  • Page 10: Installation

    INSTALLATION OPTISWIRL 5080 3.1 Mounting Installation and setup must be carried out according to the applicable installation standards (e.g. EN 60079-14) by qualified personnel trained in explosion protection. The information given in the manual and these instructions must always be observed.

  • Page 11: Special Conditions

    • As aluminium is used at the accessible surface of the signal converter housing, in the event of rare incidents, ignition sources due to impact and friction sparks could occur. This shall be considered when the OPTISWIRL 5080 vortex flowmeter is being installed in group IIC, zone 0 classified locations.

  • Page 12: Electrical Connections

    ELECTRICAL CONNECTIONS OPTISWIRL 5080 4.1 General notes The separate intrinsically safe signal circuits are electrically connected in the terminal compartment of the signal converter. The circuits are designed in type of protection "intrinsic safety" and galvanically not isolated from ground.

  • Page 13: Outputs

    ELECTRICAL CONNECTIONS OPTISWIRL 5080 4.3 Outputs The terminal assignment is described in the standard manual. The signal circuits of the vortex flowmeters must only be connected to certified intrinsically safe circuits. For more information refer to chapter "Electrical data". The 4...20 mA current output circuit and the pulse output circuit are galvanically isolated from each other.

  • Page 14: Operation

    OPERATION OPTISWIRL 5080 5.1 Start-up Start-up may only initiate when the vortex flowmeter: • is correctly installed in the system and connected. • has been checked for the proper state with regard to its installation and connection requirements. • has been correctly locked to the electronics and terminal compartment.

  • Page 15: Service

    SERVICE OPTISWIRL 5080 6.1 Maintenance Maintenance work of a safety-relevant nature within the meaning of explosion protection may only be carried out by the manufacturer, his authorised representative or under the supervision of authorised inspectors. Fluids containing abrasive particles and flowing at high rates can cause significant wear to pipes.
  • Page 16 SERVICE OPTISWIRL 5080 Exchanging the entire device The dismantling and installation is within the responsibility of the operator. Before disconnecting the electric connection cable of the device, make sure that all cables leading to the indication unit are isolated from the ground of the hazardous area.
