The following Figure 10 shows the characteristics of the control band when set for a capacitive target power factor. ON” appears on the display until the control relay has switched on the 6th stage after approx. Current transformer is in the wrong place.
FRAKO RM9606 Reactive Power Control Relay
The terminals for V and V are internally bridged. The power factor display is independent frakl the control relay operation and can be reprogrammed at any time. If this ratio is exceeded by the factor set for at least one minute due to harmonics and the resulting resonance phenomenon, the control relay switches off all stages which have been switched on.
If no voltage transformer is present, the value “1” must be entered. Programmable overcurrent alarm threshold limit from1. Current transformer is defective. The discharge time can be set between 5 and seconds.
The “Harmonic” LED flashes until the alarm is switched off. ON” appears on the display until the control relay has switched on the first stage after approx.
The control relay is in the read-only mode if above is not possible. The relay’s cyclic operations prolong the life of all connected devices by averaging the length of time the capacitor stages are switched on. Year of Establishment By shifting the band into the capacitive range see Figure 7 in section 5. Check the control circuit according to the circuit diagram and repeat the automatic test procedure.
By pressing the “Set” button again the display shows the actual power factor and the alarm marker “Ampere” no longer flashes. The target power factor is now stored permanently. How to put out the alarm is explained in section 5. By pressing the “-” button once “6. Also programme modes 7 switching sequence and 8 number of contactors used have to be entered manually.
Power factor control relay / panel-mount / programmable / digital – RM – FRAKO
The outputs S1 and S2 of the current transformer are connected to the terminals S1 and S2 of the control relay. Get best deals for coconut. If the RM does not act as described above, remove voltage source and check installation. In this case the LED “Regeneration” lights up. Check the fuses and contacts of the capacitor contactors and perhaps current absorbtion.

Check the current transformer. After connection the short-circuiting bridge might have to be removed from the current transformer. During the “set mode” none of the capacitor stages is changed and there is no switching of the alarm contact. The mode of operation of this adjustment can be seen in Figure 4 and Figure 5. The control relay consistently achieves this control band by switching on and off systematically. The set discharge period is maintained.
By pressing the “-” button several times the stages frakoo – 1 will appear on the display in a descending sequence.
This process can take up to 15 minutes. After current is restored the control relay switches the required stages on. It is also possible to programme the phasing manually see sections 5.
By pressing the “Set” button several times the display shows the order and the maximum values of the exceeded harmonics starting 906 the maximum deviation. Check if capacitors are energized after switching.
Functions The reactive power and active power portions of the fraio source are continuously calculated in the control relay from the measured voltage and the signals of the current transformer.
