EZ-SCREEN
®
AC Interface Box
WARNING . . .
Electrical
Shock Hazard
Electrical shock hazard exists when the
EZ-SCREEN AC Interface Box has power
applied to it and the box cover is open. Use
extreme caution to avoid electrical shock during
installation or servicing, or when the box cover
is open to change the switch configuration or
replace the relay board module.
Always disconnect all power from the box
and the guarded machine before making
any connections, replacing any component,
or before opening the enclosure housing of
the box.
WARNING . . .
Electrical
Hookup
Electrical hookup must be made by a
qualified electrician, and must comply with
NEC (National Electrical Code) and local
standards. Also, make no more connections
to the EZ-SCREEN AC Interface Box than are
described in this document.
Connection of other wiring or equipment to
the box could result in serious bodily injury
or death.
CAUTION . . .
Ensure Proper Monitoring
The primary safeguarding system must be
capable of external device monitoring of the
EZAC-R.. models, and employ a Normally Open
Reset contact. Thus, the EZ-SCREEN AC
Interface Box is not intended to be used with EZ-
SCREEN Type 2 (model numbers LS2..).
Electrical Installation
The hookup for a particular box is dependent on the model (see Figures 5-9). For models with
EDM, this should be configured before the initial checkout and use of the light screen. EDM
is configured via a combination of the electrical hookup and a sliding switch inside the box
(depending on model; see page 6).
All EZAC-R.. models have one 8-pin M12 Euro-style QD to connect to the EZ-SCREEN
receiver and/or emitter. QD models have one 3-pin Mini-style QD for power and ground input,
plus a Mini-style I/O connector (either 8-pin or 5-pin, depending on model) to connect to the
safety outputs and monitoring contacts (i.e., EDM). Non-QD (hard-wired) models have two holes
with 1/2" NPT threads to accommodate conduit fitting or cable gland and hard-wire cables
(two cable glands and one hole plug included with box).
EZAC-E.. models have one (8-pin or 5-pin) M12 Euro-style QD to connect to the emitter, plus
a 3-pin or 5-pin Mini-style connector for power and ground. Hard-wired emitter models have
one hole and one cable gland.
Connection to the Guarded Machine
The hook-up diagrams in Figures 5-9 show a generic connection of two safety output channels
of the models EZAC-R.. AC Interface box to machine primary control elements MPCE1 and
MPCE2. A machine primary control element is an electrically powered device, external to the
box, which stops the machinery being controlled by immediately removing electrical power
from the machine and (when necessary) by applying braking to dangerous motion.
WARNING . . .
Not for Use as a Stand-Alone Safety Module
1. DO NOT connect E-stop switches, -hand control switches, safety interlock switches, or similar
devices directly to this interface module.
2. Always connect pins 2 and 3 of the receiver/emitter M12/Euro-style QD connection to the monitoring input
of the Primary Safeguarding Device that controls it (see Figure 4).
The EZAC box does not have the circuitry required to perform a self-check. A single fault inside the unit
or in external devices (like switches or E-stop buttons) can go undetected and create an unsafe condition.
Failure to properly connect the EZAC box to a control-reliable Primary Safety Device could result in
serious injury or death.
