Safety Notes
WARNING
Risk of electrocution!
Danger to life or risk of serious injuries.
• Disconnect the system and device from the power supply and ensure
they remain disconnected during electrical installation.
• The device may only be used for the applications described in the mu-
tually applicable operating instructions / data sheet. The notes in the
respective documentation must be heeded. The permissible ambient
conditions must be observed.
• The contact protection of the elements connected and the insulation of
the supply cables must be designed in accordance with the requirements
in the operating instructions / data sheet.
• Note the VDE and local regulations, particularly those related to protec-
tive measures.
• The terminals X1 - X2 - X3 has no galvanic separation to the measuring
ciruit L1 - L2 - L3. They must be controlled with volt free contacts.
WARNING
Risk of fire or other thermal hazards!
Danger to life, risk of serious injuries or property damage.
• The device may only be used for the applications described in the mutually
applicable operating instructions / data sheet. The notes in the respective
documentation must be heeded. The permissible ambient conditions
must be observed. In particular, the current limit curve must be heeded.
• The device may only be installed and put into operation by experts who
are familiar with this technical documentation and the applicable health
and safety and accident prevention regulations.
WARNING
Functional error!
Danger to life, risk of serious injuries or property damage.
• The device may only be used for the applications described in the mu-
tually applicable operating instructions / data sheet. The notes in the
respective documentation must be heeded. The permissible ambient
conditions must be observed.
• The device may only be installed and put into operation by experts who
are familiar with this technical documentation and the applicable health
and safety and accident prevention regulations.
• The unit should be panel mounted in an enclosure rated at IP 54 or
superior. Dust and dampness may lead to malfunction.
WARNING
Installation fault!
Danger to life, risk of serious injuries or property damage.
• Make sure of sufficient protection circuitry at all output contacts for
capacitive and inductive loads.
!
Attention!
• The safety function must be triggered during commissioning.
•
It is the liability of the builder of the plant or machine to guarantee the
complete safety function by selecting the correct components, wiring and
operation.
Also the correct tripping point U
an
and time delay setting t
s
of UG 6946
suitable for the application is in the liability of the user and has to be
determined by testing the system under worst case conditions.
If e.g. the motor current is run down slowly using a frequency inverter
or a softstop unit, a de-magnetisation of the motor can take place. It is
necessary to check if the remaining remanence voltage is sufficient to
guarantee a correct and safe standstill monitoring. At high frequencies
an increasing damping of the measuring inputs has to be taken into
account (see technical data Measuring input „response value dependant
on frequency“).
• Opening the device or implementing unauthorized changes voids any
warranty

Symbol and Notes Statement
The installation must only be done by a qualified electrican!
Do not dispose of household garbage!
The device must be disposed of in compliance with nationally
applicable rules and requirements.
To help you understand and find specific text passages and notes in the
operating instructions, we have important information and information
marked with symbols.
Before installing, operating or maintaining this device, these in-
structions must be carefully read and understood.
The product hereby described was developed to perform safety functions
as a part of a whole installation or machine. A complete safety system
normally includes sensors, evaluation units, signals and logical modules
for safe disconnections. The manufacturer of the installation or machine
is responsible for ensuring proper functioning of the whole system. DOLD
cannot guarantee all the specifications of an installation or machine that
was not designed by DOLD. The total concept of the control system into
which the device is integrated must be validated by the user. DOLD also
takes over no liability for recommendations which are given or implied in
the following description. The following description implies no modification
of the general DOLD terms of delivery, warranty or liability claims.
General Notes
Designated Use
The UG 6946 is used for standstill detection on motors without sensors.
• Standstill detection in safety circuits according to IEC/EN 60204 in
machines with dangerous parts or tools to enable protection systems.
• To avoid damage if unexpected start can cause collision.
• Motor control when reversing direction.
When used in accordance with its intended purpose and following these
operating instructions, this device presents no known residual risks.
Non observance may lead to personal injuries and damages to property.
