Install the battery if necessary.- Charge battery of the BT 200 via char-ging shell (approx. 4 hours).U Attention!The battery is always delivered uncharged.The charging shell is not included and must be ordered separately.- Remove the BT 200 from the chargingshell. The device is ready for operation.English 03/99 BT 200 (S)J31069-D0075-U001-A1-7618Page 43 Normal ModeThe BT 200 is turned on with the ON/OFFbutton.Keep the ON/OFF button pressed until you see a reaction on the display.Standby displayThe following display appears for approx. 3seconds after the device is turned on.Battery displayThe battery capacity display is then shown forapprox. 3 seconds.Operational displayAfter the battery display disappears, the BT 200 assumes normal mode and displays thestart screen for the wiring test.Only the wiring test can be performed in nor-mal mode.Energy saver modeIf no keys are pressed for approx. 3 minutes and no measurements are being performed,the BT 200 goes off automatically.BT 200 03/99 English 3.1 Wiring TestPrinciple of measuringThe wiring test for a bus segment is per-formed between the BT 200 and the test plugconnector. During the initialization phase, atest can be performed from connector to con-nector. See figure 2. The test connector isalways installed on the one end of the bussegment.Short circuits can also be determined outsidethe test path. The bus segment may only beequipped with a terminating resistor at thebeginning and at the end.Fig. 2 Step-by-step measuring principlePerforming the testNo stations may be connected to the bus line.The test is started by pressing the TEST key.One of the following two messages is dis-played if the test was concluded successfully.For one terminating resistor (as long as in-stallation has not been completed, only oneterminal resistor is present)After installation has been concluded, two re-sistors must be inserted.The test is concluded by pressing the OK key,and a new wiring test can be started.The wiring test can also be concluded or ter-minated at any time by pressing the ESC key.

Otherwise an even numberof wire mix-ups will not be recognized.Short circuitLocate and correct the short circuit.A frequent cause (e.g., of shield short circuits)is the incorrect application of shield braiding in the plug connectors.BT 200 03/99 English Line or shield breakIf several cores or at least one core and theshield are broken or not connected, the BT200 cannot identify the interruption unambi-guously.To obtain a correct measuring result for shieldbreak, the shield may not be connected withground.With all four messages, first check the plugconnectors in question. If these are okay, re-place the cable.None or more than two terminating resistors Page with the "→""←" keys.Place a terminating resistor at the beginningand end of the bus segment.Page with the "→""←" keys.Remove or deactivate all terminating resistorsexcept the two at the beginning and end ofthe bus segment.(S)J31069-D0075-U001-A1-7618 Page 7English 03/99 BT 200 (S)J31069-D0075-U001-A1-7618Page 84 Specialist ModeYou can switch from normal mode to special-ist mode by pressing ESC and OK at thesame time.The following functions are available in spe-cialist mode.- Wiring test.

