  • Page 4: Introduction

    NFRA AFETY YSTEM For optimum safety, ease of use and test speed, Voltech recommends the use of a safety light curtain with the AT5600 and other Voltech products that can generate dangerous voltages during routine production testing. This provides a ‘light curtain’ of infrared beams positioned in front of the tester.
  • Page 5 The cable has been optimized for use with the ‘Banner’ safety light curtain described below, but safety light curtains from other manufacturers may also be suitable. To construct a complete safety system, you will need: From Voltech 250-030 Safety Interlock Cable From Banner 1 off ‘EZ-Screen’ safety light curtain 1 off EZAC-R9-QE8 AC Interface Box...

  • Page 6: Description

    ESCRIPTION The Safety Interlock Cable is a robust and convenient way of connecting the AT5600 and other Voltech products to a safety interlock system. Although other safety systems may be suitable, the cable has been optimized for direct and quick connection to the Banner product described in the previous chapter.

  • Page 7: Principle Of Operation

    2.2 P RINCIPLE OF PERATION The cable carries 3 pairs of color-coded wires. Each pair must be linked together by the safety system before the AT5600 will operate a high voltage test. If any one of the three pairs become un-linked during a test, the AT5600 very quickly switches off any high voltage that is being produced.

Primary power to Yellow Main power-breaking the high voltage relays (Final Switching Blue generators is Device) of the safety passed through system. The black link is pins 3 and 7 used to series 2 relays, if required.
  • Page 9 IR S NSTALLING THE AFETY YSTEM 3.1. OSITIONING THE IGHT URTAIN The light curtain should be positioned in front of the tester, extending well beyond the width of the tester so that the operator is not impeded when he/she has to load and unload the transformer under test.

    3.2. MPORTANT PERATOR AFETY It is the responsibility of the user's organization to ensure that the AT5600 and its associated safety systems are installed, maintained, and operated in accordance with all safety guidance and legislation that may be in force locally. The BANNER EZ-Screen (light curtain) will provide only part of the complete safety function that is required.
  • Page 12 Failure to do so could result in personal injury. Consult the user manual supplied with the light curtain for up-to-date information. 1) Voltech Safety Interlock Cable (250-030) preparation: a) Cut the plastic tie-wrap joining the Blue wire and the Black jumper wire. The Black jumper wire is not required for Banner Model Number EZAC-R9-QE8 installation.

Refer to Figure 3 Figure 3 3)Remove the lid from the Banner AC Interface Box. 4) Identify the terminal block, P1, P2, and P5, inside the Banner AC Interface Box. Also identify the EDM slide switch.
  • Page 14 6) Fit the two Shorting Links provided with the Banner AC Interface Box into terminal block P1 as followed; Refer to figure 5B a.) short X1 to X2 b.) short X3 to X4 Figure 5A Figure 5B 7) Set the EDM Slide Switch to 2-CH EDM position. Refer to figure 6. Figure 6 8) Fit the cable gland for the Safety Interlock Cable onto the top hole of the Banner AC Interface Box.

    ESTING THE AFETY YSTEM 4.1. ECOMMENDED AILY HECK Testing of the safety system, which may include checking any physical barriers in the total safety enclosure surrounding the tester, should be supervised by your designated, qualified person responsible for operator safety. The following tests must be carried out during installation of the light curtain and at periodic intervals, normally daily, as determined by the designated safety person: Check the integrity of the complete safety enclosure including warning notices and...

  • Page 18: Quick Check - Complete System

    – C 4.2. UICK HECK OMPLETE YSTEM The above process will check the action of the light curtain on its own. To check the operation of the complete system (i.e. to confirm that the interlock signals are correctly understood by the AT5600) you can use the interlock icon on the display of the AT5600. Repeat the above tests with the rod and observe the Icon on the front panel of the AT5600.

  • Page 19: Operating The At5600 With The Ir Safety System

    AT5600 IR S PERATING THE WITH THE AFETY YSTEM For a description of the use of the Light Curtain with the AT5600, please see the AT5600 user manual (98-119) chapter 6. Chapter 6.5 describes the operating and warning messages that may be observed on the AT5600 when it is being used with a safety light curtain.

  • Page 20: Constructing Safe Fixtures

    ONSTRUCTING IXTURES As described in the previous section, when the light curtain of the safety system is broken, the tester will stop the execution of a high voltage test, and remove the dangerous voltages, to protect the operator from the dangers of electric shock. This may sound a simple operation, but in fact it is not.
