2.1 Explosion protection: pressurized enclosure
The use of pressurized enclosures allows the operation of ‘non explosion protected’ devices in
hazardous areas inside zone 1 or zone 2 area. The protection type ‘pressurisation’ is based on
the principle of maintaining a constant pressure using air or a protective gas to prevent an explosive mixture forming near the device inside the pressurized enclosure.
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.

2.2 Pressurized enclosure system F860S
The pressurized enclosure system F860S contains at least the control unit FS860S and a solenoid valve or ventilator. Each can be mounted in- or outside the enclosure. For the air supply due
to the necessary amount of air (throughput quantities of up to 120 m³/h) the employment of fans
is recommended. The point of sucking air in of these must take place in the safe area!
Furthermore, an operator panel is available for remote control. It is also possible to connect intrinsically safe peripherals (e.g. temperature, pressure sensors, switches) to the control unit
FS860S.
The pressurized enclosure system F860S can be configured in two different modes: Pressurization with leakage compensation and pressurization with continuous flow of protective gas.
2.2.1 Mode pressurization with leakage compensation
After purging, the control unit FS860S holds the pressure inside the enclosure at a minimum of
0,8 mbar (80 Pa). Two different solenoid vale techniques are available: digital working solenoid
valve (SVD) technique or proportional working solenoid valve (SVP) technique.
a) Digital solenoid valve technique
While purging, the SVD is activated and a large amount of purge medium flows into the enclosure
through a nozzle with a large cross section. After purging, the control unit turns off the SVD.

F860S
2 Introduction: Pressurized enclosure system F860S
Page 6
The leakage compensation is done by a bypass choke, with a very small adjustable cross section
(diameter 12 mil (0.3 mm) up to 40 mil (1 mm), inside the valve. The protective medium flowing
into the enclosure is adequate to maintain a pressure of at least 0,8 mbar (80 Pa). The pressure
is monitored by the control unit FS860S by a proportional working pressure sensor. The maximum and minimum pressure of the enclosure is programmable within the configuration menu.
If leakage losses grow up (e.g. by aging of cabinet’s seals) and cannot be
compensated by the bypass, the enclosure will be shut down!
For purging, a conventional (time based) as well as an improved integrating purging method (integration of real flow) are available:
1. Using the conventional method, the purge quantity is based on the product of a monitored
minimum flow rate at the enclosure outlet and time. The flow rate depends on the size of
the valve’s nozzle (diameter 40 mil (1 mm) ... 320 mil (8 mm)) and prepressure. This has to
be calculated using a formula or a pressure-nozzle diagram.
The conventional purging method using a digital valve has a considerable disadvantage:
During purging phase and also while normal operation, a constant rate of protective gas is
needed. For getting system availability, the inflow rate has to be selected bigger than the
leakage losses of the enclosure.

2. Using the improved integrating purging method, the FS860S unit measures the real flow
rate at the enclosure outlet and integrates the signal to get the real purged volume. Additionally, a minimum flow rate is monitored to ensure a safe purging phase. If the flow rate
sinks below the minimum, the integration will be stopped and continues automatically by
rising above the minimum.
Increased inflow volume into the cabinet automatically leads to a shortening
of time for purging when using the integrating purge method.
This fast and efficient purge method enables shortest start-up times!
b) Improved proportional solenoid valve technique
The internal proportional working pressure sensors also allow the use of a proportional solenoid
inlet valve. This valve is used as the actuator of a digital-working FS860S PID-control loop for the
inner pressure of the cabinet.
The benefits of pressure feedback control are:
1. Dramatically decreased consumption of purge gas.
2. Increased availability of the application, based on constant pressure inside Ex-p-housing;
higher leakages e.g. by aging of gaskets etc. will be compensated.
Æ Adaptive compensation of leakage losses of the Ex p encapsulation!
3. Minimization of streaming noise.
4. Easy adjustment of pressure levels to specifications of Ex-certificate.
Further advantages are:
1. Exact regulation of pressure also during purging phase.
2. Due to defined pressure inside cabinet, pressure sensible parts like foil keyboards, windows etc. will not be damaged.
Increased system availability by PID controlled cabinet pressure!
Pressure sensitive parts (e.g. windows, front foils) will be protected.
2.2.2 Mode pressurization using continuous flow
The control unit FS860S also supports the operation mode „continuous flow“. This operation
mode is used, for so called “containment systems”, where flammable gases or liquids will be
emitted into the inner of the cabinet during normal operation (e.g. at analysers).
After the purging phase, a continuous, PID controlled flow rate will be kept during normal operation. This continuous flow rate is used for dilution flammable gases or vapours below their “lower
explosion concentration”.
As during integrating purging method, an adjustable minimum flow rate will be monitored additionally.

