  • Page 20: Buffer Battery

    Buffer Battery The exchangeable buffer battery ensures that the clock time (RTC) and SRAM data of the ETT 775 is preserved in the absence of a supply voltage. A lithium battery is installed at the manufacturer. After delivery of the ETT 775 and storage of one year, the lifespan of the battery reaches 10 years, if the device is in operation (supply connected) most of the time.

    BUILD-IN TOUCH TERMINAL ETT 775 Exchanging the Battery: 1. Option 1. Connect power supply 2. Using the correct cross-tip screw driver, loosen and remove the battery cover. When exchanging the battery, caution must be taken to avoid a short circuit since it could cause a defect in the terminal! 3.

    CAUTION: If the data is not previously saved, the settings in the ETT are lost. ATTENTION : Si les données ne sont pas sauvegardées auparavant, les réglages du ETT sont perdus. 2. Disconnect the ETT 775 supply 3. Using the correct cross-tip screw driver, loosen and remove the battery cover.

  • Page 23: Wiring Guidelines

    BUILD-IN TOUCH TERMINAL ETT 775 Wiring Guidelines Ground The terminal must be connected to ground via the assembly on the control cabinet or over the connection provided. It is important to create a low-ohm ground connection, only then can error-free operation be guaranteed. The ground connection must be made with the maximum cross section and largest (electrical) surface possible.
  • Page 24 ETT 775 BUILD-IN TOUCH TERMINAL RS485 • Because the RS485 requires a defined quiescent point, a pull-up and pull-down resistor is required in addition to the termination resistor. The resistors are already implement- ed in the device. • The 120 Ω terminating resistors must be placed at each bus end.

  • Page 25: Tty

    BUILD-IN TOUCH TERMINAL ETT 775 7.6.1 General Data/Specifications • For wiring data cables, twisted pair cables with shielding must be used! • Maximum bus participants during active operation: The sum of the voltage drop of all participants (Rx, Tx) including on cables and connectors should not exceed 30 V (this corresponds in practice to 3-6 participants).

  • Page 27: Can Bus Setup

    BUILD-IN TOUCH TERMINAL ETT 775 CAN Bus Setup This section explains how to configure a CAN bus correctly. The following parameters must first be set: Station number and data transfer rate. CAN Bus Station Number Each CAN bus station is assigned its own station number. With this station number, data can be exchanged with other stations connected to the bus.

  • Page 28: Can Bus Termination

    ETT 775 BUILD-IN TOUCH TERMINAL CAN Bus Termination In a CAN bus system, both end modules must be terminated. This is necessary to avoid transmission errors caused by reflections in the line. The termination is made by an internal 120-Ohm resistor between CAN A (LOW) and CAN B (HIGH).
