A Leader In Level Measurement Solutions 401-0400 Series Single Channel Receiver Verify™ loop diagnostics allow remote manual check and continuous selftesting. This Single Channel Receiver supplies a 4-20 mA loop to, and monitors the status of, a two-wire, on/off level control transmitter (RF, or, Ultrasonic Technology). It provides relay indication of loop status, showing loop in 1) normal, 2) alarm 3) fault condition 4) Verify test in progress. Choosing the Verify option provides a remotely activated test which completely and positively checks the spill prevention system, including the loop wiring, sensing element, and final control elements. Continuous Level Simulation Means Maximum Assurance Continuous automatic verification (high level duplication), along with manual magnetic key certification, testing the entire control loop (including final control elements) giving the ultimate in performance reliability. Two-Wire Continuous Loop Diagnostics Two-wire design allows for continuous selfchecking loop diagnostics, which check the twisted pair for open and short circuits. The system was designed for intrinsically safe outputs. Two-Wire Overall Installed Cost Savings Two-wire technology eliminates need for line power at the field transmitter and saves on costs for associated hardware. With the AutoVerify option, a test pulse occurs every ten seconds, signaling the Verify test at the transmitter and duplicating a high level condition at the sensing element. The receiver then checks that the switch has responded properly. If the switch does not respond to the test, the receiver indicates a fault condition in the output loop. The receiver provides DPDT relay output for fault indication. (NOTE: When using the Single Channel Receiver with the Two Wire IntelliPoint product, specify receiver without Verify. Verify is an onboard feature of the IntelliPoint.) The Most Complete System Testing Package Available. To test the entire control loop, and any final control elements, a Certify™ test may be activated manually at the receiver. This manual test not only tests the entire spill prevention system, but also checks that the AutoVerify selfcheck circuitry is functioning.
