pulse output is connected to an internal Buzzer. With
every 0.1 cubic meter of flow, we need the BUZZER to
beep for a while. In order to achieve this, the following
steps must be performed:
1) Select the Cubic Meter (m3) unit in window M32.
2) Select the Multiplier factor as ‘2. X0.1’ in window
M33.
3) Select the output option ‘9. POS INT Pulse’ in
window M77. (INT stands for totalized )
3.17 HOW TO PRODUCE AN ALARM SIGNAL
There are 2 types of hardware alarm signals that are
available with this instrument. One is the Buzzer, and
the other is the OCT output.
The triggering sources of the alarming events for
both the Buzzer and the OCT output could be:
1) There is no receiving signal
2) The signal received is too weak.
3) The flow meter is not in normal measurement modes.
4) The flow direction is changed.
5) Overflow occurs at the Frequency Output
6) The flow is out of the specified range.
There are two alarms in this instrument, #1 alarm
and #2 alarm. They can be configured in windows
M73, M74, M75 and M76.
For example, assume we need the Buzzer to start
beeping when the flow rate is less than 300 m3/h
and greater than 2000m3/h. The following setup
steps would be recommended.
1) Enter flow rate lower limit 300 in M73 for #1 alarm,
2) Enter flow rate upper limit 2000 in M74 for #1 alarm,
3) Select item ‘6. Alarm #1’ in M77.
3.18 HOW TO USE THE BUILT IN BUZZER
The built-in buzzer is user-configurable. It can be
used as an alarm. Use M77 for setups.
3.19 HOW TO USE THE OCT PULSE OUTPUT
The OCT output is on/off type. It is user-configurable.
For example, you can set the OCT output to be a
pulse signal for flow accumulation.
Use M77 for the setup.
Notice that the Frequency Output shares the same
OCT hardware.
The OCT output is wired to pin 6 (for positive) and
pin 5 (for ground) of the RS-232 connector. Refer to
section 6.1 for more details.
3.20 HOW TO SET THE BUILT IN CALENDAR
No modification on the built-in calendar will be needed
in most cases. The calendar consumes insignificant
amount of power. Modification will be needed only
when the battery is totally exhausted, or when the
replacement of the batteries takes a long time so that
the original clock data get lost.
Press the key in M61 for Modification. Use key
to skip over these digits that need no modification.
3.21 HOW TO ADJUST THE LCD CONTRAST
Use M70 to adjust the LCD contrast. The adjusted
results will be stored in the EEPROM so that the
MASTER ERASE (factory default restoration) will
make no effect on the contrast.
