5 1 Introduction Thank you for choosing an MJK Data Transmitter 795. A great effort has been put into developing a product, which complies with all demands. MJK Data Transmitter 795 is mounted in the field and with its digital in- and output and analogue input it is capable to receive and transmit most types of digital and analogue signals. From a built-in RS232 serial port, the MJK Data Transmitter 795 can communicate directly with other equipment i.e. a pc, PLC or a Scada system. MJK Data Transmitter 795 can with one click on the mouse or from a telephone call activate digital output and/or read in- and outputs, alarm signal type for the latest 9 alarms and all logged data. Display of a pumping station from a pc with the monitoring program MJK-Link. MJK Data Transmitter 795 can also be programmed to make a telephone call when there is an alarm and transmit the alarm as text to a pc or SCADA system and to a cell phone as SMS text. The Data Transmitter 795 has a bult in battery for telephone calls at power failure. All settings, alarms and logged data can be read in the display, from easy to use functionnal menus. MJK Data Transmitter 795 can be supplied in versions that communicates via a built-in GSM modem or telephone modem, or in versions for radio modem. MJK Data Transmitter 795 is easy to install and operate, but read the instruction manual carefully in order to make optimum use of the unit. You can allways contact your sales reprsentative or the MJK Automation Hotline in case of doubt or for guidance. Try also to log onto Versions MJK Data Transmitter 795 is as standard supplied in the following hardware versions: - 8, 12 or 16 digital inputs - 0,4 or 8 digital outputs - 4 analogue inputs - 1 or 2 RS232 ports The RS 232 ports is used as connection to MJK Pump Controller 704 and to connection of a PC for configuration or reading of data in the field for i.e. a portable PC or for configuration or reading of data, when the Data Transmitter 795 is used as data logger. 1.2 Communications protocols MJK Data Transmitter 795 can be connected to a distribution station either through a serial connection (RS232-RS 485), a built-in Hayes compatible telephone modem, a data radio or a GSM modem. Communication complies with one protocol which must be followed by master and slave. Data Transmitter 795 is always the slave, i.e. the Data Transmitter must receive a command before it can reply. MJK Data Transmitter 795 is supplied with Comli PLC-protocol as standard. The following historical data are available in this protocol: - Time counter on digital inputs, total, total today, total yesterday and the latest 24 hours, all with 1 hour interval. - Analogue values stored with 5 min. interval 24 hours back, and in the extended log with a user defined logging interval. An MJK Data Transmitter 795 with built-in modem can transmit alarms as SMS messages directly to the cell phone of employee on duty. 5

6 1.3 MJK-Link The Windows based program MJK-Link can be applied to monitor one or several MJK Data Transmitter 795. Via a PC with modem it is possible with MJK-Link to read values, modify setpoints and read datalogger for e.g. storm flow values. All settings in Data Transmitter 795 can be implemented via MJK-Link. Furthermore, MJK Link can be used to control the MJK Pump Comtroller 704. This facitily is used when e.g. MJK Data Transmitter 795 and MJK Pump Controller 704 is used together.

Up to 8 inputs are shown simultaneously F0 - Interlock, operation or alarm signal Menu F0 followed by 1 x 'down arrow' will display which signals that initiate the 9 programmable interlock sequences: 'A': alarm signal, '+': operation signal, '-': not in use F0 - Internal flag, operation or alarm signal Menu F0 followed by 2 x 'down arrow' will display which signals that are linked to the internal flags: If there are more than 8 inputs, the remaining inputs will be displayed by pressing one of the arrow keys: Note, that a delay period can be set for every digital input so that the digital input can go ON for a short period without triggering an eventual alarm. When the input is OFF, an empty field is shown. When the input goes ON, a flashing field is shown during the delay time, after which a field is shown constantly F2 - Digital outputs on/off Menu F2 displays whether the digital outputs are set ON or OFF: 'A': alarm signal, '+': operation signal, '-': not in use F0 - Limits, high/low Menu F0 followed by 2 x 'down arrow' will indicate which analogue inputs that are linked to a high/low alarm limit, and also if the limit will release an operational or alarm signal: 'A': alarm signal, '+': operation signal, '-': not in use F0 - Digital inputs, operation or alarm signal Menu F0 followed by 4 (and 5) x 'down arrow' display which digital inputs, that releases an operation or alarm signal: A delay period can be set for every digital output. This delay period must run out before the output are activated. When the output is OFF, an empty field is shown. When the output goes ON, a flashing field are shown during the delay time, after which a field are shown constantly F2 - Internal flag on/off Menu F2 followed by 1 x 'down arrow' will display the status for the internal flags. 'A': alarm signal, '+': operation signal, '-': not in use. 14

