Operation instruction for Explosion protected device
Application and Standards
This instruction manual applies to explosion-protected devices of types below. This apparatus
is only to be used as defined and meets requirements of IEC/EN 60 079 particularly IEC/EN60
079-14 "electrical apparatus for potentiality explosive atmospheres".
Use this manual in hazardous locations, which are hazardous due to gases and vapours according to the explosion group and temperature class as stipulated on the type label. When
installing and operating the explosion protected distribution and control panels you should
observe the respective nationally valid regulations and requirements.
General Instructions
Work on electrical installations and apparatus in operation is generally forbidden in hazardous
locations, with the exception of intrinsically safe circuits. In special cases work can be done on
non-intrinsically safe circuits, on the condition that during the duration of such work no explosive atmosphere exists.
Only explosion protected certified measuring instruments may be used to ensure that the apparatus is voltage-free. Grounding and short-circuiting may only be carried out, if there is no
explosion hazard at the grounding or short circuit connection.
To achieve an impeccable and safety device operation, please take care for adept transportation, storage and mounting, as well as accurate service and maintenance. Operation of this
device should only be implemented by authorised persons and in strict accordance with local
safety standards.
The electrical data on the type label and if applicable, the "special conditions" of the test certificates BVS 15 ATEX E 048 X and IECEx BVS 15.0037 X are to be observed.
For outdoor installation it is recommended to protect the explosion protected distribution and
control panel against direct climatic influence, e.g. with a protective roof. The maximum ambient temperature is 40°C, if not stipulated otherwise.
Terminal compartment in Increased Safety
When closing, it is to be ensured that the gaskets of the terminal compartment remain effective, thus maintaining degree of protection IP 54 according to IEC/EN 60529. Close unused entries by impact-proof stopping plugs, which are secured against self-loosening and turning.
Maintenance Work
The gaskets of Ex e enclosures are to be checked for damages and replaced, if required. Terminals, especially in the Ex e chamber are to be tightened. Possible changes in colour point to
increased temperature. Cable glands, stopping plugs and flanges are to be tested for tightness
and secure fitting.
Intrinsically Safe Circuits
Erection instructions in the testing certificates of intrinsically safe apparatus are to be observed. The electrical safety values stipulated on the type label must not be exceeded in the
intrinsically safe circuit. When interconnecting intrinsically safe circuits it is to be tested,
whether a voltage and/or current addition occurs. The intrinsic safety of interconnected circuits is to be ensured. (IEC/EN 60079-14, section 12)

General requirements to pressurized enclosure system
F840
The pressurized enclosure control device (FS840) can be combined with every Ex pzc- housing
that full fills the following requirements.
2.1
2.2
General requirements
1
The Ex pzc- system must be inspected by a skilled person of accordance to
IEC/EN 60079 –2, IEC/EN 60079 –14 and this manual.
2
Mount the solenoid valve (purging medium input) and control unit FS840 to an
maximum of distance (optimal arrangement is diagonal)
3
The operator must not do any technical changes to the control unit FS840. Any
change will invalidate the conformity statement BVS 15 ATEX E 048 X and IECEx
BVS 15.0037 X.
4
Any maintenance activities has to be done by Gönnheimer Elektronic GmbH
5
Corrupt Ex p- pipe connections have to be repaired immediately
6
The introduction of flammable gas into the Ex pzc- housing, e.g. for gas analyser
application, is prohibited.
Mechanical requirements to the Ex pzc- housing
1
Regard particularly IEC/EN 60079-2, section 7
2
The Ex pzc- housing must hold the 1,5 – fold of the maximum pressure, which
can be reached inside of the cabinet, 2 mbar at least. The operator has to define
the maximum pressure of the housing and has to program this pressure value as
monitored max. pressure into the FS840.
3
The Ex pzc- housing must pass a impact test according IEC/EN 50021 Table 13
4
The protection class of the Ex pzc- housing must be greater than IP40.
5
Cable glands must have a protection class greater than IP54.
6
If the Ex pzc- housing has surface made of synthetics (e.g. windows) with an area greater than 100 cm², than a warning sign against electro static discharge is
necessary.
Caution ! Danger of static discharge. Clean only with humid cloth!
7
There is no danger of static discharge, if the synthetic surface has a thickness of
≤ 0,2 mm (Group IIC) respectively 2 mm (Group IIB) or less and it is mounted on
a metallic ground.
8
If the Ex pzc- housing posses internal compartments the installer has to obey the
following rules:
a) Components with a free internal volume less than 20 cm³ are not considered
to be internal compartments requiring purging as long as the total volume of all
such components is not more than 1% of the free internal volume of the pressurized apparatus. (IEC/EN 60079 – 2; Abs. 5.5.4)
b) Provide not less than 1 cm² of vent area for each 1000 cm³, with a minimum
vent size of 6,3 mm diameter should be allow for adequate purging. (IEC/EN
60079 – 2; Abs. 5.5.2)

