If any ust inside the device cover or case is found, remove it carefully with compressed air. For information about the maintenance of REC 523, refer to Chapter 8. Service. Remote control units are measuring instruments and should be handled with care and protected against moisture and mechanical stress, especially during transport.
Measurement functions are available, for example, for three-phase currents, neutral current, three-phase voltages, residual voltage, frequency, and active and reactive power. One REC 523 device can be used to measure 2 feeders or branches by means of 9 analogue channels.
Technical Reference Manual 5.1.2. Protection and fault indication functions REC 523 provides a set of protection functions which also can be used for fault indication. Before taking a protection function block into use, ensure that the function block operates correctly by checking the default values and by properly setting the parameter values.

The remote communication protocols IEC 60870-5-101, Modbus (RTU and ASCII) and DNP 3.0 are available for REC 523. The REC 523 includes SPA slave and LON serial communication protocols. In a customer-specific configuration, special events can be generated via an EVENT230 event function.
Power backup for the station can be arranged by connecting 24 V (2 x 12 V) sealed lead acid batteries to the REC 523 device. The batteries supply the REC 523 device and the communication device during a mains failure. Thus the communication between the device and a network control centre operates in any situation.

(ACFail, active low). The indication of a low auxiliary voltage (ACFail) is available in REC configuration environment and can be connected to any signal output of the REC 523 device. The auxiliary voltage indication in the REC configuration is as follows: •...
In addition to conventional matching transformers, current sensors and voltage dividers developed by ABB can be used. Depending on the hardware equipment, REC 523 has 9 sensor inputs. A current sensor (Rogowski coil) or a voltage divider can be used with the REC 523 device.
5.3.2. Technical data of measuring devices When the REC 523 device is configured, the technical data of the measuring devices is set in separate dialogue boxes in the Relay Configuration Tool. The set values affect the measurements carried out by the REC 523 device.

(e = error in degrees) 5.3.3. Calculated analogue channels REC 523 includes virtual channels to obtain phase-to-phase voltages, residual voltage and neutral current when sensors are used. Current sensors and voltage dividers are connected to the feeder terminal via coaxial cables. Therefore a phase- to-phase voltage connection, an open-delta connection of phase voltages or a residual connection of phase currents cannot be made.
The dead band of the temperature change report is defined by the temperature delta parameter of the PSC board. Heating is needed if the REC 523 device is installed in a separate enclosure outdoors, where the ambient temperature may fall below -10...0°C. Heating is also required when the environment is very damp and dehumidifying is needed.
The figure below shows an example of a CAP application used for controlling a cooler. In this example, the temperature measured by REC 523 is forwarded to the COMH_1 function via the input PSC_7_Temperature, the value of which is compared to the values of the parameters Hlimit and Llimit.
Filter time of a digital input The filter time eliminates debounces and short disturbances on a digital input. The filter time is set for each digital input of the REC 523 device. The operation of input filtering is illustrated below.

1MRS750881-MUM Technical Reference Manual 5.7. Self-supervision (IRF) The REC 523 device is provided with an extensive self-supervision system. The self-supervision system handles run-time fault situations and informs the user of faults through the LON/SPA and remote communication protocol. 5.7.1. Fault indication The self-supervision signalling output operates on the closed circuit principle.
The Relay Configuration Tool is based on the IEC 61131-3 standard. The standard defines the programming language used for the configuration. The programmable system of REC 523 allows the output contacts to be operated in accordance with the state of the logic inputs and the outputs of the protection, control, measurement and condition monitoring functions.
5.8.2. LON network configuration The LON Network Tool is used for binding network variables between REC 523 units or other LON devices. Typically, LON is used for transferring status data between the REC units for the interlocking of the units, see Fig. 5.8.2.-1 .
5.8.3. Rated frequency When configuring the REC 523 device, the rated frequency of the device is also set via the Relay Configuration Tool. The set rated frequency cannot be changed afterwards via serial communication but it can be read via the global control parameter Rated frequency.
Store the parameters via the parameter Store, and reset the REC 523 device via the parameter Software reset by opening the Configuration tab and selecting General subtab.

Fig. 6.3.-1 REC52_ Communication overview 6.4. LON communication LON communication to/from REC 523 units falls into two categories: • Communication based on network variables • Communication based on explicit messages Network variables are used when communication need to be interoperable with other commercially available LON devices.
In REC 523, the ABB-specific solution for substation communication is supported by foreign messages. In short, the communication method consists of session control (REC 523 can maintain up to 4 sessions), a sliding window protocol for application acknowledgement and definition of data formats.
6.5. Virtual IEC 61131 inputs and outputs The REC 523 unit offers up to 64 programmable LON inputs and 64 outputs on the LON bus, 128 in total. The inputs and outputs use the LonMark Standard Network Variables (NV type 83 = SNVT_state and NV type 22 = SNVT_lev_disc) for sending and receiving process data.
The communication application works as an event receiver using the event filter number 1, which is set with the Relay Setting Tool parameter Event mask 1. This means that all application events generated within REC 523 and enabled by the application-dependent filter 1, are received by the LonMark communication application.
Page 56
IEC 61131 function block, the ID equals the function block ID number, for example, MEVO3A has the ID number 204. In REC 523, there are also events coming from the non-IEC 61131 applications. These are the events related to the battery and heating monitoring.
Page 57
REC 523 Remote Monitoring and Control Unit 1MRS750881-MUM Technical Reference Manual Event Mask1 and Event Mask2 In addition to the application-dependent filter 1 mask, the event is reprocessed through the LonMark mask. The masks are defined so that the setting of the bit 2^(event number) enables the event to be processed as a data event and sent out on the network variable output defined in the next column.
ID number. 3) SPA table format The SPA access can be used directly from the REC 523 SPA interface or any other protocol supporting the transparent SPA message transfer. The LonMark application number is 231. Table is number 1. Data category is M.

Page 60
Each SNVT_alarm output has its own event buffer. The size of each buffer is 50 events. Buffering contains local overflow, which means that overflow in LonMark event handling does not affect other event receivers in REC 523. The local overflow event is given with the location_id 231 (LonMark application’s individual application number) and event code 51.
