Multi-functional outputs
The fl ow meter is equipped with two multi-functional outputs. Relay or optotransistor contacts are connected to BIN1
terminals, while BIN2 terminals are used for optotransistor only. Use jumper NC-OC-NO above BIN1 terminals to set their
function.
a) Output works as optotransistor
b) Relay contacts are normally open
c) Relay contacts are normally closed
Outputs can function as:
a) Pulse transmitter
• of total volume in positive direction imp V+
• of total volume in negative direction imp V-
• of total volume in both directions imp V
b) Status output
B-1. Pulse setting
Volumes 0.1 l, 1 l, 10 l, 100 l, 1 m3, 10 m3, 100 m3 and widths 10 ms, 20 ms, 40 ms, 80 ms, 160 ms, 320 ms, can be assigned to
transmitted pulses.
WARNING
THE FLOW METER TRANSMITS THE NUMBER OF PULSES CORRESPONDING TO THE LIQUID QUANTITY
FLOWED DURING A MEASURING CYCLE OF 640 MS. PULSE CAN BE ASSIGNED ONLY SUCH VOLUME
AND WIDTH SO THAT THE NUMBER OF TRANSMITTED PULSES DURING TIME UNIT IS REAL! INCORRECT
SETTING IS INDICATED BY AN ERROR MESSAGE. DISPLAY SHOWS THE CODE E5.
1. Use the cursor keys to select the option
PULSE OUTPUTS
from the main menu and confi rm your selection with the
EXE
key. A sub menu will be displayed.
2. Select
PULSE WIDTH
under options ms/imp1(2) and assign required volume to the pulse under option l/imp (2).
3. Select option
OUT1
(output to terminals 1 - 2) or
OUT2
(output to terminals 3 - 4) and confi rm your selection with the
EXE
key.
4. Select
V+
from menu (output transmits pulses only for fl ow in positive direction),
V-
(output transmits pulses only for fl ow in
negative direction) or
V
(output transmits pulses for both directions) and confi rm by pressing the
EXE
key.
5. Select the
RETURN
option to complete the set-up.
The instrument will ask if you want to save the new parameters by displaying the text
