** The Safety Module can not be reset until the delay output
times out and switches, or until the Cancel Delay Input is
exercised. Attempting to reset the module (Manual Reset
mode) or re-arming the E-stop button (Auto Reset mode)
before the time-out occurs will result in a lockout (see
page 14 for instructions for clearing lockouts).
*** Arc suppressors (see WARNING).

Wiring of Arc Suppressors
If arc suppressors are
used, they MUST be installed as
shown across the actuator coil of
the Master Stop Control elements
(MSC1 to MSC4). NEVER install
suppressors directly across the
output contacts of the E-Stop
Safety Module. It is possible for
suppressors to fail as a short circuit.
If installed directly across the output
contacts of the Safety Module, a
short-circuited suppressor will
create an unsafe condition which
could result in serious injury or
death.
WARNING . . .
!
Interfacing MSCs
NEVER wire an
intermediate device (e.g., PLC, PES,
PC) between E-Stop Safety Module
outputs and the Master Stop Control
Element it switches, in such a manner
that:
• In the event of a failure there is a loss
of the safety stop command, or,
• The safety function can be
suspended, overridden, or defeated,
unless accomplished with the same
or greater degree of safety.
Whenever forced-guided, mechanically
linked relays are added as intermediate
switching devices, a normally closed
forced-guided monitor contact from
each relay must be added to the
series feedback loop between Safety
Module terminals X3 and X4 or X5
and X6.
