Data Transmitter 795

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.

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 http:// www.mjk.com.

1.1 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

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.

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.

An MJK Data Transmitter 795 with built-in modem

can transmit alarms as SMS messages directly to

the cell phone of employee on duty.

M795GB0503

- Analogue values stored with 5 min. interval 24 hours back, and in the extended log with a user defined logging interval.

14.1 Stormflow calculation

Data Transmitter 795 can calculate the flow of an overrun via a digital input an an analogue input.

MJK 795

MJK 501

MJK 7062

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 10-20 cm for flow calculation. The accuracy on the level measurement of the pump controller is as the total measuring range of the flow measurement.

M795GB0503

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.

16 Alarms

Data Transmitter 795

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.

16.2 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 15.3.1.

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.

16.3 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.

15.3.1 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. See also section 6.11.

Versions with radio modem transmit all alarms to the main station (ID no. 0).

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 20 - 40 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 1 1 1 1 can always be used.

See also separate documentation for GSM/GPRS option.

B2.6 Total reset

This code give access to a TOTAL RESET.

Enter

F 0 and 2 0 4 5.

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 800400 and onwards. All basic settings and logdata will be lost when upgrading software versions before 800400.

1: Read first the instruction that came with the

new EPROM.

2: Disable the function 'Alarm call at power

failure'. See section 6.8.

3: 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!

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.

F 0 followed by 1 2 3 4.
