WARNING ...
Use of Arc
Suppressors
If arc suppressors are
used, they MUST be installed as shown
across the coils of the Machine Primary
Control Elements (MPCEs). NEVER install
suppressors directly across the output
contacts of the DUO-TOUCH Safety
Module. It is possible for suppressors to
fail as a short circuit. If installed directly
across the output contacts of the
DUO-TOUCH Safety Module, a
short-circuited suppressor will create an
unsafe condition which could result in
serious injury or death.
!
WARNING ...
Interfacing
Safety Outputs
Never wire or interface an
intermediate device (e.g., PLC, PES, PC)
that can fail in such a manner that there
is the loss of the safety stop command to
the MPCEs. To do so could result in serious
bodily injury. See page 7, Connection to the
Machine to be Controlled.
