RN-15 voltage relay has fixed settings and does not need programming.
RMM2 Maximum and minimum voltage relay for single-phase lines.
Protected devices are connected to the output socket of the voltage relay.
Connect the voltage relay to a~220- 230 V/ 50 Hz socket to set protection parameters.
The 1 st one is used to switch on/off voltage relays on the position.
The voltage relay will be in this mode as long as the supply voltage attains a value within 204-244 V± 2% range.
Controlling local devices such as separating transformers(CT/VT) and voltage relays.
Ambient temperature during the voltage relay operation must be in the range +10 to +35 С.
In this case, the contacts of the coil induces a voltage many times(even several times)in excess of the nominal voltage relay ON.
Maintaining the critical voltage relays to be switched on regardless of the voltage drop.
The relay module makes it possible to control high current consumption electrical devices(R1 and R2 relays up to 4 A; R3 and R4 up to 8 A),supplied with either direct or alternating voltage(relays R1 and R2 up to 48 V AC/DC; R3 and R4 up to 400 V AC/ 250 V DC).
The set parameters will be saved in the voltage relay nonvolatile memory in 5 seconds after the last button press.
The voltage relay is in normal operation, when the active voltage of the power supply network is within 199-252 V limit and the turn-on delay time is over.
When the protection actuation parameters of the voltage relay have been set, connect protected equipment to its socket.
The voltage relay is in the normal operation mode, when the active power supply voltage is within the range of voltage actuacion protection thresholds having been set by a user and the turn-on delay time is over.
Electrical connection to the system eHouse requires a separate voltage relays and connecting external high-power devices.
Before connecting equipment to the voltage relay it is necessary to set actuation values, namely, high voltage switching off threshold(UH), low voltage switching off threshold(UL) and turn-on delay time after voltage normalization of the power supply network(td) see p. 7.
Then there will be the"deF_H245_ L175_d180" creeping line on the display a and the voltage relay enters the operation mode with the following parameter values.
Other protective equipment includes the voltage relay(which trips if the voltage in the high-voltage circuit falls below 2400 V), the dynamotor/compressor overload relay, the heating circuit overload relay, and the automatic control shutoff switch.
