Observe the following recommendations for secure operation of the product.
General
▪ Ensure that only authorized personnel have access to the device.
▪ Only use the device within an ESP (electronic security perimeter). Do not
connect the device to the Internet in an unprotected state.
▪ Ensure that the device is only operated by trained personnel who are fa-
miliar with IT security.
Commissioning
Observe the following recommendations for device commissioning:
▪ User IDs should be unique and attributable. Do not use a "Group account"
function or an "Auto login" function.
▪ Restrict the rights of the individual user groups as much as is feasible; this
helps avoid errors during operating actions. A user with the "Operator"
role, for example, should only perform operating actions and should not
be able to change any device settings.
▪ Delete or disable the default "admin" user ID. This requires first creating a
new user account with the "Administrator" role. You can then use it to
delete or disable the default "admin" account.
▪ Enable SSL/TLS encryption [►Section 8.2, Page 66]; access to the de-
vice is then only possible using the SSL/TLS protocol. In addition to en-
crypting communication, this protocol also checks the authenticity of the
server.
▪ Use TLS version 1.2 or higher wherever possible.
▪ Integrate the device into a public key infrastructure. Create your own SSL
certificate for this if necessary and then import it.
Operation
Observe the following recommendations during device operation:
▪ Change the password at regular intervals.
▪ Export the security log [►Section 8.17.1, Page 169] at regular intervals.

5 Packaging, transport and storage
5 Packaging, transport and storage
5.1 Packaging, transport and storage
5.1.1 Suitability, structure and production
The goods are packaged in a sturdy cardboard box. This ensures that the
shipment is secure when in the intended transportation position and that
none of its parts touch the loading surface of the means of transport or touch
the ground after unloading.
The box is designed for a maximum load of 10kg.
Inlays inside the box stabilize the goods, preventing impermissible changes
of position, and protect them from vibration.
5.1.2 Markings
The packaging bears a signature with instructions for safe transport and correct storage. The following symbols apply to the shipment of non-hazardous
goods. Adherence to these symbols is mandatory.

5.2 Transportation, receipt and handling of shipments
In addition to oscillation stress, jolts must also be expected during transportation. In order to prevent possible damage, avoid dropping, tipping,
knocking over and colliding with the product.
If a crate tips over, falls from a certain height (e.g. when slings tear) or is
subject to an unbroken fall, damage must be expected regardless of the
weight.
Every delivered shipment must be checked for the following by the recipient
before acceptance (acknowledgment of receipt):
▪ Completeness based on the delivery slip
▪ External damage of any type
The checks must take place after unloading when the crate or transport container can be accessed from all sides.
Maschinenfabrik Reinhausen GmbH 201830 5252433/02 ENECOTAP® VPD® CONTROL PRO
Page 31
5 Packaging, transport and storage
Visible damage If external transport damage is detected on receipt of the shipment, proceed
as follows:
▪ Immediately record the transport damage found in the shipping docu-
ments and have this countersigned by the carrier.
▪ In the event of severe damage, total loss or high damage costs, immedi-
ately notify the sales department at Maschinenfabrik Reinhausen and the
relevant insurance company.
▪ After identifying damage, do not modify the condition of the shipment fur-
ther and retain the packaging material until an inspection decision has
been made by the transport company or the insurance company.
▪ Record the details of the damage immediately onsite together with the
carrier involved. This is essential for any claim for damages!
▪ If possible, photograph damage to packaging and packaged goods. This
also applies to signs of corrosion on the packaged goods due to moisture
inside the packaging (rain, snow, condensation).
▪ Be absolutely sure to also check the sealed packaging.
Hidden damage When damages are not determined until unpacking after receipt of the ship-
ment (hidden damage), proceed as follows:
▪ Make the party responsible for the damage liable as soon as possible by
telephone and in writing, and prepare a damage report.
▪ Observe the time periods applicable to such actions in the respective
country. Inquire about these in good time.
With hidden damage, it is very hard to make the transportation company (or
other responsible party) liable. Any insurance claims for such damages can
only be successful if relevant provisions are expressly included in the insurance terms and conditions.
5.3 Storage of shipments
When selecting and setting up the storage location, ensure the following:
▪ Protect stored goods against moisture (flooding, water from melting snow
and ice), dirt, pests such as rats, mice, termites and so on, and against
unauthorized access.
▪ Store the crates on timber beams and planks as a protection against ris-
ing damp and for better ventilation.
▪ Ensure sufficient carrying capacity of the ground.
▪ Keep entrance paths free.
▪ Check stored goods at regular intervals. Also take appropriate action after
storms, heavy rain or snow and so on.

