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 drive controllers of the type series VersiComb II 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 devices of the VersiComb II type enable soft start and non-wearing braking of three-phase
asynchronous motors. Their advantages in comparison with direct-on-line starting or star-delta
starting are a torque increase without jerk and a current reduction during the starting phase. The
VersiComb-devices are used for drives that require a soft starting torque in order to protect the
drive components and which, for safety and functional reasons, have to be reliably slowed down.
When the soft start is over, the power semiconductors are bypassed by integrated relays. After
the motor contactor has opened, braking is initiated. An integrated standstill detection switches
the braking current off after the motor has come to a standstill. The fault signaling contact
indicates if the motor has not come to a standstill within the maximum braking time.
Since the standard EN 954-1 calls for a tried and tested component (contactor) in order to cut the
drive power off, a motor contactor has to be connected in series before the combined soft start
and braking device.
Special features
• controlled by microcontroller
• two-phase controlled soft start
• integrated bypass relays
• reduction of starting current peaks
• DC braking via controlled thyristor bridge
• integrated braking contactor
• integrated standstill detection
• monitoring of deceleration time
• suitable for all asynchronous motors
• for snap-on mounting onto 35mm DIN rail
• wide-voltage-range - Option „B“
4. Usage to the intended purpose
The devices of the VersiComb II series are electrical equipment that is used in industrial electrical
power installations. They are designed for application in machines, in order to reduce the starting
torque and starting current peaks and to slow down centrifugal masses on drives with three-
phase induction motors.
Typical applications
• vibrators
• wood working machines
• centrifuges
• drives with large rotating masses
• belt drives

6. Block diagram
7. Functional description (see connection diagram)
After switching on the operating voltage on L1‘, L2‘ (3, 4 in the case of wide-voltage-range
devices, option „B“), the main contactor interlock on the terminals 11, 12 and the operational
status contact on the terminals 9, 10 as well as the fault signaling contact on the terminals 13, 14
are closed. The motor can be started by pressing the ON-key.
After the start, the motor voltage is changed in two phases (L1 and L3) by a generalized phase
control and power semiconductors. Starting out from an adjustable starting voltage
(potentiometer „M“) the motor voltage is steadily increased. The motor torque rises over the
adjusted acceleration time (potentiometer „t“) according to a ramp function up to the maximum
value. When the starting time is over, the power semiconductors are bypassed by integrated
relays and the motor is directly supplied with power from the mains.
The fully automatic run of the braking interval starts with the switch-off of the motor contactor K1
which thereby closes the contact 5, 6. During braking, the motor contactor is interlocked via the
contact 11, 12. After a delay time which, dependent on the amount of the remanent voltage of the
the motor, optimizes itself, the integrated braking contactor pulls in. Afterwards, an adjustable d.c
voltage is applied to the motor winding. The magnetic field resulting from this has a braking effect
on the still rotating rotor. The d.c. voltage is generated with a thyristor phase control. Special
circuits protect the power semiconductors against overvoltage. With the potentiometer „I“ the
braking torque can be adjusted inwide ranges. Experience shows that a braking current 2.5 times
as high as the rated motor current has a good braking effect.
Approx. 1.5s after a motor standstill has been detected, the integrated standstill detection
(adaptable to the drive via potentiometer „n0“) switches the braking current off.

If during the maximum braking time (10s in the case of standard devices) no motor standstill is
detected, the fault signaling contact on the terminals 13, 14 opens and the red „fault“-LED lights
up. When the motor is restarted, this fault indication will be reset. If this fault occurs 3 times in
succession during an operation phase, the VersiComb II goes into fault condition. It is no longer
possible to switch the drive on.
Exceeding of the max. heat sink temperature, a defective or charred ON-key, trigger faults or
synchronization errors as well as reaching of the max. motor temperature (if a motor PTC or a
thermal contact (bimetal) is connected to 7, 8) also cause the VersiComb II to go into this fault
condition which can only be left by remedying the fault and carrying out a mains reset.
By switching the device on, the operational status contact on the terminals 9, 10 is closed, and it
is open from the beginning of the soft start until the end of braking by the standard devices.
By the VC II 400-5,5 ... 15 SO1 devices the operational status contact on the terminals 9,10 is
closed from the end of the soft start until the beginning of the braking.
By the VC II 400-5,5 ... 15 SO3, SO9 devices the operational status contact on the terminals
9,10 is closed from the beginnung of the soft start until the end of the braking.
Warning
To protect the motor and the braking electronics, it is necessary, when
putting the device into operation, to check the braking current with a true
r.m.s. measuring instrument. Simple multimeters and clamp-on probes
produce wrong measurements, since they are only suitable für pure sine-
wave forms and not for phase control.
If, due to the fact that heavy rotating masses are to be slowed down, it is not possible to bring the
motor to a standstill with the permissible maximum braking current (rated device current), a
device of a higher performance category has to be used.

