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, M76.
For example, assume that the Buzzer should start beeping when the flow rate is less than 300m 3 /h and greater than 2000m 3 /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.