See figure 4.U Only the included test cable may be used for this connection.Fig. 4 Point-to-point connectionTurn on the slave since the test must be per-formed with an active slave.Start station test.Set address of the slave to be tested asshown below."←" "→" Change cursor position."↑" "↓" Increment/decrement number.Accept the set three-position number with OK,and start test.Test resultsPossible test results are listed below.- RS 485 okay (slave okay)- RS 485 defective. (No continuous signal receipt; repeat test.)- No response. (Nothing received; wrong slave address may have been set.)- 5V : (corresponding measured value)- RTS signal (YES or NO)4.3 Branch TestThis can be used to check the availability ofall slaves on PROFIBUS or to address an in-dividual slave.The branch test can also be performed be-yond repeaters/LWL.Performing the testDisconnect all masters from the bus (e.g., PG,OP and CP). See figure 5.Connect BT 200 to the bus.Set the baud rate configured on the bus onthe BT 200.Set the desired address for individual slavetest.Set address to "000" for the total test.Start test.Fig. 5 Measuring principle of the branch testTest resultsDuring the total branch test, each availableslave is indicated in a list of available stations(i.e., LIFE LIST).- LIFE LISTFor an individual test- No response. (e.g., No station with thisbus address on the bus.)- Faulty station. (e.g., a slave number has been assigned twice.)4.4 DistanceThe distance can be measured to determinethe length of the PROFIBUS cable.Performing the testDisconnect all bus stations from the bus.Connect test plug connector to one end of theline and the BT 200 to the other end. (Re-move termination for BT 200.)Start distance measurement.After the start, the BT 200 requests three val-ues which must be entered on the keyboard.- Loop resistance (default = 110 Ω/km)The default value can be changed viamenu item Service.- Number of plug connectors with longitu-dinal inductivity (12 Mbaud connector) - Resistance value per connector(default = 0.32 Ω)After entry of the last value and confirmationwith OK, measurement is performed. Measurement resultsThe following appears on the display.The following error messages can occur dur-ing measurement.- No resistor inserted.- Display "0 m" (no plausible length deter-mined)- More than 1 resistor inserted.Possible causes of errors:-Distance < 15 m-Stub lines, located on the measuring pathCorrect the error, and repeat the measure-ment.4.5 Reflection TestThe reflection test can be used to determinefaults (e.g., short circuits and interruptions) orto confirm the distance measurement.Reflexions can occur in the following situa-tions:-Stub lines exist.-Too many terminating resistors havebeen inserted, or none have been in-serted.-Change to a wrong type of cable occurs within the measuring path.-Cable installation is not correct (e.g.,luster terminal connection and so on).Performing the testDisconnect master from the bus, and makesure that no bus communication occurs.Connect BT 200 to one end of the line.Start reflection measurement.Test resultsIf no reflection (i.e., fault) is detected, the fol-lowing message appears.If a reflection is detected, the following mes-sage appears.The number in the display specifies the dis-tance in meters from the measuring point tothe faulty point.If the distance of the reflection measurementcorresponds to a previous distance meas-urement, this distance measurement is con-firmed. The wiring of the bus segment whichwas measured is correct.4.6 ServiceSettingsThe following settings can be changed in theService menu.-Language (German/English)-Loop resistance (50 to 200 Ω/km)-Baud rate (9600 baud to 12 Mbaud)-Contrast (↑↓)Default valuesIf you want to reset all values to their statuson delivery, keep both cursor keys pressedfor approx. three seconds after turning on thedevice.DisplaysThe Service menu gives you the following in-formation.-Firmware version-Battery capacityHardware testThis tests the internal hardware.CalibrationCalibration is not necessary when the stan-dard type-A PROFIBUS cable is used.The accuracy of distance and reflectionmeasurement is achieved by calibration with 2test cables of different known lengths.Fig. 6 Principle of calibration5 Maintenance and Trouble-Shooting5.1 Charging Status of the BatteryThe charging status of the battery is indicatedfor approximately 3 seconds during startup.This display then disappears.The charging status can also be indicated viathe service menu during operation.I f the battery goes dead during operation, thecharging status begins to flash.5.2 Changing the BatteryU Attention!

打开电池端盖，检查电池是否已经装好，如果需要的话安装好电池。
在更换电池期间，不能进行测试。
3 常规模式BT200由开关键打开。
保持其按下直到在屏幕上出现反应为止。
标准显示在开机后将显示下面图画然后显示电池情况电池状况显示过后，BT200默认进入常规模式并显示用于写测试的开机屏幕在常规模式下只能进行写测试。
当在登录模式下（指针看起来是不一样的），在每次测试之后会再出现如下画面电能节省模式如果3分钟内没有进行任何操作，那么BT200将会自动关闭3.1 写测试测量原则总线段的写测试在BT200与测试连接器之间进行。
在安装阶段，可以在连接器之间进行一个测试，如下图所示，测试连接器通常安装在总线段的另一端。
在测试路径之外也会造成短路。
总线段必须要在两端设置终端电阻。
进行测试可以在连接站点或断开的情况下进行测试。
在按下测试键之后，测试就开始了。
如果测试成功的话，将会显示下述两幅画面之一。
只有一个终端电阻（只要安装没有完成，只会显示一个终端电阻）当安装完成之后，会出现两个终端电阻。
按下OK键，测试即结束。
接下来也可以进行新的测试。
测试也可以在按下ESC键之后被终止。
3.2 写测试的错误信息站测试检测是否将所有站点以及电能部件的能量已经断掉。
线混合在相应的连接插头之间交换电缆线芯短路定位并纠正短路故障。
