ComTroller 702
1 General
MJK Comtroller 702 is developed for control and
surveillance of small pumping stations and water
borings. Comtroller 702 is a complete unit with inand outputs, CPU, data logger, real time clock and
communications port for data transmission on
owned lines.
Comtroller 702 is an advanced product based on
the experience from the thousands of monitoring
systems delivered during the past 15 years.
Comtroler 702 is an advanced product for on-site
mounting with control, data logging storing and
transmission of analog and digital measuring values
to be used in both small and large SCADA systems.
Comtroller 702 is typically arranged in clusters
where each Comtroller is connected to a 2-wire
communications line. A Data Transmitter 795 is
then connected as a master communications unit.
Every single Comtroller 702 can be called
individually by their different ID numbers, and the
Data Transmitter 795 simply handles the data
transmission via a telephone modem, a radio
transceiver or a GSM modem directly to the
SCADA system.
Comtroller 702 has all necessary functions built in
such as interface to measuring and control
equipment, a data logger, counters and data
transmission. Comtroller 702 is programmed directly
from a PC, from the SCADA system or via a MJK
Data Transmitter 795 as a master communications
unit.
Comtroller 702 is a compact unit containing all
necessary functions such as communications interface and drivers, software, I/O ports, data storage
memory and RS485 repeater.
Comtroller 702 is simple and economic to utilize
since it contains all necessary facilities to decrease
the number of external components needed to
form a complete unit for control, monitoring and
data transmission.
The RS 232 port is used for interconnection
through external modems, GSM-modems or a PC
for configuring or data readout.
1.2 MJK-Link™
The MS-Windows™-based program MJK-Link™
can be used for monitoring one or more Comtroller
702. It is possible with MJK-Link™ via a PC with a
modem to read realtime values, stored values for
investigation of storm flows and changing of
setpoints.
This manual deals with MJK Comtroller 702 with
Comli-protocol for telephone modems. GSMmodems, RS 485 on owned lines, powerline
modems and closed radio networks.
Screen dump from the monitoring program MJK-Link™, where a pumping station with 2 pumps, monitored and
controlled by a Comtroller 702 are operated in a window that appears as the well-known MJK Data Transmitter 795.

ComTroller 702
2 Operation
A Comtroller 702 can be considered as a Data
Transmitter 795 without display and keypad and
with a built-in pump controller. Instead of display
and keypad the Comtroller 702 is operated via the
serial communications port from either a PC with
MJK-Link™ or a Data Transmitter 795.
MJK-Link™ is used for monitoring and operation of
Comtroller 702. The Comtroller 702 will appear
exactly as a Data Transmitter 795 in MJK-Link™
with its well-known 2 x 24 character display and
keypad. The kepad is simply operated via the PC
keyboard.
MJK-Link™ makes it possible to upload,
download and save the settings for one or more
Comtroller 702's interconnected on the same multidrop communications æline. It is thus possible to
download the setting from Comtroller no. 9, save
the setting as i.e. "Pumping station at the bend"
and upload the setting to Comtroller no. 14, placed
at "Pumping station at the pond". It is also possible
to name the in- and outputs individually.
A Data Transmitter 795 with Master-software can
also be used to operate a number of Comtroller
702's on the same multidrop communications line.
The desired Comtroller 702 is selected by entering
the corresponding ID-number on the Data Transmitter 795, after which the selected Comtroller can
be operated exactly as if it were a Data Transmitter
795. At the same time the Data Transmitter 795
contains a surveillance function that calls the
Comtrollers one by one over an adjustable interval.
If a Comtroller does not respond, the Data transmitter will send a system alarm.
A Data Transmitter 795 also manages
comunication to the SCADA system, MJK-Link™
etc.
A typical installation covers five to 20 Comtrollers in
an area where communication takes place via
owned lines or with MJK PowerLine modems
through the mains supply network.
On ie. the main pumping station, a Data Transmitter 795 with master software is installed, which will
be able to send alarms via a telephone- or GSM
modem to the SCADA system and/or one or more
mobile telephones as SMS messages.

