5.4 - Parameters Configurations
This menu is subdivided into eight sub-menus for the configuration of all the controllers' parameters. To access: being in the "Quick
View of Electrical Parameters" menu, press the and keys at the same time.
Note: To configure parameters, whenever entering this menu, you must first enter the code "123", in menu 1 (Access Code).
After insert the code, you must wait until shows the message "
Right Code
" or “
Wrong Code
", then browser through other menus.

5.6 - Error Codes
Whenever an error is recognized by the controller, a message will be displayed, appearing alternately with the menu that is being
displayed.
The eight errors that can occur, which are described in Table 1, are shown by the controller as numbers, as the following example
shows:
In the example, the controller is indicating that 1,2,3,7 and 8 are in error status. 4,5 and 6 are NOT in error status, and therefore in
place of the numbers there is a "-". But, if instead of this symbol there was a number, it would indicate an error. Likewise, if instead of
the 8 there was a "-", item 8 would not be in error status.

6 - POWER FACTOR (PF)
The power factor is the relationship between active power and apparent power of an electrical system. In addition, as the harmonics
influence the value of these powers, they should be considered in the calculations. This device takes into account the harmonics.
The control of the power factor is achieved by inserting and removing capacitor banks in parallel with the electrical grid.
In general, when motors are turned on, the power factor tends to be lower for the inductive side; because of this, capacitors should be
placed in parallel. When the motors are turned off, the power factor tends to be less inductive and if the capacitor banks are activated, this
may be capacitive.
Table 1: Error codes
6.1 - Configurations for the control of the power factor
6.1.1 - Outputs
The User can select the number of outputs for the power factor control; this can be between 0 and 32 (none or all outputs). This parameter can
be edited in menu “
N
The outputs for the control of the power factor always start at the first output, i.e., "OUT-01" will always be the first output for this control. The
other outputs are next, in ascending order.
Note:
To change the number of outputs for the Power Factor or Demand control, the controls must be disabled. If not, you cannot change the
alteration. CAUTION, any output that is activated will be deactivated. In other words, all outputs will be reset.
6.1.2 - Reference values for the control
In the “
Min Pow Fac
”
menu the value of the minimum desired power factor, can be edited, this is the reference value where the power factor is
low; the capacitor banks may be inserted. In the menu “
M
”
, the maximum power factor value desired can be edited, which is the
reference value when the power factor is too high, the capacitor banks may be removed.
6.1.3 - Information on reactive power of the installed capacitor banks
To control the power factor, the controller needs to know the capacitive reactive power (kVAr) of each capacitor bank installed on each output.
This helps the controller to insert or remove the right amount of capacitors to correct the power factor.
The value can be edited in the sub-menu “
React Cap Pow
”, and the values are in VAr (Volt Ampere Reactive). Therefore, if the informed
value is 1kVAr, for example, you should enter the value 1000.
If no reactive power value is associated with an output (i.e. it is at zero), this output will not be used to control the power factor.
6.1.4 - Enabling the power factor control
Control of the power factor can be enabled or disabled in menu “
Activate ctrl PF
”, by selecting "YES" to activate the control, and "NO" to
disable it. When activated, the control operates every 30 seconds, and can activate or deactivate more than one capacitor bank at a time.

7 - DEMAND
Demand: average of the active or reactive electrical power, requested for the installed electrical system by the installed load operating in the
consumers unit, during a specified time interval.
Annexed to this manual are some case examples..
For finer control, the
PWR-3200 plus
works by disconnecting and reconnecting loads (when necessary) every 30 seconds.
