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
