This Technical Specification is a collection of interpretations related to the EN 115 series. This document collects interpretations to EN 115- 1:2008+ A1:2010. Interpretations to other standards of the EN 115 series will be added when they are available.
Interpretations aim to improve the understanding of the clause(s) they are referring to and by that facilitating common understanding between manufacturers, lift installers, notified bodies, inspection bodies and national authorities.
Interpretations do not have the same status as the European Standards to which they are related.However, the application of interpretations should give to the interested parties confidence that the relevant European Standard has not been wrongly applied.
The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Operation in “two direction mode” for escalators with automatic start is permitted under the following conditions:
a) On escalators which can start automatically in either direction (“two direction mode”) by the entering of a user, the “two direction mode” and the momentary capable direction of travel shall be clearly visible to the user and marked distinctly on the escalator (see 7.2.2 plus “two direction mode” sign). They shall start in the direction determined by the user entering first. When the escalator is started by a user from either direction, the indicator opposite from the initiated starting side shall automatically indicate “no entry” (see 7.2.2).
b) Measures for control and/ or monitoring function shall prevent:
– failures of the control elements actuating the automatic start at the entries (e.g. no or partly no detection of users);
– a restart of the step band when a user has entered the area between the control element and the comb intersection line and the step band is stopped.
c) Control and monitoring function shall be regarded as electric safety devices and shall be applied as safety switches (5.12.1.2.2), fail safe circuits (5.12.12.3) or SIL 1 according to PESSRAE (5.12.1.2.6).AS 1735.5.4 pdf free download.
