    Chapter 1 Overview Multi-position Switches Most safety relays are configured by adjusting multi-position switches to set their functionality. The switches are on the front face of the relay so you can see the set position during, and after, configuration. During the configuration process, status indicators on the front face of the relay confirm the switch settings.

    Chapter 2 Installation Spacing Safety relays can be mounted directly next to other safety relays. When the EtherNet/IP module is used, the safety relay must be mounted within 10 mm (0.4 in.) of its neighboring module to maintain effective communication. Maintain a space of 50.8 mm (2 in.) above, below, and in front of the relay for adequate ventilation.
  • Page 15: Prevent Excessive Heat

    Installation Chapter 2 This equipment is supplied as open-type equipment. The relays must be mounted within an enclosure that is suitably designed for those specific environmental conditions that are present and appropriately designed to help prevent personal injury as a result of accessibility to live parts. The enclosure must have suitable flame-retardant properties to help prevent or minimize the spread of flame, in compliance with a flame spread rating of 5VA, V2, V1, V0 (or equivalent) if non-metallic.

    Chapter 3 Power, Ground, and Wire Devices with OSSD Output Devices, such as the GuardShield™ safety light curtains, SafeZone™ laser scanners, SensaGuard™ interlock switch, TLS-Z and 440G-LZ guard locking switches, and Bulletin 442G Multifunction Access Box (MAB) have current-sourcing PNP semiconductor outputs (OSSD), which send their own pulse-tested safety signals through their outputs.
  • Page 23: Safety Mats

    A status indicator must inform you that the OSSD device is faulted. Safety Mats Guardmaster (and similar) safety mats can be connected to safety relays. These mats use parallel metal-plate technology. Stepping on the mat shorts the top metal plate to the bottom metal plate. With the proper connections, safety relays detect the presence of an object on the mat and turn off their outputs.
  • Page 24: Safedge Safety Edges

    Capacitance Effect on page 71 for further information. TIP Older Allen-Bradley Guardmaster MSR relays could be tickled by tapping on the safety mat, which generated fast cycles. This activity caused the relay to fault because the fast cycles violated the recovery time specification. GSR relays have a 20 ms recovery time, so this fault is not likely to occur.

  • Page 26: Electromechanical Outputs

    Chapter 3 Power, Ground, and Wire Electromechanical Outputs Internally, the CI, DI, EM, EMD, and SI safety relays have two positive-guided relays that are connected in series to form the safety outputs. One side of the contact must be connected to a voltage supply (see Specifications on page 89 for appropriate ratings).
  • Page 27: Surge Suppressors

    Power, Ground, and Wire Chapter 3 Surge Suppressors Because of the potentially high current surges that occur when switching inductive load devices, such as motor starters and solenoids, the use of surge suppression to help protect and extend the operating life of the relays is required.

The CI and SI safety relays only have SWS outputs (terminal L11).
  • Page 29: Auxiliary Output

    Power, Ground, and Wire Chapter 3 Auxiliary Output Each safety relay has an auxiliary output. The auxiliary output is not a safety rated output; it is a low current output that is designed to indicate that the safety output status is OFF. The auxiliary output is in the opposite state of the safety outputs.