3 Menus
3.1 F0 - Unit type/ID, software version, clock
and protocol type
Menu F0 show the MJK unit type, protocol type,
program version and date / time.
MJK 702 : 3 COMLI 830802
16:07:29 24/10/01
In above example, the Data Transmitter is
connected to a Comtroller 702 with unit ID no. 3.
The Unit ID no. is set binary by means of 8
switches on the front panel. (All OFF = 0 - All ON =
255.) Note! The unit ID no. must be set within the
range 1 to 247.
3.2 F1 - Inputs on/off
In menu F1 is shown whether the digital inputs are
ON or OFF.
INPUTS 1 2 3 4
ON : OFF:
The first two fields indicate if the high limits are
exceeded and the last two show if the low limits
are exceeded.
LIMITS HIGH/LOW 1 2
3 4 5 6 1 2
ON : OFF:
A delay time can be set individually for each analog
input allowing the input to exceed the limit
momentarily without i.e. activating an alarm. (See
section 5.)
If the analog input are within limits, the field will be
empty. If the limits are exceeded, the field will flash
during the delay time. When the delay time has
expired, the field is shown in a steady state.
3.5 F4 - Analog inputs #
Menu F4 shows the immediate value of an analog input as a horizontal bar formed of up to 24 fields. If the
input signal is 4 (0) mA (see also section 5.2), none of
the fields is lit (0 %). If the input signal is 20 mA, all 24
fields is lit (100 %).
In above example, DI no. 1 and 2 are ON while DI
3 and 4 are OFF.
A delay time can be set individually for each digital
input in order to allow the input to go ON without
activating i.e. an alarm. (See section 6.)
When the input is OFF an empty field is shown.
When the input is ON, the field will flash for the
duration of the delay time. When the delay time
has expired, a full field will be lit.
3.3 F2 - Outputs on/off
Menu F2 show the status of the digital outputs.
OUTPUTS 1 2 3 4
ON : OFF:
In above example, DO no. 1 and 2 are ON while
DO 3 and 4 are OFF.
A delay time can be set individually for each digital
output in order to delay the activation of the
corresponding output relay. (See section 7.)
When the output is OFF an empty field is
shown. When the output is ON the field will flash
for the duration of the delay time. When the delay
time has expired, the output relay is activated and
the field will be shown in a steady state .
ANALOG INPUT NO #
Select the desired analog input with the arrow
keys or by keying the corresponding input number
(1 - 2).
3.6 F5 - Analog input scaled
Menu F5 shows the immediate value of an analog
input in digits rather than a horizontal bar as in the
previous menu.
The first set of digits read out the signal value as
the percentage between the low mA value (0/4
mA) (see also section 5.2) and the high mA value
(20 mA). The next set of digits read out the same
signal multiplied with a programmable scaling factor.
The readout scaling is determined by programming
the desired readout range corresponding to the
low mA value (0 / 4 mA) and the high mA value (20
mA) respectively. If e.g. a tank level is measured,
and the level varies between 2 metres and 3
metres, the low mA value is set to correspond to
"200" and the high mA value is set to "300". A level
measurement of i.e. 2,5 metres will corespond to a
signal value of 50 %, resulting in a readout of "250"
(See section 5.3 - 5.4)
3.4 F3 - Limits high/low
Menu F3 indicate if the high and low limits for the
analog inputs are exceeded.
M702GB/0110 Rev. 111001
ANALOG INPUT NO #
50 % SKALERET 250
Select the desired analog input with the arrow
keys or by keying the corresponding input number
(1 - 2).

If the ENTER button is keyed, the counter present
in the display - and only this - will be reset.
3.8 F7 - Hour
Menu F7 show the total time the digital inputs and
the analog high limits and low limits have been set
ON.
The ON time is registered continuously; meaning
that if an input or limit is set to OFF and later is set
back to ON, the timer continues from its previous
value.
HOUR : AI # LOW
RESET: ENTER 2:43
Every single input / high and low limit has its own
counter. Use the arrow keys to change the readout
between:
- digital input 1 - 4

7.6 Special functions for the digital outputs
(This menu is only accessible if 'Fixed' is selected
as described in section 7.3.)
It is possible to perform AND logic sequences by
means of the digital in- and outputs.
For example the Comtroller 702 can be programmed to activate a digital output when 2 digital
inputs are ON. The digital signals can also derive
from exeeding a limit value on an analog input - or
a combination of a signal caused by exceeding a
limit value and an active digital input.
The following signals can be combined:
- digital input 1 - 4
- analog limit HIGH 1 - 2
- analog limit LOW 1 - 2
- combi alarm 1 - 8

