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.
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.

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.
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.
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.
Make sure that when closing the lid it is not pushed up or down. Make sure that the sealing ring in the lid is clean. (3) Breather opening for pressure equalization between UNICOM 300 and ambient atmosphere. Behind the breather opening a membrane is placed that prevents ingress of moisture.

Insert the power cable through the appropriate cable gland (Fig. 6, 1). Connect the power cable to the 230 VAC or 24 VDC terminal in the UNICOM 300 (fig. 6, 5). Screw the terminal and the cable gland tight and fit the Ex-protection cap (fig. 6, 7).
Connection for Encoder Table 2: connections inputs See Appendix 3 for connection diagrams for UNICOM 300 - UNIGAS 300. In order to make a good connection between the threaded ends and the connection terminals (see Figure 7, 1 and 7, 2), it is important to ensure that the connection terminals are first fully unscrewed.
APN; such as APN name with the corresponding username and password. 5.2 SIM-card placement Open UNICOM 300 (see figure 3, note 2). The mini-SIM holder is located in the lid of the UNICOM 300 (see figure 5).
(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.
NETWORK status LED (see Chapter 5) is off for a short time. 6.2 Activation of TCP services If the TCP server function is activated in UNICOM 300, the device will log on to GPRS/LTE cat. 1 when the modem is switched on.

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.
