1. Safety remarks
Installation and setup of the VersiSafe must only be carried out by well trained staff,
with knowledge about all relevant standards for safety, accident avoidance and
control circuits. 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.
Also the correct tripping point and time delay setting of VersiSafe suitable for the application is in
the liability of the user.
When stocking, transporting and operating the VersiSafe the conditionsstated in the technical
data must be observed. Defective units must not be operated. Opening a device or making
unauthorised changes can influence the safety function and finish warranty.
When switching capacitive or inductive load over the output contacts appropriate protection
should be provided in order not to overload the contacts. In addition a fuse must be provided to
protect the contacts against welding (see technical data).
The unit should be panel mounted in an enclosure rated at IP 54 or superior. Dust and dampness
may lead to malfunction
Risk of fire or other thermal hazards!
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.
2. Conformity
In industrial linguistic usage the Safety Standstill Monitor of the type series VersiSafe are called
"devices", however, in the sense of the "device-safety-law", the "EMC-law" or the "EC machinery
directive" they are not devices or machines ready for use or connection but they are components.
It is only possible to define their final function, when these components are integrated into the
design and construction of the user.
To be able to use the devices to their intended purpose, it requires power supply networks
according to DIN EN 50160 (IEC38).
The user takes the responsibility that the user’s design and construction comply with the appli-
cable legal provision.
The commissioning is strictly forbidden as long as the conformity of the final product with the
guideline 2006/42/EC (Machinery directive) is not proved.

4. 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.
To adopt the unit to all different types of motors and applications the voltage threshold indicating
standstill on VersiSafe is adjustable. Also the time delay between detection and energisation of
the relay is adjustable (standstill time ts).
In addition the unit detects broken wire on the measuring inputs L1 / L2 / L3. If broken wire is
detected the output relays goes into safe state (as with running motor). This state is stored and
can be reset by bridging terminals X3-X2.
The input signals of both channels are permanently compared. If the signals are different for more
then 2.5 sec a simultaneity failure isdetected. This failure resets when both input channels
receive simultaneous signals with the same level.
To the terminals X1-X2 the feedback circuit of external contactors (used for contact
reinforcement) is connected (NC contact). If no feedback circuit is required, these terminals must
be linked. Open terminals will cause a failure message.

Warning:
The terminals X1 - X2 - X3 has no galvanic separation to the measuring ciruit
L1 - L2 - L3. They must be controlled with volt free contacts.

5.3 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 ts, after detection of standstill until the safety relays are
switched on, are adjustable, the function can be adopted to different motors and applications.

5.4 Functional diagram
5.5 Functional description
The auxiliary voltage is connected to the terminals A1-A2; the LED „UH“ lights up green. On
undervoltage or missing auxiliary supply the safety outputs are disabled.
If semiconductor monitoring outputs are used, their supply voltage must be connected to A3(+)-
A4.
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).
This voltage is measured redundant on 2 input channels via the terminals L2 and L3 with L1 as
common reference.
If the voltage drops on both channels below the adjusted value Uan, the unit detects standstill.
When the terminals X1-X2 of the feedback circuit are bridged and the time delay ts is finished, the
safety contacts 23-24, 33-34 and 43-44 close while contact 11-12 opens. All 4 contact paths have
2 positive guided contacts of 2 safety relays wired in series.

At the same time the monitoring relay energises (53-54 closes), the semiconductor output „ON“ is
switched on and the LED „OUT“ lights green. During time delay ts this LED flashes.
If the voltage measured on terminals L1-L2-L3 of VersiSafe rises over the adjusted value plus
hysteresis in at least one channel (the motor is switched on or the shaft turns mechanically), the
positive guided output contacts are switched off immediately (contacts 23-24, 33-34 and 43-44
open while contact 11-12 closes). The monitoring relay de-energises (53-54 opens), the semicon-
ductor output „ON“ goes off and the LED OUT“ lights yellow (= Uan over adjusted value).
Feedback circuit X1 - X2
If the safety contacts control external contactors/components (e.g. to re-enforce or multiply the
contacts) the safety function of them must be monitored.
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).
The feedback circuit X1-X2 must be closed as long as the safety outputs because of running
motor or external failure) are not enabled. If not the failure „feedback circuit“ is indicated.
If the feedback circuit is not used, the terminals X1-X2 must be bridged.
