The figure shows an overview of the functional buttons and their general function.
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 multi-
drop 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 Trans-
mitter 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 trans-
mitter 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 Transmit-
ter 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.
