Supply moisture meter and sound level meter,etc.

M73

Window to setup the lower limit of flow rate for Alarm#1.

When the flow rate is below the set value, Alarm#1 equals ‘on’

M74

Window to setup the upper limit of flow rate for Alarm#1.

When the flow rate is above the set value, Alarm#1 equals ‘on’

There are two alarms in the flow meter, and every alarm can be pointed to alarm output devices such as the BUZZER or OCT output or RELAY output. For example, if you want the Alarm#1 is to output by the OCT circuit, you need to set M78 at selection item 6.

M75

Window to setup the lower limit of flow rate for Alarm#2.

M76

Window to setup the upper limit of flow rate for Alarm#2.

M77

17.ON/OFF viaRS232   18.Daily Timer (M51)  19.Timed alarm #1 

20. Timed alarm #2     21.Batch Totalizer Full  22. M51 Timer

23. Key Stroking ON    24.Disable BEEPER    25.Close buzzer

M78

OCT (Open Collect Transistor Output)/OCT1 setup

By selecting a proper input source, the OCT circuit will close when the trigger event occurs. The available trigger sources are:

0. No Signal         1. Poor Signal    

2. Not Ready(No*R)  3. Reverse Flow     4. AO Over 100%   

5. FO Over 120%    6. Alarm #1         7. Reverse Alarm #2

8. Batch Control     9. POS Int Pulse     10.NEG Int Pulse

11.NET Int Pulse    12.Energy POS Pulse  13.Energy NEG Pulse

14.Energy NET Pulse  15.MediaVel=>Thresh  16.MediaVelo

17.ON/OFF viaRS232  18. Daily Timer (M51)  19.Timed alarm #1 

20. Timed alarm #2     21.Batch Totalizer Full  22. Periodically M51 Timer

23. Oct Not Using,      24. FO output         25. Close OCT output

The OCT circuit does not source voltage at its output. It must be connected with an external power and pull-up resistant for some occasions.

When the OCT circuit is close, it will draw current. The maximum current shall not be over 100mA.

Attention: the maximum voltage applied to OCT can not be over 80 volts. 

M79

Relay or OCT2 setup

By selecting a proper input source, the RELAY will close when the trigger event occurs

The available trigger sources are:

0. No Signal       1. Poor Signal    

2. Not Ready(No*R)  3. Reverse Flow     4. AO Over 100%   

5. FO Over 120%     6. Alarm #1        7. Reverse Alarm #2

8. Batch Control      9. POS Int Pulse    10.NEG Int Pulse

11.NET Int Pulse     12.Energy POS Pulse  13.Energy NEG Pulse

14.Energy NET Pulse  15.MediaVel=>Thresh  16.MediaVelo

17.ON/OFF viaRS232  18. Timer (M51 Daily)  19.Timed alarm #1 

20. Timed alarm #2     21.Batch Totalizer Full 

22. Periodically M51 Timer  23. Disable Relay  24.Close relay output

The RELAY is of SPST (Single pole, single throw) type. It is rated for 110VAC max and has a current rating of 0.5A resistive load.

It highly recommended that a salve relay to be utilized whenever a large resistive load or inductive load is to be controlled.

Note. In order to make the user interface compatible with the former version7, the name RELAY was used other than OCT2, but in fact it is an OCT output.

M80

Window for selecting the trig signal for the built-in batch controller. Available trig sources:

0. Key input         (press ENT key to start the batch controller)

1. Serial port

2. AI3 rising edge     (when AI3 receives 2mA or more current)

3. AI3 falling edge     (when AI3 stop receiving 2mA or more current)

4. AI4 rising edge     (when AI3 receives 2mA or more current)

5. AI4 falling edge    (when AI3 stop receiving 2mA or more current)

6. AI5 rising edge     (when AI3 receives 2mA or more current)

7. AI5 falling edge    (when AI3 stop receiving 2mA or more current)

8.Timer periodically   (define the start time and interval time in M51)

9.Timer daily        (define the start time and interval time in M51)

For the input analog current signal, 0 mA indicates “0”, 4mA or more indicates ‘1’.

By selecting item #8, the batch totalizer can be started periodically by the internal timer located at Menu51. When the batch totalizer is full, a signal which indicate the batch is full can be direct to either the OCT or the RELAY terminals to stop the pump or other devices.

By selecting item #9, the batch totalizer could act as totalizer witch runs for only a period of the day so that a alarm signal could be produced if the total flow during that time period is over a certain amount of. For example, if you want a alarm signal which stand for the total flow is over 100 cubic meters during the period of every day from 20:00 to 06:00, setups is like

  M51 start time =20:00:00

  M51 interval  =10:00:00

  M51 log times =9999    (means always)

  M80 select item #9

  M81 input 100         (Unit is defined in M30,M31,M32)
