This document is also applicable to pressure sensing controls for appliances within the scope of IEC 60335-1.
This document applies to
- the inherent safety of pressure sensing controls, and
- functional safety of pressure sensing controls and safety related systems,
- pressure sensing controls where the performance (for example the effect of EMC phenomena) of the product can impair the overall safety and performance of the controlled system,
- the operating values, operating times, and operating sequences where such are associated with equipment safety.
This document specifies the requirements for construction, operation and testing of automatic electrical controls used in, on, or in association with an equipment.
This document does not
• apply to pressure sensing controls intended exclusively for industrial process applications unless explicitly mentioned in the relevant part 2 or the equipment standard. However, this document can be applied to evaluate automatic electrical controls intended specifically for industrial applications in cases where no relevant safety standard exists;
• take into account the response value of an automatic action of a pressure sensing control, if such a response value is dependent upon the method of mounting the control in the equipment. Where a response value is of significant purpose for the protection of the user, or surroundings, the value defined in the appropriate equipment standard or as determined by the manufacturer will apply;
• address the integrity of the output signal to the network devices, such as interoperability with other devices unless it has been evaluated as part of the control system.
This document contains requirements for electrical features of pressure sensing controls and requirements for mechanical featu
