Pulscon LTC with HART, PROFIBUS PA or Foundation Fieldbus
Power supply
Category
Explosion protection
Max. operating pressure
Process temperature
T12 housing
Option
Observe the following installation instructions:
1.)
Install in accordance with manufacturer's specifications and the valid standards and regulations.
– Do not operate level sensor outside of the electrical, thermal and mechanical parameters.
2.) The Pulscon LTC must be included in the local potential matching line (PML).
The input circuit is galvanically connected to the housing.
3.) The relationship between the ambient temperature permitted for the electronics housing dependent on the application range
and the temperature classes can be found in the table (Tab. 1).
4.) After aligning (turning) the housing, the locking screw (see operating instructions) must be retightened.
4.1) Use connecting cable for continuous use temperature > T
4.2) Only replace cable glands with cable glands of the same type.
5.) Connection compartment cover: Do not open under voltage in an explosive atmosphere.
5.1) Do not open electrical connection of power supply circuit under voltage if an explosive atmosphere is present.
5.2) Connection compartment cover: tightening torque > 40 Nm.
6.) Only use the devices in media against which the materials in contact with the medium are sufficiently stable.
7.) The electronics compartment can be opened under voltage for configuring the device. Whilst the electronics compartment
cover is open, ensure that no dust can build up. Close electronics compartment after adjustment work, tightening
torque > 40 Nm.
8.) Mount the device such that mechanical damage or friction in the application are ruled out; observe flow profiles and internals
in particular.
