5.11 Connection of external Terminal type AXG-1A(E)An external terminal is required for starting-up and setting-up versions that do not have an integratedterminal.• Model AXG-1A, Part-No. 349034 for wall mounting• Model AXG-1AE, Part-No. 349008 for panel mountingConnection Terminal TypeAXG-1A(E)The connection is made via a 4-strand line at the terminals of plug (D-, D+, GND and+24 V).e.g., telephone flex e.g. J-Y (St) Y 2x2x0.6 (or similar), maximum line length ca. 250 m.- Voltage supply: Terminal “24 V”, “GND”, (Imax, for terminal approx. 50 mA)- Signal “D+” and “D-” (RS 485)If the Modbus® interface is used for network a “Z-Modul-A” (Part.-No. 380054) is necessary to use anexternal terminal at the same time.5.12 Digital inputs (D1, D2)Various functions can be allocated to the digital inputs “D1” and “D2” ( IO Setup: Functionssummary of the digital inputs). Activation via floating contacts (a low voltage of ca. 24 V DC isconnected).Danger due to electric currentNever apply line voltage to the digital input!It is not permissible to connect inputs of several devices to each other!5.13 Relay outputs (K1, K2)Various functions can be allocated to the relay outputs “K1” and “K2” ( IO Setup: function andinverting relais outputs). Max. contact rating technical data and connection diagram.Connection of the floating contacts of relay “K1” to the terminals 11, 14, 12. Connection of the floatingcontacts of relay “K2” to the terminals 21, 24, 22.5.14 Communication5.14.1 Networking via MODBUS-RTUThe device comes equipped with a RS-485 interface for networking via MODBUS. Conntection at: “A(D+)”, “B (D-)” and “GND”.The address must be set in the “IO Setup” menu.InformationA maximum of 64 members can be directly connected to one another, and another 63 members via arepeater.5.14.2 RS-485 - network design and interface parameterPlease ensure the correct connection; i.e. "A (D+)" must always be connected to "A (D+)" of the nextdevices. The same applies to "B (D-)" .In addition, a "GND" connection must be established, as dissimilar potential (over 10 V!) will lead tothe destruction of the RS-485 interface (e.g. lightning).Operating Instructions Icontrol – model series FXDM Electrical installationL-BAL-E036-GB 1422 Index 008 Part.-No. 00154773-GB15/96 |
