1.2 Safety Guidelines for explosion proofed devices
Application and Standards
This instruction manual applies to explosion protected control panels of type of protection types below. This apparatus is only to be used as defined and meets requirements of EN 60 079 particularly EN60 079-14 "electrical apparatus for potentiality explosive atmospheres". It can be used 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 the respective nationally valid regulations and requirements are to be observed.
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 nonintrinsically 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.
The control panel has to have a back-up fuse as stipulated. The mains connection must have a sufficient short circuit current to ensure safe breaking of the fuse. 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.

2 Introduction: Pressurized enclosure system F 850S
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 and zone 2. 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 according EN50016, second release (5/1996)
According EN50016 second release from May 1996 is only those pressurized enclosure system allowed, which is safety examined according EN 954-1.
The FS 850 S reaches the category 3 according EN 954-1 [4] (single fault evaluation). That means that a single arbitrary fault can occur without losing the safety functionality.
2.3 Pressurized enclosure system F 850S
The pressurized enclosure system F 850S contains at least the control unit FS 850S and a solenoid valve. Each can be mounted in- or outside the enclosure. Furthermore several remote controls (operation panels) are available to improve ease of operation. It is also possible to connect intrinsically safe sensors to the control unit FS 850S.
The pressurized enclosure system F 850S operates in two different modes: Pressurization using leakage compensation and Pressurization using continuous flow of protective gas.
2.3.1 Mode pressurization using leakage compensation
After purging, the control unit FS 850S holds the pressure inside the enclosure at a minimum of
0,8 mbar. Two different solenoid vale techniques are available: digital working solenoid valve
(DSV) technique or proportional working solenoid valve (PSV) technique. a) Digital solenoid valve technique
While purging, the DSV is activated and a large amount of purge medium flows inside the enclosure through a nozzle with a large cross-section. After purging, the control unit turns off the DSV.
The leakage compensation is made by a bypass choke, with a very small adjustable crosssection (diameter 0,3 ...1 mm), inside the valve. The protective medium that flows into the enclosure now is adequate to maintain a pressure of at least 0,8 mbar. The pressure is monitored by the control unit FS 850S. The maximum and minimum pressure of the enclosure is programmable.
For purging, a traditional and a new integrating method are available:
1. Using the traditional method the purge quantity is a product of a pre-set minimum of flow rate and time. The flow rate depends on the size of the internal nozzle (diameter 1 ...6 mm) of the valve and can be specified by matched charts. The common rule of purging must be considered: let in minus leakage loss is bigger than flow minimum. This purging method is called as time based purging method.
2. In contrast to the traditional one the integrating purging method measures the real volume flow through the enclosure outlet and adds it up to get the real purge volume. Also, the flow rate is monitored, depending on the size of the plate orifice of the control unit. If the flow rate sinks below its minimum, it will be ignored and it will not contribute to volume integration. Therefore we achieve a safe and economical purging method. See also Figure_1.

F 850S 2 Introduction: Pressurized enclosure system F 850S
Pressure inside the enclosure will be observed by each purging method.
Page 6
The digital solenoid valve technique has a considerable disadvantage: during purging process and normal operation, a constant rate of protective gas is needed. For safety reasons the rate must be larger than leakage rate of the enclosure. Wasting protective gas causes high costs in many applications.
Figure 1: Consumption of protective gas b) Proportional solenoid valve technique
Using proportional solenoid valve technique prevents unnecessary wasting protective gas. The internal proportional working sensory equipment and a proportional valve as actuator are combined to a pressure feedback control system.
The benefits of pressure feedback control are:
1. Considerable less consumption of protective gas - additional costs for proportional valve will be amortised soon
2. Increased service reliability achieved by constant pressure inside enclosure - increasing leakage caused by e.g. ageing of the enclosure will be balanced and sudden failure is prevented
3. Almost no flow noise and only a small protective gas consumption using a solid enclosure
Another advantage using a proportional solenoid valve is; that pressure control is also used during purging. A set-point pressure will be achieved in the enclosure, while the flow volume, that leaves the enclosure, will be recorded and integrated through time, until the required purge volume is achieved. Advantages of this method are:
1. A definite pressure while purging - pressure sensitive parts of the enclosure, like membrane switch panels or windows, will not be overloaded.
2. Purge volume accuracy is achieved by integration of the purge medium flow volume at the outlet. Wasting purge medium is no more a topic of today.
2.3.2 Mode pressurization using Continuous flow
The control unit FS 850S incorporates the operation mode „continuous flow“. This operation mode is necessary, for example if an analyser produces an explosive atmosphere inside the enclosure (containment system). The operation mode continuous flow flushes the enclosure permanently. After the (pre-) purging procedure (purging process) a set-point flow rate is adjusted during normal operation. The monitored flow rate minimum is adjustable. The continuous flow operation mode can be realised using 2 digital solenoid valves as well as using one proportional solenoid valve.