c) Place the vents in a diagonal order, as shown on the picture below, with a
minimum vent size of 6,3 mm diameter
d) Installer can also remove covers or doors of internal housings if they provide
adequate vent diameters alternatively.
e) If the topics above are not applicable, a separate piping must be added to the
internal compartment. The purge medium flow through the compartment must
be high enough to make sure that the air in the compartment is exchanged at
least 10 times higher. For instance:
2.3
Determination of pre- purging period
If its not sure, at power up, that the atmosphere inside of the enclosure and the appropriate pipes
is below 25% of the lower explosive limit (LEL) (IEC/EN 60079 – 14 chapter 13.4), a prepurging of
the pressurized enclosure is necessary.
The pre purging of the housing is prohibited, by an Ex pD system (pressurized enclosure in zone
22).

Purge medium requirements
1
The purging medium must not be derived from hazardous area, it must be contamination free ( dry, free of oil and dust)
2
The temperature of the purge medium should not exceed 40°C.
3
If another purge medium than air is used, it is important to regard the minimum
oxygen content of the ambient. Maybe it is necessary to install a exhaust pipe
from the FS840 to out-of-door.
4
The inlet and the outlet of the purging gas should be located as far away to each
other as possible.
5
The pressure lost an the solenoid valve (PValve) must not be higher than 500
mbar, while pre- purging.
Temperature class of the Ex pzc- housing
The installer has to define the maximum ambient temperature and the resulting maximum temperature class of the Ex pzc- housing.
To determine the temperature class, measure, on worst conditions, the hottest point on the surface of the Ex pzc- housing and recalculate it to the maximum ambient temperature. The minimum
temperature class is the one of the FS840 and its surface temperature.
If some parts inside of the housing get hotter than the temperature class, the installer has to determine the time in which the temperature of those parts falls below the temperature class. He has
to place a sign on the Ex pzc- housing with the following sentence:
Power off the apparatus and wait for x minutes for cool down !
X is the determinate time multiplied with a safety factor 1,5.
2.6
Particular requirements in zone 22 (Dust hazardous area)
2.6.1 Pre purging / cleaning of the housing
For the employment in the zone 22 the FS840 must not initialize a pre purging phase. Therefore,
the automatic purging at the controller FS840 has to be deactivated.
The purging phase before the start-up of the inserted, electrical non-ex operational funds, upstream within the gas ex range, is replaced in the zone 22 by inside cleaning the housing.
2.6.2 Markings on the housing
On the housing has to be the following markings:
„WARNING: REMOVE ALL DUST FROM THE INSIDE OF THE ENCLOSURE BEFORE
CONNECTING OR RESTORING THE ELECTRICAL SUPPLY“
On ex p-housings for zone 22 with doors without tools to be opened, must the following reference
be attached:
„WARNING: DO NOT OPEN WHILE ENERGIZED UNLESS IT IS OBVIOUS THAT NO
COMBUSTIBLE DUST IS PRESENT“

2.6.3 Special conditions in the manual of the Ex pD of system (Zone 22)
In the manual for Ex pD applications for the zone 22 the following items are supplemented:
The use of the Ex pD application within the zone 22 must take place without pre purging period
phase. The automatic flushing at the controller FS840 is to be therefore always deactivated.
The system may be operated not with a single solenoid valve, but only with a leakage balance
mechanism without flushing attitude.
Before start-up of the ignition capable apparatus, the inside of the housing is to be cleaned completely.
The protective class of the Ex pD housing in dust explosive area with not leading-capable dust
has to be at least to IP5X, with leading-capable dust at least IP6X.

