Technical Data At the same time, the alarm contact closes and the “Alarm” LED lights up for as long as there is no voltage applied to the measurement input terminals of the control relay.

Values between 1 and can be entered eg. During the “set mode” none of the capacitor stages is changed and there is no switching of the alarm contact. The conditions for an alarm can be 9066 in section 6. Fault in control circuit contactors do not switch Fuses of the capacitor stages are defective or missing.

The relay’s cyclic operations prolong the life of all connected devices by averaging the length of time the capacitor stages are switched on. By pressing the “Set” button again the display shows the actual power factor and the alarm marker “Ampere” no longer flashes.

If S1 k frao S2 l are connected r, wrong way around gm the CT is installed in wrong direction, connection mode number must be added by 6. No cyclic switching; the stages within each level are switched on.


However, we recommend that if capacitor stages are added at a later date, the set-up procedure be repeated see section 2. Check if capacitors are energized after switching.

How to programme the Control Relay: It is not allowed to use both connecting terminals “V” and “V” rmm. Furthermore a sealing ring is supplied, which must be used when installing the control relay in switchgear gm and cubicles of protection class IP If this, however, is not possible due to lack of capacitor stages available, an alarm is signalised after several minutes depending on the size of the difference. Important, read before commissioning!!!

Active and reactive currents are measured seprarately. The alarm markers remain active after the alarm until they are acknowledged by pressing the “Set” button.

Faults 1 2 3 4 5 6 7 Possible Causes Necessary Action Control relay does frrako function, digital display remains blank. In order for the relay to be able to determine the mode of connection at least one capacitor stage must be operational. Check if the position of current transformer corresponds to the circuit diagram. This setting has the following effects: From this mode of display the compensation effect of the capacitor stages e.

By setting “all” all counts are reset. In order to permit the widest possible use of the control relay, multiple settings are available. Crako this period the values can only be read read-only mode. Before a reactive power control system can be put into operation, the target power factor has to be programmed. Suitable for current transformers with rated secondary current of 1A or 5A.

Fault in capacitor circuit.

Control circuit is not connected properly or there is no control voltage There is no neutral on the contactors. The maximum load for the alarm contact is VAC and 3 Amps. Fault in control circuit. Circuits October 6906, Lab Call Send a quick message. See also section 5. View Contact Call Seller Now.


Possibly the control relay has already been used before and acts as described in section 4. That means for example: When the apparent current falls below frak.

The result corresponds to the connection mode number which have to be entered. Foil keyboard with 4 buttons Design: The rmm relay now identifies the location of the current and voltage source. If the result is higher than 11, 12 must be subtracted. The current flowing on the secondary side of the CT is too small. If a capacitor stage is added later on, or defective fuses are exchanged, the RM itself identifies this after some time and the stage is then reintegrated into the normal operation.

All information on FRAKO

Before commissioning of the control relay it has to be ascertained that it is not possible to touch the connecting terminals e. Nature of Business Manufacturer. If the RM does not act as described above, remove voltage source and check installation.

All measuring instruments in current path must be connected in series Finer adjustment of the capacitor stages is required. Press the “Harm” button to exit the display. The LED “alarm” lights up for as long as a state of alarm exists.
