3 Page PolyGard Gas Controller System DGC-0 Preliminary Remark These instructions explain the basics of dimensioning, laying and termination of the cables as well as the procedures of commissioning of the Gas Controller system DGC- 0. These data were compiled by us with great care, but deviations can t be excluded. Therefore we shall not be liable for possible mistakes in this description. At commissioning, the technical requirements and regulations concerning wiring, electrical security, environmental conditions, fire protection etc. must be considered on site. Introduction For simple and fast installation of the field bus cable, the DGC-0 system is solely geared to the Twisted Pair Cable JY(St)Y xx0,8lg concerning communication, operating voltage supply, terminal connection etc. For this cable you have to consider the following factors when dimensioning and installing: Bus installation Physical load capacity. Installation of Field Bus Cable The installation of the field bus cable to the bus transmitters ADT-X and/or MD- has to be executed only in line topology. Branch lines are not allowed. For reliable communication the cable length shall not exceed 900 m per network segment. The cable length is also limited essentially by the physical load capacity. Section. gives examples for the cable lengths in dependence of the connected field devices; they must be adhered to in any case.

4 Page. Termination Each segment needs an ohmic terminating resistor of 0 Ohm at each of the both cable ends. These terminating resistors are already integrated in the DGC-0 system. A resistance of 0 Ohm has to be connected at the bus end between the bus lines BUS_A and BUS_B. 0 R BUS_B BUS_A 0 V + V ADT-X BUS_B BUS_A 0 V + V 0 R DGC-0 Fig. Termination of field bus end at the ADT-X Internal termination DGC-0. Physical Load Capacity of the Bus Cable The field bus transmitters work with a nominal operating voltage of VDC. This tension is impressed via the shared -wire Twisted Pair Cable (JY(St)Y xx0.8lg) with a cross-section of 0. mm. Therefore you have to calculate which cable length is allowed in dependence of the total power of the connected field bus transmitters and EP-0 modules, in order to obtain the required minimum terminal voltage of VDC at the field bus transmitters and 8 VDC at the EP-0 modules.. Calculation of the Cable Length As described above, the field bus cable is only laid in line topology without return line. An Excel program is available for the exact calculation of the admissible cable length. You can read the estimated cable length for the maximum configuration from the following table.

6 Page Commissioning For fast and comfortable commissioning we recommend proceeding as follows. Especially the given specifications of the field bus cable have to be checked carefully, because it is here where most of the causes for problems of the field bus communication appear.. Optical Check Right cable type used. Cable topology and cable length. Correct connection at each bus transmitter according to the following figure. Termination at the end of each segment. Pay special attention to the fact that the polarity of BUS_A and BUS_B is not reversed!

7 Page. Check Short-circuit/ Interruption/ Cable Length of the Bus Leads Disconnect the bus leads from pin and pin of the DGC-0 central control. Connect ohmmeter to the loose leads and measure the total loop resistance. See fig. Loop resistance. The total loop resistance is calculated as follows: R (total) = R (cable) + 0 Ohm (terminating resistance) R (cable) = Ohm / km (loop resistance) (JY(St)Y xx0,8lg) R (total) = < 0 Ohm Short-circuit Look for short-circuit in the field R (total) = infinite Cable interruption Look for cable interruption in the field R (total) = > 0 Ohm < 0 Ohm Cable is OK The cable length can be calculated in a sufficiently exact way according to the following formula. Total cable length (km) = (R (total) 0 Ohm) / Ohm If the field bus cable is OK, reconnect it to the central control. R =, Ohm/00m + 0 Ohm DGC-0 Central control Ohm ADT-0 (Terminating resistor) 0 R ADT-0 ADT-0 ADT-0 ADT-0 Fig. Loop resistance GAINBDGC0_E_0 Phone.: 009(0)8/900-0 Fax: 009(0)8/900- Specification subject to change without notice.

9 Page 9. Addressing of the Field Bus Transmitters After having checked the field bus successfully, you have to assign a measuring point (MP) address to each field bus transmitter. The addressing is done with the service tool DGC-0-STL in the menu Addressing directly at transmitter. The service tool always communicates via the GC-0 with the transmitter, not directly with the transmitter. Therefore addressing is only possible when the GC-0 is ready for use and the field bus is functioning. The status LED of the bus transmitter is weakly illuminated when the operating voltage is active (voltage indicator) An automatic link connection STL <> GC-0 <> transmitter is established when connecting the DCG-0- STL to the service tool jack of the transmitter. If this connection is OK, you can read the actual transmitter address in the menu Address. 0 = Address of new transmitter XX = Actual transmitter address = Communication error! See. Addressing according to the following description: MSR Electronic Credits: 00 Starting menu Addressing Address transmitter Address 0 Address 0 Address 0 = The transmitter has no address yet (delivery status), communication to the GC- 0 is OK, addressing possible. XX = The transmitter has already an address. Address can be changed. = The transmitter has no communication to the GC- 0 Controller (central control) Addressing not possible, eliminate communication error. Cursor is activated, by using Takes over entered address in the service tool. enter desired address. The previous address is displayed again for one measuring cycle, afterwards the assigned address is taken over by the transmitter. Addressing DT- 0 finished. Unplug service tool. The measuring point (MP) is activated automatically at the GC-0 by addressing the transmitter. After successful addressing and registration the GC-0 queries periodically the measuring point of the transmitter. The transmitter responds to every query of the GC-0. This reply message is indicated by a blinking pulse of the status LED at the transmitter. The cycle time is about to sec. depending on the number of the connected bus subscribers. Note: Due to the great flexibility of the DGC-0 system concerning addressing and configuration there is also the possibility to assign a transmitter address several times. The DGC-0 system, however, is not able to define the repeatedly assigned addresses clearly. Therefore it is necessary after commissioning to check in the menu Measuring points of the GC-0, if all assigned addresses are activated.

