MC3
MC3, MC4 and MC6 Series
Safety Mat Controllers
The MC Series safety mat controllers are used in conjunction
with a four-wire, normally open, safety mat where perimeter guard-
ing is required. These control reliable controllers send a stop
signal to the guarded machine when an object of sufficient weight
is detected on the active mat area.
The MC Series controllers, when combined with a four-wire
UM or UMQ series mat, provide access guarding and improved
productivity. The work area is fully visible and accessible.
The controller meets the requirement of EN 1760-1:1998,
EN 13849-1, ANSI/RIA 15.06-1999 (R2009), ANSI B11.19-2010,
OSHA 1910-217C. CSA and UL508.

Description
MC3
The MC3 DIN mount controller may be used in applications
that do not require the feature set of the MC6 controller. The MC3
single zone mat controller has removable terminal blocks and
operates only on 24 VDC.
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.
MC4
The MC4 is a NEMA 4, 12 rated single zone mat controller. This
controller may be used in applications when the diagnostic fea-
tures of the MC6 may not be required. The MC4 may be ordered
in either 24 VDC or the universal auto-selecting power supply for
100-240 VAC.
Perimeter Guarding Requirements
For perimeter guarding installations, the guarded machine or
robot controller must be wired such that any stop signal gener-
ated 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.
MC6
The MC6 is a NEMA 4, 12 controller with six individual mat
zone indicators and is designed to be backward compatible with
the MC4. Both units are dimensionally identical. This is where the
similarities stop: The MC6 has full featured diagnostics with a 24
VDC and an optional universal power supply (100-240 VAC auto-
selecting). It is a controller that can be used anywhere in the world.
