1. Safety notes
The described devices are electrical equipment for use in industrial electrical power
installations. An impermissible removal of the covers during operation can cause
serious damage to your health, since these devices contain live parts with high
voltages.
Adjustment work may only be performed by trained staff observing the safety regulations.
Assembly and mounting work may only be carried out with the equipment deenergized.
Make sure that all drive components are properly earthed.
Please read these commissioning instructions carefully before putting the device into operation.
Besides, the user must ensure that the devices and associated components are fitted and
connected in accordance with the appliable local, legal and technical regulations. The VDE-
regulations VDE 0100, VDE 0110 (EN 60664), VDE 0160 (EN 50178) , VDE 0113 (EN 60204,
EN 61310),VDE 0660 (EN 50274) plus the appropriate regulations of the TÜV (Technical Control
Association) and the trade associations apply in Germany.
The user must ensure that the drive turns into a safe operating state following a device failure, in
the event of maloperation, or if the control unit has failed etc..
Caution: Even if the motor is at rest, it is not physically separated from the mains.
2. Conformity
In industrial linguistic usage the electronic brakes of the type series VersBrake…-L (LP) are called
„devices“, however, in the sense of the „law on the safety of equipment“, 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
guidelines 2006/42/EC (Machinery directive) and 2006/95/EC (Low voltage directive) is not
proved.

3. General description
The electronic braking devices of the VersiBrake-L-type are available both as a housing version
and as a circuit-board version (LP). They enable non-wearing braking of three-phase
asynchronous motors and mono-phase motors. The braking devices are used for drives that, due
to safety and functional reasons, have to be reliably slowed down. Braking is initiated by
measuring the motor voltage. It is not necessary to connect the motor contactor contact, but this
is possible if double detection (redundant system) is required. An integrated standstill detection
function switches the braking current off after the motor has come to a standstill.
Various fault conditions are indicated via LEDs and, in the case of the circuit-board version, additi-
onally via a fault signalling contact.
Special features
• controlled by microcontroller
• wear-resistant and maintenance-free
• for three-phase asynchronous motors
• for mono-phase motors
• retrofitting into existing plants possible
• no normally closed contact on motor contactor required
• integrated braking contactor
• printed circuit-board version with fault signalling contact
• automatic remanence time optimization
• integrated motor standstill detection
• integrated overload monitoring
• braking current control
• meets trade assoc. requirements for PL = b,
acc. to DIN EN ISO 13849-1
4. Usage to the intended purpose
The devices of the VersiBrake…-L (LP)-series are electrical equipment that is used in industrial
electrical power installations. They are designed for application in machines, in order to slow
down rotating masses on drives with three-phase a.c. motors.
Typical applications
• sawing machines
• centrifuges
• wood working machines
• conveying systems
• textile machines

7. Functional description (see connection diagram)
After the operating voltage on 1L1 (L1) and 3L2 (L2) has been switched on, the main contactor
interlock X5 (X5), X6 (X6) and, in the case of the circuit-board version, the fault signaling contact
(X10), (X11) closes. The motor can be started.
A starting logic makes sure that, when switching the plant on with the master switch while the
motor is still switched off, braking is not initiated.
The fully automatic run of the braking interval starts when a drop of the motor voltage is detected
on the terminals 2T1 (T1), 4T2 (T2) and 6T3 (T3). During braking, the main contactor is inter-
locked via the contact X5 (X5), X6 (X6). After a delay time which, dependent on the amount of the
remanent voltage of the motor, optimizes itself, the integrated braking relay pulls in. After the
contact bounce time has been waited out, a controlled d.c. current is fed into the motor winding.
The magnetic field resulting from this has a braking effect on the still rotating rotor. The d.c.
current is generated by a thyristor phase control. Special suppressor circuits protect the power
semiconductors against overvoltage. With the potentiometer I (P2), the braking current (and thus
the braking torque) can be adjusted within a range of 10 … 100% of the rated device current. The
integrated motor standstill detection, which, if the 6T3 (T3)-terminal is connected, functions via
the amount of the remanent voltage and, if the 6T3 (T3)-terminal is not connected, via the brake
current waveform, switches the braking current off approx. 1.5s after a motor standstill has been
detected. To be able to adapt the device to a variety of motors, it is possible to adjust the stand-
still threshold via the potentiometer n0 (P1).
Faults, that occur during braking, are indicated via a signaling light (LED), and, in the case of the
circuit-board version, additionally via a fault signaling output (X10), (X11).
If more safety (redundant system) is required for initiating braking, it is possible to additionally
connect a normally closed contact of the motor contactor to the terminals X3 (X1), X4 (X2). Then,
braking will be initiated by two processes which are independent of each other.
Warning:
To ensure a reliable standstill detection function, it is necessary to comply
with the following:The braking current must not exceed (3) three times the
amount of the rated motor current. The VB …-L (LP) must be operated with
the 6T3 (T3)-terminal being connected for feedback.
If the VB-L is operated without the 6T3 (T3)-terminal beeing connected,
which always applies in the case of single-phase applications, it is to be
ensured that braking current flows at least for a period of 1.5 s before the
motor comes to a standstill, as no motor standstill is detected within this
period of 1.5s and the braking current would then flow over the total
maximum braking time. This could cause destruction of the motor and fault
indications of the braking device.
Note: If the braking time at rated device current is too short, due to the fact that the
centrifugal masses to be slowed down are too large, either a device with a
longer braking time can be inquired of the producer or a device featuring a
higher rated current has to be used.

8. Control inputs and outputs
8.1 Control input
Information on operation without connected starting contact:
The braking delay time (remanence time) may prolong itself by up to 50%.
The interlocking relay does not open immediately after the motor contactor has dropped out, but
only shortly before the braking relay closes. In contrast to an operation with connected starting
contact this means that the motor can be restarted during the braking delay time (remanence
time).
Caution: Danger to life through electric shock!
The terminals X3 (X1), X4 (X2) carry mains potential; when laying the
connecting lines, be sure to provide protection against accidental contact.
Control terminals Designation Description
X3 (X1), X4 (X2) Starting contact Connection of a normally closed contact of the motor
contactor.
In standard applications not required.
Connection is only required, if more safety is required
(redundant system) to initiate braking.
