7. Principle of Operation 9 3 2 System Response Time The analog output response time to reach steady state due to a change in the flow rate is approximately 1 8 of a second When flow stops the time for the analog output to return to 4 mA will be between 25 and 8 seconds depending on the Maximum Sample Time MST setting MST is adjusted using the NB DATA command where NB is a value between 1 and 80 The default MST setting is NB 1 Adjusting the MST is only recommended for low flow applications where the minimum input frequency is below 1 Hz HP 310 10 Principle of Operation This page intentionally left blank HP 310 Installation 11 4 Installation NOTE CATI flow input interfaces with magnetic type pickup coils and contact closure only If another type of coil is required refer to CAT 2 and CAT3 models 4 1 Typical Connections Loop powered with MAG Coil Installation DC POWER SUPPLY Mag Pickup Coil LOAD SISISISISISIOISISIO Dip Switch Settings PCA183 HP 310 12 Installation 4 2 Communications Connections CATI is equipped with RS232 serial communication port for changing CATI configuration diagnostics functions and flow monitoring Hoffer communication program DevConfig 3 0 must be used to communicate with CATI The RS232 serial port connector is located under the top plate of CAT1 and may be accessed by removing the two screws from the top p