15 5.4 F3 - Limits - High/Low Menu F3 indicates if high and low limit is ON or OFF for the analogue inputs. The first four digits indicate if the high limit setting is exceeded and the last four digits indicate if the low limit setting is exceeded: F5 - Analogue input on Pump Controller 704 Menu F2 followed by 1 x 'down arrow' display the value of the analogue input on the Pump Controller 704 (if connected): A delay time can be set individually for each analogue input in that the the input can exceed the limit for a short period without activating an alarm. An empty square is displayed when the limit is not exceeded. When the limit is exceeded, a solid square is displayed. If a delay period is set, the square will flash during the delay period. 5.5 F4 - Analogue input value # Menu F4 indicates the value of the analogue inputs as a bargraph: Select the desired input with the arrow keys or the numeric keys F5 - Analogue input scaling Menu F5 indicates the value of an analogue input as a percentage and the ma signal and as a scaled value: Select the desired input with the arrow keys or the numeric keys. The scaled value is determined by the programming of the analogue input. If the value represents e.g. a level measurement in a tank, and the level normally varies between 2 m and 3 m, the analogue input will normally be programmed so 2 m corresponds with '200' (low value) and 3 m corresponds with '300' (high value). A level of 2,5 m will then give a scaled readout of 250 and 50 %. If the scaled value should be shown as '2,5', it is possible to set a divisor for each input. In this example the divisor should have the value 100. See also section 7. Please observe that the value is collected directly from the Pump Controller 704 and is not scaled. 5.6 F6 - Counter for inputs Whenever a digital input or an analogue high/low limit is active, it will be recorded by a counter.

When the alarm for one input has been ON one time it must be set to OFF before a new alarm from the same input is accepted as an alarm. If the alarm has not been reset and another 9 alarms occur, i.e. the first alarm become no. 10 and therefore will become invisible in the alarm list, this alarm will be reset automatically. A flashing square is shown when an alarm goes ON. If the alarm are being reset but is still active, a solid square is shown constantly. When the alarm goes OFF again, a square is shown constantly. By means of the arrow keys or by entering the alarm number, the status, type and timestamps for on and off time can be displayed. Whenever an alarm goes ON, the input number and start time will be recorded. Similarly, when the alarm is reset, the reset time is recorded, and when the alarm goes OFF, the end time will be recorded: 5.10 F# - Modem/Line status (Only for versions with built-in telephone modem or GSM modem.) Menu F# displays the status of outgoing alarm calls or incoming calls: The following is displayed during an incoming call: The following is displayed during an outgoing alarm call to one of the telephone numbers in the telephone number list: When Data Transmitter 795 interlocks another Data Transmitter 795 i.e. in order to perform a remote start or stop of a pump, the following is displayed: 'ID' indicates the ID number of the Data Transmitter itself. If the Data Transmitter are configured as a Master in a multidrop system, the 'ID' can also be the ID number of a connected Slave unit.

Please note, that DO1 and DO2 may be used by the pump controller function - see also section Operational or alarm signal on internal flag If the signal type is selected as internal flag it is possible to select if an internal flag should be an operational signal or alarm signal. 11 Programming of interlock With this function it will be possible for two Data Transmitters to send command to each other. E.g. one Data Transmitter can control a digital output on another Data Transmitter. Furthermore, if a Pump Controller 704 is connected to a Data Transmitter, the output relays on the Pump Controller 704 can be controlled by another Data Transmitter Interlock of this station This menu makes it possible to block remote commands from other Data Transmitters (substations) Dialout when alarm signal on internal flag Selct if the internal flag should release an alarm call attempt on an alarm Signal delay on internal flag This menu is used to set the period in which both input signals should be active in order to set the internal flag. Note, that interlock of a connected Pump Controller 795 also will be blocked. Use arrow keys and confirm with ENTER Interlock interval This menu is used to set the interval for how often other Data Transmitters should be dialed for remote control. The actual application and communication method is decisive for setting the interlock interval. As an example, in case communication are taking place through a dialed line, it would be expensive to exchange interlock commands between two Data Transmitters every 5 minutes, if it is about stopping a waste water pump in connection with an overrun. Use arrow keys and confirm with ENTER. The setting will be valid for all Data Transmitters (substations) that are being set to interlock in the following menus Selection of substation Select the Data Transmitter (substation) to be interlocked. Use arrow keys and confirm with ENTER.. 22

