  • Page 6: Product Description

    PRODUCT DESCRIPTION The DGi-TT7-E is designed to monitor poisoning risk induced by the presence of toxic gases or vapours (hydrogen sulphide, carbon monoxide, ammonia...). The DGi-TT7-O is designed to monitor the oxygen concentration in %vol either for inerting (scales 1 or 5%vol.) or in breathable atmosphere control (Scale 0-25%vol). Both versions are equipped with electrochemical cells.

  • Page 7: Dgi-Tt7-E

    1.2. DGi-TT7-E The DGi-TT7-E is a MultiTox detector based on a transducer with electrochemical cell, which requires oxygen to function properly. The measuring principle is based on a redox reaction. In the event of a long period without oxygen, the measurement will not be representative of gases or vapours concentration.

  • Page 17: Installation

    INSTALLATION The detectors described in this manual are safety instruments intended to be installed in explosive atmospheres and have been designed in compliance with standards EN60079-0, EN60079-1, EN 60079-11, CEI 60079-0, CEI 60079-1 and CEI 60079-11. Intervention in some sites may be subject to restrictions that we invite you to follow for your own safety and those of others.
  • Page 18 4.2.1. Detector assembly Check the presence of the O-ring on explosion proof seal, make sure that it is correctly greased and has no visible damage. Plug connectors to the base, as described in paragraph “Electric connection”. Fit the main housing on the base, placing the cable excess in the base. Put in place and tighten the four M5 screws with their grower rings.
  • Page 19 4.2.3. Communication using the TLU 600 Communication elements are located above the display. The orientation enables a communication with an ½ horizontal angle about 35°, an ½ vertical-up angle about 30° and a vertical-down angle about 50°. The maximum communication distance is between 7 to 9 m. MultiTox : DGi-TT7-E/O &...

  • Page 20: Electric Connection

    4.3. Electric Connection Never adjust electric connections when detectors are powered. Maintenance must be undertaken by qualified staff. Observe safety site rules. MultiTox are sensors with standard current output 4-20mA or 0-22mA. The connection can be on 3 or 4 wires. The 4 wires configuration allows insulation between the signal and power loops.
  • Page 21 4.3.1. Installation recommendation This detector version is supplied in an electronic version Type-C. The terminal V- is isolated from the electric ground of the housing detector supplied with configurable current output type C (4-20 mA, factory configuration). But it can be modified in format 0-22 mA by the user, using one of the menus of the TLU 600.
  • Page 22 4.3.2. Connection of the electrical ground braid Use a shield connection clamp (not supplied) to connect the shielding of the cable to the electric ground of the housing (see § below). 4.3.3. Grounding A M4 screw passes through the body of the enclosure, enabling the electronic ground of the housing to be connected to the local ground.

  • Page 28: Operation

    OPERATION 6.1. Environmental conditions The lifetime of the electrochemical cartridges for toxic gas detector depends on the operating environment related to temperature, humidity and high exposures. One will take care to avoid long exposures to a hot and dry atmosphere (T°> 30°C and RH<10%), and gas exposures 4 times higher to the scale.

  • Page 29: Inhibition

    6.2. Inhibition Maintenance Inhibition is temporary. It appears during power up and maintenance. Inhibition stops automatically when the operator gets out of the maintenance menus or after 10 minutes if communication with the TLU has been interrupted. Maintenance inhibition can be configured in "frozen" mode (factory setting) or in "free" mode.

  • Page 30: Alarm Indication

    6.4. Alarm indication When an alarm status is confirmed, the backlight turns red. Moreover, the display indicates the alarm level and the current concentration. The remaining information which is usually recorded in the display cycle are not provided anymore, in order to keep the detection and current alarm level as a priority. If the alarm memorization is enabled, the backlight remains red and the alarm indication appears in the display cycle until the alarm is acknowledged with the TLU or until the detector is powered off, then powered on again.

  • Page 31: Display Indication

    6.5.