6.1.4 Information about shielding the CAN bus
In order for the CAN bus to operate faultlessly, you have to connect the
shielding using one of the following variants. If you are not able to use any of
the variants detailed below, we recommend using fiber-optic cables. Fiberoptic cables decouple the devices and are not sensitive to electromagnetic
interference (surge and burst).
Maschinenfabrik Reinhausen GmbH 201834 5252433/02 ENECOTAP® VPD® CONTROL PRO
Page 35
6 Mounting
NOTICE
Damage to the device!
If you connect the CAN bus cable to devices with different potentials, current may flow across the shielding. This current may damage the device.
► Connect the devices to a potential equalization rail to equalize the poten-
tial.
► If both devices have different potentials, only connect the CAN bus cable
shielding to one device.
Variant 1: The connected devices share the same potential
If the devices to be connected share the same potential, proceed as follows:
1. Connect all devices to a potential equalization rail to equalize the poten-
tial.
2. Connect the CAN bus cable shielding to all connected devices.
Variant 2: The connected devices have different potentials
Note that the shielding is less effective with this variant.
If the devices to be connected have different potentials, proceed as follows:
► Connect the CAN bus cable shielding to just one device.

8.4.3 Delay time T1
Delay time T1 delays the issuing of a tap-change command for a defined period. This prevents unnecessary tap-change operations if the tolerance
bandwidth is exited briefly.
Behavior only with delay time T1
8 Operation
If the measured voltage U
is within the set bandwidth , no control
actual
commands are issued to the motor-drive unit for the tap-change operation.
Control commands will also not be issued to the motor-drive unit if the mea-
sured voltage returns to the tolerance bandwidth within the set delay time
T1 . However, if the measured voltage deviates from the set bandwidth for
a long period , a tap-change command occurs after expiration of the
set delay time T1. The on-load tap-changer carries out a tap-change in a
raise or lower direction to return to the tolerance bandwidth.

3. Press the Accept button to save the modified parameter.
Selecting time response T1
You can use this parameter to set the time response for delay time T1. You
can select the following options:
▪ Linear time response
▪ Integral time response
Linear time response With linear time response, the device responds with a constant delay time
regardless of the control deviation.
Maschinenfabrik Reinhausen GmbH 2018 775252433/02 EN ECOTAP® VPD® CONTROL PRO
Page 78
8 Operation
Integral time response With integral time response, the device responds with a variable delay time
depending on the control deviation. The greater the control deviation (ΔU) in
relation to the set bandwidth (B), the shorter the delay time. This means that
the device responds faster to large voltage changes in the grid. Regulation
accuracy improves as a result but the frequency of tap-changes increases
too.

8.4.4 Delay time T2
You can use this parameter to set the delay time T2. Delay time T2 is used
to compensate for large control deviations faster.
The delay time T2 only takes effect if more than one tap-change operation is
required to correct the control deviation. The first output pulse occurs after
the set delay time T1. After the set tap-change delay time T2 has elapsed,
additional pulses occur in order to correct the existing control deviation.
The following requirements must be noted to set delay time T2:
▪ The delay time T2 must be greater than the switching pulse time.
▪ The delay time T2 must be greater than the maximum operating time of
the motor-drive unit.
▪ The delay time T2 must be less than the value set for delay time T1.

8 Operation
Behavior with delay times T1 and T2
Delay time T2 can be used to correct major control deviations more quickly.
Ensure that you set a lower value in the "Delay time T2" parameter than in
the "Delay time T1" parameter.
If the measured voltage U
deviates from the set bandwidth for a long
actual
period , a control impulse is output to the motor-drive unit after the set delay time T1 . If the measured voltage U
is still outside the bandwidth,
actual
delay time T2 starts once delay time T1 is complete. Once delay time T2
is complete, a control impulse is again output to the motor-drive unit for the
tap change to return to the tolerance bandwidth.

