NOVAR 2600 Operating Manual
If the CT-ratio is not set (or its value is 5/5 A or 1/1 A), call for the CT-ratio setting appears
before the AOR- process is launched. When this call is ignored and the CT-ratio is not set
properly the power values of outputs recognized during the AOR-process will be incorrect.
As soon as the process is initiated, the information message appears in the main PFC screen :
Fig. 4.14 : AOR Start Message
During following 10 seconds, you can either cancel the start command with the

button or to skip the
message timeout with the  button to start the AOR process immediately. Or you can simply let the
timeout to expire and then the AOR process starts.
First of all, all of control outputs (i.e. excluding the fixed ones and optional alarm/fan/heating ones )
are disconnected, step by step. Actual state of the outputs can be watched on left part of the screen :
• … disconnected output, fully discharged, unknown (or zero) type
•
… disconnected output, not fully discharged
• … connected output
Then the instrument waits until discharge time of the outputs just disconnected expires - such
undischarged outputs can be identified with decreasing shadow filling. 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 outputs step by step. After each
of the step is switched off, its type and size is displayed for short time. From the example above you
can find :
•
the output No. 2.1 that was just measured was recognized as three-phase capacitor with total
(ΣL) reactive (nominal) power of 19.9 kvars
•
individual phase powers of the capacitor are 6.36/6.53/6.98 kvars
•
the output No. 2.2 is just being tested (switched on)
• up till now, outputs No. 1.1, 1.2, 1.4, 1.7, 1.8. 1.9 and 2.1 have been recognized as three-
phase capacitors
•
outputs No. 1.3, 1.5 and 2.2 ÷ 2.7 have been recognized as “zero outputs” (with no reactive
power response)
