WARNING . . .
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 . . .
NEVER wire an intermediate device(s) (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 the loss of the safety stop command, OR
in such a manner that 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 S31 and S32.
