2.13 Safety-related instructions
●
The instructions listed below must be followed to prevent
destruction, damage and malfunction of the measuring system and
downstream electronic devices.
– Wiring work may only be carried out and electrical connections only be
opened and closed while the system is de-energized.
– Voltages equal to the supply voltage at the additional incremental
interface output. Ensure the ground reference point is present at all
times, respectively the organization responsible for the system must
provide appropriate protective measures for downstream electronic
devices.
– Cable outlets of mating connectors must always be secured with a
cable grip against pulling out.
– Do not carry out any welding work after the measuring system has
already been wired or switched on.
– Ambient temperature values may never fall below or exceed the
permissible limit values; this must be ensured by taking the
appropriate heating/cooling measures at the place of installation.
– The measuring system must be installed such that it is not exposed to
any direct moisture.
– Suitable aeration/ventilation and heating/cooling measures must be
taken at the place of installation to prevent the temperature falling
below the dew point (condensation).
– Potential hazards resulting from interactions with other systems and
equipment which are or will be installed in the vicinity must be
determined. The user is responsible for taking appropriate measures.
– Voltage supply must be protected with a fuse suitable for the supply
lead cross-section.
– Cables used must be suitable for the temperature range.
– If defective, the measuring system may not be operated.
– Make sure that the installation environment is protected from
aggressive media (acids, etc.).
– Avoid shocks (e.g., hammer blows) to the shaft during installation.
– It is prohibited to open the measuring system.
– After having set the address switches and LEDs, ensure that they are
no longer accessible by firmly closing the access with the screw plug.
– Connector plugs of the measuring system that are unused during
storage and/or operation of the system have to be provided either with
a mating connector or a protective cap. The IP degree of protection is
to be selected according to requirements.
– The nameplate specifies the technical properties of the measuring
system. If the nameplate is no longer legible or is completely missing,
the measuring system may no longer be put into operation.
– The measuring system cannot detect a break in the coupling or the
torque arm. The operator must include this circumstance in the safety
concept of the system.
