Amendment 1 - Low-voltage switchgear and controlgear - Part 5-2: Control circuit devices and switching elements - Proximity switches

Gives manual methods for calculating cyclic rating factors for cables whose internal thermal capacitance cannot be neglected; in general this applies to cables for voltages greater than 18/30 (36) kV. It also gives a method for calculating the emergency rating for cables of any voltage.

Amendement 1 - Appareillage à basse tension - Partie 5-2: Appareils et éléments de commutation pour circuits de commande - Détecteurs de proximité

Fournit des méthodes manuelles de calcul des facteurs de capacité de transport en régime cyclique pour des câbles dont la capacité thermique interne ne peut pas être négligée, il s'agit généralement de câbles de tensions supérieures à 18/30 (36) kV. Donne également une méthode de calcul des capacités de transport en régime de secours pour des câbles de tout niveau de tension.

Proximity switches may have integral connecting leads; in this case the outer sheath of the

+0,1
connecting leads should be 2 m long unless otherwise agreed between manufacturer and

customer. Information provided by the manufacturer may constitute such an agreement.

NOTE National US Electrical Code states that:

1) the free length of a field wiring lead is not less than 152 mm long or 100 mm when intended for installation in
an outlet box;
2) a lead that is intended to be spliced in the field to a circuit conductor is not smaller than 0,2 mm (24 AWG)
and the insulation, when rubber or thermoplastic, is not less than 0,8 mm thick.

For proximity switches with four or eight terminals d.c. having special functions, terminals 2 or 4 may be used for
functions other than outputs. In this case, the manufacturer shall give a clear indication of the wire colour and
functionality.
d
For proximity switches with four terminals d.c., terminals 2 or 4 may be used for output combinations other than
those shown in this table. In this case, the manufacturer shall give a clear indication of the function of each
terminal.

Add a reference to new Footnote b in the cell on the line "Overall performance" and column
"Acceptance criterion B" as follows:
b
... one half cycle of supply frequency for a.c. devices
Add the following new Footnote b:
b
For a.c. devices with power consumption of more than 750 mW, the recovery time of the switching element may
be longer than one half cycle but shall be less than the specified maximum startup-time t (time delay before
v
ability) according to 7.2.1.7. The maximum recovery time shall be stated by the manufacturer in his literature.
