Working
1). Do all connection as shown in connection diagram and turn on the instrument.
2). Display will indicates process value according to 4-20mA input available and according
to decimal point.
3). The Range Corresponding to 4-20mA is selectable from keypad.
4). If high range is to select 9999 then at 20mA input the display will show 9999
& if low range is to select 0000 then at 4mA input the display will show 0000.
5).
6). In High Alarm (For Mode-1),Initially relay-1 will be off condition. When Process value
equals set point-1 relay-1 will turn on. When process value equal set 1- Hys 1 then
again relay-1 will be off.
7).
11). If the input is not connected Display will show OPEN.
12). When Input Exceeds the full scale Range (Approx above 20mA) then Display will show
(OVER).
13). When input is lower than 4mA (Signal Low Level Range: 0 To5mA) then Display will show
(LOW).
In Low Alarm (For Mode-1),Initially relay-1 will be on condition. When Process value
equals (Set-1 + Hys-1) relay-1 will turn off. When process value equal set point-1 then
again relay-1 will be on.
In Band Alarm (For Mode-1),Relay-1 will be on between Set point-1 & Set point-2 condition.
8). Out Band Alarm (For Mode-1),Relay-1 will be off between Set point-1 & Set point-2 condition.
9). Absolute Low Alarm (For Mode-1), Initially Relay-1 will be off. When first time process value
equals (Set-1 + Hys-1) then relay-1 will be on. Again process value below Set point-1 relay
remains on.
10). Absolute Out Band Alarm, Initially relay will be off. When first time process value is in between
Set point-1 & Set point-2 relay will be on. Now, Process value is below Set point-2 & Above
Set point-1 relay remains off.