7.1 LED indicators
If, after braking, the „fault“ LED is illuminated and the „bypass“ LED is not flashing, no motor
standstill has been detected. The motor standstill threshold detection has to be adapted as
described in the chapter „Adjusting the standstill threshold“, on page 14.

7.2 Potentiometers
On the front panel there are 4 potentiometers enabling the following adjustments.
7.3 Monitoring functions
Heat sink temperature
Exceeding of the permissible temperature causes a fault.
The motor cannot be started anymore.
Reset after cooling and mains reset.
Motor temperature
Exceeding of the permissible temperature causes a fault.
The motor cannot be started anymore.
Reset after cooling and mains reset.
Trigger failure or synchronization error
A trigger failure/synchronization error causes a fault.
The motor cannot be started anymore.
Reset after fault recovery and mains reset.
Possible fault causes:
• mains phases missing
• motor connection missing
If, despite the fact that the device is correctly connected and the mains voltage is applied, the fault
cannot be remedied, the device is defective.
„t“ Adjusting the starting time:
The starting time can be adjusted in a range from 0.5 – 16s. The adjustment is linear.
„M“ Adjusting the starting torque:
The starting torque can be adjusted in a range from 0 – 80% of the maximum value.
The adjustment is linear.
„I“ Adjusting the braking current setpoint value:
The braking current can be adjusted in a range from 0 – 100% of the rated device
current. The adjustment is linear. From the position of the potentiometer it is possible
to infer the amount of the braking current.
One graduation mark equals 10% of the rated device current.
„n0“ Adapting the standstill threshold in the case of standstill-dependent braking:
The potentiometer „n0=0“ can be used if the braking current is switched off before the
motor has come to a standstill.
„tbr“ In the case of special devices of the SO4 type,no standstill ist detected. With
the potentiometer „t br“, the braking time can be adjusted between 0-25s. The adjust-
ment is linear. The braking time adjusted on „t br“ becomes effective only after com-
pletion of acceleration, and after switching of the by-pass relays. If, after mains reset,
braking is initiated during start-up, a braking time of 20s is automatically adjusted.

10 VC II 230/400-3...15
Check of the start key
A defective or charred key causes a fault.
The motor cannot be started anymore.
Reset after fault recovery and mains reset.
Exceeding the permissible max. braking time
If, after the max. braking time is over, no motor standstill is detected, this leads to a fault (red
„fault“-LED is illuminated).
When restarting the motor, this fault will be reset.
If this fault occurs 3 times in succession during an operation phase, the motor cannot be started
anymore.
Reset after fault recovery and mains reset.
Possible fault causes:
• the adjusted braking current is too small
• despite the fact that the maximum braking current is adjusted, the motor or the centrifugal
mass on the motor is too large
In the latter case, an incorrect device rating was chosen. A device with a higher braking current or
a device featuring a longer braking time has to be used, in so far as this is permissible for safety
and functional reasons.
7.4 Option „B“ – Wide-voltage-range
With this option, it is possible to use VersiComb II-devices within a mains voltage range from
200...480V.
This requires a device supply voltage of 24V AC or 230V AC which has to be connected to the
terminals 3, 4.
If VersiComb II is used as a wide-voltage-range device, the control voltage has to be in the same
range as the supply voltage.
Note: In the case of standard devices this option is not available, even if the
terminals are present.
The requested option and the device supply voltage to be used have to be
expressly indicated when placing the order.
Device supply voltage
- 24V AC
- 230V AC
Control voltage
- 24V DC
In the case of a control voltage of 24VAC,
a special device will be required.
- 230V AC

8.4 Max. Switching frequency
The permissible switching frequency depends on the adjusted starting torque, starting time, the
adjusted braking current and braking time.
During soft start and braking, the power semiconductors in the device are loaded. As a result, the
temperature of the semiconductors increases. For this temperature not to destroy the semi-
conductors but to be passed on to the heat sink, it is necessary that the switching frequency
permissible for the devices is not exceeded.
The values indicated in the tables refer to an operation at maximally possible acceleration and
deceleration times and at maximum braking current.

