Page 4: Safety Remarks
This manual must be read and understood before installation and setup. The VersiSafe is suitable to operate as a part in safety circuits of a plant or machine. Usually also other components are part of these circuits. 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. -

Page 6: Function
VersiSafe Function The VersiSafe is connected to the motor terminals and measures the induced back emf voltage of a freewheeling motor. 2 redundant measuring channels are used (L2-L1 and L3 L1). If the back emf voltage drops to 0 simultaneously in both channels this indicates standstill and the output relay is energised. -
Page 7: General Description
• Width 45 mm Funtion The VersiSafe can be used for standstill detection on all 3-phase, single phase and DC motors, that generate a voltage caused by remanence when freewheeling. As the voltage level Uan for standstill monitoring and the time delay t , after detection of standstill until the safety relays are switched on, are adjustable, the function can be adopted to different motors and applications. - Page 8 VersiSafe Terminals and settings L1 - L2 - L3: connection to monitored motor 11 - 12: safety contacts (NO) 23 - 24, 33 - 34, 43 - 44: safety contacts (NC) 53 - 54: monitoring contact (C/O) X1 - X2:...

Page 9: Functional Diagram
If semiconductor monitoring outputs are used, their supply voltage must be connected to A3(+)- A motor connected to the terminals L1-L2-L3 of the VersiSafe generates a voltage when running down (motor is switched off). The voltage is proportional to the speed and caused by residual magnetism (remanence). -
Page 10: Technical Data
This is done with the feed back circuit (terminals X1-X2) to which the NC contacts of the contactors/components must be connected. (see also wiring diagrams). The VersiSafe will only enable its safety output if the feedback loop X1-X2 is closed while stand- still is detected, i.e. the external contactors/components are in initial state (NC contacts are closed). -

Page 18: Special Applications And Operation Notes
An open connection will result in broken wire indication and disable the safety contacts. When connecting the VersiSafe to a 3-phase motor with star delta starter the star contactor must be energised while the motor is switched off, in order to achieve closed circuits between L1-L2-L3... - Page 19 If it is not possible to switch in the star contactor after the motor is switched off, the measuring inputs of the VersiSafe have to be connected like a single phase connection. L2-L3 are bridged and connected to one end of a motor winding and L1 to the other end of the same winding.

Page 20: Failure Monitoring
Failure monitoring Types of error The VersiSafe includes a number of facilities to to detect failures that could influence the safety function of the module. The failure check is carried out on power up of the unit and in cycles during normal operation. -
Page 21: Failure Indication
VersiSafe Potentiometer error To achieve the required safety when adjusting the voltage threshold for standstill detection, ech setting function is realised with 2 potentiometers having one common setting knob. If on 2 corres- ponding potentiometers a different setting is detected the potentiometer error U or t displayed. -

LED „UH“ lights green? If yes, go to 2. If no, U has undervoltage or the unit has an internal device failure. (Internal failures can occur in the case of undervoltage, welded safety output contacts or seldom because of interference) switch supply voltage off and on.

Possibly the interruption comes from disre- garding the operating remarks for motors with switchable windings (see remarks).
