GENERAL INFORMATION


Assembly and connection

The regulator can be embedded. The cut-out to be made in the mount (max. thickness: 10 mm) is 138 x 138 mm. The screws supplied with the regulator must be used to maintain the class II protection.

Current transformer connection: to ensure the load to the current transformer's secondary is as low as possible, the cables must have a minimum cross-section of 2.5 mm². The measured current should not exceed 5A.

Voltage measurement connection: it is possible to sepa-rate the feed voltage from the measurement voltage (for example for readings on the HVA/HVB network). In all cases, it is important to protect this input with an external fuse.

Alarm switch: a dry contact for alarm activation is avai-lable on the a/b alarm terminals. The switch closes if there is no voltage or an alarm is present on the regu-lator. If an alarm is activated, an indicator LED will light up on the front panel ("alarm" LED) and the correspon-ding fault will flash on the regulator's display. The alarm switch can withstand 3A at 250 VAC.Control contacts: Terminals "PI" and "PII" allow connec-tion to the control voltage of the switches. These

contacts are easily assimilated with dry contacts.In order to avoid overloading control contacts, the sum of the currents to hold the switch coils in the closed position must not exceed a maximum value of 5 A. The control voltages must not exceed 380 VAC.

Tariff change: The regulator can observe a second operating mode by means of a second external dry contact. (See Tariff 2, Table 1). The connection is made on the terminals with cos phi 1/2.

GENERAL INFORMATION



Quick commissioning step

1) Ensure the regulator is correctly connected.

2) Power up the regulator. The regulator will launch the automatic recognition procedure. This procedure will last between 2 and 15 minutes. At the end of this procedure the value displayed will correspond to the cos phi of the installation. At this stage regulation is effective (cos phi setpoint 0.96).

3) Modification of the cos phi setpoint (if required) and configuring to display the actual current.• Press the prog. button for 8 seconds, " -1- " will appear and the "manual" LED will flash.• Press prog., the cos phi setpoint value will be displayed. To change the value press "+" or "-".• Press the prog. button. The value "-2-" is displayed. Press "+" until the parameter 18 is reached (the display shows "18").•Press prog. The winding ratio is displayed. To change this value press "+" or "-". • Press prog. Press "=" until "end" is reached. Confirm by pressing prog. If other modification of the regulator's settings are required, refer to the detailed settings (page 10).

Table 1: Regulator parameters

The settings can be modified to allow several operating modes. The regulator is supplied in a standard factory configuration.To avoid any programming errors, the parameters cannot be set in the first 5 minutes the regulator is powered on. Once the modifications are made, other modifications can be made after an hour. After this time has elapsed the parameters can be viewed. In order to modify the parameters again, the regulator feed must be disconnected temporarily.

To program and/or see the parameters, proceed as follows:• Press the "Prog." button for at least 8 seconds.

The display will show "-1-". This figure shows the parameter number to be selected (see Table 1).

• By pressing the "Prog." button again, the display will

show the current value. • By pressing buttons "+" or "-" a new value can be

entered.• By pressing the "Prog." button again the following

parameters can be accessed.• Pressing the "+" button after viewing the parameter

"-29-" or pressing the "-" button after viewing the parameter "-1-" will result in "End" appearing on the display.

• Confirm exiting the parameter setting mode by pressing the "Prog." button when "End" is displayed. The regulator will launch its program with the values entered.

POSITIONING



Displays

The selection of displayed values is totally independent from the regulator operation. A diode to the right of the "cos j", "A", "Harm" display indicates which variable is being displayed. The display is able to display the following variables (by pressing the corresponding buttons(s)):- The power factor is the default value displayed- Button "Q" displays reactive current- Button "P" displays active current- Pressing buttons "P" and "Q" together displays the apparent current- The "Harm" button will display the harmonics from

rows 5, 7, 11 and 13. Buttons "+" and "-" are used to scroll through the value of the different harmonics. (When the display shows 5. 2.9 this indicates that the harmonic of row 5 has an amplitude of 2.9%)- A 3 second press of the button "aut/manu" will allow manual implementation of the stages. Buttons "+" and "-" are used to scroll through the stages. After a delay of about 12 seconds, the stage will change to the opposite state to its original state. During switching, the number of activations is briefly displayed (0.350 indicates 350 activations).