Introduction: simplified pressurized enclosure system
The use of simplified pressurized enclosures allows the operation of ‘non explosion protected’
devices in hazardous areas inside zone 2. The protection type ‘pressurization’ is based on the
principle of maintaining a constant pressure using air or a protective gas to prevent an explosive
mixture forming near the apparatus inside the pressurized enclosure.
Generally, before start-up, the pressurized enclosure must be purged with air or protective gas to
remove any explosive mixture that may be inside the enclosure. This automatic procedure is
called purging process.
If the operator is sure, that the atmosphere inside of the enclosure and the appropriate pipe infrastructure and the ambient of the enclosure is below 25% of the lower explosive limit (LEL) (IECEN
60079 – 14 chapter 13.4), the pre purge phase can be cancelled. The operator has the responsibility to ensure the non existence of Ex atmosphere every time by energizing the Ex pzc- system.
An simplified pressurized enclosure system consists of two components and the enclosure.
1.
Control unit FS840 for process control and monitoring
2.
Solenoid valve SVD.L.x or a sinter metal throttle SD840 to control air input fed by
pressured air network
See chapter 2 for general requirements of pressurized enclosure and integrated ignition capable
apparatus.
3.1
Pressurized enclosure system F840
The device FS840 is the control device of a F840 - pressurized enclosure system.
The control device FS840 provides all necessary functions to install a pressurized enclosure system according IEC/EN 60079-14 section 13, and. IEC/EN 60079-2 „pzc“. The FS840 measures the
internal pressure and alarms or powers off, if the pre- defined minimum pressure is reached. The
FS840 can also pre purge the housing before automatic powering on the housing. In this case
connect a digital working 2/2 way solenoid valve to the appropriate terminals. The solenoid must
have a separate certification for zone 2.

Pre- operation phase
3.2.1 Pressurized enclosure system without pre- purging
If the operator is sure, that the atmosphere inside of the enclosure and the appropriate pipe infrastructure is below 25% of the lower explosive limit (LEL) (IEC/EN 60079 – 14 chapter 13.4) at power up, he can abandon the pre purging of the enclosure in zone 2. In that case the FS840 monitors
only the pressure inside of the enclosure on 0.8 mbar at minimum and maximal 22.0 at maximum.
If any limit is exceed, the FS840 changes the state on relay(s) output(s).
The purge medium flows through an adjustable sinter metal throttle into the housing while reducing its pressure (see block diagram). The FS840 has an mechanical output valve which opens at
approximately 5 mbar to let the purge medium out. Before this valve is a spark lattice located thus
the purge medium can be exhausted directly to the hazardous area.
3.2.2 Pressurized enclosure system with pre- purging
To pre- purge the housing connect a digital working 2/2 way solenoid valve (SVD.L) to the terminal 5 and 6 of the FS840. Also configure the pre- purging period into the structure menu of the
control device. After pre- purging the valve closes automatically and the adjustable throttle of the
SVD.L lets a small amount of purging medium into the housing to hold pressure.
The installer can determine the pre- purging time once by doing the attenuation test according
IEC/EN 50016 section 14.3.
As an alternative he can calculate the purging time without the elaborate attenuation test see below:
The purging time depends on minimum flow (Qmin), free internal volume (V) and the free volume of
the connected pipes (Va). Final the calculated time must be multiplied by 10. The purging time
tpurge is:
t purge =
10 × (V + Va)
Qmin
The minimum flow (Qmin) depends on the minimum pre pressure (Ppremin), the pressure lost at the
valve (PValve), internal pressure of the Ex pzc- housing (PInt) and the nozzle diameter (d). The pressure lost at the valve (PValve) should not exceed 500 mbar. The maximum internal pressure of the
housing is defined to be less than 20 mbar. The minimum flow Qmin can be calculated by:
Qmin =
2 × ( Ppre min − PValve − PInt )
ρ
×
d 2 ×π
4
ρ is the density of the purging medium. The density of air is ρ =1,2393 kg/m3, the density of nitrogen is 1,25 kg/m3. WE calculate the ρ of air for all gases, because the difference is only 3%.
The installer can calculate the purging time of ist own or he can use the automatic calculation in
the menu of the FS840 (see also section 5.6.1)

Operation mode “Leakage compensation”
The FS840 works after the pre purging phase or without pre purging phase immediately after the
voltage supply in the mode of operation "leakage compensation ".
In this mode of operation will maintain after an overpressure (at least 0.8 mbar) within the Ex p
cabinet. This cabinet minimum pressure as well as also a cabinet maximum pressure are programmable and are monitored constantly.
Leakage losses are compensated by a small bypass. This bypass is integrated in the valve and
mechanically adjustable (diameter 0.3... 1 mm).

