Device installation
Devices are designed for wall mounting. There are two mounting holes at the
sides of the case. Working position is with sensor cover downwards.
The connecting terminals are accessible after unscrewing the four screws in
the corners of the case and removing the lid. Pass the connecting cable
through released gland and connect the wires to terminals (see
“Typical
application wiring”
). Tighten the gland and screw the lid (check the integrity
of the seal). The female connector for connecting T3110L transmitter
connect according to diagram at
“
Typical application wiring
”.
For device connection it is recommended to use a shielded cable with a
maximum length of 1200m. External diameter of the cable for T3110 and
T3110Ex connection is 4 to 8 mm. For T3311L connection use cable with
respect to female connector parameters (do not connect shielding at
connector side). When selecting the type of a cable for T3110Ex connection
and when choosing a location for T3110Ex mounting it is necessary to
observe the conditions for safe installation in potentially explosive
environments. The cables should be located as far as possible from potential
interference sources.
It is not recommended to use the device for long time under condensation
conditions or water aerosol conditions. It could be the cause of water steam
condensation inside the sensor’s cover with a consequential increase of
response time to humidity changes. It can cause sensor damage too.
Devices don´t require special operation and maintenance. It is recommend
to keep clean sensor cover and periodically to verify the accuracy of
measurement.
Warning
Installation, commissioning and maintenance may only be carried out by
personnel with qualification by applicable regulations and standards.
Ambient temperature of the housing with electronics of T3110Ex
transmitter is not allowed exceed 60
ºC.
Don´t connect transmitter while power supply voltage is on.
Under certain extreme circumstances, the plastic enclosure of T3110Ex
transmitter may store an ignition-capable level of electrostatic charge.
The device shall not be installed in a location where the external
conditions are conducive to the build-up of electrostatic charge. The
equipment shall only be cleaned with a damp cloth.
