1.2. RECOMMENDED SAFETY SYSTEM.
For optimum safety, ease of use and test speed, Voltech recommends the use of a safety
light curtain with the AT3600 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.
Once the operator has placed a transformer on the test fixture, and removed his or her
hand, the light curtain can signal that the situation is safe within a few tens of
milliseconds. However, if the operator tries to touch the transformer during program
execution, the safety system will open the safety interlocks (also within a few tens of
milliseconds), so that the tests with dangerously high voltages will not be run.
The Safety Interlock Cable is an accessory that makes connection between the AT3600
and a safety light curtain as safe and easy as possible. The cable has been optimised 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:
• Voltech Safety Interlock Cable
(See next section)
• Banner ‘Micro-Screen’ safety light curtain
• 1 off USCD-1T2 Metal Box Controller
• 1 off USE2424YI Yellow Emitter 610mm high with 150mm to 9m range.
• 1 off USR2424YI Yellow Receiver 610mm high with 150mm to 9m range.

NOTE: The Banner part numbers were correct in 2004. You are strongly advised to
consult with your safety system supplier before making purchase decisions. Similar
safety systems are available from many other manufacturers and may be suitable.
