    ● Repairs and maintenance must only be carried out by special- ist technicians or other suitably trained personnel. Only spare parts approved by Hermann Sewerin GmbH may be used when performing repairs. ● Use only suitable battery types, otherwise the device will not be explosion-proof.
  • Page 9: Purpose

    All tasks that can be performed with the device are assigned to applications. For more detailed information please see Section 1.5 on page 5. WARNING! The VARIOTEC 460 Tracergas is not a gas warning in- strument. ● Do not use the device to warn against dangerous gas concentrations.
  • Page 10: Intended Use

    5%, the device must be used in carrying bag TG8. ● SEWERIN recommends always using the device in carrying bag TG8 in enclosed spaces. ● Do not use this device in oxygen-enriched atmospheres, oth- erwise it will not be explosion-proof.
  • Page 12: Allocation Of Tasks To Applications

    1 General Allocation of tasks to applications The device is used in measuring mode in four applications: ● Inspection above ground ● Measuring in bar holes ● House ● Gas measuring Owing to the high sensitivity in the ppm range, the Inspection above ground and House applications are particularly suitable for leak detection but less so for reproducible measurements.
  • Page 13: Tracer Gas Method

    (e.g. screed, concrete). This penetrating power is used to locate gas leaks in closed systems with a gas measuring device such as the VARIOTEC 460 Tracergas. Such closed systems may either already exist (e.g. filling stations) or may have to be created. In the latter case the pipe sections to be inspected are closed off with blind flanges, for example.
  • Page 14: Features

    2 Features Features Visual and audible signals The device features two alarms: ● Signal light on top of device (visual signal) ● Buzzer on side of device (audible signal) If this symbol appears on the display, the audible signal can be switched off. When an audible signal has been switched off it cannot be switched back on while the concentration level remains above the alarm threshold.
  • Page 15: Sensors

    2 Features Dynamic or constant signal for ALPPM For the ALPPM alarm there are two options for cycling the audi- ble and visual signals: ● dynamic (dynamic signal) ● constant With the dynamic signal option the cycle speed is dependent on the measured gas concentration.
