Banner ES-FA-6G Safety Module - Manual (Page 4)

• Mounting points, including support points, must be rigid.
• The rope should be free of friction at all supports. Pulleys are recommended.
WARNING: Emergency Stop Functions
Do not mute or bypass any Emergency Stop device. ANSI B11.19, ANSI NFPA79 and IEC/EN
60204-1 require that the Emergency Stop function remain active at all times.
Some applications may have additional requirements; comply with all relevant regulations. See the device manufacturer installation in-
structions for complete information (such as SSA-EB..-.. p/n 111880, or RP-RM83F.. p/n 141245 data sheets).
Interlocked Guards (Gates)
The safety inputs can be interfaced with positive-opening safety switches to monitor the position of an interlock guard or gate. Each
switch must provide electrically isolated contacts: at minimum, one normally closed (N.C.) contact from each individually mounted switch.
The contacts must be of "positive-opening" (direct-opening) design, as described by IEC60947- 5-1, with one or more normally closed
contacts rated for safety. 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.
In higher levels of safety performance, the design of a dual-channel coded magnetic switch typically uses complementary switching, in
which one channel is open and one channel is closed at all times. The inputs of the Safety Module do not support complementary
switching, and thus should not be used with coded magnetic safety switches.
The design and installation of the interlocked guard and the safety switches should comply with ANSI B11.19, ISO14119, and other
applicable standards. See the device manufacturer installation instructions for complete information (such as GM-FA-10J p/n 60998, SI-
LS83/-LS100 p/n 59622, or SI-HG63 p/n 129465 datasheets).
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 (for example, exhaust fans), adequate enclo-
sure exterior surface area, and spacing between modules and other sources of heat.
Electrical Installation
WARNING: Shock Hazard and Hazardous Energy
Always disconnect power from the safety system (for example, device, module, interfacing, etc.)
and the machine being controlled before making any connections or replacing any component.
Electrical installation and wiring must be made by Qualified Personnel and must comply with the relevant
electrical standards and wiring codes, such as the NEC (National Electrical Code), ANSI NFPA79, or IEC
60204-1, and all applicable local standards and codes.
Lockout/tagout procedures may be required. Refer to OSHA 29CFR1910.147, ANSI Z244-1, ISO
14118, or the appropriate standard for controlling hazardous energy.
It is not possible to give exact wiring instructions for a Safety Module that interfaces to a multitude of machine control configurations. The
following guidelines are general in nature.
The Safety Module has no delay function. Its output relay contacts open within 25 milliseconds after a safety input opens. This classifies
the Safety Module as a functional stop "Category 0" control, as defined by ANSI NFPA 79 and IEC/EN 60204-1.
The Safety Module is powered by either a 12-24V dc supply at 4W or an ac supply (115V ac, model ES-UA-5A, or 230V ac, model ES-
VA-5A) at 7VA. The safety inputs can be connected to:
• A +24V dc source that is switched by a hard/relay contact in single-channel hookup configuration, or
• Hard/relay contacts in a dual-channel hookup configuration using terminals S11-S12 and S21-S22.
