1. The unit is not equipped with an internal fuse or power supply circuit breaker Because of this an external time delay cut out fuse with minimal possible nominal current value must be used recommended bipolar max 2A and a power supply circuit breaker located near the unit In the case of using a monopolar fuse it must be mounted on the phase cable L The power supply network cable diameter must be selected in such a way that in the case of a short circuit of the cable from the side of the unit the cable shall be protected against destruction with an electrical installation fuse Wiring must meet appropriate standards and local regulations and laws In order to secure against accidental short circuit the connection cables must be terminated with appropriate insulated cable tips Tighten the clamping screws The recommended tightening torque is 0 5 Nm Loose screws can cause fire or defective operation Over tightening can lead to damaging the connections inside the units and breaking the thread In the case of the unit being fitted with separable clamps they should be inserted into appropriate connectors in the unit even if they are not used for any connections Unused clamps marked as n c must not be used for connecting any connecting cables e g as bridges because this can cause damage to the equipment or electric shock If the unit is equipped with housing covers and sealing packing protecting against wat2. 10 2 TRANSMISSION ERRORS DESCRIPTION If an error occurs while write or read of single register then the device sends an error code according to Modbus RTU specifications example message no 1 Error codes 01h illegal function only functions 03h 06h and 10h are available 02h illegal register address 03h illegal data value 08h no write permission see mbAc parameter AOh exceed of upper border of input range 60h exceed of lower border of input range AOh and 60h codes can appear only during reg 01h is reading by 03h function read of a single register 10 3 EXAMPLES OF QUERY ANSWER FRAMES Examples apply for device with address 1 All values are represent hexadecimal Field description ADDR Device address on modbus network FUNC Function code REG H L Starting address address of first register to read write Hi and Lo byte COUNT H L No of registers to read write Hi and Lo byte BYTE C Data byte count in answer frame DATA H L Data byte Hi and Lo byte CRC LH CRC error check Hi and Lo byte 1 Read of the displayed value measurement WW 30 device address 01h ADDR FUNC REG H L COUNT HL CRC L H 01 03 00 01 00 01 D5 CA a The answer we assume that measurement is not out of range ADDR FUNC BYTE C DATA H L CRC LH 01 03 02 00 FF F8 04 DATA H L displayed value 255 no decimal point Decimal point positio