4.1.1 Control device FS840
The control device FS840 is suitable for mounting in hazardous area zone 2. The installer can
place it in or outside of the Ex pzc- housing.
The installer can mount the control device using the 4 mounting holes in the housing rear, but the
fixing on the air in- or outlet is sufficient.
While mounting, observe local safety guidelines and
the regulative: IEC/EN 60079-14
The reference output (M5 screw on the left side of
the control unit) must have contact the ambient
pressure
If the control unit is built into the Ex pz- housing the reference output
must to connected to the ambient with a pipe or tube.
Additional see general requirement to pressurized
enclosure system in section 2 in this manual.
4.1.2 Spark barrier
The control unit has a spark barrier according to IEC/EN 60079-2. The exhaust air can be diverted
direct to Ex area.
4.1.3 Sinter metal throttle
While operation mode “leakage compensation” a small amount of purging gas enters through the
sinter metal throttle SD840 into the Ex p- housing to provide the desired overpressure. Dispensable purge gas will be exhausted (at an overpressure of 3-4 mbar) through the control unit FS850S
outlet valve.
4.1.4 Optional solenoid valve for purging
The installer can mount the solenoid valve in or outside of the Ex pzc housing, see details from

The control unit FS840 switches off the line voltage of the target device via the clamps 1,2 and 3,4.
The switching power is 250V / 5A.
The maximum current limits (5 A) on the clamps
28,29 and 30,31 should not be exceeded at any time!
E.G. By an application of switched power supply a multiple higher current as the nominal
max. current may occur. In this case a switching on current limitation (e.g., NTC) must be
added to avoid the off-limits high current.
If this is missed the risk of the „jammed relay contacts“ and within the loss of the explosion protection exists!!

Description, Explanation
Define the language shown on the
display of the FS840 in this menu
item. Available languages are: German, English, French, Dutch, Spanish
„Purg. Y.“ means that the Ex pzchousing will be pre purged before
“Ex Ok” Message is set
„Purg.N.“ means that the housing
will not be pre- purged. The “Ex Ok”
Message is set and the min. Pressure is monitored
Automatic purging time Yes:
The FS840 calculates the purging
time out of pre- pressure, nozzle
diameter
Automatic purging time No (=
Enter the purging time directly):
Define the function of output O1
(te. 1/2).
Explosion protection is ok:
The output is set, if the pressure is
higher than minimum.
Bypass- output: The output is high,
if the bypass is active
Purging- output: The output is high
as long the pre- purging procedure
is running
Signal pressure- output: the output
is high, if the actual pressure inside
of the Ex pzc- housing is below the
signal pressure level
Maximum pressure- output: the
output is high, if the actual pressure
inside of the Ex pzc- housing is
higher the maximum pressure level
Define the function of output O2
(te. 3/4). See functions O1 above
define the circuit-opening connection of output O1 (terminal (1/2)
no (= normal open)
nc (=normal closed)
define the circuit-opening connection of output O2 (terminal (3/4)
no (= normal open)
nc (=normal closed)
Purge time [h/min/sec]:
Enter the purge time directly. The
parameter only appears, if “automatic = no “ is chosen.
If „automatic = Yes“ the following
parameters will be asked:
• Purge volume [dm³]

• Pre- pressure [bar]:
pressure of the purge medium
pipe or pre pressure controller
• Internal nozzle diameter [mm]:
• Minimum pressure while prepurging [mbar]:
During pre- purging procedure the
FS840 monitors a increased
pressure inside of the Ex pzchousing to achieve the defined
flow on the output valve. This increased pressure is monitored
with this parameter (range = 7.0
mbar ... max. pressure)
Minimum pressure at normal operation [mbar]:
Monitored minimum pressure
Maximum pressure at normal operation [mbar]:
Monitored maximum pressure
Signal pressure at normal operation [mbar]
Menu code: Code word to start the
main menu. Ex works: “0001”
It is not possible to deactivate this
code with „0000“.
Bypass code: Code word to start
bypass mode.
The code can be disabled with
„0000“ . The sequence „9999“ disables the bypass in general
