6.2 Notes on combinations of sensors and transmitters
The correct assignment of the transmitter to the sensor must be ensured for the following combinations
in Ex-zone 1.
The sensor is marked with the ending X01, X02, etc. on the nameplate in the order number.
The corresponding transmitter is marked with the ending X01, X02, etc. on the nameplate in the order
number.
IMPORTANT (NOTE)!
The following points must be checked before startup:
•
The voltage supply must be switched off.
• The voltage supply must match the specification on the nameplate.
• The pin assignment must correspond to the connection diagram.
• The sensor and transmitter must be grounded properly.
• The temperature limit values must be observed.
• The transmitter must be mounted at a location that is largely free from vibrations.
• The case lid and its lock must be sealed before switching on the voltage supply.
• For devices with a remote mount design and an accuracy of 0.2 % of the measuring value, make
sure that the sensor and the transmitter have the correct assignment: sensors have the last digits
X1, X2, etc. printed on the nameplates: transmitters have the last digits Y1, Y2, etc. printed on the
nameplates; devices with the last digits X1/Y1 or X2/Y2 belong together.
• Unused screw connections must be sealed with the provided plugs according to IEC 60079 prior to
startup
