Table 44 (Continuation): Code of Plug&Play errors�
Code Description
P03
Unstable measurement. Load changes during the process.
P04
Error in the measurement of the largest capacitor.
P05
No capacitors found.
P06
Incorrect measurement of the number of capacitors.
P07
Incorrect measurement of the ratio of the first capacitor.
P08
Possible error in the program calculated.
P09
C/K out of range.
In the case of the
P00
error, i.e., when capacitors have been deactivated by a leakage current alarm
or forced in the On/Off/Auto Configuration, the P&P function will not be started until the problem is
resolved.
The Plug&Play function is designed to assist with the installation of the reactive energy compensation
system, with the initial configuration of the regulator or when there are changes in the system (new
regulator, new cabling, new stage, etc.). For this reason, it is necessary prior to the Plug&Play function
to solve the possible problems with faulty capacitors by means of maintenance or replacement, as well
as to configure all the stages in Auto mode, as they come by default.
Conditions for the correct operation of the Plug&Play function:

The system should be maintained with an inductive cosine of 0.62 to 0.99
throughout the process.

The power in the system should be stable. Any major load changes (>10 % in less
than 20 seconds) would result in an incorrect calculation of the capacitor power ratings.

There must be enough current in the system, above 100 mA AC at the regulator
intake.

If the load is unbalanced, the correct operation of the Plug&Play function will depend
on the phase to which the current transformer is connected.
Once the Plug&Play function is finished, the primary of the current transformer needs
to be configured in order for the unit to measure the current and the powers correctly.

If no keys are pressed for 5 minutes, the unit switches to the simulation screen,
“5.30.- SIMULATION
