Caractéristiques techniques Ex importantes
Optionally the following modules are allowed to be used:
Plug-In module for
shutdown-function
(terminals +51 / -52 resp.
+85 / -86)
Electrical data for type TZIDC-110 with marking Ex nA IIC T6 resp. T4
Input circuit
(terminals +11 / -12)
Plug-In module for
shutdown-function
(terminals +51 / -52 resp.
+85 / -86)
Mechanical digital feedback
(terminals Limit1 +51 / -52
resp. Limit2 +41 / -42)
Special conditions
Only devices which are suitable for the operation in explosive 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
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 exceeded not more than 40 % by transient disturbances.
Special conditions
When using proximity switch SJ2_S1N (NO), the positioner
may only be used at an ambient temperature range of -25 ... 85 °C.
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.