9. Commissioning
The device is to be put into operation in 3 steps:
1. Mounting
2. Connection and
3. Parameter setting
9.1 Mounting instructions
Caution: Danger to life through electric shock!
The following conditions are to be complied with in order to ensure a safe
and reliable operation of the VersiComb II:
1. The device series VersiComb II is to be used under conditions of the
overvoltage category III.
2. Make sure that pollution degree 2 or better, in accordance with IEC664, is
complied with.
3. The device is to be installed into a housing (min. degree of protection: IP54).
4. The device must be operated without being exposed to contamination by
water, oil, carbon deposits, dust, etc..
Warning:
To avoid heat concentrations, a distance of at least 50mm is to be kept
between cable duct and device.

14 VC II 230/400-3...15
9.2 Connection
VersiComb II is to be installed according to the attached connection diagram.
For other connections please consult PETER electronic GmbH & Co. KG.
Note: Prior to putting the device into operation, the wiring is to be checked.
The usual line and motor protective measures are to be applied. In the case of high switching
frequency it is advisable to monitor, as a motor protective measure, the winding temperature,
since the thermal stress increases and the switching frequency permissible for the motor
decreases.
If motor temperature monitoring is not planned to be implemented, the terminals 7, 8 have to be
connected.
Note: To ensure reliable and safe function it is necessary to comply with the interlo-
cking conditions:
1. To initiate braking, it requires a potential-free normally closed contact of the main contactor,
i.e., when the motor contactor is dropped out, the terminals 5, 6 are connected.
2. The interlocking contact, terminals 11, 12, has to be looped into the control circuit of the
motor contactor K1, so that the motor contactor cannot pull in during braking.
The 24V DC voltage supplied by the device both for checking the normally closed contact of the
main contactor and for motor-PTC detection is not a protection voltage or functional extra-low
voltage and must only be used to its intended purpose.
Caution:
The motor is not physically separated from the mains.
9.3 Parameter settings
Sequence of steps during commissioning:
1. Disconnect the plant/system from the supply mains.
2. Connect an amperemeter between the device (terminal „T1“) and motor terminal „U“.
A moving-iron instrument is required in order to adjust the braking current.
Clamp-on probes or digital multimeters can be used only if they are capable of measuring
the „true r.m.s.“.
3. Turn potentiometer „t“ clockwise to right stop (position 10 on the scale)
4. Turn potentiometer „M“ counter-clockwise to left stop (position 0 on the scale)
5. Turn potentiometer „I“ to a position in the left third (position 2 on the scale)
6. Turn potentiometer „n0“ to left stop (position 0 on the scale)
7. Switch on the mains
8. Start motor by pressing the ON-key

VC II 230/400-3...15 15
Note: When setting up a machine or during commissioning, it is possible to carry
out 5 starts or braking operations in succession, i.e., with rated device
current and at a braking time of 10s. After such operating conditions,
however, the device needs a recovery time of 20 minutes.
Adjusting soft start
Turn potentiometer „M“ clockwise so far that, when pressing the ON-key, the motors starts
immediately. In this connection, humming with the motor being at rest is to be avoided.
Adjust potentiometer „t“ so that the requested starting time or starting characteristic is reached.
Note: To protect the power semiconductors and the motor from excessive heating,
the starting time is to be kept as short as possible. At any rate, the motor
must have reached its nominal speed before the bypass is activated
(„bypass“-LED is illuminated).
Warning:
If the adjusted acceleration time is too short, the internal bypass contacts
close before the motor has reached nominal speed. This can cause damage
to the bypass relays.
Adjusting the braking current
The braking current is to be adjusted to a value as small as possible in order to avoid
unnecessary heating of the power semiconductors and the motor. This is especially important in
the case of high switching frequencies. We recommend to limit the maximum braking current to
2.5 times the rated motor current.
The requested braking torque is to be adjusted with the potentiometer „I". It is important that the
braking current does not exceed the rated device current which is indicated on the rating plate of
the device.
Adjusting the braking time
It is not necessary to make an adjustment, since the braking current is automatically switched off
approx. 1.5s after the motor has come to a standstill.
If during the maximum braking time (10s in the case of standard devices) no standstil is detected,
the braking current will be switched off after this period of time. This is indicated by an opening of
the fault signaling contact. The red „fault“-LED is illuminated.
Caution: Danger to life through electric shock!
Even if the motor is at rest, it is not physically separated from the mains.