23 11.4 Interlock active / inactive Select if the previously chosen Data Transmitter (substation) should be interlocked. Use arrow keys and confirm with ENTER Start of interlock Select the signal initiating an interlock on the selected Data Transmitter (substation): The following signals are available: - internal flag digital input 1-8/12/16 - analogue limit HIGH analogue limit LOW system error - power failure output 1-2 As long as the signal is ON, all calls will take place in the interlock interval previously chosen. If the interlock interval is set to 10 minutes or more, the remote controlled output should be configured as time controlled with an ON-time set to more than 10 minutes (e.g. 15 minutes) to avoid a situation where the remote output is ON constantly caused by a communications error. (E.g. a broken telephone cable.) In this way it is ensured, that the output is switched OFF, if communications fail. On error-free communication the ON-timer on the remote controlled output will be initialized on every call, and with that the output will stay ON as long as the controlling signal is active. Use arrow keys and confirm with ENTER Stop interlock Select the digital signal that - when switched OFF - will cause the Data Transmitter to call the other Data Transmitter and set an output OFF: The following signals are available: - internal flag digital input 1-8/12/16 - analogue limit HIGH analogue limit LOW system error - power failure output 1-2 Only one call attemt will be made. In case the same signal are selected as both start condition and stop condition, the stop condition will be when the digital signal goes OFF Receivers telephone / ID number Enter the telephone number / ID number of the Data Transmitter to be interlocked. Enter the ID number if radio modems are used. If the receiver is another Data Transmitter which is directly connected to the same multidrop line via the RS485 port, the ID number of the Data Transmitter preceeded with a minus. (The F key is used to enter the minus character.) Ex.: Data Transmitter ID 001 is supposed to remote control Data Transmitter ID 003: Enter the ID number "- 003" into Data Transmitter 001. If the receiver is another Data Transmitter which is communicating via data radio, the Data Transmitter's ID-nummer should be entered without a preceeding minus. 23

24 Please note, that only a Master Data Transmitter can directly remote control other Data Transmitters belonging to other clusters. Eks.: Data Transmitter ID 001 is supposed to remote control Data Transmitter ID 003: Enter the ID number "003" into Data Transmitter 001. Use the numeric keys and confirm with ENTER Receiver's output Select the desired digital output on the interlocked Data Transmitter: If the receiving unit is another Data Transmitter which is communicating via telephone/gsm modem, the telephone number to the Data Transmitter is entered here. Ex.: Data Transmitter no. 1 is supposed to remote control the Data Transmitter no. 3: Enter the telephone number " " into Data Transmitter no. 1. If the receiving unit is a Data Transmitter belonging to another cluster of Data Transmitters, the ID number / telephone number belonging to the Master in the cluster should be entered followed by the ID number of the desired Data Transmitter in the cluster. Eks.: Data Transmitter 001 in the lower cluster is remote controlling Data Transmitter 003 in the upper cluster: Enter telephone / IDnumber " " into Data Transmitter no

