1.3.10 Operator Safety
The AT3600 is capable of generating high voltage test signals that could cause operator injury.
The AT3600 design includes a Safety Interlock connector on the rear panel. The safety interlocks must be properly connected before any high voltage test is allowed to execute.
1. For a test situation that only uses low voltage tests, the tester will operate satisfactorily without any safety interlocks. Low voltage tests include:
- Winding Resistance
- Winding Inductance (Series or Parallel)
- Q Factor
- Equivalent Resistance (Series or Parallel)
- Leakage Inductance
- Interwinding Capacitance
- Turns Ratio
2. For manual operation, if high voltage tests are required, the Voltech safety system is recommended. This is based around the use of Infra Red light beams to provide a safety curtain, and has the advantage of not slowing test throughput. The following are some of the tests which will not function without a safety system:
- Insulation Resistance
- Magnetizing Current
- Open Circuit Voltage
- Hi-Pot (DC) & (AC)
- Hi-Pot Ramp (DC) & (AC)
3. Alternatively, you may construct your own safety system based on a mechanical barrier fitted with safety switches.
In a robotic situation, this could take the form of a walled off area with the interlocks in the door.
