AI5 value range.
Used to enter temperature/pressure values that are corresponding to 4mA and 20mA
input current.
Windows to setup the frequency range (lower and upper limit) for the frequency output
function. Valid range is 0Hz-9999Hz. Factory default value is 0-1000 Hz.
For Version-12, Version-13, Version-14 flow meters, you need a hardware module,
which shall be plugged to the Serial Expanding Bus, for the frequency output function.
Please remember to order the module if you need frequency output function.
For Version-15 flow meter, you need to indicate on your orders that you need the
frequency function; Otherwise you will get a flow meter which has no frequency output
circuits.
Window to setup the minimum flow rate value which corresponds to the lower
frequency limit of the frequency output.
Windows to setup the maximum flow Rate value that corresponds to the upper frequency
limit of the frequency output.
LCD display backlight control. The entered value indicates how many seconds the
backlight will be on with every key pressing. If the enter value is great than 50000
seconds, It means that the backlight will always keeping on.
LCD contrast control. The LCD will become darker or brighter when a value is entered.
Working timer. It can be cleared by pressing ENT key, and then select YES.
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’
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.
Window to setup the lower limit of flow rate for Alarm#2.
Window to setup the upper limit of flow rate for Alarm#2.