27 14 Programming of stormflow calculation Enter SMS message If the current telephone number type is selected as an SMS type, enter an SMS message/code of up to 8 digits: 14.1 Stormflow calculation Data Transmitter 795 can calculate the flow of an overrun via a digital input an an analogue input. Use the numerical keys and confirm with ENTER. If the message is entered via the keypad of the Data Transmitter, the message can only consist of numbers, but with MJK-Link it will be possible to enter text messages. The SMS message will be displayed on the cell phone with 'MJK 795' as headline followed by location and cause of the alarm and the SMS message. Test the SIM card in a cell phone if the SMS messages are not received. Also, check if the telephone number to the receiving SMS gateway is correct. Pager messages and SMS messages are delivered as telegraphic alarm to an external server, which implies that Data Transmitter 795 has no option to test that the telegraphic alarm has been received by the recipient Pause between calls Enter a pause between the call attempts to the telephone numbers on the telephone list: Use the numerical keys and confirm with ENTER. MJK 795 MJK 7062 MJK 501 In above example, MJK Pressure Transmitter 7062 provides the level signal to the Data Transmitter, and an MJK Level Electrode 501 is mounted where the stormflow starts. By this, the level measurement is set to zero and flow is calculated by means of the level signal. Usually, the Data Transmitter is connected to a Pump Controller 704 with a level transmitter with its measuring range adopted to the pump controller. The measuring range is normally higher than necessary for flow measurement, typically 10 m for the pump control and cm for flow calculation. The accuracy on the level measurement of the pump controller is as the total measuring range of the flow measurement. The Q/h curve of the weir must be entered in this menu such as the data transmitter can calculate the stormflow. Include as many Q(h) points as possible in order to obtain the highest possible calculation accuracy. Below is demonstrated Q(h) curve and Q(h) table for a rectangular weir with side contraction: Q(h) point no.: h[m] Q[m 3 ] 1 0,00 0,00 2 0,01 48,71 3 0,02 137,78 4 0,03 253,12 5 0,04 389,70 6 0,05 544,62 7 0,06 715,92 8 0,07 902,17 27

28 If these Q(h) values are entered in this menu, the resulting Q(h) curve will be as shown below, and the Data Transmitter will calculate the flow according to this curve: Number of Q(h) points In this menu the number of Q(h) points that are desired for the piece by piece linearization of the flow calculation. The number of Q(h) points can be set from 1 and 9, as the zero point value will be provided to be 0 m 3 /h. Use the arow keys and confirm with ENTER. Note, that Q MAX must be no more than m 3 / h Stormflow calculation in use Select if stormflow calculation should be used: Use the arow keys and confirm with ENTER Zero point input no. Select the input that the level electrode are connedted to. This input will activate the stormflow calculation Height value [h] for level point Enter the height [h] for the Q(h) point. The entered value MUST be higher than that for the previous Q(h) point. Use the numerical keys and confirm with ENTER Flow value [Q] for level point Enter the volume [Q] for the Q(h) point. Use the numerical keys and confirm with ENTER. The current flow value and the total stormflow value can be read in functional menu F9. See also section The following inputs can be selected: - 795: DI 1-8 / 12 / : High/low limit : Output Combi alarm 1-8 Use the arow keys and confirm with ENTER Level signal for flow calculation Select the input that provide the level signal for the stormflow calculation: The following inputs can be selected: - 795: Al : Level Use the arow keys and confirm with ENTER. 28

29 15 Programming of 702 ComTroller If one or more 702 ComTrollers is connected to the Data Transmitter as multidrop units on the RS485 port, they can all be programmed via the Data Transmitter's keyboard and display. (The Data Transmitter must be the Master in the cluster.) 15.1 Select 702 Enter the ID number for the desired 702 ComTroller: Use the arow keys and confirm with ENTER. The Data Transmitter will now attempt to establish a connection with the selected 702 ComTroller: If the selected 702 ComTroller does not respond, the connection attempt can be interrupted by pressing the key, whereafter another ComTroller can * be selected. When the selected 702 ComTroller responds, svarer, the Data Transmitter's display and keyboard can now be used for remote programming of the ComTroller: The function will be interrupted by pressing the * key. 29

