For optimum safety, ease of use and test speed, Voltech recommends the use of a
safety light curtain.
This provides a ‘light curtain’ of infrared beams positioned in front of the test
environment. Once the operator has removed his hand, the light curtain can signal that
the situation is safe within a few tens of milliseconds. However, if the operator breaks
the light curtain during testing, the safety system will open the safety interlocks (also
within a few tens of milliseconds), so that the DC1000 output will cease.
Voltech can provide a cable for connection between a light curtain and the DC1000 or
AT transformer tester. 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. (out part number 250-030)
To construct a complete safety system you will need:
Voltech Safety Interlock Y lead (250-031).
Voltech Safety Interlock Cable (250-030)