F 850S 2 Introduction: Pressurized enclosure system F 850S Page 7
2.3.3 F 850S -Application using „Containment Systems“
„Containment Systems“ are defined as parts of a device within a pressurized enclosure, which could emit combustible gas (or occasionally an explosive environment: zone 1, explosive mixture) from within the enclosure.
In order to receive an EEx p-System including a „Containment System“, which is failsafe according EN 50016, with the attribute 'no emission', the following conditions must be met:
1. The flammable substance inside the containment system is in the gas or vapour phase when operating between the specified temperature limits
2. The minimum pressure specified for pressurized enclosure is at least 50 Pa higher than the maximum pressure specified for the containment system
3. An automatic safety device initiates, if the pressure difference falls below 50 Pa.
This automatic safety device can be activated by a difference pressure switch, looped into the external alarm loop (terminal 4/10 on FS 850S). If an alarm occurs on this loop, the control device
FS 850S will turn off the ignition-capable device immediately. After alarm cancelling the control device FS 850S starts operation automatically with the purging procedure. The external alarm loop is made by a normal closed connection method.
2.4 Peripherals
2.4.1 Operating panels
For the control unit FS 850S several operating and visualising panels are available. These panels consist of the explosion protection class 'intrinsically safe' and are considerably advantageous, particularly when the control unit is mounted inside the enclosure.
1. Common operating panels: BT 854.1 and BT 855.1 with
• On/Off-Switch
• Key-operated switch for bypass
• LED-indicator for READY and ON
The connection to the control unit consists of 6 wires.
2. Intelligent operating panel type BT 851
This operation panel indicates operation and malfunction reports as plain text. The 4 membrane switches offer total command of the control unit. Status, momentary pressure, flow rate as well as remaining purge time are always available.
The connection to the control unit consists of only 3 wires.
2.4.2 Disconnector unit SR852 and SR853
According to EN 50016 all non- intrinsically safe connections of the ignition capable apparatus must be disconnect, if the protection gas pressure falls below the safety limit. In many applications more than the two connector terminals on the control unit FS 850S are needed. In these cases the disconnector unit SR 852, with 8 respectively 16 galvanically separated connectors, is considerable helpful.
The S853 provides a switching power of 250V , 16 A.

3 Installation and connection
This Chapter contains important steps for mounting, connecting and starting.
3.1 Mounting
3.1.1 Control unit FS 850S
The control unit FS 850S can be placed inside a hazardous area. The location (inside or outside the enclosure) as well as the position is almost arbitrary. Only intake and outlet of the control unit
should be lined up on a horizontal axis. See also Figure 12 in the Appendix.
The control unit has 4 holes on the rear plate for mounting, although fixing only with the screw connection of intake or outlet is sufficient.
The solenoid valve(s) and the control unit (respectively pressure monitor) should be mounted on the enclosure as far away from each other as possible (E.g. space diagonal arrangement), to achieve a total purging.
Observe local safety guidelines and the regulative DIN
EN 60079-14.
3.1.2 Solenoid valves
The solenoid valves can be mounted inside or outside the enclosure. For mounting position see manufacturer's guide.
3.1.3 Operating panels BT 8xx.x
° Operating panel BT 851.0
The Operating panel BT 851.0 is mounted, without rear plate, directly on the enclosure. For mounting and bushing of the wire, several holes must be made. For location and drill size see
Figure 13: Dimensions and template BT 851in appendix.
° Operating panel BT 851.5
The operating panel BT 851.5 has housing with environment protection IP 65. It can be located
anywhere in hazardous area zone 1. For location and drill size see Figure 13: Dimensions and
template in appendix.
° Operating panel BT 814.x
The operating manual BT 814.x consists only of 2 LEDs and an ON/OFF-switch, directly fixed on the enclosure. The BT 814.1 has an additional key-operated switch for bypass. For location and
drill size see Figure 14: Dimensions BT 855, template BT 854 in appendix.
° Operating panel BT 815.x
The operating panel BT 815.5 has housing with environment protection IP 65. It can be located
anywhere in hazardous area zone 1. For location and drill size see Figure 14: Dimensions BT
855, template BT 854 in appendix.
3.1.4 Disconnector unit SR 852
The disconnector unit SR 852 can be mounted and operated in hazardous area zone 1. It represents an Ex-e terminal box.

3.2 Connecting and Commissioning
After mounting, connect the 'intrinsically safe' peripherals to terminal 1-10, and the power supply, valves and ignition-capable apparatus to increased safety terminals of the control unit.
LINE VOLTAGE !
Extreme caution is advised when handling this device.
High electrical discharge is possible and can be fatal.
Please note the following Standard of Compliance:
DMT 99 ATEX E 003 and the regulative DIN EN 60079-14.
Do not exceed terminal safety limits of each terminal.
See limits in technical details or declarations of conformity.
Figure 2: Blockdiagram FS850S
If the BT854.1 or BT855.1 operator panel is being used, the bypass function can be activated via an external key switch. In this case set the bypass code to 9999 to prevent a secondary bypass function by bypass code directly from the control unit. The key switch is to be connected to terminals 4 and 5 of the control unit.
If external operation panels BT 81x or additional pressure monitor are not used, it is possible to connect terminal 4 and 6 of the control unit FS 850S to a shorting bridge, to enable an automatic switch after purging process.
In this case, the On/Off-function of the far left button on the control unit FS
850S is non- operational.

3.2.4 Purging process
The control unit FS 850S starts the purging process immediately after start up, providing the programmed minimal pressure (minimum 0.8 mbar) is present. Parallel to pressure monitoring, the flow rate will be watched, to get a safe purging process.
If the purging flow rate passes its minimum (e.g. temporary shut at the outlet), then the purging process will be interrupted and the control unit continues purging, after the disturbance is gone.
But if purging pressure exceeds the min or max limits then the purging process will be terminated and the control unit will start a new purging process automatically after achieving purging condition.
The table below shows the minimum flow rate in accordance of the used plate orifice.

3.3 Maintenance
Depending upon purity of the assigned purging air the inlet and outlet opening of the FS850S must regularly on impurities (e.g. oil, dust, etc) or corrosion to be examined. In case of serious impurities the operator should weigh the possibility of a punctual appropriate cleaning by Gönnheimer Elektronic GmbH in relation to a spontaneous loss of the controller.
3.4 Repairs