30 16 Alarms 16.1 Operational or alarm signal The digital inputs can be set to be either a operational or alarm signals. An operational signal defines a non-critical condition, e.g. a signal that only need to be recorded in the operational log. It would typically be a signal indicating whether a pump is running or not. An alarm signal is a signal, which normally is not active and only becomes active when critical conditions occur, e.g. a thermal overload signal from a pump. Furthermore, an alarm signal has memory and reset, i.e. when the alarm signal becomes no-active, the previous active condition are remembered. This previous active condition must be reset by the user before a new change to active condition will be accepted as an alarm signal. For both types of signals are applied that both the number of changes to active condition and the period of time where the signal has been active will be recorded in the alarm record Alarm calls If 'Call on alarm' is selected, the Data Transmitter will call all the numbers in the telephone list starting with the first entry. Proceeding to the next number in the list will take place after a preset period of time -'Pause between calls'. See also section 13. If a call is made to a modem on a SCADA main station, it will be the main station's task to reset the alarm and stop the dialout routine. If call are made to a pager or telephone, the dialout routine is stopped by making a call to the Data Transmitter. A tone will be heard in the handset. This will not reset the alarms, but only stop the dialout routine. See also section If another alarm occur during the dialout routine, the dialout routine will continue, and the new alarm will be reported in to the next number in the telephone list. Versions with radio modem transmit all alarms to the main station (ID no. 0) Reset of alarms When an alarm signal becomes active, it will be visible in menu F8 (see section 5.8). Whenever a digital alarm signal becomes active, the alarm will be present in menu F8.1. This menu will show the alarm type and start time together with a flashing symbol ' '. The symbol will flash as long as the alarm has not been reset, and the symbol will appear solid when the alarm has been reset but still active. The symbol disappear when the alarm has been reset and the alarm signal is inactive. When the symbol disappear, the stop time for the alarm is displayed instead of the start time. In order to reset an alarm from the front panel of MJK Data Transmitter 795, the menu F8 must be shown. Then use the arrow keys to select the alarm to be reset. Reset the selected alarm by pressing ENTER. The symbol ' ' will then appear solid if the alarm signal is still active or disappear, if the alarm signal is no longer active. An alarm can also be reset from a SCADA system. An alarm signal must have been reset and change from non-active to active condition in order to be visible in the alarm list again. This means that if you do not want to receive the same alarm call several times on the SCADA station, the alarm should not be reset. The Data Transmitter will then stop further alarm calls concerning that particular alarm even if the alarm signal change from non-active to active condition Automatic reset of alarms If an alarm has not been reset, and another 9 alarms occur, meaning that the not yet reset alarm becomes no. 10 and therefore no longer will be visible in the alarm list, the alarm will be reset automatically, if the function 'Automatic reset of alarms' has been activated.

51 Appendix B Appendix B1 Maintenance In case the function 'Alarm call at power failure' is acticvated, it is recommended to exchange the built-in accumulator yearly. Beyond this, MJK Data Transmitter 795 require no particular maintenance. Check the accumulator by disconnecting the power and check if the Data Transmitter is able to perform a dialup sequence in order to transmit a power failure alarm. When the power is disconnected, the display backlight will disappear immediately. If 'Alarm call at power failure' is deacticvated, the display will be turned off completely after sec. If 'Alarm call at power failure' is acticvated, the Data Transmitteren will start to dial the phone numbers in the telephone list in a period of max. 5 minutes, and then the Data Transmitter will shut down. B2 Service codes Data Transmitter 795 are equipped with functions that should not be operated by the end user. Always contact MJK Hotline before the service codes are used! B2.1 Universal access code If the access code is unavailable, the acces code can always be used. B2.2 Forced setup without reset of datalogger If this code is used, the user will be forced to go through all settings. The logged data will not be erased. Enter F 0 followed by See also separate documentation for GSM/GPRS option. B2.6 Total reset This code give access to a TOTAL RESET. Enter F 0 and B3 Software upgrade The software is stored in EPROM, that just need to be exchanged for upgrading. When the EPROM is exchanged, all basic settings and all logdata will be preserved, if the old software are version and onwards. All basic settings and logdata will be lost when upgrading software versions before : Read first the instruction that came with the new EPROM. 2: Disable the function 'Alarm call at power failure'. See section : Disconnect the power supply to the Data Transmitteren. 4: Remove the front panel by unscrewing the 4 retaining screws in each corner and flip it out of the cabinet. Note: DO NOT withdraw the flat cable to the lower PCB! Note the notch in the EPROM! B2.3 Forced setup including reset of datalogger If this code is used, the user will be forced to go through all settings. All logdata will also be erased! Enter F 0 followed by B2.4 Baud rate and communication method This code give access to menus for setting the baud rate for the serial port and to select communication method (GSM/GPRS/Pager/ internal modem etc.). Enter F * followed by B2.5 Activation of SIM card for GSM/GPRS modem Enter F # followed by * * 0 5 *. 5: Remove the old EPROM. Mount the new EPROM in the socket marked 'IC4' (see illustration above). Make sure the EPROM is mounted in the correct orientation! 6: Reassemble the front and connect the power source to the Data Transmitter. 7: All basic setting must be confirmed. It is very important that the hardware setup settings are correct! Data Transmitter 795 is now ready for operation. 51
