3 Introduction 3.1 Smoke and heat extraction in the building ”There is no smoke without a fire”. This old proverb can still be applied to our time – and the order of the 2 risk factors ”smoke and fire” is correct too. A number of fires in recent times have demonstrated that, very often, smoke poses a greater threat to people than the fire itself. This shall be in indication of the importance of smoke when discussing the safety of people in the case a building fire has broken out.
3.3 Interplay of ventilation plant and smoke and heat extraction in the event of fire The illustration below shows a possible scenario in the event of fire and the interplay between ventilation plant and smoke and heat extraction. According to the scenario chosen, a fire broke out on the floor in the middle of the building.
3.4 Operation of SED2 in the event of fire The new firmware V1.40 actively supports operation in the event of fire. The focus is clearly on the above mentioned overpressure plants, which can be easily implemented through the use of speed-controlled fans. The change from comfort to fire operation is accomplished by the Essential Service Mode (ESM). For use with the SED2, this function has been completely revised and extended.
Once ESM is activated, “ES“ is displayed on the SED2 BOP (Basic operating Panel). ESM activation can also be assigned to one of the relays of the SED2. Application example of ESM The SED2 firmware offers ESM as a standard feature which can be enabled via a parameter and also appropriately parameterized. We envisage a number of typical applications for the ESM function.
4 Commissioning ESM/Fire Mode with EasyComm software Application Examples The use of EasyComm to commission the functions within ESM will greatly simplify setting certain bits in the ESM control words. 4.1 Application Example 1 4.1.1 Description • In normal operation the SED2 is receiving the setpoint over the analogue input 1, e.g. from a BAC, e.g. DESIGO PX.

4.2 Application Example 2 4.2.1 Description • In normal operation the SED2 is receiving the setpoint over the analogue input 1 e.g. from a BAC e.g. DESIGO PX. • In case of fire the fire control panel signals this to the SED2, it is going in the ESM mode and to a fixed frequency e.g. 40Hz. 4.2.2 Wiring diagram L1 L2 L3 N PE F1 L1 F1 L2 F1 L3 1 DC 10V 2 DC 0V Setpoint 0...

5 Commissioning Wizard for Essential Service Mode 5.1 Introduction Up to now the SED2 drives have been commissioned over the BOP/AOP respectively over EasyComm which is a parameterisation and monitoring tool for the SED2 family. This may be inefficient particularly with more complex applications such as ESM and bigger projects. We have recognized that we can simplify significantly this commissioning process by using the so-called SED2 Commissioning Wizard.
5.2 Parameterisation of ESM function This example shown is equivalent to example 2 in Chapter 4.2 – Application Example 2. Following windows will show up, to make life as easy as possible: 1 2 Note If the user clicks «No» it will take him back to the start. 3 4 27 / 44 Siemens Building Technologies Application Guide «Fire Mode» Commissioning Wizard for Essential Service Mode CM1A5192en_01 23.10.

