Verify that the PV output is now 20 mA gt You can also use the MCT 202 Toolkit to make any adjustments to an STT850 SmartLine Temperature Transmitter Alternately certain adjustments are possible through an Experion Station or Universal Station if the STT850 is digitally integrated with either of these stations Page 40 STT850 Temperature Transmitter User s Manual Revision 2 4 4 Changing the Default Failsafe Direction For HART or DE the transmitters are shipped with a default failsafe direction of upscale This means that the Transmitter output will set the current output to upscale failsafe maximum output upon detection of a critical status You can change the direction from upscale failsafe to downscale failsafe minimum output by moving the top jumper located in the Electronics module 4 4 1 DE and Analog Differences Failsafe operation is somewhat different between DE and analog operation e Analog operation Upscale failsafe drives the Transmitter output to 21 8 mA Downscale failsafe drives the Transmitter output to 3 6 mA e DE operation Upscale failsafe causes the Transmitter to generate a infinity digital signal Downscale failsafe causes the Transmitter to generate a infinity digital signal The Transmitter electronics module interprets either signal as not a number and initiates its own configured failsafe action for the control system 4 4 2 Procedure to Establish Failsafe Operation The failsafe direc
