An Emergency Stop Device, including,
but not limited to buttons, rope pulls and
cable pulls, is not generally considered
a safeguard; and does not alone fulfill
U.S. or International requirements for
safeguarding hazards associated with
machinery.
The definition of safeguarding is the
"protective measure using safeguards [guards
or protective devices] to protect persons from
the hazards which cannot reasonably be
eliminated..." (ISO12100-1, 3.29 and 3.30).
A safeguard limits or eliminates an individual's
exposure to a hazard (examples include
interlocking devices, safety mats, safety light
screens). An emergency stop is considered
to be a complementary protective measure,
which is neither an inherently safe design
measure, nor safeguarding, but may
be required as part of the safety related
control system and risk reduction strategy
(ISO12100-2, 4.5.1 and 4.5.2).
The user must refer to the relevant
standard(s) to determine the safeguarding
requirements for their particular situation.

This symbol for a positive-opening safety contact (IEC 60947-5-1) is used in the switching diagram to identify the point in actuator travel where
the normally-closed safety contact is fully open.

Models RP-LS42F-75L.. are rope pull emergency stop switches in compact, limit switch-
style housings made of high-impact thermoplast. When used with steel wire rope, they
can provide emergency stop actuation along conveyors and similar machinery. Red
PVC-covered 3 mm diameter wire rope is recommended (see page 10).
The switches have redundant contacts; terminals 21/22 and 41/42 are positive opening
when there is a cable-pull or cable-brake situation. When used separately, these contacts
provide inputs to a dual-channel safety module (see Figure 6). Terminals 21/22 and
41/42 can also be used individually to provide single-channel switching or as a single-
channel input to a safety module. Terminals 13/14 and 33/34 are for monitoring purposes
only (closed in a cable-brake/-pull situation).
When the rope is properly tensioned (240N), the red arrows are centered on the hash
mark on the tension indicator window, the contacts at terminals 21/22 and 41/42 are
closed, and the contacts at terminals 13/14 and 33/34 are opened (see Figures 1, 2
and 4).
These rope pull emergency stop switches are not generally considered safeguarding
devices, in that they do not prevent or reduce exposure of individuals to a hazard. They
provide the same function as other types of emergency stop switches.
All models feature “latching” operation. When the rope is pulled, the switch contacts
21/22 and 41/42 open and remain open until the built-in reset button is manually reset
(see Figure 1).
