Commissioning
The installation and start--up of the electro--pneumatic actuators must be according to the best safety practices and
mainly:
Piping
:
Starting--up of a new installation requires cleaning the piping by air before connection to the actuator. This will remove any
impurities impossible to eliminate during construction (fillings, flux, paste, PTFE, etc.).
As a safety measure, the box is equipped with a filter in the input port to prevent clogging of the air valve by impurities. This
filter can be replaced (if clogged, the air valve does not work) by extracting it by means of a screw and inserting a new clean
filter.
Electric wiring
:
-- The electric components are “CE” marked in accordance with 94/9/EC and 2004/108/EC european directive.
-- The electric supply voltage and the electric values of the signals must be checked before connecting the components.
-- The components of the intrinsically safe electric loops should be checked to ensure the inputs and outputs as well as
wiring, do meet the regulations in force.
KSB--AMRI shall keep at the disposition of users the loop calculations for the recommended associated equipment.
-- An external earth terminal allows grounding of the metal parts of the control box.
Never exceed the values stipulated in this leaflet!
This box is a pressurized electric device. As such, it may be a source of danger for property or even personnel.
Any excess of these values may cause damage.
Never uncouple or disassemble the AMTRONIC EEx ia box or its accessories when pressurized or energized.
Always make sure that the actuator chambers are free from air pressure by pushing on the buttons for emergency control
of the pilots before disassembling the pneumatic valve, solenoid valvesor the box itself.
Also, always check that the fieldbus wires are disconnected before carrying out any disassembly.
During the mounting and dismantling of the boxes, take care the correct installation of all sealing gaskets. Quality and
integrity depends of this correct installation.
During workshop or on- site checking, the valve associated with the actuator and its AMTRONIC EEx ia box can
be operated from full open to full closed position.
This operation may be of a high significant risk of personnal injury if the safety steps required are not taken to
prevent access between the disc and the seat.
CAUTION !
WARNING
Electric connections
The electric connection is obtained via 2 packing--gland PG 13,5 (plastic or stainless steel).
Gland capacity: cable external dia. 8 to 13 mm, wiring to be connected to spring terminal max. are 2.5 mm
2
.
The good tightness of the box depends on cable selection and the tightening level of the packing--gland.
Pneumatic connection
