Rope Pull Switches RPS…

1. Correct use
According to EN 60947-5-5 and EN ISO 13850, rope pull switches can be used to initiate an emergency stop function in
order to avoid existing or impending hazard situations.
The following applicable standards must be taken into account for this purpose:
Ì
Regulations on installation and operation:
EN ISO 13849-1
Ì
Risk assessment on the machine:
EN ISO 12100
Ì
Functional requirements and design principles for the emergency stop function:
EN ISO 13850
The purpose of these regulations is to prevent any danger for persons or damage to machines.
The safety rope pull switches of the series RPS have been designed and tested in accordance with the standards EN 60947-5-5
and EN ISO 13850. They must be used only in control circuits.
Safety rope pull switches are used on the accessible sides of conveyor systems or machines. In contrast to emergency
stop switches (e.g. mushroom-head pushbuttons) located at certain intervals that allow the emergency stop signal to be
generated only at the devices themselves, rope pull switches allow signal generation at any point along the rope length.
The safety rope pull switches of the type RPS are intended for use only in closed rooms.
2. Layout
The safety rope pull switches of the type RPS consist of a polyamide housing, those of the type RPS-M of a die-cast aluminum
housing. They achieve the specified degree of protection IP67 if the cover is properly closed and if a cable gland is used
that offers at least equivalent protection. The RPS has three cable entries M20x1.5.
The switches comply with the international requirements according to EN 60947-5-5 and EN ISO 13850, i.e. after actuation
or a rope tear, the emergency stop switch latches automatically and the switch can then be reset to its initial position only
by means of the resetting device on the switch.
Depending on the switch version, it is possible to achieve a rope length of up to 75 m. It must be taken into account here
that the friction in the overall system can become so high due to the rope guides that this makes it difficult or impossible
to reset the system (see “Mounting” section).
This can be avoided by choosing different system components.
The user is responsible for ensuring that the system functions properly.