8 Interlock
When interlocking two MJK Comtroller 702's they
will communicate with one another. In this way one
data transmitter can control a digital output
remotely on the other.
8.1 Interlock in use yes/no
Select whether the interlock function is to be used
or not.
Use the arrow keys to select and confirm with
ENTER.
8.2 Start of interlock
Select the signal which - when it goes ON - will
make the Comtroller call the other Comtroller and
set an output ON.
Use the arrow keys to select and confirm with
ENTER.
The following signals can be selected:
- digital input 1 - 4
- analog limit HIGH 1 - 2
- analog limit LOW 1 - 2
- combi alarm 1 - 8
As long as the signal is ON, calls will take place in
10 minutes interval. The remote controlled output
must therefore be set to "time controlled" and
configured with an ON-time of more than 10
minutes (e.g. 15 min.), thus securing that the output is not constantly ON if an error situation should
occur (e.g. a broken telephone cable). This way
the output is certain to go OFF even in the case of
communication failure.
At faultless communication the ON time of the
remote controlled output will be initialised at each
call and the remote controlled output will stay ON
as long as the controlling signal is active.
8.3 Stop interlock
Select the signal which - when it goes ON - will
make the Comtroller call the other Comtroller and
set an output ON.
Use the arrow keys to select and confirm with
ENTER.
The following signals can be selected:
- digital input 1 - 4
- analog limit HIGH 1 - 2
- analog limit LOW 1 - 2
- combi alarm 1 - 8
Only one call attempt will be made. If the same
signal is chosen both as start and finish condition
for the inter lock, the finish condition will be when
the signal goes OFF.

10 Telephone list for alarms
(This section applies is only
10.1 Telephone number 1-9
In this menu up to 9 telephone numbers are keyed
in which will be dialed chronologically at an alarm
situation.
Press key 1 - 9 to select the number which is to be
changed, press ENTER to change the receiver
type (PC, Pager, ph [phone], SMS), press ENTER
to correct the number - key in the number with the
numerical keys, and confirm with ENTER.
After keying in the telephone number the MENU
key must be used in order to move on to the next
menu, the ENTER key will be of no use here.
When calling through a switchboard, a * can be
used for awaiting a dialtone. A * gives a pause of 2
seconds. I.e. 0*00454556,656##23 means:
First dial 0 to get an external line, await the dialling
tone, then dial 0045 45560656, wait for 4 seconds,
then dial 23.
In the parenthesis following the number, it is stated
which type of reciever the call has been made to.
When calling a modem set to 1 [PC]. When calling
a beeper / pager set to 2 [Pager]. When calling an
ordinary telephone set to 3 [PHONE].
10.2 Key In PS Message
If a telephone number has been chosen as a PS
number, a message of up to 8 digits can be typed
in (e.g. the telephone number of the data transmitter), the message can be different for the various
telephone numbers. The message for the pager is
shown in the pager display together with a code
for the alarm, which has caused the call.
E.g. a datatransmitter with telephone number
455660656 where digital input 5 has an active
alarm input; will give the following alarm message
in the PS:
05-45560656
The configuration is stored in a EEPROM which is
not lost even if the supply is disconnected
10.3 Entering SMS messages
Up to 8 characters can be entered here if a receiver type is selected as an SMS type.
It is possible to enter digits as an SMS message
via Data Transmitter 795, and with MJK-Link32™ it
is also possible to enter a text.
The SMS message will be shown on the cellular
phone with "MJK-702" as the opening text,
followed by the cause of the alarm and the
corresponding SMS message. If a GSM modem
are used as communications unit, the pager
message will be changed to an SMS message.
Check the SIM card in a cellular phone if no SMS
message is transmitted, and check, if the phone
number to the SMSC-server is correct. The phone
number to the SMSC-server depends on the GSM
network service provider.
When sending SMS messages and pager
messages, it is not possible to check whether the
message is sent to the recipient or not, since the
messages are delivered to an external server.
The alarm codes are:
01 : Digital input no 1
02 : Digital input no 2
03 : Digital input no 3
04 : Digital input no 4
21 : Analog limit no 1 LOW
22 : Analog limit no 2 LOW

11 Programming of storm flow
calculation
11.1 Stormflow calculation
Comtroller 702 can be applied for calculation of
storm flow by means of one digital and analogue
input. Generally Comtroller 702 is applied to a level
meter with measuring range adapted to the pump
controller. This measuring range is normally
considerably higher, than what is necessary for
flow measurement, generally 10m for the pump
controller and 10-20cm for flow calculation. The
accuracy of the pump controller’s level
measurement is as the whole measuring range.
The data transmitter will compensate by means of
a digital input. An electrode relay, e.g. MJK 501
and a level electrode e.g. MJK 222860 are
applied.
The level electrode is applied where the storm flow
starts. By this, the chosen level meter will be in
zero position and calculate flow on the level signal.
This will improve the accuracy 10 to 15 times in
short term. The system provides a simple and
accurate measurement to a reasonable price.
11.2 Stormflow calculation in use Yes/no
Indicate application of stormflow calculation.
Use the arrow keys and confirm with enter key.
11.3 Zero-point DI #
Indicates the digital input that sets zero-point and
activates the flow calculation.
Choose between AI 1-2
Use the arrow keys, confirm with ENTER.
11.5 Key in the number of Q(h) points (1-9)
Indicate the number of Q/H points for single
linearization of the actual flow. The number can be
set between 1 and 9, as zero-point is set to a flow
3
of 0 m
/h.
12 Combi alarms
It is possible by means of a combi alarm to set off an
alarm call when 2 digital signals is activated
simultaneously. A digital signal can derive from a
digital input or from a limit alarm.
12.1 Combi alarm #
Use the arrow keys or enter 1 to 8 to select the
combi alarm to be programmed.
12.2 Combi alarm in use
Select if the combi alarm should be used. Use the

