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

Operation of ESTAmat PFC-N
in High Voltage compensation panels
The below list is showing the parameters of the ESTAmat PFC-N which
need special attention for operation in High Voltage compensation
panels.
Attention: When putting the ESTAmat PFC-N in operation, the
countdown for “AI” has to be stopped by pushing the “esc”
button.
Un = Adjust the nominal voltage to local conditions
Ct = Adjust the Ct ratio to local conditions
Pt = Adust the Pt ratio to local conditions
St = Adjust the switching time to local requirements
208 = Set item 208 to “No” and switch off the countdown for “AI”
308 = Set item 308 to “Yes” and switch off the automatic step size
detection.
401 = Adjust discharging time to local conditions
402 = Adjust step sizes
Attention: When resetting the ESTAmat PFC-N by using menu
item 601 or 602, all adjusted values are set to factory settings.
When using factory settings for High voltage compensation
a proper and save operation is not possible!

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 (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 () 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

3 DISPLAY
In case of an alarm will flash alternately at ESTAmat PFC-N with "ALARM" an error code in the
display. The table below gives an overview of all possible error codes.
To reset pending alarms hold the (esc) button pressed for 5 seconds.
measured voltage is outside the set tolerance
measured current is less than 15mA (check the short
circuit bridge K and L and the entire current path
measured current is to high
The controller cannot achieve the target PF
The set limit for the THD of the voltage is exceeded
/
One or more steps are broken. The defective step is
blinking with the alarm message.
/
One or more step's have fallen below 70% of initial
power. step number and error code will flash alternately.
For devices with software version before 1.04 the alarm is
triggered at 50% of initial power.
The second temperature limit is exceeded. Stage were
switched off successively.
Set limit of operation hours has been exceeded
/
Set limit of the max. allowable operation cycles, for one
or more steps, has been exceeded.

4.2 Info (Step database)
In the "INFO" menu for each connected step the number of switching cycles, the current step
size and the step size in relation to the initial step size is stored.
Using these data, conclusions can be drawn on the condition of the site and the condition of
single step's. Step sizes are only shown in kVar when in the "Setup" menu the CT ratio is
set.