2.3 Peripherals
2.3.1 Operator panel BT851
For the control unit FS860S an optional operator panels for remote control and visualization is
available. The panel is based on the explosion protection class 'intrinsically safety' and offers an
improved operator access when the FS860S control unit is mounted inside the cabinet.
The operator panel BT851 indicates operation and malfunction status as plain text via LC-display.
Four front-sided push-buttons offer total command of the FS860S unit. Status, momentary pressure, flow rate as well as remaining purge volume/time are available. The connection to the control unit is based on serial communication, using only 3 wires (max. distance 20m).
2.3.2 Disconnector unit SR852 and SR853
According to EN 50016 all non- intrinsically safe connections of the ignition capable apparatus
must be disconnected, if the protection gas pressure falls below the safety limit.
In many applications more than the two connector terminals on the control unit FS860S are
needed. In these cases the disconnector unit SR 852, with 8 or opotional 16 galvanically separated connectors (switching power 250V, 5A) is available.
The S853 provides 4 galvanically separated channels with a switching power of 400V, 16 A,
separates 4 channels. It can be used e.g. to switch of 3 phase networks.
2.4 Conformity with standards
The explosion proof device Fehler! Unbekannter Name für Dokument-Eigenschaft. meets requirements of listed standards in the attachment (Declaration of conformity). They were developed, manufactured and tested in accordance with state-of-the-art engineering practice and
ISO9001:2008.

3 Installing the unit/ Getting started
This chapter contains important steps for mounting, connecting and starting.
3.1 Requirements to the cabinet
The cabinet must meet at least protection class IP54.
The system F860S is suitable only for housings with a
volume of more than 1000 liters.
For smaller housings the overpressure system F850S is to be used.
3.2 Mounting
3.2.1 Control unit FS860S
The control unit FS860S can be placed directly inside hazardous area. The location (inside or
outside the enclosure) as well as the position is variable and can be fitted to customers specific
requirements. If possible, arrange the in- and outlet of the control unit on a horizontal axis. See
also Figure 15 in the Appendix.
The control unit can be fitted to the cabinet or to a mounting plate using the 4 integrated, rear
sided fixing points. In most applications, a fixing with the 2 inch screw connection of inlet or outlet
is sufficient.
The in and Outlet of the FS860S should be arranged on
an horizontal axis.
Watch local safety guidelines and EN60 079-14
The solenoid inlet valve(s) should be mounted as far
away from the control unit FS860S as possible, to
achieve safe purging! (E.g. diagonal arrangement, see
Figure 15).
If a pipe work system must be attached to the inlet or
discharge opening of the control unit FS860S, it is important that the inside diameter is bigger than the orifice
plate diameter x 1,5 at least.
Further the pipes should be kept as short as possible.

