5.10 Connection terminal type A-G-247NW for serviceIf necessary an external terminal can be connected. This can be e.g. necessary to adapt the pre-setting during start-up.The connection is made by a 4-wire cable at the terminals: A (D+), B (D-) and GND. E. g. telephonecable type: J-Y (St) Y 2x2x0.6 (or similar), maximum cable length approx. 250 m.The voltage supply of the terminal is made by the accumulators inserted there or the plug powersupply unit.13.05.2013v_a-g-247nw_at_ecblue.vsdGND A(D+)B(D-) A-G-247NWECblue5.11 Digital input “D1” for enable (device ON / OFF)Electronic ON / OFF control via floating contact at terminals “+10V” - “D1” (input resistance andvoltage range Technical data).Function factory setting for “D1”:• Device “ON” for closed contact.• Device “OFF” with opened contact.Relay “K1” remains energized, connections 11 - 14 bridged.Status Out with flash code: |1|( Diagnostics / Faults).Danger due to electric current• No disconnection (no potential isolation in accordance with VBG4 §6) in remote control of thedevice!• Never apply line voltage to the digital input!5.12 Relay output “K1” for fault indicationAn external fault indicator is available over the potential-free contact of the built-in relays (max. contactrating Technical data and connection diagram).Function factory setting for “K1”:• For operation the relay is energized, connections “11” and “14” are bridged. For fault the relay is de-energized ( Diagnostics / faults).• When switching off via enable (D1 = Digital In 1), the relay remains energized.InformationAfter switching on the line voltage, an initialisation time of a maximum 7.5 seconds is required for thedevice's electronics to be operational. Subsequently, a reliable status message will be possible. If nomalfunction is detected, the relay will be energised after the initialisation time.Since both line voltage fluctuations and ambient conditions affect the initialisation time, a differentdelay might occur in individual cases.Assembly instructions ECblue Electrical installationL-BAL-F055D-GB 1634 Index 002 Part.-No.21/51
