Configurations
11.3 - Ratio of external current transformer
In the
C03
parameter you can change the ratio of external current transformer (CT). The minimum value is 5:5 (without an external CT), and
the maximum is 3000:5 (i.e., when 3000 Amps pass through the cabling, there will be 5 amps at the output of the CT).
Care should be taken when setting this value, since all the calculations and electrical information that the device offers are
dependent on this.
11.4 - Activating the alarm
The
C04
and
C05
parameters allow the outputs 31 and 32 to be configured for alarms of Power Factor and Demand, respectively. The choice
between them is independent, and if you configure "NO", the output can be used to control power factor, demand control, or if nothing is
allocated to any of these controls it will be an "events scheduler”.
The Alarms take precedence over the scheduled event outputs, i.e., if outputs 31 and 32 are allocated to the schedule, and alarm 1 and/or 2
become activated, the output no longer functions as a schedule, it becomes an alarm function.
Operation: When an alarm occurs, the output 31 will be triggered intermittently (on and off every second), if it is a PF, or the output 32, if the
event is to control demand. The alarms are deactivated by pressing the button, returning again when an error occurs again.

Setting up the initial screen
When setting up the
C06
, you will be informing the device which screen to show after being idle for 15 seconds, if you are in the menus
"configuration parameters," , "visualization of maximums and minimums" or "quick access" or for 2 minutes, if you are in the " visualization of
electrical parameters." For example, if the configuration of the "initial screen" is set at "current" (CORR) and the unit has been idle for 15
seconds in somewhere in the "configuration parameters" menu, the display screen will automatically return to where you are for the "quick
view of electrical parameters," showing the currents.
11.6 - Backlight e Contrast
In the
C07
parameter the device display backlight can be adjusted. The backlight is the brightness of the screen, and can choose between
Maximum, High, Medium, Low and MINIMUM.
In the
C08
parameter it is possible to configure the display contrast, which will adjust the brightness of the letters that are shown.
MENU
10 - SETTING THE CLOCK AND DATE
On the
R01
,
R02
e
R03
parameters of the menu, you can set the time, date and day of week, respectively.
The time setting is done by increasing, or decreasing minutes, which consequently will also set the time.
Seconds are not adjusted, but when the time setting is confirmed, they are zeroed.
The date is adjusted by the increasing or decreasing the days, which will consequently change the month (the months change after the 31st day)
and year (the year changes after the 12th month). The internal clock has a calendar set for leap years, and the number of days in any month, and it
will progressively show the date correctly. However, when editing the date, it is possible to insert an invalid value, such as February 31.
The User
should take all precautions to avoid this.
The day of the week is chosen by selecting from Sunday to Saturday.
11.1 - Language
In the
C01
parameter, you can select the device menu language. The options are - Portuguese, English and Spanish.
11.2 - Serial Communication Address
In the
C02
parameter it is possible to change the address of the RS485 serial communication. The number must be unique in the network, and
at most 247.
12.1 - Reset Power
The active, reactive and apparent single-phase and three-phase power are tabulated over time and are periodically stored in an E2PROM
memory so that this information is not lost in the case of having to reboot the machine for some reason, or if there is a power outage and the
device is powered down. When performing this function, all power is zeroed.
12.2 - Clear Names
The use of this feature causes all the names assigned to demand control outputs to be erased.
12.3 - Clear Memory
This function causes all the data logger memory to be erased.
12.4 - Display Outputs
DThis may become a little confused in relation to which outputs control the power factor, which ones are for the demand control, which are to
schedule events, and which ones are for the alarms, this feature helps to make this a little clearer, since it indicates, through a display screen
and LEDs, that shows which outputs belong to each function.
12.5 - Check order of the phases
This function must be performed after the installation of the device to make sure that it is correctly installed. If it is correct, an "OK" will be
displayed, however, if not, there will be an error warning, and the unit will indicate the phases with these errors.
Because many electrical installations do not have all phases shown, this function becomes necessary.
If the unit shows an error, check the following, in this order:
- Is the current in each phase greater than the "external CT ratio," divided by 20? For example, if the external CT ratio is 500:5, then the
current must be greater than 5 Amps (500/5 = 100, 100/20 = 5).
- Try to invert the polarity of the current measurement of the phases that are showing errors. If only one phase is showing an error, it is
quite possible that the current polarity is inverted (the effect of the inverted polarity is an indication of capacitive power factor, when it is
inductive, and vice versa).
If the error continues, and for more than one phase, the voltages and currents may not be connected correctly (voltage 1 with current 1,
and this applies for phases 2 and 3). One may observe the active, reactive and apparent power, so that the consistency of readings may
be observed. If the reading of two of the phases is inconsistent, you should try to change their current signals, namely, the current in-CT2-
IN and CT2-OUT, should go to CT3-IN and CT3-OUT, and the current in 3 goes to 2.
- If the function is showing an error but no phase is shown (all phases are zero, in the display, in the result of the function), then the error is
in the voltage phase sequence. Therefore the order of phases should be reversed, B with C, A with B or C with A, for the controller to
sample some of the sequences: ABC, BCA or CAB.
Note: This function works perfectly for inductive circuits. If they are capacitive, it may show unjustified errors, or not display the errors
correctly.
13 - OTHER IMPORTANT INFORMATION
* The voltages as well as the current have a minimum value to be measured, so that the controller shows the information correctly. If any of the
three voltages is below 50 volts (but greater than 10), the controller will show the value of 0.1 volts, and indicate "voltage limit error" in the
corresponding phase. If any current is less than 10mA times the CT ratio, then the current and the powers of this phase will be shown as a zero
value. For example, for a CT of 500:5, the minimum current would be 1 Amp (500/ 5*10mA).
* The accuracy of the instantaneous measurement of the electrical parameters is 2%. However, for power, this is 3%. These errors do not take into
account the accuracy of the external current transformer, which is the responsibility of the equipment user. It is advisable to use Class 0.3
transformers.
* When a measured value exceeds one million, the unit changes from Kilo (k) to Mega (M) and when this passes one billion, it will be shown in Giga
(G).
* The equipment considers, for measurements and calculations, up to the 5th harmonic for voltage and the 233rd for current.
* If the equipment loses it calibration because of some external noise, it will automatically reload the values stored in the E2PROM, and a warning
will show: "
Recar. Calib.
"
14 - TROUBLE SHOOTING
- Capacitive power factor, should be inductive - Polarity of the current sensor (CT) reversed.
Action: exchange TCx IN with TCx OUT.
- Currents and power factors show very abrupt changes - This effect is common in industrial installations, where there are machines that
have large motors or are controlled by semi-conductor power devices.
- Currents and power are zeroed - The current is probably below the minimum threshold for reading.
- Voltages are zeroed, or at 0.1 volt - Voltage at zero is indicative that the voltage is below 10 volts. If at 0.1, this is indicative that it is
between 50 and 10 volts.
