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.
The design and installation of the interlocked guard and the safety switches should comply with ANSI B11.19, ISO14119, ISO 14120,
and/or 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).
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.
Emergency Stop Push Buttons and Rope/Cable Pull Switches
The safety inputs can be interfaced with positive-opening switches to monitor an emergency-stop (E-stop) push button or rope/cable pull.
The switch must provide one or two contacts for safety which are closed when the switch is armed. Once activated, the E-stop switch
must open all its safety-rated contacts, and must require a deliberate action (such as twisting, pulling, or unlocking) to return to the
closed-contact, armed position. The switch must be a "positive-opening" (or direct-opening) type, as described by IEC 60947-5-1.
Standards ANSI NFPA 79, ANSI B11.19,, IEC/EN60204-1, and ISO 13850 specify additional emergency stop switch device require-
ments, including the following:
• Emergency-stop push buttons shall be located at each operator control station and at other operating stations where emergency
shutdown is required.
• Stop and emergency-stop push buttons shall be continuously operable and readily accessible from all control and operating stations
where located. Do not mute or bypass E-stop buttons or rope/cable pulls.
• Actuators of emergency-stop devices shall be colored red. The background immediately around the device actuator shall be colored
yellow (where possible). The actuator of a push-button-operated device shall be of the palm or mushroom-head type.
• The emergency-stop actuator shall be a self-latching type.
In addition, for Rope/Cable Pull Installations Only:
• The red wire rope should be easily visible and readily accessible along its entire length. Red markers or flags may be fixed on the
rope to increase its visibility.
• The rope or cable pull must provide constant tension and must have the capability to react to a force in any direction.
• Mounting points, including support points, must be rigid.
• The rope should be free of friction at all supports. Pulleys are recommended.
• The switch must have a self-latching function that requires a manual reset after actuation
Some applications may have additional requirements; comply with all relevant regulations. See the device manufacturer installation in-
structions for complete information (such as SSA-EB1..-.. p/n 162275, or RP-RM83F.. p/n 141245 data sheets).
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.
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.
