For the filling level sensors with connection terminals, the terminal designation are "+" and "-" and additionally "A"
and "B" for the type TORRIX
Ex… XT… ("+" and " -" are added for the type TORRIX Exd … for the terminal block
"Heater"). For devices with M12 plug, the pin assignments are as follows:
Pin
TORRIX Ex SC …
VISY-Stick …
TORRIX Ex C …
TORRIX Ex TAG …
VISY-Stick … TLS
TORRIX Ex RS485 …
VISY-Stick … RS485
M12 cable (female)
1 + + +
2 A A (+)
3 - - -
4 B B (-)
Table 1: Pin assignment of the sensors
The sensors must be integrated into the potential equalization of the hazardous area. A PA connecting terminal on
the sensor head is available for integration of the devices into the potential equalization.
General information (see also EN 60079-14:2013, clause 6.4.1):
Exposed conductive parts need not be separately connected to the equipotential bonding system if they are firmly
secured to and are in conductive contact with structural parts or piping which are connected to the equipotential
bonding system.
III.d … adjustment
For the operation the sensors, no Ex-relevant adjustments are necessary.
III.e … putting into service
Before putting into service, all devices must be checked for correct connection and installation. The electrical supply,
including the connected devices, must be checked. For the level sensors type TORRIX Exd
… , the cable entry and the
covers must be checked for correct installation.
III.f … maintenance (servicing and emergency repair)
The apparatus is generally maintenance-free. In the case of a defect, this must be returned to the manufacturer
FAFNIR or one of its representatives.
For equipment that is completely intrinsically safe, there is compliance in the dielectric strength test between the
intrinsically safe circuit and the chassis of the equipment with a voltage of 500 V
AC
in accordance with EN 60079-11,
Clause 6.3.13. For level sensors type TORRIX Exd … there is no compliance.
With the type TORRIX Ex … XTS … the display may be replaced. To do this, the cover of the display must first be re-
moved (see section III.b). By pushing in the flaps of the display, it can be levered out bit by bit. Particularly with the
TORRIX Exd
… version, care must be taken during th is procedure not to damage the enclosure and especially the
thread for the cover. The connections (plugs and sockets) on the back of the indicator must be disconnected. Now
the new unit can be connected. The number of poles and the polarity reversal protection of the connectors determine
the correct connection. After the electrical connection, the unit is placed in the grooves with the snap-in mechanism
(the orientation can be changed later, as the unit can be rotated in the enclosure. By pressing the flaps in again, the
display can be lowered into the enclosure until it clicks into place. After aligning the new indicator, refit the cover (see
section III.b).
Warning:
The type VISY-Stick Sump … and floats made of non -conductive plastic must only be cleaned with a
damp cloth, to minimize the risk of electrostatic charging.
Warning: The TORRIX Exd … version may only be opened without voltage.
