AMTROBOX EEx ia R 1172

Specially designed for use with double acting ACTAIR and spring return DYNACTAIR pneumatic actuators and MR manual reducers,
this box integrates, in a modular form, the following electric functions:
• Position detection (opening and closing) by microswitches or inductive proximity detectors.
• Feed--back position by angle sensor and 4--20 mA transmitter (option).

AMTRONIC EEx ia R 1172

Specially designed for use with double acting ACTAIR and spring return DYNACTAIR pneumatic actuators, this box ensures the
following functions:
• Position detection (opening and closing) by microswitches or inductive proximity detectors.
• Feed--back position by angle sensor and 4--20 mA transmitter (option).
• On/off pneumatic distribution.

Fitted on to the top of the actuator housing, the AMTRONIC EEx ia box ensures the direct control of air supply to the actuator
and only requires one pneumatic and one electric supply, preventing thus the stacking of accessories such as limit switch box,
pneumatic valve, etc. and the various pneumatic piping and electric wiring systems.

Pneumatic supply - Pneumatic connection for AMTRONIC

The pneumatic valve works with 50 µ 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 8 bar (50 to 115 psi).

• Pressure connection: port marked ’’P’’.

• Exhaust connection: port marked ’’E’’ fitted with a silencer or connectable to
exhaust network.

WARNING
CAUTION !

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 89/336/EEC 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.

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.

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 mm2.
The good tightness of the box depends on cable selection and the tightening level of the packing--gland.

Pneumatic connection

 AMTROBOX EEx ia
AMTRONIC EEx ia

AMTRONIC EEx ia

The pneumatic valve works with 50 µm filtered air. Working pressure from 3.5 to 8 bar (50 to 115 psi).
Before connecting pneumatic supply, check the piping is clean, without any impurities, mainly when starting--up of a new installa-
tion.
As a measure of safety, the box is equipped with a filter in the input port in order to prevent the clogging of the distributor with
impurities. This filter can be cleaned if clogged (in this case, the air valve does not work): extract it by means of a wood screw and

Operating time adjustment (AMTRONIC EEx ia)

The operating time can be adjusted by means of two independent flow adjusters: one for opening and one for closure time.
Depending on the actuator type, the operating times can be adjusted as stated in the following table.

Double acting actuators Spring return actuators

For a shorter operating time than the min. one or for a longer operating time than the max. one, please consult us.
CAUTION!
The set screws of the exhaust flow rate adjustors are under line air pressure.
THEREFORE they must not be excessively unscrewed otherwise the screws may be expelled
by the pressure.
The top of the screw must not protrude from its hole by more than one millimetre.
Open/close position detection adjustment
The limit switches or detectors are factory adjusted.
It is not necessary to re--adjust before valve mounting on site.
Nevertheless, if you wish to re--adjust after a maintenance operation, proceed as follows:
-- Remove the cover of the box.
-- Put the disc in extreme position (opening or closing).
-- Unscrew the two metal screws one turn.
-- Adjust triggering of the required detector by turning the coloured screw corresponding to the colour of the cam to adjust.
-- Proceed in the same manner with the opposite switch.
-- Each cam is adjusted independently and the adjustment does not affect in any way the adjustment of the other cam.
-- When adjustments are completed, slightly tighten the two metal screws to prevent adjustments being changed.
-- Replace the cover of the box.

1 -- Loosen the metal screws 2 -- Adjust the cams 3 -- Tighten the metallic screws

Angle sensor adjustment

’’N’’ mounting
The Box / Actuator assemblies are delivered for “N” mounting on the valve. Angle
Box sensor
Any other mounting must be specified when ordering and requires a modification to
the position of the angle sensor. ED

If the actuator is designed for an “M” mounting, it is necessary to change the

position of the angle sensor in compliance with the opposite diagram.
To perform this operation, it is necessary to previously remove the cover and to disas-
semble the following in the given order:
-- the control solenoid valves (AMTRONIC EEx ia), ’’M’’ mounting
-- the pointer, Angle
-- the securing plate with the position detectors, Box sensor
-- the angle sensor attachment screw.
Now turn the angle sensor casing 90° and repeat the previous operations in reverse
order. ED

4--20 mA feed--back position adjustment

When the box is delivered with its actuator, the transmitter is preadjusted in workshop.
It is not necessary to re--adjust it before valve mounting on site.
Nevertheless, if you wish to re--adjust it after a maintenance operation, proceed as follows:
-- rRmove the cover of the box.
-- Remove the electric pilots (AMTRONIC EEx ia).
-- Remove the supporting plate of the position detectors to access to the transmitter.
-- Two adjustments are available for the zero adjustment (4 mA) and the gain (20 mA).
-- Repeat the previous operations in reverse order.

Zero adjustment (4 mA) : ±5%

Gain adjustment (20 mA) : ± 10 % Zero Gain
Accuracy : ± 1 % of full scale
