This manual is a K-QNA500 installation guide. For further infor-mation, please download the full manual from the CIRCUTOR web site: www.circutor.com

IMPORTANT!

The device must be disconnected from its power supply sources (power supply and measurement) before undertaking any installation, repair or handling operations on the device’s connections. Contact the after-sales service if you suspect that there is an operational fault in the device. The device has been designed for easy replacement in case of malfunction.

The manufacturer of the device is not responsible for any damage resulting from failure by the user or installer to heed the warnings and/or recommenda-tions set out in this manual, nor for damage resulting from the use of non-original products or accessories or those made by other manufacturers.

1. DESCRIPTIONK-QNA500 power quality analyzer measures and records the main electrical parameters of industrial three-phase grids. Measurements are taken in RMS values via four AC voltage inputs, four AC current inputs and one leakage current input.

The K-QNA500 kits are composed of the following elements:

K-QNA500, a BASE module and a measurement module (QNA500).K-QNA500 8IO, a BASE module, a measurement module (QNA500) and an inputs-outputs module (opto-MOSFET) 8IO. QNA500 8IOR, a BASE module, a measurement module (QNA500) and an inputs-outputs module (relay) 8IOR.

The K-QNA500 kits are fully configurable and programmable with the system’s built-in WEB server or with specific software supplied by CIRCUTOR.

2. INSTALLATIONThe power quality analyzer must have a circuit breaker or equivalent switch to disconnect it from the external power supply. Likewise, it must have GL (IEC 269) or M fuses, rated 0.5 to 2 A.

IMPORTANT!

Take into account that when the device is connect-ed, the terminals may be hazardous to the touch, and opening the covers or removing elements may provide access to parts that are dangerous to the touch. Do not use the device until it is fully installed

2.2 BatteryThe battery is not connected to the BASE module to avoid its discharge. Therefore, it is very important to connect the battery sup-plied with the BASE module in order to make sure that the analyzer continues measuring when the power supply is cut off. To do so, remove the side cover of the BASE module and connect the battery using the 2-pin connector. Finally, close the side cover to make sure that the battery is correctly inserted.

2.3 Inserting modulesTo add a module to your unit, first fit it using the 26-pin connector located on the side of every unit. To do so, align the two connectors and press them gently until both modules have fit together correctly.

2.4 Fastening clampsUse the plastic clamps (6 units) supplied with the analyzer to secure the attachment of the BASE module and the K-QNA500 unit. These clamps must be placed in the slots located at the top and bottom of the modules in order to reinforce the fastening.

2.5 Mounting the module on a DIN Rail or PANEL baseThe K-QNA500 analyzer is supplied with a set of guides for installing the unit on a DIN rail or PANEL base. To do so, follow the instruc-tions described in section Mechanical attachment options

2.6 Connecting power supply The analyzer is powered via the BASE module. Always connect the analyzer in accordance with the specifications stated by the manu-facturer on the adhesive label attached to the analyzer.

2.7 Connecting measure QNA500 module is used to take voltage and current readings.Check the state of the LEDs to make sure that the voltage and cur-rent measurements have been taken correctly. These LEDs can be used to check that both the voltage and current sequences were performed correctly, as stated in table LEDs BASE and QNA-500.

2.8 Connecting input-outputs 8IO and 8IOR has 8 digital configurable inputs and 8 outputs (relay or transistor depending on the model). Inputs are active when an external contactor is closed using a common reference C.IN. Outputs also are closed using a common reference C.OUT. To connect wires, 2 terminal strips with 9 screws’ each one. Inputs and outputs have a specific position for its common terminal.

3. BASIC PROGRAMMING OF THE MEASURE-MENT MODULETo configure the unit, communication must be established with the BASE via one of its communication ports. K-QNA500 power quality analyzer measures a large number of electrical parameters and thus offers many different configuration options. This section describes the various configuration procedures. Open the web server menu to access the configuration options.

3.1. Configuration via RS-232 portThe cable supplied with the analyzer must be used to configure it via the RS-232 port. This port supports the following protocols: CIRBUS, MODBUS/RTU, MODBUS/TCP and ZMODEM.

3.2 Configuration via RS-485 portThis port can be used to integrate the K-QNA500 analyzer in a standard RS-485 network with additional peripherals. Similarly, the BASE module acts as a gateway with all devices connected to this bus, making it possible to connect other devices that communicate using the MODBUS/TCP protocol and to use this module as a com-munication gateway.

3.3 Configuration via Ethernet portSetup IP address: MULTIFIT modules are deliver in DHCP mode enable. This means that when this device is connected to a LAN network, DHCP server gives an IP address automatically to each module. To change this IP address or assign a FIX IP address, please use IP Setup software. You can download this software from our web page www.circutor.comTo setup an IP address through IPSetup software, you must in-troduce MAC address (attached in a stick label in the device), IP address that you want to use, subnet mask and gateway address supplied by IT manager. Once IP address is send, IPSetup open automatically your default web-browser with the device WEB Server.If you setup in local mode an IP address, you must connect an RJ45 UTP cable between your computer and BASE. Then you must change IP address from your computer, introducing an IP of the same range of the MULTIFIT modules. Then, using IP Setup software, you can modify IP addresses of MULTIFIT modules. Device number setup: MULTIFIT modules are published in the BASE module by using device number In case of many modules connected to the same BASE, you must be sure that any module has the same device number. If this happens, only one module will be able to com-municate. Device numbers can be change using Web Server. To see more details, please check user manual.

3.4. K-QNA500 - Parameters to configureThis menu can be used to program the primary and secondary volt-age and current ratios.• Prim. V: Programs the primary winding of the voltage transformer. It must be set to “1” when no transformer is used.• Sec. V: Programs the secondary winding of the voltage trans-former. It must be set to “1” when no transformer is used.• Prim. I: Programs the primary value of the current transformer. The maximum value is 9999 A. • Sec. I: Programs the secondary value of the current transformer. The following values can be programmed: …/5 or …/1.• Prim In: Programs the primary value of the neutral current trans-former. The maximum value is 9999 A.• Nominal voltage: Programs the reference voltage value of the analyzer. This value will be used to record events, which are ex-pressed as a % of the nominal voltage.• Nominal frequency: Programs the mains frequency value (50 or 60 Hz).• Circuit type (3 or 4 wires): Selects the type of electrical network to which the analyzer is connected (3 or 4 wires). If a 4-wire network is programmed, the variables will be monitored from the neutral and the nominal voltage will be Vp-n.• Recording period: Adjusts the time value used when recording information (except for energy). The default value is 10 minutes.• Energy recording period: Adjusts the time value used when recording energy. The default value is 15 minutes.• Battery disconnection time: Adjusts the time during which the analyzer will continue to operate after the external power supply has been turned off. The maximum time is 15 minutes.

4. COMMUNICATIONSThe MULTIFIT system allows several QNA500 modules to be con-nected to the BASE module. Therefore, the same Ethernet bus can be used to send queries to different peripheral devices. At the same time, one or more K-QNA500 8IO analyzers can be connected to a computer or PLC via RS-485 bus. The K-QNA500 8IO analyzer has an RS-485 communication output. A peripheral number (01 to 255) will be assigned to each analyzer connected to the RS-485 communications bus.Please consult the relevant chapter of the full manual on how to change the communication configuration. RS-485 connection uses a mesh-shielded twisted-pair communica-tion cable with at least three wires, with a maximum distance of 1,200 m between the master and last unit and a maximum of 32 units in series.
