  • Page 3: Introduction

    Its non-observance can cause a very serious risk for the exposed personnel. INTRODUCTION The JANUS TRX photoelectric barrier is a double-beam optoelectronic safety system. It belongs to the family of Type 4 electrosensitive devices for the protection of personnel exposed to risks arising from the use of hazardous machinery or plant, according to standards IEC 61496-1,2 and EN 61496-1.

  • Page 4: Principle Of Operation

    PRINCIPLE OF OPERATION Figure 1 shows the JANUS TRX way of operation : active element J TRX E/R contains emitter receiver units; the emitted infrared beam, correctly reflected by the two pre-aligned deflection mirrors of the passive element J TRX RR, is received by the receiver of the J TRX E/R.

  • Page 5: Installation

    INSTALLATION Before installing the JANUS TRX safety system, make sure that: The safety system is only used as a stopping device and not as a machine control device. The machine control can be actuated electrically. All dangerous machine movements can be interrupted immediately. In particular, the machine stopping times must be known and, if necessary, measured.

  • Page 6: Position

    (REER labels in the same side) Figure 2 MULTIPLE SYSTEMS JANUS TRX is composed of one active and one reflecting element; when more than one JANUS TRX system is used, precaution must be taken to avoid optical interference between them.

  • Page 7: Safety Distance Calculation

    SAFETY DISTANCE CALCULATION The barrier must be installed at a distance that is greater than or equal to the minimum safety distance S, so that a dangerous point can only be reached after all hazardous machine movements have stopped (Figure 3). According to European standard EN999, the minimum safety distance S must be calculated using the following formula: S = K (t...

  • Page 8: Vertical Position Of The Barrier

    Before making the electrical connections, make sure that the supply voltage complies with the one specified in the technical data sheet. Janus TRX must be supplied with 24V ±20% power supply. The external power supply must comply with the standard EN 60204-1.

  • Page 10: Distance Between Reflecting Surfaces

    DISTANCE BETWEEN REFLECTING SURFACES The presence of reflecting surfaces in proximity of the photoelectric barrier may generate spurious reflections that prevent monitoring. With reference to Figure 6, object A is not detected because surface S reflects the beam and closes the optical path between the active and passive elements.
  • Page 11 Figure 7 After installing the system, check whether any reflecting surfaces intercept the beams, first in the centre and then in the vicinity of the active unit. During these operations, the red LED on the active elements should never, for any reason, switch off.

  • Page 12: Mounting And Optical Alignment

    MOUNTING AND OPTICAL ALIGNMENT The active element J TRX E/R and the the passive element J TRX RR must be mounted the first in front of the other with the same (or less) distance showed in the technical data. Using the fastening brackets and inserts (available on request) fix the active element J TRX E/R and the passive element J TRX RR aligned and parallel.

OUTPUT STATUS Janus TRX features two static PNP outputs on the active element, the status of which depends on the condition of the protected area. The maximum load allowed is 500mA at 24VDC, which corresponds to a resistive load of 48Ω.
