  • Page 10: Detector Connection

    2.2) Detector connection The detectors with 4-20 mA analog output are connected to the control unit, directly on the main board. For connection, the detector with 4-20 mA analog output requires a 3-conductor cable; 2 conductors for the power supply and one conductor for the 4-20 mA signal. The typical cable suggested is a 3 x 0.75 shielded cable that allows to reach a distance up to 100 mt between the gas detector and the control unit.

  • Page 12 2.3) PC programming The NFG-8 control unit can be programmed only by means of a Personal Computer with special software. The software has been studied for a simple and fast programming. The connection with the PC is via the RS232 serial port or via USB available on the main board of the control unit.

  • Page 13: System Start-Up And Operation

    SYSTEM START-UP AND OPERATION This chapter describes the procedures for operating the NFG-8 control unit. The NFG-8 control unit can be programmed only by means of a Personal Computer with the appropriate software. Fig. 3-10) Central front panel 3.1) Ignition After checking that the system has been installed correctly, the NFG-8 control unit can be switched on.

  • Page 14: System States

    Programming can only be done via Personal Computer with a special program. See chapter 4. For a system already configured, the screen in normal conditions will be the display of the channels (gas detectors) programmed. Maximum 3 channels per screen. Fig.
  • Page 15 System states The system may be in one of the following operating states: NORMAL ALARM FAULT TEST DISCONNEC EMERGENCY NORMAL It is the normal working status of the central unit, in absence of alarms and faults. The screen in this status will be the visualization of the channels (gas detectors) with the gas concentration measured in real time.
  • Page 16 In case there are Alarms from more than one gas detector the alarm screen will present the information of the different channels, as follows: • The information is sorted according to its importance: Off-Scale, Alarm3, Alarm2, Alarm1; • Off-Scale is considered an Alert state with the highest importance. By selecting an Alarm event and pressing the Enter key, a further screen will appear showing the details of the event.
  • Page 17 Fig. 3-7) Fault event details TESTING/MAINTENANCE This state is active when one or more channels are in TEST mode and is used to perform maintenance on the gas detection system. To put one or more channels in TEST mode the user must perform a special procedure, described later in the manual. The gas concentration measured by a sensor in TEST will be shown on the central unit display but will not generate an Alarm status if it exceeds a set threshold.

  • Page 18: Menu

    3.3) MENU In normal status, in the main screen appears the list of gas detectors managed by the central unit. Pressing the MENU button, the sub-menus described below will appear with the relative function. INSERT changes the status of the sensors and/or relays from Off to DISINSERT changes the status of the sensors and/or relays from switched on to switched off.
  • Page 19 press RST (Reset) to restore the central unit to normal status (this is possible only if ACK has been performed before and if the gas detector is no longer in alarm and/or fault status) PAGE - 16 Installation and Operation NFG-8 NOTIFIER ITALY Manual...
  • Page 20 At the occurrence of an event (alarm or fault), the buzzer of the central unit will sound and the display will pass to the visualization of the page Active Events where there will be the indication of the sensor in Alarm and/or Fault. To silence the central unit buzzer, turn the key to the central position (ACK) and press the ACK key, the central unit buzzer will stop sounding and an X will appear on the event line on the right.
