FRAKO RM9606 Reactive Power Control Relay
It is assumed that the connected capacitorstages are sufficiently dimensioned. Relay does not respond to manual operation although it has voltage and digital display is operational. By setting “all” all counts are reset. The procedure for checking or reprogramming the set values is as follows: This number corresponds to the first variable which is displayed or can be changed in the following sequence see Table 1. Excellent after sales service and track record of consistent performance levels vrako BARON as a Leader in their line of activities.
The rated current in the current transformer path should not exceed 5 Amps. Power Factor Correction Panel. The mode of operation of this adjustment can be seen in Figure 4 and Figure 5. Get Best Price Request a quote.

Should the control relay fail to identify the current and voltage source due to power instabilities, repeat the procedure when the power has stabilized. For voltages greater or equal to V, a control transformer for the supply of the controller must be used. In the case of the correct operating voltage, the contact closes if there is an alarm.
Target power factor setting adjustable from 0. Before a reactive power control system can be put into operation, the target power factor has to be programmed. The stage currents ascertained are then stored.
Check the control circuit according to the circuit diagram and check fuses.
During the identification process all the control contacts of the relay are mr switched on and off again. As already described the control relay tries to reach its programmed control band.
In order to reach the set mode again after this period, it is necessary to disconnect the control relay from its source for a short period of time.
In order to maintain the function of the undervoltage monitoring it is absolutely necessary to make sure that the control voltage of the contactors is in the same phase as the control relay supply.
As a protection against unintentional reprogramming, the set mode programming mode can be invoked only within 5 minutes after operating voltage is applied.

When the optional switching combinations are sorted according to their capacity, the capacity difference between two successive combinations may only be 1. Control circuit is not connected properly or there is no control voltage There is no neutral on the contactors.
If more stages are required the switching time delay is shortened depending on the number of stages required. The pre-mounted terminal connections allow a quick and easy installation. The order and the maximum value of the harmonics which have been exceeded, beginning with the maximum deviation, are displayed by multiple pressing of the “Set” button. After connection the short-circuiting bridge might have to be removed from the current transformer. See section 8, page 35 4.

Consumption in Current Path: During installation and service work the control relay must be kept free of voltage. The RM checks stored stage currents at specific time intervals during normal operation.
At the same time an alarm is signalised.
To reach the set mode again, the control relay must be disconnected from its source for a short period of time. In order not to overload the control contacts the sum of the holding currents of all contactor coils connected may not exceed a value of 5 Amps. Page Page Summary of Instructions
