2. SAFETY NOTICES
2.1. OPERATOR SAFETY
It is the responsibility of the user's organization to ensure that the AT3600 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 Micr- Screen
(light curtain) will provide only part of the complete safety function that is required.
The AT3600 and light curtain must be installed by a designated, qualified safety person
who will conduct an overall assessment of the risks involved and provide operator
training, safety notices, and further safety equipment as well as install the AT3600 and
light curtain in accordance with local regulations.
When conducting a risk assessment and providing operator training and notices, it
should be noted that the first safety feature of the AT3600 is the yellow indicating light
on its front panel. This light will be lit when the AT3600 is running a test and may be
generating dangerous voltages. (External indicating devices can also be used to show
that the AT3600 is in a hazardous condition. See the 'Remote Port' description in the
AT3600 user manual.) The operator should not attempt to touch the part under test or
enter the safety enclosure when the yellow light is illuminated. The light curtain then
provides supplementary safety protection against accidental entry into the safety
enclosure by the operator.
2.2. THE SAFETY ENCLOSURE
Clearly, any safety system should be thought of providing a total ‘safety enclosure’
which prevents access from all sides to the dangerous voltages on the transformer under
test. It is also clear that the infrared safety system can only provide one side of this
safety enclosure - that which faces the operator.
If there is a danger that an operator or any other person could touch the transformer
under test from either the side or the rear of the tester, then you must also take steps to
prevent this, either by installing suitable physical barriers, or for example, by
positioning the tester in the corner of the room so that existing walls prevent access to
the transformer from the side and rear. The two vertical columns of the IR safety
system would then normally be placed touching the physical barriers, which form the
side-walls of the safety enclosure.
If there is any danger that the operator could touch the transformer under test from
above, then further precautions should be taken to provide physical barriers to guard
against this.
