This European Standard is not applicable for generating sets which are manufactured before the date of its publication as a national EN standard. It applies to generating sets for land and marine use, excluding generating sets used on board of seagoing vessels and mobile offshore units as well as on aircraft or to propel road vehicles and locomotives. The special requirements needed to cover operation in potentially explosive atmospheres are not covered in this standard. The hazards relevant to RIC engine driven generating sets are identified in Annex A. 2 Normative References The following referenced documents are indispensable for the application of this document.

6.2.2 Verification Compliance with the requirements shall be verified by inspection and testing of the starting systems. 6.3 Stopping 6.3.1 Requirements 6.3.1.1 Normal stopping All generating sets shall have a normal stopping device which can be manually or automatically actuated. Stopping controls shall remain in the stop position when operated. This shall operate by a device ensuring the cutting off of the fuel or the ignition (for spark ignition engines) supply. This device may include an air supply cut-off. 6.3.1.2 Stopping in case of failure Generating sets except low power generating sets shall be provided with an automatically actuated stopping device in case of failure.
This device shall monitor one or more signals of the generating set and if these signals are out of the allowable range it triggers the automatic stop. The main signals that might be used to actuate automatic stopping are e.g. a) for the RIC engine: 1) overspeed (see ISO 3046-6); 2) low lubricating oil pressure; SIST EN 12601:2011

6.5.1 Design, safety and mechanical strength 6.5.1.1 Requirement Control devices for the RIC engine of the generating set shall meet the following requirements:  hand controls shall be designed to withstand 1,2 times the maximum actuating forces given in
Table 1 of EN 1679-1:1998; SIST EN 12601:2011

b) the test shall be conducted in well-ventilated place not directly exposed to sunshine; c) if the test is conducted at an ambient temperature outside of the nominal (20 ± 3) oC the reported temperatures shall be corrected by the following formula: 1) corrected temperature (°C) = observed temperature (°C) – ambient temperature (°C) + 20°C. 6.5.2 Identification 6.5.2.1 Requirements The control devices of RIC engines shall comply with the requirements of Clause 6, Subclause “Identification” of EN 1679-1:1998 that shall apply. The control devices on electrical equipment shall comply with the requirements of EN 60204-1:2006, 10.1 and 10.2 with the exception as given in Annex B, 10. 6.5.2.2 Verification Compliance with the requirements shall be verified by inspection. 6.5.3 Accessibility 6.5.3.1 Requirements The requirements of EN 1679-1:1998, 6.4.3 shall apply. 6.5.3.2 Verification Compliance with the requirements shall be verified by inspection and measurement.
Fixing systems of fixed guards shall remain attached to the guards or to the generating set when the guards are removed. This requirement is limited to fixed guards that need to be removed during normal maintenance operations as described in instructions of use. For fixed installed generating sets the need of guarding shall be agreed between generating set manufacturer and installer considering that the persons shall be protected during operating and routine servicing. Because it is not possible to envisage the layout of fixed installation, the overall requirements for this situation are not dealt with in this standard. Therefore, for fixed installations, the need for additional guarding to protect persons during operation and routine servicing shall be established after discussion between the generating set manufacturer, user and installer. NOTE The provider of additional guarding for fixed installations that is outside the scope of this standard is responsible for ensuring its suitability. 6.8.1.2 Verification Compliance with the requirements shall be verified by inspection. SIST EN 12601:2011

c) The engine exhaust, with very important burn hazards during the operating, but also during cooling period following a generating sets stopping, shall be equipped with a guard to limit the most severe burn risks by direct contact. Any exhaust surface less than 10 cm2 or out of reach of operator does not need to be equipped with a protection. Engine exhaust components and their guards shall not have surface temperatures higher than 94 °C for non metallic surfaces materials or 80 °C for metallic surfaces. When a guard does not permit to reduce the temperature below the limits threshold, a warning marking shall be fixed on or near this guard to warn the generating sets user of the presence of a burn danger.
d) An enclosure with access doors for maintenance or control operations shall not be considered as protection against contact with an engine exhaust. SIST EN 12601:2011

2) For distances less than 100 mm between the identified hot area and the nearest control, cone B as shown in Figure 2 shall be used;
3) For cone A with the axis of the cone anywhere 0o and 180o to the horizontal and with the point of the cone in a downward to horizontal direction, move the cone towards the hot surface. The cone shall not be moved in an upwards direction. When moving the cone, determine if contact is made with the hot surface area(s) with the cone tip or conical surface of the cone;
4) Cone B shall be moved in any direction. b) For maintenance operations, the hot surfaces to be considered are those more than 10 cm2 located at less than 300 mm of a maintenance or control point and/or of access path for operators. c) The generating set shall be operated at its rated power until the surface temperatures stabilize.
d) The test shall be conducted in well-ventilated place not directly exposed to sunshine. e) If the test is conducted at an ambient temperature outside of the nominal (20 ± 3) oC the reported temperatures shall be corrected by the following formula: 1) corrected temperature (°C) = observed temperature (°C) – ambient temperature (°C) + 20°C Dimensions in millimetres
