SITRANS LC 500 PC laptop with Simatic PDM or HART communicator Diagnostics The internal diagnostic functions continuously monitor the operation of the transmitter An error signal is generated if a failure or irregularity occurs The SITRANS LC 500 sends the signal current according to the NAMUR NE 43 recommendation During normal operation the current remains within the range from 3 8 to 20 5 mA If the process exceeds its normal limits but is not in a fault or failure situation the signal current will be outside the measurement range 4 to 20 mA but will be limited to either 3 8 or 20 5 mA If a fault or a failure is detected the signal current is set to either 3 6 mA or 22 mA depending on the settings you have chosen This feature may be disabled by the user Depending on the system design the power supply may be separate from the PLC or it may be part of the PLC A 250 Ohm resistor is required only when the PLC is connected to a HART modem or a HART communicator The HART communicator and a PCL laptop computer cannot both be connected to the 4 20 mA loop simultaneously Page 32 SITRANS LC 500 INSTRUCTION MANUAL 7ML19985GE01 Current values used as signals from digital transmitters Current values for signal detection gt T bi Measurement value a Fault mA Value Fault mA Value n F 1 F 0 1 9 0 3
