Description of EEx p system F-361.C4 The EEx p pressurization system F-361.C4 serves to create and maintain an overpressure in an EEx p motor enclosure to prevent the ingress of the ambient(potentially explosive) atmosphere, according to EN 60079-2 / EN 50016. In addition a compensation for leakage losses is realized in a unique redundancy combination with a mechanical and an electronic controlled proportional valve. Motors with kind of Ex-protection EEx p can operate in combination with the EEx p system F-361.F4 in Ex areas 1 and 2 (according to DIN EN 60079-14). Combined with an enclosure which is suitable for use with overpressure the Ex protection class EEx p IIC T4 according to EN 60079-2 / EN50016 can be obtained. Standard ambient temperature for operation is -20 °C up to +55°C. Other temperature ranges are available on request.
Before commissioning please take note of the following points: 1. Clean the connected air pipe or tubing system of the installation plant to ensure
that the supplied air tube is free of dirt or small parts which will cause a malfunction of the purging system, if no air filter is used.
2. The internal volume of the motor enclosure must be purged with non-explosive compressed air, to reduce a possible explosive gas concentration to safety limits.
3. After purging the motor enclosure, an overpressure must be maintained inside the motor to prevent ambient air, which can contain explosive gas.
The overpressure inside the motor enclosure is continuously monitored.
If the pressure drops under the reference value an alarm signal is given and the motor has to be switched off automatically. The EEx p System F-361.C4 comprises the following components:
• control cabinet ST-200F/ST-200FM
consists of: main air valve for pressure supply, purge valve, proportional valve for operating pressure (leakage compensation), adjustment valves for purge- and leakage volume, measure points (to acquire leakage volume and the pressure inside the motor enclosure), indicator for purge pressure, EEx d junction box F900.041, EEx d box F-900.001, main switch, control unit F-351 (connected with terminals in junction box) for the signals "ready to start“, “motor not purged“, purging in progress", "purge sequence finished" and „motor shutdown“.
The control cabinet ST-200C/200CM monitors the air flow of the outlet valve and the pressure inside the motor enclosure. Simultaneous the control automatic works in accordance with EN 60079-2 / EN 50016 and ATEX 94/9. This monitoring system is a highly secure and redundancy controlling unit certified according to EN954-1 (security class Cat. 3).

• Outlet valve VA-100-3H
The outlet facility consists of a heavy duty case with built in pneumatic controlled valve and integrated spark arrestor and particle barrier. The outlet valve opens during the purging sequence to ensure the purging of the motor enclosure according to EN60079-2/EN50016 .The outlet valve itself can be mounted in any position. The valve closes completely if the purging sequence is finished.
• Test certificate The motor system is provided with a test certificate as shown in the annexure of this documentation.

Structure and Function
In conjunction with an enclosure (motor enclosure, junction box), the EEx-p system F-361.C4 provides a pressurized motor that is in compliance with EN 60079-2 / EN 50016. For this purpose, it has all the facilities and sensors needed to monitor the necessary purging phase and then to monitor and maintain an overpressure within the EEx-p enclosure (motor cabinet).
1 Structure
The controlling system consists mainly of two components which must be installed separately:
• controlling cabinet ST-200C/CM, with built-in piping ,valves, electronic and • the outlet valve VA-100-3H.
The controller F-351 itself monitors and regulates the overpressure in the enclosure, while the digital/proportional valves doses the air quantity needed to achieve the pressurized apparatus.
2 General Functional Description
After a functional test and start-up, the controller F-351 in the control cabinet ST-200C/CM monitors the flowrate of the compressed air or inert gas during the initial purging process, and then monitors and regulates the internal pressure of the EEx-p enclosure with regard to the surrounding atmosphere during normal operation.
Display In three lines of 12 characters each, the digital display shows the enclosure’s internal pressure during normal operation, and the remaining purging time in minutes and seconds during the initial purging process. During normal operation, you can call up further information by pressing the button "OK / Info". Faults which are detected during the self-check are shown here with a number. OK-button The button on the left side (“OK / INFO”) is used in normal operation to call up the stored parameters “Enclosure Pressure”, “Purging Time”, “Function of Relay 3”, “Function of Relay 4”, “Switchpoint of Purge Start”, “Switchpoint of Minimum Pressure”, “Switchpoint of Overpressure” and “Regulation”. During the parametrization, this button is used to select and confirm the various parameters.

Rotary switch The right field (“Menu”) permits access to the Wheel Shuttle® with a tool (e.g. a screwdriver) for parametrizing the controller. With this Wheel Shuttle, you can start the parametrization and set the individual parameter values.
Screw terminal In the lower part of the cover (see page 1), the terminal assignment of the Controller is shown. Terminals 1 to 3 are inputs; they provide electrical power to the Controller. Terminals 4 to 19 are outputs, over which the monitoring unit drives its peripherals, e.g. the digital/proportional controller.
Immediately after the compressed air supply is opened and the main voltage is applied, the internal self-check of the controller begins automatically. Any fault occurring during the self-check sequence is indicated by An explanation of the fault numbers (XX) is given in the manual, section 3.5 “Faults and Troubleshooting”, Table 1: Faults detected during the self-check. If the self-check is carried out successfully, the initial purging of the enclosure commences, ending when at least five times the enclosure volume has been circulated. The purging process is indicated by the message in the display. All the time, the remaining purging time is counted down to 00 min and 00 seconds. After the end of the purging sequence, the Non-Ex units in the enclosure are switched on. The overpressure in the enclosure then constantly monitored for adherence to the setpoint value (factory setting: 2.0 mbar) and also for transgressing of the Min value (factory setting: 0.9 mbar) and exceeding of the Max value (factory setting: 20.0 mbar). Normal operation is indicated by the message in the display.