16 VC II 230/400-3...15
Adjusting the standstill threshold
Before the first start the potentiometer „n0“ must turn to left stop.
If the braking current switches off before the motor has come to a standstill, turn the
potentiometer in 0,5 steps from „n0=0“ to be found a setting which switches the braking current
after the motor has come to a standstill.
After the motor has come to a standstill the braking current switches off approx. 1,5 s.
Note: The positioning of the braking current as the braking can affect that the
motor standstill is not properly detected. Then control the switched off the
braking current by a second braking.
Warning!
It must be ensured that the specified switching frequency is not exceeded,
otherwise the motor may overheat.

VC II 230/400-3...15 17
10. Dimensioning of pre-fuses
The pre-fuses F can be dimensioned by means of the following instructions.
Basically, two types of fuse protection are available for the user.
1. Fusing according to allocation type „1“, DIN EN 60947-4-2.
After a short circuit, the device is allowed to be inoperative and repair work is possible.
2. Fusing according to allocation type „2“, DIN EN 60947-4-2.
After a short circuit, the device must be suitable for further use. However, there is the
danger that the contacts of the bypass or braking relays weld. Therefore, if posssible,
these contacts are to be checked prior to reconnecting the device to the mains supply. If
this check cannot be carried out by the user, the device has to be returned to the producer
in order to have it checked.
The following dimensioning information refers to the below operating conditions:
• Use of standard asynchronous motors
• Standard starting and/or braking times
• Switching frequency not excceding the value indicated in the data shee
Fusing according to allocation type „1“:
As pre-fuses, we recommend to use line protection fuses (utilization catgory gL) or automatic
circuit-breakers with type K tripping characteristic. In the case of automatic circuit-breakers, the
tripping characteristic of the type series is to be taken into account when protecting the soft start
section. With 2x Inthe tripping time should be at least 20s (I1).
Taking into account the maximally occurring starting current (normally up to the 5-fold rated
device current of the starting section) and the maximally occurring braking current (normally the
rated device current of the braking section), we recommend fuse values according to table 1,
column 4 for the starting section, and column 5 for the braking section.
In the case of special devices having increased starting or braking times, the recommended fuse
value may have to be adapted.
Note: Wiring cross-sectional area according to DIN VDE 0100-430,
DIN EN 57100-430.

18 VC II 230/400-3...15
Fusing according to allocation type „2“:
The power semiconductors are to be protected by fuses of the utilization category gR
(semiconductor protection fuses, high-speed fuses). However, since these fuses do not ensure
line protection, it is necessary to use additionally line protection fuses (utilization category gL).
To protect the semiconductors it is necessary to select gR-fuses featuring cutoff-I²t-values which
are approx. 10-15% below the I²t-value of the power semiconductor (see technical data).
In this connection the fuse rating of the selected fuse should not be smaller that the starting
current to be expected for the soft start section and the braking current to be expected for the
braking section.
PETER electronic does not prescribe the use of semiconductor
protection fuses.
Note 1 On the basis of the I²t-value of the power semiconductors, the starting time,
possibly the max. starting current, braking time, braking current and
switching frequency, the fuse supplier is able to select a suitable type. Due to
the great variety of producers, sizes and types, PETER electronic does not
recommend any particular fuses.
Note 2 If the value of the fuse or the cutoff-I²t-value is selected too small, it may
happen that the semiconductor fuse reacts during the starting phase or
during braking.

10.1 Note on UL/cUL-requirements
To meet the UL-requirements, the VersiComb II has to be connected to the mains voltage via a
`circuit breaker` having an overload release up to Ir= 50A (e.g., Moeller NZMB2-AF50-NA) or
via a `combination motor controller Type E` featuring an overload release up to Ir= 32A (e.g.,
Moeller BK25/3-PKZ0-E + PKZM0-32).
The mains voltage may have a maximum input voltage of up to 480V AC and a short-circuit cur-
rent intensity up to 5000 A.
11. Installation guideline
The VersiComb II is to be installed according to the attached connection diagram. For other
