Also a sealing ring is part of the protection kit, which must be used when installing the control relay in switchgear cabinets and cubicles of protection class IP This means that there are deviations from the types of connection shown that do not restrict the control process.

Continuous monitoring for defective capacitor stages through self adjustment of control program Zero voltage and zero current fako with alarm signal.

It then behaves vrako the same way as in the initial start-up see section 3. If a floating potential contact is required, use an additional contactor relay. This connection variant can be chosen if the above-mentioned harmonics are sufficient for monitoring overcurrent or if overcurrent monitoring has been completely switched off setup code Press the “Select” key i.

Troubleshooting information is also provided there. The control relay creates frsko tolerance band or control band around its target in this case the target is to permit no reactive power.

Power factor control relay / panel-mount / programmable / digital – V | RM – FRAKO

Independent grako of capacitor switching time to match discharge time of capacitor stages. The switch outputs with the lowest capacity are assigned relative value 1. Check the control circuit according to the connection diagram and repeat the check system procedure Current paths for 21006 measuring devices should always be switched in series Introduce capacitors with smaller step size.

This signal does not activate an alarm. If alarm output was activated on frwko 6 of the RM device or contact 12 of the RM device setup codethis contact also closes. However, a capacitive power factor in this case is prefered to even small amounts of inductive reactive power. Messages A1 and A2 can be acknowledged by pressing any key or are automatically acknowledged after a waiting period of about 30 seconds.

The relative rrako for the bigger stages are calculated as follows: This results in a markedly increased life expectancy for the system. The control relay issues an alarm in the event of an error. Their innovative control characteristics meet all the requirements of modern industrial networks and make these control relays suitable for all applications.

This takes place in setup mode and simultaneously requires the manual programming of the stage parameters see section 4. The functions of the control relay are also described in brief in section 1.

Target power factor 1. Single phase connection 2. After connection it is necessary to remove the short-circuit jumper on the current transformer, if present. From the front panel using a screwdriver Front panel dimensions: The flashing LED in the stage indicator a shows which switching output is presently selected.

For a target power factor of 1. This setting is to be selected if the low voltage network is fed by several transformers switched in parallel. Switch outputs at which little or no capacitor rating has been recognised are assigned switching sequence factor 0.

The type of connection shown above should be used if the voltage between the phase conductors does not exceed VAC. Likewise this message can only be acknowledged by eliminating the error.

Reactive Power Control Relay RM 2106/12

Their high accuracy and sensitivity even in networks heavily polluted with harmonics make them suitable for power generation installations and installations which 206 continuous or sporadic feed-in to the supply network.

Fault in capacitor stages.

Notes on troubleshooting 28 Necessary action Check that operating voltage applied to the control relay is at the right level. This means that all frequencies up to the 31st harmonic are taken into account calculating harmonic overcurrent in the capacitor see also section 4.

All information on FRAKO

This results in a markedly increased life expectancy for the system. Stage rating Relative value 6. Setup code Significance Target power factor Maximum harmonic overcurrent until the alarm is activated -Alarm output on contact 6 and contact 12 respectively -switch on or off alarm E5 Automatic determination of response current Manual setting of response current Relative value of the stage Service: After a waiting period of about 10 seconds the switching status of the selected switch output is inverted.

This requires that automatic connection identification should be activated. The control voltage of the transformer may not exceed VAC. The electrical connection is created by means of plug-in connectors which are also included in the delivery.

2160 automaticresponse current identification is 23 Note: The control relay delay time is adapted to the size of the deviation.
