INSTALLATION AND CONNECTION
Only qualified staff is allowed to perform the installation. Also there have to be
kept all valid rules from government! Before connecting the device check that all
lines are without voltage and shorten current transformer.
1) Compare auxiliary-, measurement-, control voltage, frequency and the current path of the device
(see type label) with the data of the electricity network.
2) Assemble the relay in the switch panel with the 2 mounting clips. If the device is not fitting in
the cut out the small plastic bars on the side of the case can be removed with a knife.
3) Connect protective ground to the terminal link of the case.
4) Connect in accordance to the wiring diagram. Pay special attention to the cross section size of
the CT connections! A combined power supply and measurement ensures a safe shutdown of
capacitors at low voltage.
5) Remove short circuit links of the current transformer

2 COMMISSIONING
2.1 ESTAmat PFC-N is parameterized:
After the supply voltage is applied, in ESTAmat PFC-N starts a countdown with 90 sec. Cancel the
countdown by pressing the e(esc) button or expire the countdown. After expiring the countdown,
starts the adjusted discharge time for the capacitors (default 75 sec.). Only then the regulations
starts with preset parameters.
2.2 ESTAmat PFC-N is not parameterized:
During the countdown, the auto-initialization can be start by pushing the f( ) button. The
regulator determine which control outputs are not used and blocks them. A wrong connection of
voltage and current will be determined and corrected. After expiration of the auto-initialization, the
controller start the regulation and recognize automatically the step sizes of the capacitors. Settings
of c/K value and the switching sequence is not required.
When mains conditions are not suitable for auto-initialization, it will be interrupted. The controller
shows the message
„Ai Abrt“. If multiple repetition do not lead to any result, the following chapters shall be
considered.
Display „Auto“: Indication „Auto“ shows that the control is working. If „Auto“ is not displayed
then control function is stopped. This can happen for the following Reasons: manual mode is active,
control function is switched off, temperature is to high, measured current is less than 15mA, voltage
or the harmonic content is outside the admissible range.
Over-and undervoltage monitoring: The ESTAmat PFC-N is equipped with an over and
undervoltage monitoring. The admissible voltage range refers to the adjusted nominal voltage. If the
measured voltage is outside of the admissible range the message U Alarm appears. Then the setting
of nominal voltage has to be adapt to local ratings. The nominal voltage is independent of the
connection always the line voltage.
Activation of the measured value display: see chapter 4.1

Strong voltage commutation notches can, in spite of the internal
filtering, result that automatic synchronization is disturbed.
This could result in large measurement errors. For this reason the
following settings can made.
Automatic synchronization:
For maximum accuracy at mains voltage without commutation
notches.
FIX-50HZ: For safe operation in the 50Hz grid with extremely poor
power quality.
FIX-60HZ. For safe operation in the 60Hz grid with extremely poor

"YES" for an optimal compensation result, the controller can switch
off active steps and replace them with more suitable steps.
"NO" This function is deactivated.
This function is useful when different step sizes are available. If all
available step have the same step size, then this feature should be
disabled otherwise is may lead to unnecessary switching cycles.
308
Step recognition "OFF"
Yes/No
"YES": Step sizes have to be programmed by hand. The step sizes
have to be programmed by hand if:
a) there is in the system quickly changing loads and problems
with the automatic step size detection occurs.
b) the automatic detection of defective steps is not desired.
c) the contactors have a delay of more than 200msec.
"NO" Step sizes are automatically determined during operation and
losses of step sizes were tracked and considered at the control.
309
Blocking of defective capacitors
Yes/No
"YES" If a step is switched in three times without measurable
network reaction, the controller is blocking the step and doesn't use
it for the control.
Is a Step recognized to be defective, blinks in the display the
corresponding output and in the step database and menu "403" it's
displayed as step type "flty".
"NO" Steps are connected even if no network reaction is
measurable. This results unnecessary switching cycles.
Steps that are stored as defective will be tested every 24 hours or
after the controller is restarted.

1/2/3/4
Control algorithm
1. Automatic: The controller operates on the "Best Fit"
principle. This means the controller compares before each
switching operation, all in the step database stored step sizes
with the identified need for reactive power and choose
always the step which is the closest to the control target. If
the controller has several equal steps available, the number
of switching cycles automatically distributed to these steps.
2. LIFO: „Last In, First Out“ Switch on the outputs is always
done in the switching sequence 1-2-3-4-max. The switch off
is in the switching sequence been turned upside max-4-3-2-1.
3. Kombifilter: Special algorithm for combined filter banks.
The controller operates on the "best fit" principle as in
automatic mode. Unlike to automatic mode the controller is
connecting always at least the same or more capacitance
which is connected to the odd numbered outputs with the
even numbered outputs. If the controller has several equal
steps available, the number of switching cycles automatically
distributed to these steps.
4. Progressive: The controller switches if required, several
steps in sequence with a shorter switching time. From
software 1.04, the controller uses independently of the set
switching time always 1 sec. as switching time. Furthermore,
the automatic step size detection is disabled and the step
sizes need to enter by hand. The input of the step sizes
should be as accurate as possible, because the regulator
would otherwise tend to oscillate. Leaving the "Progressive"
algorithm and use a different algorithm, the set switching
time is used the step size detection is re-enabled.
312
Offset reactive power
The set here offset reactive power is always added to the measured
reactive power. This means that the system can be capacitive, but
measurement of the utility records the required Pf. The set offset
reactive power also goes into the calculation of ▲Q, Pf, apparent

Discharge time
0,5...1200 s
The discharge time is defined once and is valid for all steps. The
discharge time is a lockout time, which expires after switching off a
step. Until this time has not expired, the corresponding step for the
regulation is not available. The discharge time should be adapted to
the discharge unit of the capacitor.

