HONEYWELL STT700 Proof test The objective of proof testing is to detect failures within the HONEYWELL STT700 that are not detected by the automatic diagnostics of the transmitter. Of main concern are undetected failures that prevent the safety instrumented function from performing its intended function. -
Page 12: Calibration Procedure
Calibration procedure The transmitter should be taken out of service. The source for the input Temperature must be very precise, and certified for correct operation. Step Action Connect the HART host and establish the communications. Go to Online > Device Setup > Advanced Configuration > Calibration > Calibration Methods menu. Go to “D/A trim”... -
Page 13: Remote Parameter Configuration Verification
Remote Parameter Configuration Verification When configuring the HONEYWELL STT700 through a remote host, it is recommended that parameters that affect the 4-20ma analog output be verified using an alternate utility, before using the transmitter in a SIS. This helps to ensure that the parameters that are entered remotely by the host are not inadvertently changed from the user intended values. -
Page 14: Repair And Replacement
Repair and replacement Any failures that are detected and that compromise functional safety should be reported to the Global Technical Support Center (GTS). When replacing the HONEYWELL STT700 the procedures in the installation manual should be followed. Firmware update The user will not be required to perform any firmware updates. If the user has selected the firmware upgrade option, it can be done by Honeywell service representative. -
