control units - even if most highly improbable - must be taken into consideration.
Please pay particular attention to the additional notices which we have marked by symbols throughout this instruction manual. While some of these notices make you aware of possible dangers, others are intended as a means of orientation. They are described further down below in descending order of importance.
