Banner GM-FA-10J Original Instructions Manual page 4

(see OSHA 29CFR1910.217 Table O-10, ANSI B11.19, ISO 13857, ISO14120/EN953 or the appropriate standard). The guard must be
strong enough to contain hazards within the guarded area, which may be ejected, dropped or emitted by the machine.
The safety interlocking switches, actuators, sensors, and magnets must be designed and installed so that they cannot be easily defeated.
They must be mounted securely, so that their physical position cannot shift, using reliable fasteners that require a tool to remove them.
Mounting slots in the housings are for initial adjustment only; final mounting holes must be used for permanent location.
WARNING: Perimeter Guarding Applications
If the application could result in a pass-through hazard (for example, perimeter guarding), either the safe-
guarding device or the guarded machine's MSCs/MPCEs must cause a Latched response following a Stop
command (for example, interruption of the sensing field of a light curtain, or opening of an interlocked gate/
guard). The reset of this Latched condition may only be achieved by actuating a reset switch that is sepa-
rate from the normal means of machine cycle initiation. The switch must be positioned as described in this
document.
Lockout/Tagout procedures per ANSI Z244.1 may be required, or additional safeguarding, as described by
ANSI B11 safety requirements or other appropriate standards, must be used if a passthrough hazard can-
not be eliminated or reduced to an acceptable level of risk. Failure to observe this warning could result
in serious bodily injury or death.
Coded Magnetic Safety Switches
Similar to positive-opening safety switches, coded magnetic switches used with the Safety Module must provide one normally closed
contact and one normally open contact (typically a four-wire switch). The sensor and its magnet must be mounted a minimum distance of
15 mm (0.6 inches) from any magnetized or ferrous materials for proper operation. If either the sensor or magnet is mounted on a materi-
al that can be magnetized (a ferrous metal, such as iron), the switching distance will be affected. Although the sensor and magnet are
coded to minimize the possibility of false actuation, they should not be used within known fields of high-level electromagnetic radiation.
Depending on the model of sensor and magnet used, the installation must be designed to provide the correct direction of approach. The
speed of approach must be fast enough to meet the simultaneity-monitoring period of 1.0 second, approximately equal to or greater than
0.1 m (4 inches) per second. If the simultaneity requirement is not met, the Safety Module can not be reset and will not close its safety
output contacts.
Positive-Opening Interlocking Switches
Safety interlock switches used with the Safety Module must satisfy several requirements. Each switch must provide electrically isolated
contacts: at minimum, one normally closed (N.C.) contact or normally conducting source and one normally open (N.O.) contact or normal-
ly OFF source to interface with the Module.
The contacts must be of "positive-opening" design, with one or more normally closed contacts rated for safety. Positive-opening operation
causes the switch to be forced open, without the use of springs, when the switch actuator is disengaged or moved from its home position
(see the Banner Catalog for examples). In addition, the switches must be mounted in a "positive mode," to move/disengage the actuator
from its home position and open the normally closed contact, when the guard opens.
Switch Hookups, Typical Applications
Requirements vary widely for the level of control reliability or safety category (per ISO 13849) in the application of interlocked guards.
Although Banner Engineering always recommends the highest level of safety in any application, it is the responsibility of the user to
safely install, operate, and maintain each safety system and comply with all relevant laws and regulations. The applications shown in
Figure 2. Wiring to two 4-wire coded magnetic safety switches
on page 7 meet or exceed the requirements for control reliability and Safety Category 3 or 4, per ISO 13849
sourcing PNP devices
(EN954-1).
Mechanical Installation
The Safety Module must be installed inside an enclosure.
It is not designed for exposed wiring. It is the user's responsibility to house the Safety Module in an enclosure with NEMA 3 (IEC IP54)
rating, or better. The Safety Module mounts directly to standard 35 mm DIN rail.
Heat Dissipation Considerations. For reliable operation, ensure that the operating specifications are not exceeded. The enclosure must
provide adequate heat dissipation, so that the air closely surrounding the Module does not exceed the maximum operating temperature
stated in the Specifications. Methods to reduce heat build-up include venting, forced airflow (e.g., exhaust fans), adequate enclosure
exterior surface area, and spacing between modules and other sources of heat.
