TypeAI638P...........II2GEExiaIICT6

Types of protection and temperature classes as basic device.

For use in hazardous areas in circuits certified as intrinsic-

ally safe with the following maximum values:

Ui= 16 V, Ii= 80 mA, Pi= 250 mW

Internal capacitance and inductance: Ci= 26 nF, Li= 5 µH

The electric circuits of "2 binary outputs" are galvanically

separated from all other circuits and from ground.

The binary output for Alarm will be activated in the following

cases:

- Remaining control deviation

- Circuit to I/P module is disturbed

- Circuit to potentiometer is disturbed

- Calibration error:

- no angle calibration

- no current calibration

- Autostart failed

These pre-settings can be configured via communication
