The analog load cell signal (weight) is converted into a serial data telegram. The transmitter conforms to class OIML III/EN45501 ( 3000 d). Protection mode: field housing, IP65 Calibration with or without weights (mV/V method). Calibration/configuration is via software/menu-guided. Other possibilities: - Correction of characteristic dependent of zero correction/hysteresis after removal of calibration weights - mV/V calibration with increased accuracy (error < 0.1 %) by entry of certified load cell data whereby the local gravity conditions are taken into account. - As calculations are automatic, there is no need for extra calculations An analog test permits checking of the analog/digital converter. Built-in display for gross or net weight (configurable). The weight unit and the decimal point (if required) must be marked by adhesive label. The auxiliary display is not suitable for weights and measures applications, it shows '- - -' dashes in W&M mode. With configuration for net weight, '-----' dashes are displayed in the untared condition. PTB certificate of conformity: refers to module PR 1710/6x (built-in) with a hint on the installation in transmitter PR 1711/6.. The PTB certificate of conformity corresponds to class [EEx ib] IIB+C according to EN 50 014 - 1977/EN 50 020 - 1977 (European standards PTB + CENELEC) for the load cell circuits (load cell supply, input signals). However, PR 1711/6. must be mounted outside the explosion-hazarded area, because the remaining circuitry (supply voltage, interfaces) are not suitable for installation in the explosion-hazarded area. The intrinsically safe circuits (load cell supply, input signals) are galvanically isolated from the remaining circuitry and are not connected to the common 0V reference potential. Option/ projects Sartorius Instruments with modified opto-coupler outputs (3.4) can be installed in zone 2 of the explosion-hazarded area, provided that they are ordered additionally with a certificate for zone 2 concerning 9405 000 10601. For projects, PR 1711 with 24 V supply is available, see "Additional Information" 9499 059 39541. 5 Description PR 1711 Operating Manual 1.1 Interfaces Each unit is delivered with 2 serial interfaces: the service interface is located on the front panel and an interface module for the communication interface is fitted additionally. 1.1.1 Service interface A service interface (operator terminal interface) for: - configuration - calibration - weight display - weight status display - limit and digital input and output status display - entry of control functions - entry of limit values, fixed tare value, fixed value for the analog output - digital output setting via PLC markers - remote display Terminal connection is via the built-in RS232 interface (no additional module required). 1.1.2 Communication interface A supervisory system interface (communication) for transmission of: - weights - scale parameters - weight status - control functions - entry: limit values, fixed tare, fixed values for the analog output - direct digital output setting - digital input and output reading - as a remote indicator or as a printer interface (freely configurable send string). Output: weight. Caution: The interface module must be specified by the type no. when ordering the PR 1711/.. ! Type PR 1711 /61 PR 1711 /62 PR 1711 /64 equipped interface module current loop PR 1601 RS232C PR 1602 RS422/485 PR 1604 see chapter 3.6.2 3.6.1 3.6.3 3 protocols are available for the supervisory system interface: EW protocol. This protocol is suitable for master - slave operation (without master controls n – PR 1711/.. units) DUST protocol '3964R', standard protocol and protocol with S5 header J-BUS/MOD-BUS protocol Remote data transmission with an external modem is possible. Unless a supervisory system is used, one or several remote indicators (PR 1627/.. PR 1628/..) or a printer (freely configurable send string) can be connected via this interface. Output: weight. 6 Sartorius PR 1711 Operating Manual Description 1.1.3 Analog output The analog output can be defined for: - gross or net weight - fixed value (via communication or service interface) In case of error, the analog output goes to a fail-safe condition (e.g. load cell/ADC error or exceeded measuring range). 1.1.4 Digital interfaces 3 optocoupler inputs (passive) for : - zero setting - tare/untare, read/set fixed tare - G/N weight selection - enabling of data transfer to the printer - set/delete SPM flag The supervisory system can read the status of these inputs. 3 relay outputs for the control signals: - weight status - limits - direct control via the supervisory system - SPM marker 1.2 Limits 3 independent limit monitoring functions are available. Adjustment is via configuration, however, alteration via communication is also possible. The limit values can also be displayed and modified via remote indicator PR 1628/xx (see relevant documentation). 1.3 Control signals Set zero, tare, untare, analog test, weight display mode selection, printer start. 