WARNING . . .
Use of Transient
Suppressors
If transient suppressors are used, they
MUST be installed across the coils of
the machine control elements. NEVER
install suppressors directly across the
contacts of the IM-T-..A Module! It is
possible for suppressors to fail as a
short circuit . If installed directly across
the contacts of the IM-T-..A Module, a
short-circuited suppressor will create an
unsafe condition .
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.
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.
