In order to keep the load on the current transformer as low as possible the supply lines should have a cross-section area of 2. OFF” will appear on the display until the control relay has switched off the first stage after approx.

High load change; The delay time was set too low. If this cannot be achieved the voltage must be earthed, even if it is only small protective voltage. Fixed stages are stages which are not included in the normal control cycle but are switched on immediately after the control relay is switched on and always remain switched on.

Check if capacitors are energized after switching. This takes place in set mode and at the same time it is necessary to programme the connection and stage parameters manually see section 5.


Target power factor setting adjustable from 0. The response current corresponds to half the width of the tolerance band, within which the reactive current can change without capacitor stages being switched on or off.

In such situations we recommend that the stage identification be switched off and the relevant values be programmed manually. These values determine the stage sequence. When setting “OFF” the alarm is suppressed.

Should the control relay fail to identify the current and voltage source due to power instabilities, repeat the procedure when the power has stabilized. Consumption in Current Path: How to programme the Control Relay: Refer to section 2. The installation and connection of the RM is only finished, once it has been installed and wired according to these instructions. Find more suppliers in Chennai Power Controllers in Frko. By pressing the “-” button several times the stages 5 – 1 will appear on the display in a descending sequence.

Measure the current of each capacitor stage with a clamp-on current meter. During the “set mode” none of the capacitor stages is changed and there is no switching of the alarm contact. See also section 5. Unstable power supply power factor fluctuation. The 6906 Relay RM allows the first three control outputs to be treated as fixed stages. By pressing the “Set” button the display shows the maximum value of the factor by which the RMS current has exceeded the nominal current.

After this period the values can only be read read-only mode. An effective supervision of the reactive power control system capacitor bank is secured by the power factor display. Four-quadrant power control with LED display when active power is generated into gm.


If the RM does not act as described above, remove voltage source and check installation.

Before a reactive power control system can be put into operation, the target power factor has to be programmed. It has to be passed by both capacitor and consumer current. Page Page Summary of Instructions It is assumed that the connected capacitorstages are sufficiently dimensioned. This setting has the following effects: Get best deals for coconut. The procedure for checking or reprogramming the set values is as follows: Press the “Harm” button to exit the display. On pages 15 – 17 all other preprogrammed standard values and their programme ranges are listed.

Foil keyboard with 4 buttons Design: In order for the relay to be able to determine the mode of connection at least one capacitor stage must be operational.

The stage currents ascertained are then stored. Check the control circuit according fraok the circuit diagram and repeat the automatic test procedure. Automatic Power Factor Panel.
