2.3 Explanation of symbols and notices
This documentation contains notes that you must observe for your own
personal safety and for the avoidance of damage to property. Notes con-
cerning personal safety are highlighted by a warning triangle; notes con-
cerning only damage to property are not marked by a warning triangle.
Depending on the danger level, the warning notes are shown in decreas-
ing order of severity as follows:
DANGER
means that death or serious injuries will occur if the corresponding
preventive measures are not taken.

European directives:
2014/30/EU
EMC
Directive of the European Parliament and of the
Council on the harmonisation of the Laws of the
Member States relating to electromagnetic com-
patibility.
2014/34/EU
ATEX
Directive of the European Parliament and of the
Council on the harmonisation of the Laws of the
Member States relating to equipment and protec-
tion systems intended for use in potentially ex-
plosive atmospheres.
2014/35/EU
LVD
Directive of the European Parliament and of the
Council on the harmonisation of the Laws of the
Member States relating to the making available of
electrical equipment designed for the use within

The applied standards can be found in the EU Declaration of Conformity
for the device.
2.11 Use in potentially explosive areas
WARNING
Unsuitable device for potentially explosive areas
Risk of explosion!
► Use only devices that are approved for use in Ex-zones and are
marked accordingly.
► Make sure that the device is suitable for the area of use.
WARNING
Loss of safety of the device in the ignition protection class Intrinsic
Safety "Ex i"
If the device has already been operated on non-intrinsically safe circuits
or with a higher operating voltage, the safety of the device for use in po-
tentially explosive areas is no longer guaranteed. There is a danger of
explosion!
► Connect the device in the ignition protection class Intrinsic Safety ex-
clusively to an intrinsically safe electrical circuit.
► Observe the electrical data in the certificate.

ARCA Regler GmbH 2 Safety
Series 827S.E/X 11 / 4209.2019 / 1.0
WARNING
Impermissible accessories and impermissible spare parts
Danger of explosion in potentially explosive areas or damage to the
device!
► Use exclusively original accessories and original spare parts.
► Observe all relevant installation and safety instructions described in
the manuals for the device, accessories and spare parts.
WARNING
Open cable entry or incorrect cable gland
Danger of explosion in potentially explosive areas or damage to the
device!
► Seal the cable entries for the electrical connections. Use exclusively
cable glands or blanking plugs for this that are approved for the re-
spective ignition protection class.
WARNING
Exceeding the maximum ambient or media temperature
Risk of explosion in potentially explosive areas
The temperature class of the device is no longer valid if the maximum
permissible ambient or media temperature is exceeded!
► Make sure that the maximum permissible ambient or media temper-
ature of the device is not exceeded.
WARNING
Electrostatic charging of nameplates
The nameplates used on the device can reach a charging capacity of 5
pF.
► Keep the device and the cables at a distance from strong electro-
magnetic fields.
CAUTION
Electrostatically endangered assemblies
The device contains electrostatically endangered assemblies. Electro-
statically endangered assemblies can be destroyed by voltages far be-
low the threshold of human perception. These voltages already occur if
you touch a component or electrical connection without having electro-
statically discharged yourself first. The damage caused to an assembly
due to overvoltage is not usually immediately apparent and only be-
comes noticeable after a lengthy period of operation.
► Therefore, prevent electrostatic charging.

Series 827S.E/X 15 / 4209.2019 / 1.0
6 Description
6.1 Function
▪ The signal box 827S is used for the feedback of up to 3 freely ad-
justable valve positions (positions of the actuator) to the control sys-
tem. The stroke or rotary movement of the actuator is transmitted to
a shaft by the stroke or rotary angle sensor. This rotary movement is
transmitted directly to an immersion disc. The movement of the im-
mersion disc into or out of the respective slot-type initiator generates
the corresponding electrical signal.
▪ The slot-type initiators can be arranged in arbitrary positions around
this immersion disc and adjusted so that almost any desired switch-
ing position is representable for the slot-type initiator.
6.2 Construction
This section describes the mechanical and electrical construction, the
device components and the principles of the operation of the signal box.
The signal box is used to signal the positions (usually the end positions)
of:
▪ linear actuators or
▪ rotary actuators VDI/VDE 3845
Linear actuators may be mounted in a number of ways.
▪ NAMUR or IEC 60534
▪ integrated mounting (ARCA, SAMSON)
The signal box can be mounted and operated on all normal actuators.
The device is available for single-acting and double-acting actuators as
well as for potentially explosive and non-potentially explosive applica-
tions.

7.1 Safety instructions for assembly
CAUTION
Improper installation
Improper installation can result in damage to the device, its destruction
or the impairment of its function.
Ascertain that the device shows no visible signs of damage each time
before installing it.
Ascertain that the process connections are clean and that suitable seals
and cable glands are used.
Install the device using suitable tools.
ATTENTION
The device protection class becoming null and void
Damage to the device due to open or improperly closed housing. The
protection class specified on the nameplate is no longer guaranteed.
CAUTION
Humid environment
If the environment is humid, mount the signal box in such a way that
there is no chance of the shaft freezing at low ambient temperatures.
Make sure that water does not enter an open housing or screw connec-
tion. If the signal box cannot be immediately and permanently mounted
and connected on site, it is possible for water to enter.

certainty with regard to the actual working stroke (pneumatic actuat-
ors often have a setting distance reserve), the next larger scale value
should be selected. The centre of the pin should rest on the scale
line on the lever (2).