If the automatic size-detection is disabled, then it is necessary to
enter the nominal step size. The input is done in var and is related to
nominal voltage. The adjustment must be done separately for each
output.
Warning: Before the step size is set, must be set the correct current
and voltage transformer ratio since the max. possible steps size is
limited by these ratios. After an step size has been entered, should
the current and voltage transformers ratio will not changed because
these changes affect the set step size. Hand-programmed "normal"
steps will be overwritten by the automatic step size detection

8 APPLICATIONS
8.1
Fan Control
The ESTAmat PFC-N is equipped by default with a temperature sensor. The fan is controlled
via one of the switching outputs.
Procedure:
•
Enable temperature alarm
In the expert menu item 512 set to "YES" (temperature alarm on).
•
Set temperature thresholds
Set the following items 513 (temperature threshold 1) and 514 (temperature threshold 2the
temperature thresholds. By exceeding the temperature threshold 1 is witched the fan
output. When you exceed the temperature threshold 2, all steps are switched off to prevent
overheating.
•
Select fan output
Select item 403 in expert menu and adjust for the step which shall work as the fan output
step type "AL".
Features:
In order to prevent hunting of the fan relay, the fan is turned off only at a temperature below
the set limit by at least 3°C. If the ESTAmat PFC-N is equipped with a temperature sensor,
the current cabinet temperature is displayed and the highest measured temperature is stored in
thi. Parallel to the temperature sensor can be connected a thermostat. By close of the
thermostat , the temperature limit 2 is activated.

8.2 Switching on target Pf 2 via digital input
By using a switch, the ESTAmat PFC-N will be switched to target Pf 2.
Solution:
Using the temperature input as digital input.
Procedure:
•
Enable digital input
Set item 510 in expert menu to "YES".
•
Using digital input as n/o or n/c
In the menu item 511 can be determined whether the digital inputs as n/c (NO) or n/o
(YES) is used.
Features:
The temperature input is used as a digital input, shows the controller at active input "high"
and with not active input "low" instead of the temperature. The controller uses with active
digital input the target Pf 2 and will show "NT" in the display.

8.3 Problems with the Step recognition.
The controller is used in a system with rapid changes in load conditions and has problems
with the automatic step recognition
Solution:
To solve this problem, the step sizes must be entered by hand, and the step recognition must
be turned off.
Procedure:
• Stop control.
Set item PFC to "OFF" in menu 100 (quick start menu).
•
switch off Step detection.
Set item 308 to "Yes" (step recognition off) in the expert menu.
•
enter step sizes.
Setting the nominal value of the capacitors connected at point 402 in the expert menu.
•
Check step type
For problems with the step detection, it may happen that the connected steps will be stored
by the controller incorrectly as "FIX-OFF". Therefore, the step type of each step should be
controlled under the menu item "403". All steps of the automatic control used, must be use
the step type "AUTO".
Features:
By switching off the automatic step recognition, a step failure or power loss is not reported.
To monitor the system anyway, it is appropriate to enable the control alarm to be alerted in
case of failure timely. (See alarm menu)

8.4 Transformer compensation
The compensation of a transformer can be solved with the ESTAmat PFC-N in two ways:
8.4.1 Setting a reactive power offset
Setting reactive power offset. This is added to the required compensation power within the
system.
Procedure:
Determine the required capacitive reactive power to compensate the transformer. Enter the
calculated value in the menu item "312". Control will start immediately with the additional
required reactive power.
Features:
The set here reactive power offset is always added to the measured reactive power. Therefore,
it's always the Pf appears before the transformer. This means that the system can capacitive,
but the measurement of the utility the required Pf recoded.
8.4.2 Mixed measurement:
By the current measurement on medium voltage side, is the from the transformer caused
reactive power measured and regulated by the connected compensation system.
20kV / 50Hz
Procedure:
Connect the measurement of the controller
as shown in the diagram adjacent. Then
start the automatic initialization. The
Transformer
Transformator
vector group ot the transformer is
automatically considered.

8.5 Reset defective steps respectively add aditional steps
If the controller has a step recognized as defective (3 switching operations without result), it
will be excluded for 24 hours from the regulation. After this period, the step is tested again
from the controller. If the controller can detect the step it will again be included in the control.
If not the step is blocked again for 24hours after 3 unsuccessful switching cycles. Defect steps
are in the "INFO" menu with the step type "flty" marked and flashing in the step indication.
When a compensation system need additional capacitors to be added, proceed as described
below:
Procedure:
Select item "403" in expert menu and use the
Confirm with f( ) button and use the
buttons to select the corresponding step.
buttons to adjust step type "AUTO".
Feature:
If a step because of power loss greater than 30% is exchanged, it's appropriate for the step, to
program the nominal step size by hand. Select in menu "402" the affected step and program
the nominal step size.
If the alarm was triggered by a defective contactor should, upon the exchange took place, the
accumulated switching operation under item "404" set to "0".
