CT connection test
There can be various reasons causing the controller goes to the standby state :
•
fundamental component of measuring voltage or current is below the instrument sensitivity
causing that power factor cannot be evaluated; this is indicated with the
U=0
or the
I=0
message in the control deviation flags area
•
no control section (output) available ( all of the sections have zero reactive power or are set
as fixed sections ); indicated with the
C=0
message in the control deviation flags area
•
control sections are forced off due to active actuation of any alarm; in such case the
alarm indicator flashes
•
the controller switched manually to standby state temporarily – the
standby indicator with
sinking time expiration level appears in such case
As soon as the events causing the standby state pass, standard power factor control process resumes
automatically.
4.4.2 Manual State
For testing purposes, especially during the first controller installation, you can switch the controller into
the manual state. Push the
button, then select the
icon and push the
button.
If any of outputs are on, question
Disconnect outputs ?
appears. If confirmed, the controller
disconnects all of outputs, otherwise actual state of the outputs stays unchanged. Then he controller
switches to the manual state.
The manual state is indicated with the
flashing indicator. No power factor control takes place,
state of the outputs stay unchanged. They are restored into this state even after a power failure. But
the outputs can be temporarily switched off due to any alarm actuation if appropriate event occurs.
During this state, you can manipulate with the outputs manually using the leftmost
button in
the same way as in the control state that is described in
the Multifunction
/
button
chapter above. When switching any of outputs on, the preset discharge time is respected, so the
output cannot be reswitched until its discharged time expires.
After the testing finished, switch the controller back into the control state using the same procedure as
when entering the manual state.
4.4.3 Automatic Output Recognition (AOR) Process
The controller can recognize types and sizes of compensation capacitors or chokes connected to its
outputs automatically using this process.
If the
AOR – Automatic Output Recognizer
parameter is set to
auto
, the controller launches this
process automatically if :
•
it is switched into the control state and is not in the standby state
•
none of the control compensation outputs is specified at a non-zero power (all of the control
outputs reactive powers are zero)
•
main PFC screen is displayed
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 PFC output
parameter group scroll to
Recognizer
and edit its
value to
Run
.
If any chokes are used in the compensation system, the Choke Control parameter must be
set first; otherwise, all of chokes (or any inductive character type outputs) will be recognized
as zero outputs.