3.2.2 Solenoid valves
Mounting position of solenoid valve is free. It can be mounted inside or outside the cabinet. For
mounting hints, see additional manufacturer's guide of solenoid valve.
The proportional SVP.12 valve is medium supported and
must contain a nozzle with 8 mm diameter at the output.
The compressed air supply must ensure a pressure of 23 bar directly at the valve. This pressure must be delivered constantly also at a flow rate of 1200 liters per minute!
3.2.3 Operator panel BT851
The operator panel BT851.0 can be integrated directly into the enclosures outer skin. The
BT851.5 has a separate housing for mounting on a plate or wall. For location and drill sizes see
Figure 13 Dimensions and templates of BT851 are shown in the annex.
3.2.4 Disconnector units SR852 and SR853
The disconnector units SR852 and SR853 can be mounted and operate in hazardous area zone
1. They use integrated Ex-e terminal boxes and clamps.
3.3 Connecting and Commissioning
After mounting the FS860S, connect the power supply lines, the valve lines and other non- intrinsically safe lines to the terminals 11-24 into the explosion proof enclosure of the control unit
FS860S.

3.3.1 Connection details
HIGH VOLTAGE!
Beware of high voltages and currents when handling this device or power
lines!
Electric shocks can injure or kill!
Ensure your installation is compliant to the following: EN60 079-14, certification and description documents of FS860S.
Do not exceed terminal safety limits of each terminal.
See limits in technical details or declarations of conformity.
If an external key switch is used for enabling the bypass function, it can be
helpful to set the bypass code at the FS860S to 9999 to prevent a secondary
bypass function by bypass code from the control unit.
The external key switch for the bypass function has to be connected to terminals 4 and 5 of the FS860S.
It is possible to switch on and off the internal devices of the cabinet using the
On/Off key at the FS860S control unit or at the BT851 operator panel. If this
function should not be used, it is possible to short cut terminals 4 and 6 of the
FS860S, to enable an automatic power on after purging phase.
In this case, the On/Off-buttons at the control unit FS860S and BT851 are disabled.

3.3.3 Power off relays
The maximum current limits (5 A) on the clamps
11,12 and 13,14 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!!

3.3.6 Automatic Purging process
The control unit FS860S starts the purging process immediately after start up, if the minimum
pressure of 0,8 mbar (80 Pa) can be built up inside Ex p cabinet.
Minimum pressure and minimum flow rate will be monitored simultaneously to ensure a safe
purging process.
If the purging flow rate drops below its minimum (e.g. temporary interrupt of air supply or temporary shut of the outlet), the purging process will be interrupted and the control unit continues
purging, after the disturbance is removed. If purging pressure exceeds the min or max limits, the
purging process will be terminated and the control unit will restart with a new purging process
automatically after achieving purging conditions.
The table below shows the minimum flow rate in accordance of the used orifice plate.

3.4 Maintenance
Depending on the cleanness of the used purging gas, the pneumatic inlet and outlet parts of the
FS860S as well as the solenoid valve have to be checked regularly for pollution by e.g. oil, dust,
etc. or corrosion to ensure a safe work of the application.

4.3 How to enter and leave the bypass mode
Only for maintenance of the cabinet!
Set bypass only if no hazardous atmosphere is present inside or
around the cabinet!
The bypass mode is denied, if it is possible that an explosive atmosphere can arise inside the Ex p- cabinet! (e.g. at containments systems)
It is possible to enter bypass mode in each operation sate of the control unit.
The origin state is normal operation.
Press „Up“-button
By-CODE
Enter the bypass code using the “up”, “down” and “shift right” button.
The ex works bypass code is ‘0002’.
0002
Confirm the right bypass code using the ENTER- key.
Bypass
The bypass mode is now active.
Or
If the control unit is set to “automatic on” the display toggles between “bypass” and “On” and the relay contacts (Terminals 11,12 and 13,14) are
closed.
On
Leaving of bypass mode is done by the same procedure.
If the bypass was activated in normal operation (leakage
compensation), the FS860S remains in bypass mode until it reaches the set point pressure inside the cabinet in
10 seconds.
Alternative to the use of the push buttons, the bypass mode can be called by using a key switch
between intrinsically safe terminals 4 and 5.

4.4 Information during normal operation
The FS860S can give several information to the user during different sates of operation via the
LC-display.
You can choose between the following information items: state, current pressure-, flow rate-, or
remaining purge time- indication using the “down/INFO”- button (see figure below).
