User Manual

1. Safety Module ES-FA-9AA is configured for manual reset. See data sheet p/n 60606 for complete information. Other Safety Mod-
ules can be used. Call Banner Engineering with all questions.
2. After the guard has been closed, the Safety Module has been reset, and the machine control has started the motor, the Request to
Enter button can be pushed to interrupt the cycle.
3. The machine control and the SSM Safe-Speed Monitoring Module enable the Unlock button and illuminate the OK to Open light.
4. The signal from the Unlock button energizes the solenoid locking mechanism of the locking style safety switch, allowing the guard
to be opened. It is recommended to locate the Unlock button near the associated guard. The solenoid contact prevents the reset of
the ES-FA-9AA Safety Module until the guard is locked.
5. Arc Suppressor, see Warning.
6. See the External Device Monitoring section and the warning, Interfacing MPCEs.
7. Not all feedback or monitoring functions of the machine interface are shown.
WARNING: WARNING . . . Interfacing MPCEs. NEVER wire any intermediate device(s) (e.g., PLC,
PES, PC), between the Safety Module outputs and the Machine Primary Control Elements (MPCE1
to MPCE3) 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 Interface Module
terminals Y1 and Y2.
WARNING: WARNING . . . Wiring of Arc Suppressors. If arc suppressors are used, they MUST be
installed as shown across the coils of the Machine Primary Control Elements (MPCE1 to MPCE2). NEV-
ER install suppressors directly across the output contacts of the Safety Module. It is possible for suppres-
sors to fail as a short circuit. If installed directly across the output contacts of the Interface Module, a short-
circuited suppressor will create an unsafe condition which could result in serious injury or death.
CAUTION: CAUTION . . . Shock Hazard. Always disconnect power from the Safety Module and all
power from the machine being controlled before making any wire connections. Electrical installation
and wiring must be made by qualified personnel and must comply with the NEC (National Electrical Code),
EN60204-1 and -2, and all applicable local standards and codes.
External Device Monitoring
To satisfy the requirements of Control Reliability (OSHA and ANSI), Category 3 and 4 of ISO 13849-1 (EN 954-1), the Machine Primary
Control Elements (MPCEs) must each offer a normally closed, forced-guided (mechanically linked) monitor contact. Connect one normal-
ly closed monitor contact from each Machine Primary Control Element as shown in the appropriate hookup drawing.
In operation, if one of the switching contacts of either MPCE fails in the energized condition, the associated monitor contact will remain
open. Therefore, it will not be possible to reset the Primary Safety Device . If no MPCE-monitor contacts are monitored, it is the user's
responsibility to ensure that any single failure will not result in a hazardous condition and will prevent a successive machine cycle.
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 output contact voltage 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.
