  • Page 4: Introduction

    Mains operated UNICOM 300 is a (GSM-CSD/GPRS/LTE cat.1) 2G/4G modem and data logger. The inputs are equipped with Ex barriers so that mains operated UNICOM 300 may be used with equipment that is placed in a zone 0 with a potentially explosive atmosphere.

  • Page 5: Explosion Safety Instructions (Ex)

    Manual DDN5006GHEN (this manual) should be read and understand completely before installing and put into use UNICOM 300 N531. Does any question arise or clarification is needed with regard to explosion safety with respect to UNICOM 300 N531, please contact Wigersma & Sikkema.
  • Page 6 Installation and user manual UNICOM 300 N531 Additional instructions on explosion safety for use with external antenna: Replacing the antenna with a type other than the ones recommended is not recommended, see manual DDN5006GHEN (this manual) for additional information. Prevent damaging the cable of the external antenna during installation. If the cable is damaged, the antenna should be replaced as a whole with a non-damaged unit.

  • Page 7: Inputs And Data Structure

    Mains operated UNICOM 300 has two pulse outputs that can transmit pulse or alarm. Mains operated UNICOM 300 is able to count two pulses in two counters, read an encoder counter in a third counter and log it in an interval logger.

  • Page 8: Installation

    See DDN5002MHML installation manual for installation/assembly options and installation instructions. This manual can be downloaded from www.wigersma-sikkema.com. It is not necessary to open the UNICOM 300 to mount the mounting brackets to a gas meter or to the wall. 4.2 Dealing with mains voltage First read the provisions for explosion protection, see chapter 2 Explosion protection instructions (Ex) or the DDN5802CVML EU Declaration of Conformity and Safety instructions UNICOM 300 N531.

  • Page 16: Activation And Registry

    (see chapter 5.4). 5.6 Out of service If it is necessary to deactivate the UNICOM 300 (take it out of service), it must be ensured that the modem is not active! This can be checked by activating SW1 for 1 second (see table 3, from firmware version 11.0.21) or activating the communication port SW2 which causes the status LED to display.

  • Page 19: Configuration

    If an encoder counter is connected without initializing it and the position of the encoder counter is lower or much higher than the value in counter 3 (Vm3) of UNICOM 300, UNICOM 300 will not take over the encoder counter mode. In the status register a message is made of an incorrect readout of the encoder counter.

    Check and / or program the correct pulse ratios (parameter 1:0.7.2 and 2:0.7.2) by means of the UNITOOL service software. For UNICOM 300 pulse outputs, a choice can then be made for Vm1-Vm2-Vm3 or Alarm1 via the parameters mentioned in chapter 11.
