GENERAL INSTRUCTIONS TECHNIC
Technica
The device contains electronic components that are sensitive to
electrostatic charging (ESD). These components are
endangered by contact with statically charged persons or
objects. In the worst case they are immediately destroyed or fail
after putting into operation.
Observe the requirements of EN 100 015-1 in order to minimize
or avoid the risk of damage by instantaneous electrostatic
discharge. Make sure also that you do not touch electronic
components when they are under supply voltage.
ATTENTION!
CAUTION ON HANDLING!

General description
• For installation and operation in potentially explosive environments,
observe the relevant national regulations. (in Germany: VDE 0165)
• The device serves exclusively to drive process valves of types
6520 and 6521 NAMUR
- Driving of four type 6520/6521valves (PTB n° Ex-97.D.2089x)
- Connection of two sensors per valve (see table)
• The line resistance to the sensors and valves shall be not more than
20 Ohm for a max. cable length of 30 m.
• Use only shielded cable for connecting the sensors and valves.
Note also that the screening must be connected, e.g. at the front
panel of the housing.
The values of the capacity and inductance are specified in the
conformity certificate.
Please observe the instructions of the
Conformity Certificate PTB Nr. EX-97.D.2089X for the supply of the
valve. More information regarding the operation and installation of
the type 6115 (6520) valve can be found in the operating
instructions for these valves.
