  • Page 6: Brief Description

    Function Expansion Unit FE260 1 Brief description The Function Expansion Unit FE260 is used for expanding the functions of a volume corrector in the LIS-200 range, such as for example the EK260 from software version 2.02. In the current level of expansion it fulfils the following tasks: Intrinsically safe power supply for the volume corrector.

  • Page 8: Mounting

    Function Expansion Unit FE260 2 Mounting The holes for wall mounting become accessible after opening the housing cover of the FE260. The dimensions, drilling template and diameter of the mounting holes can be taken from Fig. 3 and Fig. 4.
  • Page 9 As “associated electrical equipment”, the FE260 cannot be installed in Zone 1. (See [DIN] EN 60079-10 and [DIN) EN 60079-14.) For versions of the FE260 with a GSM modem, the supplied antenna must be mounted, e.g. on the wall. A mounting bracket is provided in the supplied items for this.

  • Page 10: Installation

    3.1.2 "DC" version (for direct voltage of 10 to 30 V) The "DC" version of the FE260 is suitable for a direct-voltage power supply in the range from 10 to 30 V. It can be operated, for example, with nominal voltages of 12 V or 24 V.

  • Page 11: Screening And Earthing

    A1 to A4 have a screen which must be earthed at both ends to prevent interference due to high frequency electromagnetic fields.. The screen must be connected all round, complete and flat. The FE260, similar to the volume corrector (e.g. EK260) to be connected, has special metallic EMC cable glands for this.

  • Page 12: Cables And Cable Lengths

    , offer the possibility of operating Output 2 as a high frequency output at up to 500 Hz. The connection “DA2” on the FE260 is specially rated for this. Consequently, the above mentioned degradation of the signal (see *3) is substantially less here.

  • Page 13: Terminal Layout

    Cable 2 On the EK260 the terminals “R+”, “R-“, “T+” and “T-“ are also labelled with “CS”, “RD”, “RS” and “TD”. When connecting the FE260, these designations have no significance. The terminals “Ri” and “Gnd” on the EK260 remain unconnected.

    “Technical Data”. 3.5 Modem On request, the FE260 can be fitted with an integral modem or a connection for a separate modem in order to read out the data from the connected volume corrector by remote data transmission.

  • Page 15: Integral Gsm Modem

    Only use the top centre plastic gland for the antenna cable so that the point of connection does not form a short circuit to the earthed housing. Then the antenna cable is connected to the modem within the FE260 using the short cable.

  • Page 16: Connection Of A Separate Modem

    For the connection of a CL modem: refer to Chapter 3.5.4, page 17. If the FE260 is implemented with a connection for a separate modem, you can connect a commercially available modem to it to read out the volume corrector by remote data transmission.

  • Page 17: Connection Of A Cl Modem

    CL modem and also on the connected devices: The sum of the voltage (in volts) required by the connected devices must not be greater than the driver rating of the CL modem. The CL interface of the FE260 requires 3 V. Wiring diagram:...

  • Page 18: Initial Operation

    • Once all cables are connected and the housing firmly closed, switch on the FE260 power supply (mains voltage for the "AC" versions). • Check the “Power” signal lamp on the cover of the FE260. A continuous green signal indicates that the FE260 power supply is functioning correctly.

    FE260 with the option "Local interfaces" or "CL interface"). *2) 19200 Bd is standard. With longer lengths of cable between the FE260 and the volume corrector (refer to Chapter 0, page 12) and when using the option "Local interfaces" or "CL interface", the baud rate may be set to a maximum of 9600 Bd.

  • Page 21: Cl Modem

    These volume correctors can be operated without restriction. If other bus devices are connected to the CL modem as well as the FE260, you must assign an unambiguous bus address to the volume corrector. This address is used by the calling software to select a device.
  • Page 22 → The modem must be suitably parameterised for the parameter "Md.S2" in the volume corrector: With "Md.S2 = 5" the modem accepts calls automatically, with "Md.S2 = 3" it does not. If the FE260 is fitted with the option "Local interfaces" or "CL interface", the modem must accept the calls automatically.

  • Page 23: Local Interfaces (Optical Interface And Rs-232)

    (No call acceptance by the volume corrector, setting Md.S2 = 5). • When using an FE260 with optical interface, operation occurs with a baud rate of 9600 Bd. On the volume corrector, apart from the displayed baud rate "Bd.S2", the so- called "Identification baud rate"...

    4.4.2 Parameterisation of the modem integrated into the FE260 When the switch S2 is set to "Modem par.", the modem integrated into the FE260 can be parameterised with the aid of a PC or laptop. The serial interface of the PC or laptop is in this respect connected to the optical interface or to the DSUB-9 connector.
