Page 3: General Information
There is a special built-in trimming resistor in the sensor’s connector that defines the sensory properties which are necessary for the sensor’s function. Only in combination with the specially de- veloped Scan Tronic cable can the wide band sensor function. This cable controls the power supply to the probe’s heating element. In this way the sensor has optimal operating condi- tions. -

Thread........M18x1,5 Calibration interval 6 month 1.3.2. Scan Tronic LSU- cable A control cable specifically developed to connect the probe with the signal repeater. One end of the cable has a 4-pin multiplug that connects to the signal repeater, while the other end of the cable has a 6-pin multiplug that connects to the probe. -

2.0. Installation 2.1. Control at delivery After unpacking, please confirm that the delivered items are in accordance with the packing list. Possible inconsistencies should be reported to the supplier immediately. If some parts are dam- aged please contact the shipping company. 2.2. Instrument identification The oxygen control system OC 2010-LSU, as standard, consists of a measuring probe OS 2014, and signal amplifier OC 2010-LSU, a guide tube including a gasket and 4 mounting screws are optional. -

2.4. Installation of the oxygen probe The drawing shows the fitting of the probe in the flue wall. In minor flues, the probe is mounted in a M 18 x 1,5 mm thread hole. In larger flues the guide-tube is used. The flange of this guide tube is mounted onto the wall of the flue. If possible the probe must be mounted on the topside of the flue, assuring that any possible dust and oil carbon are not deposited... -

4.0. Adjustments and settings 4.1. Routine calibration The following paragraph describes routine calibration of the OS/OC 2010-LSU system. The units are calibrated prior to shipment and need no supplementary calibration before the first rutine calibration. Calibration is generally done every 6 months. Introduction Needed tools: 1. Cross-headed screw driver PZD no. 2 On calibration the measuring cell OS 20140 is 2. Screw driver for adjusting (3 mm flat). -

Page 13: Selecting 0 - 20 Or 4 - 20 Ma Output
4.3. Selecting 0 - 20 or 4 - 20 mA output. The current loop output signal from OC 2010 can - by sliding the „FUNC.“ switch - be selected either as 0 - 20 mA or as 4 - 20 mA. The „FUNC.“ switch can be accessed by removing the top cover of the Signal Amplifier. -
Page 14: Passive Loop
4.4.2. Passive loop In example 2 the receiver is supplying loop power (passive loop). If in doubt whether to use an active or pas- sive loop connection it is recommended to use an active loop (see previous page) as the first alternative. Passive loop is normally only used on installa- tions where a larger number of loop powered 4 - 20 mA transmitters are used (i.e. -
Page 15: Scalation
6.0. Scalation The current loop output of OC 2010-LSU is either 4 - 20 mA or 0 - 20 mA selected according to chapter 4.3. Selecting the 0 - 20 mA output one % of oxygen equals one mA (1 : 1). Selecting 4 - 20 mA one % of oxygen equals 0.81 mA (n x 0.81) + 4 . Actual measuring range is limited to 0.5 % through 20.9 % using the underrange below 0.5 % as error indication "LLL" and overrange above 20.9 % "HHH" for ambient air calibration. Signal conversion of the logaritmic signal from the sensor to a linear output signal is done digitally and the output comes from an 8 bit D/A converter. This gives a finite resolution of 81.6 µA per step of the output signal and forms a staircase step increasing output. -