8.9 Parallel operation (optional)
Parallel transformer operation is used to increase the throughput capacity or
short-circuit capacity at one location. The device provides you with specific
functions for regulating transformers.
Conditions for parallel
operation
8.9.1 Parallel operation methods
8.9.1.1 Tap synchronization
Compliance with the following general conditions is required for operating
transformers in parallel:
▪ Identical rated voltages
▪ Transformer power ratio (<3:1)
▪ Maximum deviation of short-circuit voltages (UK) for transformers con-
nected in parallel <10%
▪ Same number of switching groups
▪ For parallel operation with CAN communication: Current transformers with
the same rated values must be used for all devices operating in parallel
You can undertake parallel operation with various parallel operation methods.
With the tap synchronization parallel operation method, one voltage regulator works as the master and all others as followers.
Figure65: Tap synchronization
Maschinenfabrik Reinhausen GmbH 2018 975252433/02 EN ECOTAP® VPD® CONTROL PRO
Page 98
8 Operation
The master handles voltage regulation and transmits its current tap positions
to all followers via the CAN bus. The followers compare the tap position received with their own tap position. If the tap position is not the same, the followers switch to the tap position received from the master. This ensures that
the transformers operating in parallel are always in the same tap position.
You can set whether the master transfers the change in tap position to the
followers before or after its own tap-change operation. The devices then either change position sequentially (first the master, then the followers) or in
synch (master and followers at the same time).
If there is a tap difference between the master and followers, the master refrains from issuing any control commands to the motor-drive unit until all of
the followers have reached the same tap position. If the tap difference persists for longer than the set delay time for parallel operation error messages,
the master triggers the Step difference to follower event.
You can explicitly designate the voltage regulators as master and followers,
or set automatic designation using the CAN bus address.
For the tap synchronization parallel operation method, you have to set the
following parameters:

8.9.1.2 Circulating reactive current minimization with CAN bus communication
With the circulating reactive current parallel operation method, parallel operation is carried out using the circulating reactive current minimization
method.
Figure66: Circulating reactive current minimization with CAN bus communication
The circulating reactive current is calculated from the transformer currents
and their phase angles. The voltage regulators in the parallel operation
group share this information via CAN bus. An extra control deviation proportional to circulating reactive current is added to the independently regulating
voltage regulators as a correction for the control deviation determined on the
basis of the measurement voltage. You can use the circulating reactive current sensitivity parameter to decrease or increase this extra control deviation.
The circulating reactive current method is suited to transformers connected
in parallel with a similar nominal output and short-circuit voltage UK and to
vector groups with the same and different step voltages. This does not require any information about the tap position.

Note that the following prerequisites must be met for the "circulating reactive
current minimization" parallel operation method:
▪ You have to use current transformers with the same rated values for all
transformers in parallel operation.
▪ If you wish to operate in parallel operation with existing devices, you have
to activate the Retrofit TAPCON® 2xx parameter.
For the circulating reactive current minimization parallel operation method
with CAN communication, you have to set the following parameters:
▪ Activate parallel operation
▪ Parallel operation method: Circulating reactive current
▪ CAN bus address
▪ Circulating reactive current sensitivity
▪ Circul. reactive current blocking limit
▪ Error if no communication present
▪ Behavior if no communication present
▪ Parallel operation error delay time
8.9.1.3 Circulating reactive current minimization without CAN bus
communication
With this method, you can operate several voltage regulators without a communication connection (CAN bus) in parallel with circulating reactive current
minimization.
Figure67: Circulating reactive current minimization without CAN bus communication
The circulating reactive current is calculated using the desired power factor
parameter, the desired load stress type parameter, and the measured transformer current. An extra control deviation proportional to circulating reactive
current is added to the independently regulating voltage regulators as a correction for the control deviation determined on the basis of the measurement
voltage. This extra control deviation depends on how much the measured
power factor deviates from the desired power factor.