1.4 Remote display For remote display connection, the 'communication' or 'service' interfaces (9 pol connector) are available. The remote display (PR 1627/ PR 1628) also permits operation of the indicator. The service interface allowed the connection of one remote display PR 1627 or PR 1628/00 or PR 1628/24 (RS232 mode) Max. 8 PR 1711 units can be connected to one or n - remote displays (communication interface - BUS system), see operating manual 9499 050 27518, PR 1628/.. Rel. 2.33 chapter 8 TOKEN PASSING Sartorius 7 Safety Hints PR 1711 Operating Manual 2 SAFETY HINTS 2.1 Initial inspection Check the contents of the consignment for completeness and note whether any damage has occurred during transport. If the content is incomplete or damaged, a claim must be filed with the carrier immediately, and the Sartorius sales or service organization must be informed to permit repair or replacement of the unit. 2.2 Versions with intrinsically safe load cell interface This unit was built and tested in accordance with standards EN 50014 and EN 50020. It is an accompanying apparatus acc. to EN 50020 with the explosion protection ‘Intrinsic safety’ II(2)G [EEx ib] IIB/C. For installation, the specifications in the EC type examination certificate and the standards for installation of electrical apparatus in explosion-hazarded areas (e.g. VDE 0165) must be followed. The potential equalization line can be connected to 'terminal for potential compensation'= (recommendation). Protection class I of IEC 1010 corresponding to the safety regulations for measuring and control instrumentation is applicable. The protective earth must be connected to terminal PE of the supply voltage connection block. Before commissioning, acceptance of the installation by an expert is required. The unit has left the factory in safe condition. To maintain this condition and to ensure safe operation, the user must follow the instructions and warnings given in this documentation. 2.3 Mounting position The unit can be mounted in any position. PG cable glands should not point upwards (water ingress). Heat influences, e.g. direct sun radiation, must be avoided. The environmental conditions specified in the technical data must be observed. 2.4 Before commissioning Visual inspection! Before commissioning, after storage and transport, the instrument must be inspected visually to preclude mechanical damage. 8 Sartorius PR 1711 Operating Manual Safety Hints 2.5 Opening the instrument When removing covers or parts by means of tools, live parts or terminals may be exposed. Capacitors in the unit may still be charged also after disconnecting the unit from all voltage sources. CAUTION DANGER TO LIFE ! 2.6 Supply voltages The unit can be used for the following supply voltages: 115 V/ 230 V AC (selectable internally) Ensure that the selected operating voltage corresponds to the rated supply voltage at the place of installation. When connecting the mains voltage cable (including protective earth) or other supply leads, the instructions given in this operating manual must be followed. As the unit has no main switch, it is ready for operation after connecting the supply voltage. Therefore, an on/off switch for interrupting the two supply voltage phases must be used. 2.7 Repair and maintenance Repairs for PR 1711/ 6.. Repairs are subject to checking and can be carried out only at the Sartorius Hamburg GmbH factory in Hamburg. Maintenance work may be carried out only by trained personnel. The relevant precautions must be taken. Make sure that the construction of the instrument is not altered to the detriment of safety. In particular, leakage paths, air gaps and insulation layers must not be reduced. Fuse: only the mains fuse on the motherboard may be replaced (see chapter 3.2). Note that only fuses of the specified type and current rating in accordance with IEC 127 may be used for replacement. Using repaired fuses and short-circuiting of the fuse holder are not permitted. Fuses may be replaced only by a qualified person aware of the implied hazards. WARNING ! Before replacing a fuse or selecting the supply voltage, the instrument must be disconnected from all voltage sources. Sartorius 9 Safety Hints PR 1711 Operating Manual For special attention during soldering (soldering is only permissible for supply voltage changing): Switch off the supply voltage, use only a low-voltage soldering iron which is galvanically isolated from the mains. Suitable soldering irons should have temperature control and various soldering tips, e.g. Weller Magnastat WTCP or WECP, and Ersa TC 70/24 V. With too hot soldering iron, the printed circuit tracks may be released from the printed circuit board, whereby the printed circuit boards are destroyed. 2.7.1 For special attention The manufacturer cannot be held responsible for personnel injury and damage caused by an instrument repaired incorrectly by user or installer. 2.7.2 Failure and excessive stress If the instrument is suspected of being unsafe, take it out of operation and protect it against accidental operation. This is the case when the unit - is physically damaged, - does not function any more or - is stressed beyond the tolerable limits during storage, operation or transport. 2.8 Disposal Electronics scrap is special waste. Please follow the instructions of your local disposal company. 10 Sartorius PR 1711 Operating Manual Installation 3 INSTALLATION 3.1 Mounting The transmitter is installed in a field housing (IP65).

