3 Flame uperviion The flame monitoring device i eparate from the baic unit and connected to the baic unit by a CAN bu. Variou flame enor can be connected to the flame monitoring device. Ionization UV enor Photoreitor (light) 2 contact input Depending on operating mode, two flame enor can alo be combined with one another. All flame monitoring ignal (UV, ionization, light) are evaluated for intenity and can be diplayed on the baic module uing the hand-held programmer. Hand-held programmer The hand-held programmer ha a 4 line LC diplay on which information on the tatu of the burner ytem can be diplayed. Time, date, fault memory, reference value, actual value; operating hour; number of tart-up, frequency, O2 value, automatic burner program election; changing parameter, e.g. preventilation period, ler enable time, potventilation period, tabiliation period, pre-tartup ytem tet. All input and output can be checked for wiring defect uing the key on the hand-held programmer. A paword mut be entered before parameter may be changed. The hand-held programmer i uitable for intallation in the cabinet. Actuator Torque 15 Nm Angular reolution 0.02 Runtime 22.3 to 90 Optical feedback ytem. No ervice life problem in comparion with potentiometer. Protection type IP V upply voltage. No external tranformer required. Digital activation and feedback ignal. Reference point for defining the mechanical zero point of the drive haft. Cable length up to 20 m are poible. Communication option BCS-300 can be connected by mean of different gateway to uperordinate ytem or other external and urveillance ytem. It i connected via the RS 232 interface of the diplay and operating module (AB). Fieldbu ytem - PROFIBUS DP - odbu RTU Remote Data viualiation and torage via internet on the FTP erver. Extended hardware output IO module ytem for activating analog and digital IO component baed on a 2-wire RS 485 bu ytem. 3 8

Ga take-off between the afety valve and the main valve. - Operation with or without valve proving ytem. Four different oil burner ytem program can be elected depending on application. For example with or without pilot valve. Integrated valve proving ytem An integrated valve proving ytem can be implemented with an additional preure witch. Switching time are adaptable to preure, fitting volume and the etting point of the preure witch. Integrated ler For imple application, a ler configurable a a run-on ler or a a tandard ler i integrated. The run-on ler repond to a ignal from 4 to 20 ma. However, it doe not correct diturbance variable. 4 ma correpond to low load and 20 ma correpond to high load. On the tandard ler, the input ignal i alo a 4 to 20 ma ignal. However, the reference value i et uing a PID ler. Diturbance variable are alo corrected. 4 8

5 BCS-Viion - Straightforward graphic window - All key parameter at a glance - Operation by moue and keyboard - Data record can be aved and loaded - Statu diplay - Change of the language of the diplay and operating module Start-up and configuration i alo poible with the PC and the BCS-ViionE oftware. During the etting phae, the burner i topped at variou point in the ramp-up procedure, e.g. pre-purge phae, ignition poition, etc. Setting can now be made. The ramp- up procedure i continued a oon a the etting in each individual phae are completed. All monitoring mechanim are active in etting mode. - Shifting of interpolation point by moue - Saving characteritic curve - Loading characteritic curve All characteritic curve, whether air, frequency inverter, ga or oil, can be repreented graphically. The individual active interpolation point are pecially marked. The intermediate point are repreented a a line. Interpolation point can be hifted imply by dragging the moue. The program compute the intermediate value are automatically. 5 8

6 BCS-E1 for O 2 - O 2 probe i fail-afe and uitable for continuou duty in combination with the BCS Sytem Electrical connection - No reference ga required - Long ervice life of probe (> 2 year) O 2 - probe - The parameter for O 2 optimization are learned automatically with regard to the ytem configuration - O 2 can be witched on and off eparately for each fuel type - Simple regulation at burner tart-up - Continuou digital diplay of O2 meaured value and O 2 optimization tatu - Fuel conumption i reduced ignificantly. - Short repone time of probe -> hort tabilization time of O 2 actual value to the reference value and quick correction of diturbance BCS CAN-BUS - The O 2 level i regulated together with fuel-air ratio. ->Le time i required to complete the tart-up procedure. ~ (AC) 230 V ~ (DC) 24 V Advantage for operation of a ytem with O 2 (optimization) - The O 2 exhaut ga meauring probe i fail-afe and uitable for continuou duty in combination with the BCS Sytem. - The O 2 optimization function adjut the O 2 value pecific to burner capacity, and without a limiting curve, until REFERENCE value O 2 = ACTUAL value O 2. - anipulated variable adjutment i only limited by the range limit of the actuator (air damper or FU) but not by precribed limit band (a with other ytem). - The O 2 exhaut ga meauring probe require no reference ga. The probe i TÜV-approved (by TÜV Süddeutchland = Technical Inpectorate for South Germany) for ue in combination with the BCS Sytem. - Weather-related interference i compenated, thereby achieving an improvement in burner efficiency. - Incomplete combution due to the effect of temperature i impoible. - Fuel conumption i reduced a the burner can be regulated with ignificantly le exce air. 6 8

7 BCS-E1 for peed - Frequency inverter are indirectly activated, irrepective of make, by an analog ignal (4..20 ma) - Eay intallation or retrofitting through BUS technology - The peed uperviion aignment are iued automatically in dependence on load by the BCS Sytem (without flame) - Allowance i made for the frequency inverter, blower motor and Namur ignal read-in in the afety concept of the BCS Sytem (TÜV-approved) - Interactive blower peed adjutment at tart-up - For peed feedback, any proximity witch can be interfaced directly to the module after NAUR Advantage for the operation of a ytem with peed - Reduction of ound emiion (no ound inulation i required in ome cae) - Speed uperviion in every load range - Coniderable aving in electrical energy (up to a factor of 0.5) - The range of the burner i extended by precie adaptation of the combution air to the burner ytem - Soft tarting greatly reduce mechanical tre on the motor and fan impeller - Simplification and improvement of air-ide burner adjutment - Improved adaptability of the burner within it operating area to the exiting ytem contellation Electrical connection FU n / f ~ ~ 3 ~ Namur ignal CAN-BUS Activation FU BCS 7 8
