NOVAR 2600 Operating Manual
4.4.5.2.3 ACD Process – Automatic Connection Detection
The type of connection must be set always manually.
The U1 angle can be set manually too, but we strongly recommend to use automatic setup – the ACD
process (Automatic Connection Detection). This process not onlz detects and sets the U1 angle, but
network nominal votage U
NOM
as well.
For the ACD process usage following condition must be fulfilled : either
three-phase
or
single-phase
compensation
capacitors
are connected to
the first four control outputs
. If,
for example, two-phase capacitors or any chokes connected to the outputs, the CT test gets
fail results !
If inappropriate compensation elements connected to the first four outputs,you can set such
outputs temporary to
the fixed-off
control state; then the instrument will use tor the ACD
process the next four outputs that are set as the control outputs.
Following conditions must be fulfilled for the ACD process launch :
•
connection type is set to 1Y3 or 1D3
• U1 angle is not defined (---)
• switching mode is not set to linear
• main PFC screen is displayed
The controller launches this process automatically after powerup (if it is not in the standby state due to
any of alarms).
The process can be started manually too. You can launch it not only in the control state but in the
manual state as well. For this, in
the Installation parameter group scroll to the U1 angle and set it as
undefined (---).
As soon as the process is initiated, the information message appears in the main PFC screen :
Fig. 4.22 : ACD Start Message
During following 10 seconds, you can either cancel the process launch with the  button or to skip the
message timeout with the  button to start the ACD process immediately. Or you can simply let the
timeout to expire and then the ACD process starts.
First of all, the first four control outputs are disconnected, step by step. Then the instrument waits until
discharge time of the outputs just disconnected expires. During this, Output 1.1 message flashes in
the headline, that means that the instrument waits till output No. 1.1 is ready to use.
After all of the outputs discharged, the instrument starts to switch the four outputs step by step. After
each of the step is switched off, following information appears :
• U1 angle found (0-L1, for example)
• U1 voltage (234 V)
• in the bottom reactive and active powers of the outputpři typu zapojení 1D3 power found and
corresponding angle between voltage and current phasors
