GM-FA-10J Gate Monitoring Safety Module
WARNING:
Interfacing MPCEs.
NEVER wire an intermediate device(s) (e.g., PLC, PES, PC), between the Safety Module outputs and the
machine primary control element (MPCE) 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 dereated, 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 Y1 and Y2.
WARNING: Wiring of Arc Suppres-
sors
If arc suppressors are used, they
MUST be installed as shown across
the actuator coil of the stop control el-
ements (MSCs or MPCEs). NEVER
install suppressors directly across
the output contacts of the Safety
Device or Module. It is possible for
suppressors to fail as a short circuit. If
installed directly across the output
contacts, a short-circuited suppres-
sor will create an unsafe condition
which could result in serious injury
or death.
Overvoltage Category II and III Installations (EN 50178 and IEC 60664-1)
The Safety Module is rated for Overvoltage Category III when voltages of 1V to 150V ac/dc are applied to the output relay contacts. It is
rated for Overvoltage Category II when voltages of 151V to 250V ac/dc are applied to the output relay contacts and no additional precau-
tions are taken to attenuate possible overvoltage situations in the supply voltage. The Module can be used in an Overvoltage Category III
environment (with voltages of 151V to 250V ac/dc) if care is taken either to reduce the level of electrical disturbances seen by the Module
to Overvoltage Category II levels by installing surge suppressor devices (e.g., arc suppressors), or to install extra external insulation in
order to isolate both the Safety Module and the user from the higher voltage levels of a Category III environment.
For Overvoltage Category III installations with applied voltages from 151V to 250V ac/dc applied to the output contact(s): the
Safety Module may be used under the conditions of a higher overvoltage category where appropriate overvoltage reduction is provided.
Appropriate methods include:
• An overvoltage protective device
• A transformer with isolated windings
• A distribution system with multiple branch circuits (capable of diverting energy of surges)
• A capacitance capable of absorbing energy of surges
