Faulty 4-20mA Output
If sensor has a normal reading with no faults displayed, and the 4-20 mA signal output is 0mA….
Check that wiring is properly connected at terminal blocks and through to controller inputs.
The 4-20mA output loop must be closed (resistance of < 1000 ohms) to avoid the Loop Fault.
Perform a “Signal Output Check” sequence via Section 3.5.6 and verify 4-20mA output with current meter.
Swap with a known-good transmitter module to determine if the transmitter module’s 4-20mA output circuit is
faulty.
If the 4-20mA current loop is still out of tolerance, contact Detcon at Service@detcon.com
, or contact Detcon
customer service.
