3.16 How to use the Totalizer Pulse Output?
The totalizer output will produce a pulse output with every unit flow of the totalizer .
Refer 3.4 and 3.5 for the setups of the totalizer units and multiplier.
The totalizer pulse output can only be realized by mapping the pulse output to the OCT or BUZZER
hardware devices.
For example, assume that the POS totalizer pulse output is needed, and every pulse should represent 0.1
cubic meter of liquid flow; the pulse output will be mapped to the internal Buzzer, so that with every 0.1
cubic meter of flow the BUZZER will beep for a while.
The following setups should be taken/performed:
(1)
Select the unit Cubic Meter under window M32.
(2)
Select the Multiplier as ‘2. x0.1’ under window M33.
(3)
Select the output option ‘9. POS INT Pulse’ under 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.
Both for the BUZZER and OCT output the triggering sources of the event include the following:
(1)
Alarms on when there is no receiving signal
(2)
Alarms on when there is poor signal received.
(3)
Alarms on when the flow meter is not in normal measurement modes.
(4)
Alarms on reverse flow.
(5)
Alarms on the overflow of the Frequency Output.
(6)
Alarms on when the flow is out of a designated range set by the user.
There are two out-of-normal-range alarms in this instrument. They are called#1 Alarm and #2 Alarm. The
flow range can be user-configurable through M73, M74, M75 and M76.
For example, assume that the Buzzer should start beeping when the flow rate is less than 300m3/h and
greater than 2000m3/h, the following steps for setups would be recommended.
(1)
Enter 300 under M73 for #1 alarm low flow rate.
(2)
Enter 2000 under M74 for #1 alarm high flow rate.
(3)
Select the item reading like ‘6. Alarm #1’ under 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 output?
The OCT output is user-configurable, which can be performed by selecting the proper input source such as
pulse output. Use M78 for the setups.
Please make sure that the Frequency Output shares the OCT.
The OCT output shares pins with the RS-232C interface, and the terminal is at Pin
6
and the ground is at
Pin
5.
