When the system is locked, the user can still browse
menu windows, but cannot make any modifications
on the windows.
The password locking / unlocking is done in window
M47. The system can be locked without a password
or with a password consisted of 1 to 4 digits.
For no-password locking / unlocking, just press
key in window M47.
3.14 HOW TO USE THE INBUILT DATA LOGGER
The built-in data logger has a space of 24K bytes of
memory, which will hold about 2000 lines of data.
Use M50 to turn on the logger and to select the items
that are going to be logged.
Use M51 to set up the starting time, time interval, and
the duration each logging lasts.
Use M52 to select the data storage direction. Data
can be stored in a logger buffer or directed to the RS-
232C interface without being stored into the logger
buffer.
Use M53 to view the data in the logger buffer.
User needs to go to window M52 to clear the logging
data remained in the RS-232C interface and in the
logger buffer.
3.15 HOW TO USE THE FREQUENCY OUTPUT
The flow meter will produce a pulse output with every
unit of liquid flow. This pulse could be used by an
external pulse counter to accumulate the flow rate.
Refer to
3.4 and 3.5
for the setup of the totalizer units
and multiplier.
The totalizer pulse output can only be connected to
OCT devices or BUZZER hardware devices.
For example, assume that the POS totalizer pulse
output is needed, and every pulse represents
0.1cubic meter of liquid flow. Assume also that the
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:
• Select the Cubic Meter (m3) unit in window M32.
• Select the Multiplier factor as ‘2. X0.1’ in window
M33.
• Select the output option ‘9. POS INT Pulse’ in
window M77. (INT stands for totalized )
3.16 HOW TO USE THE TOTALIZER PULSE OUTPUT