This applies also to the limit values, fixed analog output value, current zero setting and tare values. Data back-up in the EAROM is partly automatic (set zero, tare), partly on command (configuration, calibration, limits, fixed analog output values, fixed tare). 4.1.1 Write protection The calibration data are write-protected via a switch. Additional data saving in a back-up file is possible. Advantage: when replacing the PR 1711/.., re-calibration/ configuration is not necessary. No built-in battery is provided. A mains failure is registered in a PLC address. 4.1.2 Calibration data 1. After power-on the calibration data are loaded from the EAROM into the RAM. 2. With the function [Calibration]-[New]-[Reset all to default]-[Yes] all default calibration data are loaded from the PROM into the RAM. 3. During the calibration the calibration data in the RAM are modified. 4. The function [Exit calibration]-[Save] stores the modified calibration data in the RAM into the EAROM. Sartorius 23 Calibration and Configuration PR 1711 Operating Manual 4.1.3 Configuration data 5. If the EAROM is erased, the default data are loaded from the PROM into the RAM. 6.

The configuration settings are independent of switch CAL, i.e. access to the configuration settings is always possible (except with protection via the access code). 4.2.1 Limit, fixed tare, fixed analog output value Limit values, fixed tare value and fixed analog output can be provided with new values (via configuration, see above, or via communication). In case these values are not stored, the old/original values remain unchanged. After mains failure, the old/ original values are re-activated again. The limit values and the fixed tare value can be stored via the configuration (step SAVE data) or via communication (communication address 'storeCofig', X90, X122).

As opposed to earlier PR 1711/xx versions, new entry parameters for increasing the accuracy were introduced, e.g. the hysteresis with no load on the load cells and the acceleration due to gravity during scale calibration without weight are taken into account. 1. Calibration is possible by means of weights or by entry of the mV/V values. Note: The SPAN (measuring signal for fsd) should be not smaller than 0.2mV/V for 5000d. Use higher 'mV/V' values for higher resolutions. 2. The following parameters must be entered as first parameters (recommendation): The f.s.d. value with decimal point and dimension. Subsequently, the step width must be selected. Decide if measuring must be done with or without filter. The remaining calibration parameters (menu:'measuring parameters') can be entered after calibration. The remaining parameters are: Test mode for the analog test, W&M mode for the printer, measuring time, zeroset range, time monitoring for taring, parameters for standstill detection, parameters for automatic zero tracking, overload range. 3. During calibration, a magnifier function is available, i.e. the weight in 'd' is displayed with an Increased resolution (multiplied by 100). 4.

With an insufficient number of counts, the presumed input voltage is increased to 2 or 3mV/V Sartorius 37 Calibration PR 1711 Operating Manual 5.4.1 Calibration by means of weights Generally, the use of calibration weights implies a high expenditure, however, it is the most accurate method for adjusting the scale, if the applied weight reaches almost the fsd. Calibration weights are only valid within the reach of the responsible weights & measures authorities. Alternatively, adjustment by means of calibrated liquid counter is possible. After step 3.

Frequently, calibration weights are available only for a small part of the full scale. If the scale can be loaded only half, the adjustment accuracy is not sufficient. In this case, the errors can be higher than by theoretical calibration of calibration points via span calculation or with step-by-step calibration. With step-by-step calibration, a sufficient weight value for scale adjustment is only reached after several steps, whereby a relatively small calibration weight may be used. The value displayed with the calibration weight is noted and reconstructed by a suitable (non-volatile) material after removal of the calibration weight. Subsequently, re-apply the calibration weight and substitute the new display value, etc. The deviation total is higher than the error sum of each individual step. This is a step-by-step calibration procedure with calibration weights and auxiliary material. The advantage is that smaller calibration weights can be used for calibration. The procedure is: 1. Enter the f.s.d. value with decimal point and unit as described above. 2. The scale is discharged. Set the scale to zero. 3. Load the scale with the calibration weight and enter the 1st weight point (correct weight) with function [L] set span with current load. 4. - Remove the calibration weight and load the scale with auxiliary material near the calibrated point. Note the weight value. - Load the scale additionally with the calibration weight. 5. If a deviation is displayed now (sum of auxiliary material and calibration weight), select function [L] 'to set span with current load'. Now, enter the sum. This procedure ( 4 and 5) can be repeated using new auxiliary material, until the f.s.d. value was reached. Caution: An increased resolution * 100 is available with the magnifier function.

The JBUS protocol is used for data transmission in binary code from and to the PR 1711 SPM. Each data exchange includes two telegrams: a command from the PC to PR 1711 and a reply from PR 1711 to PC. Command Command PC Reply Reply PR 1710 Each telegram comprises four blocks: 1. device address 2. function code 3. data (addresses and values) 4. CRC check word Note: All 2-byte values (16-bit values/word) have Motorola notation. Sequence: MSB - LSB A reply is sent on each faultless command. A faulty command received by PR 1711 (e.g. parity error in the data or CRC error) is ignored. In this case, no reply is sent. The pauses between the individual characters in a command must not be longer than 3.5 times a character length. Otherwise, PR 1711 detects the early end of command. If the received command is faultless, but cannot be handled (e.g. faulty address, faulty data), reply is with an error telegram. A telegram to slave 0 is executed by all PR 1710 units, but not replied by anyone. 8.3.1 Function 1 or 2: read n bits Command Range Device address 1 byte 1...255 Function number 1 byte 1, 2 Address of 1st bit 2 bytes 0,8,16...