activate a combi alarm. The following digital signal
can be selected:
- digital input 1 - 4
- analog limit HIGH 1 - 2
- analog limit LOW 1 - 2
- power failure
12.4 Signal delay
Select the delay for the combilalarm. The delay
time is the time the two digital signals should be
active at the same time to set a combi alarm.
The format for the delay period is MM:SS.
Use the arrow keys (double arrow for minutes and
single arrow for seconds) or the numeric keys and
confirm with ENTER.
12.5 Combi alarm calls

13 Alarms
13.1 Operational or alarm signal
The digital signals can be chosen as either
operational or alarm signals.
A operational signal can be defined as non-critical,
i.e. a signal, that one want to be registered.
Typically a signal, that indicate if a pump is running
or not.
An alarm signal is on the other hand a signal, that
normally is inactive and only will be active, when a
fault condition occurs. A thermal cutout on a pump
is a typical alarm signal.
Alarm signals has memory and reset, i.e, when the
alarm signal becomes non-active, it will be
memorized that the signal has been active. The
"active" state must be reset by the user before a
new active signal can be accepted as an alarm
signal. For both types of signals applies that both
the number of active conditions and the time frame
within the signal has been active, will be
registered.
13.2 Alarm calls
If the function "Alarm - call by telephone" is
selected (see section 6.5), the Comtroller 702 will
start a call routine by making a call attempt to the
first number in the phone list, then the next number
etc.
There will be a pause between the call attemps.
See also section 10.
When dialing to a telephone modem, it will be the
SCADA terminal that will be responsible for
resetting the alarm and stop the call routine.
When dialing a pager or telephone, the call routine
must be stopped with a telephone call back to the
Comtroller. This procedure will not reset the alarm,
only stop the call routine. If an alarm occurs during
the call routine, the call routine will not stop, i.e.
the new alarm will not be reported until the next
call succeeds.
The telephone list is not used if the RS485 port are
used for communication (via radio modem,
Powerline modem owned lines etc.). All alarm calls
is sent to the Master communications unit.
13.3 Reset of alarms
When a digital alarm signal becomes active, it will
be displayed in function menu F 8.1. Function
menu F 8.2 will display the input number and type
causing the alarm, the corresponding alarm designation, the immediate status of the alarm and the
time when the alarm was set.
indicating the status. The symbol flashes until the
alarm is registered which makes the symbol
permanently lit. The symbol stays lit until the alarm
signal is no longer active, then the signal disapears
and the stop time will show instead of the start
time.
To reset an alarm directly from the Data Transmitter keyboard, the display must show indication
F8.1. With the arrow keys the alarm to cancel is
chosen then press ENTER. The symbol will then
stop flashing and the alarm is registered.
An alarm can also be reset from the SCADA station via modem. This is carried out via the
communications protocol. If you do not wish to
have more calls on the account of a specific alarm
signal, it can be left unregistered, and there will be
no more calls, even if the signal changes from not
active to active.
If the alarm is not registered, and a further 9 alarms
occur, i.e. the unregistered alarm becomes no 10
the alarm will be cancelled.
13.4 Special factory codes
Comtroller 702 is provided with functions which
should not be served by the final user.
13.5 Access code
If the access code is lost, the code 1111 can always
be used.
13.6 Setting up the serial port
If the service code 2222 is used, it gives access to
adjustment of the baud rate. Contact the technical
hotline for help.
13.7 Forced reset to factory settings
It is possible to reset all settings to factory setting,
meaning that all settings must be made once
again. Use service code 2045.
13.8 SMSC telephone numbers
SMS-beskederne from Data transmitter 795 and
Comtroller 702 is sent to an SMSC server on the
following telephone numbers:
Denmark: (0045) 43 62 52 50
Nederlands: (0031) 653 14 14 14
