EQUIPMENT:
Equipment and systems covered by this certificate are as follows:
The Positioner type TZIDC-xxx is used for the control resp. closed loop control of pneumatic driven valves.
The Positioner type TZIDC resp. TZIDC-200 transfers the reference value by means of an impressed signal
current of 4…20 mA.
The Positioner type TZIDC-110, TZIDC-210, TZIDC-120 resp. TZIDC-220 transfers the reference value via
a field bus signal.
An integrated distance sensor measures the current position of the valve drive. An integrated
current/pressure transformer (I/P) is used for the pneumatic auxiliary power.
The permissible ambient temperature range in dependence on the type, the type of protection and the
Temperature Classes has to be taken from the following table:

CONDITIONS OF CERTIFICATION: YES as shown below:
Special condition for safe use of intrinsically safe Positioners:
The operation of the local communication interface (LKS) and of the programming interface (X5) is only
allowed outside of the hazardous explosive area.
Special conditions for safe use of Positioners marked Ex nA II T6:
Only devices which are suitable for the operation in explosion hazardous areas declared as zone 2 and the
conditions available at the place of operation are allowed to be connected to circuits in the zone 2.
The connecting and disconnecting as well as the switching of circuits under voltage are only permitted
during installation, for maintenance or repair purposes.
Note: The temporal coincidence of explosion hazardous atmosphere and installation, maintenance resp.
repair purposes is assessed as improbably.
For the circuit “Mechanical digital feedback” measures have to be taken outside the device that the rated
voltage is exceeded not more than 40% by transient disturbances.
Only non combustible gases are allowed to be used as pneumatic auxiliary energy.
Only suitable cable entries which meet the requirements of IEC 60079-15 are allowed to be used.
