  • Page 2: Introduction

    1.1 Getting Started How to prepare the EDM 35 for use For convenience you have a check list below to be sure that all prepara- tions of the EDM are made before the application. Page references are mentioned so you can easily find the point in question in this manual. If the EDM is received in modules start at point 1, otherwise start at point 6.

  • Page 3: Overall Description

    - Power Supply modules for AC or DC supply as well as excitation supply for sensor supply ® - Interface to Carlo Gavazzi’s Dupline Field and Installation Bus The large variety of input signals of both electrical and industrial process variables make the EDM an extremely versatile instrument suitable for many applications.

  • Page 4: Block Schematic

    1.4 Block Schematic Main unit Display and control Output Power supply Relay output Input analog/exitation 2.1 Modules 2.1.1 Common description The modules are parted into 3 categories: Power supply modules, input modules and output modules. Each module is dedicated to its own function or input variable.
  • Page 5 2.1.2 Variants 2.1.2.1 Power Supply Modules You will always need the power supply module. These are available for the most common supply voltages. Due to the size of the transformer the power supply module always occupies 2 slots. 2.1.2.2 Input Modules The input modules are divided into the following categories: Voltmeters (AC or DC)
  • Page 6 2.1.2.3 Output Modules The output modules are divided into the following categories: Relay output (1 or 2 relays) Analogue output (4-20 mA, 0-20 mA and 0-10 V) Excitation output (for sensor supply) Depending upon the application you can choose between different out- put types: An output module with 1 or 2 relays and/or an output module with analogue output where you are able to select the required type of analogue output with the jumpers.

    2.2 Main Unit 2.2.1 Description The main unit includes a 3 1/2 digit, 7-segment display with alarm indi- cators, a motherboard for 1 power supply module and 3 input/output modules, a processing unit and a keyboard. You can use the main unit as a 3 1/2 digit indicator when inserting only a power supply module and an input module.

  • Page 9: Installation & Operations Before Use

    & & & & 3.1 Procedure Before the instrument is ready for use, i.e. before it is ready for the ap- plication dependent programming, you have to prepare the instrument physically (engineering unit, modules etc.) - this is described in chapter 3.2 Installation.

  • Page 10: Rated Operational Voltage

    If you later want to replace the engineering unit (3), you insert a screw- driver into the lateral slot in the front panel and turn (be careful!) the screwdriver as shown until the front panel has been completely removed. Replace the engineering unit. You can find the panel cutout and the mechanical dimensions in chapter 7.3 Mechanical Dimensions.
