  • Page 18: Multiple Systems

    MULTIPLE SYSTEMS When several JANUS systems are used, these must not interfere optically with each other. Position the elements so that the beam emitted by the Emitter of a system is received only by the respective Receiver. Figure 21 provides various examples of correct positioning of two photo-electric systems.
  • Page 19 JANUS JANUS Long Range SENSITIVE AREA EMITTER RECEIVER Figure 23 After installation, check for any reflective surfaces, intercepting the beams first of all at the center and those close to the Emitter and Receiver. During this procedure, the red led on the Receiver must never switch off.
