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

DANGER

 DANGER: 

 

Indicates that death or severe personal injury will result if  
proper precautions are not taken.

WARNING

 WARNING: 

 

Indicates that death or severe personal injury can result if  
proper precautions are not taken.

CAUTION

 CAUTION: 

 

Indicates that a minor personal injury can result if proper 

 

precautions are not taken.

!

 ATTENTION: 

 

Warns against actions that can cause damage or malfunction of the 
device, the device environment or the hardware / software result.

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.

  Storage for future reference