An automatic installer makes the installation of the Commissioning Wizard easy. 29 / 44 Siemens Building Technologies Application Guide «Fire Mode» Commissioning Wizard for Essential Service Mode CM1A5192en_01 23.10.
6 Essential Service Mode (in-depth information) • With V1.40 and higher, all SED2 errors and warnings will be ignored, the exception being hard errors, such as F0001, F0002, F0003, F0022 and F0023. These hard errors can not be ignored since they could lead to the destruction of the VSD.
6.1 Assigning the ESM function to a DIN (Digital Input) In accordance with the standards, all functions required of ESM can be assigned to the same DIN and therefore eliminate the need for any additional inputs. Our recommendation is to use DIN2 for ESM.
6.3 Defining the main Speed (Frequency) Setpoint for ESM The speed/frequency setpoint will generally be defined during Quick Commissioning and relates to P1000 in000 only. PID control is not activated. 6.3.1 ESM and standard setpoint are the same If the ESM setpoint is going to use the same source of setpoint as is used in standard mode, then there is no need to change P1000 in000 from what is set during Quick Commissioning.
P1000 in000= ESM set-point setting 'Standard' set-point MOP Up/Down Keys Analogue input 1 Fixed Frequencies AOP/EasyComm via RS232 P1/N2/USS via RS485 Comms Module LON Analogue input 2 Example 1 1 2 3 4 5 6 7 MOP Analogue Fixed Up/Down input 1 Frequencies Keys 1 2 3 11 21 31 41 51 61 71 12 22 32 42 52 62 72 13 23 33 43 53 63 73 AOP or EasyComm via RS232 port 4 P1/N2/USS via RS485 terminals 5 14 24 34 44 54 64 74 15 25 35 45 55 65 75 Comms Analogue Module LON input 2 6 7 16 26 36 46 56 66 76 1
Parameter Index P0003 - 1 P1000 in000 2 P1271 in001 P1001 - Required: P1000 in000= x3 Default Set to Function and description 0.00 3 Access Level Set access level to Expert x3 Frequency setpoint Ensure FF(3) is the main setpoint and x=additional setpoint ESM Control word 2 Change bit0 to active. Enables FF1 ? 0~50Hz Fixed Frequency 1 Input desired frequency (x =standard setpoint) Display of P1271 in001 (ESM Control word 2) on the BOP Alternatively, use EasyComm to set the correct bit.
6.4 Reverse Direction in ESM/Fire Mode If no changes are made, the direction of rotation in ESM will be the same as it is in normal operation mode. Parameter Index P0003 - P1271 in000 P1110 in000 Default Set to Function and description 1 3 1.0 0.
Example 2 If you use DIN1 as ON/OFF1 (setting 1 = default) and DIN2 as ON reverse/OFF1 (setting 2) and in addition the ESM is set to reverse the behaviour of the SED2 is as follows: DIN1 (ON/OFF1) 0 0 0 0 1 1 1 1 DIN4 (ON reverse/OFF1 0 0 1 1 0 0 1 1 DIN2 (ESM) 0 1 0 1 0 1 0 1 Motor Direction Normal (Off) Reverse Reverse Normal Normal Reverse Normal or Reverse* Normal or Reverse* * Depending on which command is given first (DIN1 or DIN4).
6.5 PID Control in ESM/Fire Mode It is possible to configure PID Control as follows: Standard Mode Yes Yes No No 6.5.1 ESM/Fire Mode Yes No Yes No Chapter 6.5.1 6.5.2 6.5.3 6.5.4 PID Control in both ESM and Standard Mode Normal operation mode PID control should be configured as described in the Commissioning Guide. P2200 in000/in001= 1.0 or whatever the source is.
6.5.2 PID Control in Standard mode but disabled in ESM/Fire Mode Normal operation mode PID control should be configured as described in the Commissioning Guide. P2200 in000/in001= 1.0 or whatever the source is.
6.5.3 PID Control in ESM/Fire Mode but disabled in standard Mode PID control in normal operation mode is switched off. P2200in000=0.0 All other PID parameters are set to suit application ESM/Fire Mode: Parameter Index P0003 - P1271 in001 P2200 in000 Default Set to Function and description 1 3 0.0 0.0 P2xxx Access Level Set access level to Expert Activate bit 08 and de-activate bit12 to enable PID in ESM PID Controller leave setting at 0.
6.6 Indication of ESM/Fire Mode 6.6.1 BOP indication of ESM/Fire Mode Once ESM has been activated by closing the DIN, the display on the BOP will flash every 6 seconds ES and alternate with the value set in P0005. This will not appear on the AOP. 6.6.2 Relay output indication of ESM/Fire Mode If a relay is required to change state once ESM is activated, the same value that is used to activate P1270 can be used for the relay.
The following parameters will need to be considered for ESM even if P1210 is different to setting 6 in normal operation mode: P1212 (time to first restart) = 30 seconds default P1213 (restart time increment) = 30 seconds default Note If P1210 = any setting other than 6 when ESM is not activated (normal operation mode), when ESM is active the setting of 6 will not be visible as this will occur internally. 6.6.
6.7.2 Starting the SED2 in ESM/Fire Mode Enabling ESM will ALWAYS RUN the SED2, even if there is no RUN command activated in the standard1a settings. Once ESM/Fire Mode has been enabled, the display on the BOP will flash ES Example: within a building the Air Handling Units may be stopped at night-time or weekend. If a fire is detected, the standard control from the Building Management System is overridden by the Fire Control Panel (FCP) if required.
