UAP1090 Flow Transmitter And Totaliser
Basic Operation A flow transmitter is connected to P1 and is scaled to read in litres per minute (L/min). The output is also scaled to produce 10V when P1 reads 60 L/min. Every 100mS an equation runs to produce a litres counter in M4. If the ...
UAP1103 Pulse Rate Transmitter And Totaliser
Input P1 is programmed to measure frequency in hertz. The hertz measurement is retransmitted on the output as 0-50Hz = 4-20mA. The P1 input is also scanned by the equation every 5mS. The state of the input (high or low) is stored and compared ...
UAP0003 Sewer Discharge Pump Disable by Rainfall
This application programs a USC701 to disable a sewer discharge pump from operating during wet weather. Operating Description After the 1mm of rainfall the power supply to the pump is isolated for at least one hour after the cessation of rain. ...
UAP0013 Up Down Movement Counter
This application is used to detect 0.1Vdc changes in a 0-10Vdc signal. Two relays will transmit any positive or negative 0.1Vdc changes allowing an external counter to count overall movement. This movement will not be more than one 0.1Vdc change ...
UAP1052 Variable Period Triangle Generator
Introduction This worknig example demonstrates the use of the equation editor to simulate the function of individual program branches and features: Integer maths is used to calculate values for use in the equation at power up. This technique ...
