been programmed, o it finds that the internal memory has been altered, and it is unable to recover
correctly the data, then it will automatically go to the programming modes in order that the correct data
can be entered. All the data is stored in a non-volatile memory which keeps the data even in the
absence of the mains supply.
When the MT-02 has been previously programmed the MODE "0" will automatically appear
except when there has been a failure of the mains voltage during a batching process, and then it will
automatically go to MODE "1" and the display will blink.
2.3 Basic Configuration of the equipment
To program the MT-02 we must start from MODE "0", from this mode we can enter the different
programming modes.
There are two basic pieces of data which must be introduced for the equipment to be able to
work. At first we must enter the litres per pulse, for which we press the "ENTER" [5] push-button and the
MODE Indicator will change to "L", indicating that we are in the litres per pulse programming mode.
There are two integer numbers and five decimal points which means that we have a limit of 99.99999
litres per pulse with a resolution of 0.01 ml per pulse. If the flowmeter is specified in "pulses per litre", we
must calculate the reciprocal of the value in order to change to litres per pulse, for example, if we have a
flowmeter which gives 450 pulses per litre, the pulses per litre will be 0.00222 and this number must be
entered in this program mode.
When the litres per pulse programming mode is entered the least significant digit blinks to
indicate that one can change the value of this digit. To change the value of a digit we use the " ∆" [6]
push-button. Every time we press this push-button the value of the digit is increased until it reaches nine,
and then goes back to zero. By pressing the "ENTER" [5] push-button we go to the next digit to modify.
If the "PROG." [4] is pressed then the value on the display will be saved in the memory and the
instrument will go back to MODE "0". If we press the "ON/OFF" [3] push-button while in a programming
mode then the instrument will go back to MODE "0" but the data on the display will not be saved in
memory and it will keep its previously programmed value. The MT-02 will not accept "0000000" as a
valid value and will not come out of a programming mode unless it has a valid value.
3 BATCHING
3.1 Entering the preset value
Starting from the "0" MODE, by pressing the "PROG." [4] push-button we can enter in the mode
to program the preset value in litres for batching, and the MODE Indicator will change to "P" to indicate
the Preset programming mode.
The use of the push-buttons is identical as for programming the litres per pulse. In this mode we
must introduce the litres required for the batch.
3.2 Batching
From mode "0" press the "ON/OFF" [3] push-button to enter the batching mode. When the
ON/OFF" [3] push-button is pressed the partial counter will be cleared, the mode indicator will go to "1"
and the relay will be activated to start the batch.
While in the batching mode, if the ON/OFF" [3] push-button is pressed, the relay will be
disactivated and the display will start to blink, indicating that the process has been stopped before
finishing.
