  • Page 57: Specific Instructions For Use In Explosive Atmospheres And Operational Safety

    Dust and Gas atmospheres. On account of their metrological performance as tested by the accredited organization INERIS (in process), the OLC/OLCT 100 transmitter detectors intended for the measurement of explosive gases are classed as safety devices in the sense of the European Directive and may, therefore, contribute to limiting the risks of explosion.

  • Page 58: Threaded Joints

    60079-1. TELEDYNE OLDHAM SIMTRONICS does not allow repairs and disclaims any responsibility for material modifications. The threaded joints on the OLC(T) 100 may be lubricated to maintain fire-proof protection. Only non-hardening lubricants or non-corrosive agents having no volatile solvents may be used.

  • Page 59: Scope Of Use

    The detector has been developed in conformity with standard EN/CEI 61508. The safety function of the OLC/OLCT 100 detector is the detection of flammable gases using catalytic technology and a 4-20 mA current output proportional to the gas concentration expressed as a percentage of LEL, respectively from 0 to 100% LEL.

  • Page 60: Reliability Data

    OLC/OLCT100 GAS DETECTOR USER MANUAL The safety function is no longer valid: • After power has been switched on, while the measurement sensor is stabilizing and during start-up tests, the output current shall be in maintenance mode (2 mA). • When the push button is pressed (forcing the current to 4 mA), the output current will be frozen at 4 mA.
