Wiring diagram
The wiring of the angle sensor and transmitter assembly is carried out in workshop, the connection to the current loop is through the
terminal no. 10 for
and on the terminal no. 11 for
.
Two adjustments are available for the zero adjustment (4 mA) and the gain (20 mA).
When the AMTRONIC EEx ia box is delivered with its actuator, the assembly is preadjusted in workshop.

Pneumatic supply -- Pneumatic connection for AMTRONIC
The pneumatic valve works with 50
filtered air.
Before pneumatic connection, check the pipe is without impurities, mainly when starting--up.
As a measure of safety, the box is equipped with a filter in the input port in order to prevent the clogging of the pneumatic
distributor with the impurities.
This filter can be replaced if it is clogged (the distributor don’t work): extract it by means of a screw and put in the port a new
clean filter.
Working pressure from 3.5 to 7 bar (50 to 102 psi).
Pressure connection: port marked ’’P’’.
Exhaust connection: port marked ’’E’’ fitted with a silencer or connectable to
exhaust network.
