SC22-3 Safety Controller
Instruction Manual
Appendix A
A.7.2 SC22-3 Emergency Stop Hookup Options
The device is shown in the armed or Run state .
Single-Channel (1 terminal, 2 terminals, or PNP device):
These circuits can typically meet ISO 13849-1 Category 2
requirements, depending on the design and installation of the
switch . At a minimum, the switch must be a safety-rated device
in order to achieve Category 2 . The 1-terminal and the PNP
device can not detect a short circuit to another source of power .
Two-terminal hookup uses pulse monitoring and can detect a
short circuit to another source of power . Fault Exclusion must be
used to achieve higher level of safety circuit integrity .

Dual-Channel (2 terminals or 3 terminals): This circuit typically
can meet ISO 13849-1 Category 3 requirements, depending on
the design and installation of the switch . Dual-channel 3-terminal
hookup uses pulse monitoring and can detect a short circuit to
another source of power .Both 2- and 3-terminal hookup can
detect a short between channels when the contacts are open if
the short is present longer than 2 seconds .

A.8 Rope/Cable Pull
Rope pull (cable pull) emergency stop switches use
steel wire “rope”; they provide emergency stop
actuation continuously over a distance, such as along
a conveyor .
Rope pull emergency stop switches have many of the same
requirements as emergency stop push buttons, such as “positive
opening” (or direct-opening) operation, as described by
IEC 60947-5-1 . See Section A.7 on emergency stop push
buttons for additional applicable information.
It is recommended to use rope pull emergency stop switches
that have the capability not only to react to a pull in any
direction, but also to slack or a break of the rope . Typically, this
is accomplished by separate contacts within the switch . When
the rope is properly tensioned, both contacts of the switch are
closed . When the rope is pulled, the positive-break contacts
open . If the rope breaks or goes slack, the second set of
contacts opens . See section A .8 .2 for hookup options .
Some rope pull emergency stop switches provide a latching
function that requires a manual reset after actuation . If using a
switch that does not provide a latching function after the rope is
released, a separate latching circuit is required, which can be
provided by the SC22-3 Safety Controller .
