  • Page 3: Introduction

     This symbol stands by a very important warning concerning the safety of persons. Its non-observance can cause a very serious risk for the exposed personnel. INTRODUCTION The J TRX safety light curtain is a multi-beam opto-electronic safety system of the Type 4 category of electro-sensitive devices in accordance with IEC61496-1,2 EN61496-1, for the protection of persons exposed to dangerous machines or plants.

  • Page 4: Principle Of Operation

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

  • Page 6: 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 7: Position

    To reach the perfect JANUS TRX installation, position both the units as showed in Figure 4 (REER labels in the same side) Figure 4 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 8: 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 9: Vertical Position Of The Barrier

    VERTICAL POSITION OF THE BARRIER point of danger  These models are suitable for the protection of the entire body and must not be used to protect safety arms or legs. barrier The minimum safety distance S is calculated according to the following formula: S = 1600 (t ) + 850 ➔...

  • Page 11: 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 8, object A is not detected because surface S reflects the beam and closes the optical path between the active and passive elements.
  • Page 12 Figure 9 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 13: 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.

  • Page 16: Configuration And Operation Modes

    CONFIGURATION AND OPERATION MODES The JANUS TRX operation mode is selected realizing appropriate connections on the M12 8 poles of the active element (Table 1 and Table 2). AUTOMATICO MODE In this operation mode the OSSD1 and OSSD2 safety outputs follow the barrier status : with proteceted area clear, the safety outputs are active.
  • Page 17 Figure 13 Example of connection of TRX barrier in AUTOMATIC mode without feedback K1K2 MANUAL MODE In this operating mode the safety outputs OSSD1 and OSSD2 are activated (+24VDC) only if the protected area is free and after the reception of the RESTART signal, using a push button or thank to an appropriate control on the SEL_A or SEL_B input (ref.Table 3).

    K1/K2 EXTERNAL CONTACTORS CONNECTION In every operating mode is activable the K1/K2 external contactors feedback. If you want to use this check, connect the pin 4 of 8 poles M12 connector with the power supply (+24VDC) through the series of N.C. contacts (feedback) of external contactors. 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.