3 Behaviour of the controller during normal operation In normal operation, the controller F-351 in the control cabinet ST-200C/CM monitors and regulates the internal pressure of the EEx-p enclosure to the setpoint value in relation to the surrounding atmosphere. The limit values set in the factory are: MIN: 0.8 mbar and MAX: 15.0 mbar. At an increased level of internal enclosure pressure (over the limit value for Max) with regard to the surrounding atmosphere, the mechanical valve VA-100-3H opens automatically. This allows the excessive internal pressure to drop. The valve closes again when the internal enclosure pressure has again attained normal values (under the limit value for Max). Function procedure of the EEx p system After connecting the pressure supply and turn on the main switch (Pos.18) the purge valve (Pos.15), the proportional valve (Pos.14) and the outlet valve VA-100-3H are open. Through the adjustment valve (Pos.12) and in addition through the proportional valve and the parallel mounted manual valve (Pos. 9) the pressure air reaches the motor enclosure and flees through the outlet valve VA-100-3H. If the purge flow of the motor enclosure exceeds the adjusted minimum flow value, the purging sequence starts. The remaining purge time is displayed. If the air flow through the motor during the purging sequence drops below the pressetted value for minimum flow, the purging sequence stops. The required purging time depends on the setting of the purge volume (normally 10 times the free volume of the motor cabinet) and the presetted inlet pressure at the pressure regulator (7). After the purging sequence is finished: The power supply of the purge valve (Pos.15) is cut off with the relay K3 in the EEx d box. Thereby the outlet valve VA-100-3H and the purge valve closes. The pressure air now flows only through the manual valve "leakage losses" and the proportional valve in the motor enclosure. The required overpressure in the motor enclosure is now maintained by the proportional valve and the manual valve. Likewise due to compensation of leakage losses. At the terminals –X2 9 and 10 in the EEx d box the signal "ready to start" is given. The overpressure in the motor enclosure is monitored by the pressure switches "Min" and "Max" of the control unit. If the overpressure drops below the presetted value "Min", or exceeds the overpressure value "Max", then K2 and K3 in the EEx d box are switching and a signal is given to cut off the motor power. To prevent a false alarm, as a result of pressure oscillations through the motor housing during the purging sequence, terminals 9 and 10 have a drop-out time delay of approx. 5 sec.

Appendix A Timing diagram purging sequence
T1: Switching on power supply and opening air pressure supply the control unit begins with a self test and the purging sequence of the EEx p motor enclosure starts. With an air flow which is higher than the adjusted value “min air flow” and the air flow is adequate the adjusted purge volume (min. 10-fold inner free motor volume), the motor enclosure is purged.
T2: The purging sequence is finished. The adjusted motor enclosure overpressure is controlled by the leakage compensation (see chapter 5 of main manual). The Non- Ex units can be powered.
T3: Normal operation starts.
Timing diagram operating modus
T1: The purging sequence is finished. The adjusted motor enclosure overpressure is controlled by the leakage compensation (see chapter 5 of main manual). The Non- Ex units can be powered.

Timing diagram errors during purging sequence
T1: Switching on power supply and opening air pressure supply the control unit begins with a self test and the purging
sequence of the EEx p motor enclosure starts. With an air flow which is higher than the adjusted value “min air flow” and the air flow is adequate the adjusted purge volume (min. 10-fold inner free motor volume), the motor enclosure is purged.
T2: During the purging sequence the internal overpressure increases to an excessively high value. The purge operation is aborted.
T3: During the purging sequence the minimum air volume flow falls. The purging sequence is resetted.
Timing diagram errors during the operating modus
T1: The purging sequence is finished. The adjusted motor enclosure overpressure is controlled by the leakage
compensation (see chapter 5 of main manual). The Non- Ex units can be powered.
T2: Normal operation starts. The internal enclosure overpressure is regulated to the setpoint value.
T3: The internal enclosure pressure drops. If the pressure value falls below the switchpoint „Minimum pressure“ in relation to the external pressure, the Non- Ex units are switched off.
T4: Renewed purge.
T5: Normal operation begins.
T6: The internal enclosure pressure rises. The increased internal enclosure pressure cannot controlled down.
T7: If the internal pressure value exceeds the switchpoint „Overpressure“, the Non- Ex units are switched off. The purge valve is powered, so the outlet valve opens. The increased overpresse sinks to operation values.
T8: After the pressure decrease, normal operation begins without purging.

Option: Evaluation of additional signals If wanted, the evaluation of more potential free signals is possible. Therefore the module F-369 will be mounted. This module is directly controlled via EEx i circuits of the control unit F-351.P. Each relay (K2, K3 and K4) is free programmable in his function. The module F-369 itself is mounted in an EE x d enclosure type F-900.031F369. An exchange of the F-900.031F369 against the F-900.001 in already operating systems is only possible, if the control unit is also changed. EEx d control box F-900.031F369 In this EEx d junction box all potential free signals can be picked off. Layout of the cable glands can be different from sketch.
Terminal 1 and 2: Motor stop Terminal 3 and 4: Purging in progress Terminal 5 and 6: Operate F-369 1/2 (K2): free programmable F-369 5/6 (K3): free programmable F-369 9/10 (K4): free programmable
