Description
The Safety Mat controllers
SMC-1M6, MC3 and MC4 are
used in conjunction with fourwire, normally open, safety mats
where perimeter guarding is
required. Their control reliable,
surface-mount design sends a
stop signal to the guarded machine whenever an object with
sufficient weight is detected on
the active mat surface. Also when
the controller detects any of the
mat wires are missing, broken, or
mis-connected a stop signal is
generated.
When combined with a fourwire safety mat these controllers
improve productivity while
providing access guarding. Full
visibility of and accessibility to
the work area is always maintained.
STI safety mat controllers meet
the requirements of ANSI B11.191990 for safety mats controllers
and OSHA 1910.212 for general
machine guarding.

SafetyMat Controllers
■
Models Available
SMC-1M6
This DIN-rail mount controller
provides inputs and monitoring
for six separate mat zones with a
maximum combined area of 300
square feet. These six zones share
a common safety output. Removable terminal blocks simplify
installation when the controller is
mounted on the DIN rail. Unit
operates from 24 VDC only.
Additional Guarding Requirements
A safety mat system is often only one part of a machine guarding
solution. If the safety mat does not protect all access to the point of
operation, additional guarding must be used. Safety mat systems
should only be used to detect the presence, not the absence, of a force.
Perimeter Guarding Requirements
For perimeter guarding installations, the guarded machine or robot
controller must be wired such that any stop signal generated by the
safety mat system will cause an immediate stop of the hazardous
motion. The machine or robot must only be restarted by the actuation of
a manual reset switch. This reset switch must be located outside the
area of hazardous motion and positioned such that the hazardous area
can be observed by the switch operator. The purpose of this arrangement is to prevent a machine or robot from automatically restarting once
the sensing weight is no longer detected by the safety mat sensing area.

SafetyMat Controllers
Safety Standards and
Precautions
An STI safety mat controller is a
general purpose, safety mat
control device and is not designed
to guard any specific type, model
or brand of machine. All safetyrelated functions of the guarded
machine controls including
pneumatic, electric, logic or
hydraulic controls must be control
reliable.
An STI safety mat controller,
when combined with a four-wire
safety mat meets ANSI/RIA
R15.06-1999, ANSI B11.19-1990
and the following applicable
■
OSHA standards. When used with
mechanical power presses, OSHA
standard 1910.217(c) applies. For
other applications the requirements of section 1910.212 apply.
Only use a safety mat controller
and four-wire safety mat system
on machinery that stops consistently and immediately anywhere
in its cycle or stroke. Never use a
safety mat controller and four-wire
safety mat system on a fullrevolution clutched press or
machine. Access to the point of
operation or hazardous machine
area not protected by the safety
mat controller and four-wire safety
mat system must be guarded by
fencing, barriers or other appropriate methods.
The purchaser, installer and
employer are responsible for
meeting all local state and federal
government laws, rules, codes or
regulations relating to the proper
use, installation, operation and
maintenance of this control and
the guarded machine. See Installation and Operation Manual for
additional information.
All application examples described are for illustration purposes only. Actual installations
will differ from those indicated.
Ordering Information