10 Page 0. Communication Error Communication errors at commissioning are nearly always due to mistakes in laying the cables, in connecting to the terminals and in terminating. Therefore the following checks have to be performed: Bus line reconnected after measurement of the loop resistance? GC-0 controller in operating mode. Check the operating voltage at the transmitter (, Pin + and Pin -; U min = VDC) Check communication at another transmitter. If communication OK here, exchange previous transmitter. Check bus leads for short-circuit or interruption. See. Check polarity of the system bus (BUS_A BUS_B). See. Check termination. Terminating resistance of 0 Ohm at the beginning and at the end of the segment. Check cable topology and cable length. Only line topology <> No branch lines!! Cable length depending on the load. See.. Commissioning of Expansion Modules EP- 0 Up to two expansion modules (EP- 0) with five alarm relays each can be connected to the DGC-0 system via the RS- 8 bus. Each connected EP- 0 expansion module is registered in the menu System parameters. In order to recognize the position of the EP- 0 modules, a module address is assigned to each module via the address switch. The table shows the assignment of the relay and analog outputs to the module addresses. Module- Addr. No. Analog Outout No. 0 to 0 0 to 0 to 0 to 0 The address switch is located behind the connecting plug X. Unplug X for addressing.. Adaptation of System Parameters At commissioning the alarm relays must be assigned to the alarms (thresholds) for each measuring point. For all other parameters, the values are deposited as defaults, which can be changed at any time if necessary. See also Description of PolyGard Gas Controller DGC-0.

11 Page Calibration New transmitters are always delivered factory-calibrated by MSR-E. This is documented by the calibration label indicating date and calibration gas. In this case calibration is not necessary during commissioning. For the calibration of the bus transmitter (MP X.) an automatic routine is deposited in the menu Calibration of the service tool DGC-0-STL. The measured value of the analog transmitter (MP X.) is displayed in the same menu for the calibration with the zero - gain potentiometer. While the calibration menu is open, the MP doesn t transmit any measured values to the GC-0 controller. Therefore applying the calibration gas to the sensor, bus or analog transmitter, doesn t release an alarm. As facilities you only need the zero gas and the calibration gas, the calibration adapter and an extraction set. Prior to calibration the sensor must be connected continuously to the power supply for a running-in period. The running-in period of the different sensors can be taken from the following table: Sensor/Gas type t in 0 CO h 0 Ex h 0 NO h 0 NO h Project protection To avoid unwanted access to the sensitive calibration data by a third party, every customer gets a project key. All projects of the customer are delivered with this key. This key is also deposited in each STL bought by that customer. After opening the menu Calibration, the STL asks first of all for the project key of the central control. Only if the key is approved in the STL, calibration will be possible. If the keys do not correspond to each other, the following message will appear: NO ACCESS AUTHORISATION Prior to calibration please read also the section Credit system. The calibration procedure is described on the next page. GAINBDGC0_E_0 Phone.: 009(0)8/900-0 Fax: 009(0)8/900- Specification subject to change without notice.

13 Page. Credit System A credit system for the calibration of the transmitter, MPX., is integrated in the STL. For each successful calibration of a transmitter the credit account is reduced by one credit point. No credits are necessary for calibration of the analog transmitters. In the starting menu of the STL the number of the actual credit points is displayed. Due to this information it is possible to load new credits in time. In delivery status 00 credit points are already activated in the STL. Reloading credit points New credit points can be loaded by entering a -digit code without laborious returning of the STL device to MSR- E. This code can be asked from MSR- E by phone by indicating the -digit STL serial number. A block of 00 new credit points is released with each code number. Due to the telephone transit of the code, reloading new credits even can be done directly by the service technician during maintenance. The STL serial number can be read from the type label and is deposited in the menu Credit Menu Credit Addressing Address menu Credit menu Credit menu Number of credits Q Number of credits Serial number XXXXXX Serial number of the STL Load credits Loading credits Enter credit code X XX XXXX XX = Block No. of the next 00 credits XXXX = Enter the -digit code GAINBDGC0_E_0 Phone.: 009(0)8/900-0 Fax: 009(0)8/900- Specification subject to change without notice.
