NOTE:
See pages 33-34
for explanation
of single- and
dual-channel stop
circuits
* Installation of transient suppressors across the coils of FSD1
and FSD2 is recommended. NOTE: Do not exceed OSSD
maximum load capacitance specification.
1) See Section 3.5 for more
information on Reset input and
hookup.
2) See Section 3.7.3 for information
on EDM input and hookup.
3) TEST input must be jumpered if
not used. Typically a Normally
Open switch held closed. See
Section x.x for information on
TEST input and hookup.

WARNING . . .
Proper Wiring
The generalized wiring
configurations shown are provided only
to illustrate the importance of proper
installation .
The proper wiring of the EZ-SCREEN
System to any particular machine is
solely the responsibility of the
installer and end user.

CAUTION. . .
Shock Hazard
Always disconnect all
power from the EZ-SCREEN System
and the guarded machine before
making any connections or replacing
any component. Use extreme caution
to avoid electrical shock at all times.
Serious bodily injury or death could
result.
WARNING . . .
OSSD Interfacing
To ensure proper
operation, the EZ-SCREEN OSSD
output parameters and machine input
parameters must be considered when
interfacing the EZ-SCREEN solid-state
OSSD outputs to machine inputs.
Machine Control circuitry must be
designed so that the maximum load
resistance value is not exceeded and
that the maximum specified OSSD
OFF-state voltage does not result in an
ON condition.
Failure to properly interface the
OSSD outputs to the guarded
machine could result in serious
bodily injury or death.
