S
As commissioning engineers or service engineers,
they have successfully completed the training to qual­
ify them to repair the automation systems. They are
also authorized to activate, ground and label circuits
and equipment in accordance with safety engineering
standards.
Working safely
S
The transducer must not be directly connected to the
power supply system. The supply voltage must be
between 12 and 30V
DC
.
S
Error messages should only be acknowledged once
the cause of the error is removed and no further dan­
ger exists.
S
Maintenance and repair work on an open device with
the power on may only be carried out by trained per­
sonnel who are aware of the dangers involved.
S
Automation equipment and devices must be designed
in such a way that adequate protection or locking
against unintentional actuation is provided (e.g.
access checks, password protection, etc.).
S
For those devices operating in networks, safety pre­
cautions must be taken both in terms of hardware and
software, so that a line break or other interruptions to
signal transmission do not cause undefined states or
loss of data in the automation device.
S
After making settings and carrying out activities that
are password-protected, ensure that any controls that
may be connected remain in a safe condition until the
switching performance of the device has been tested.
