Page 4: Field Of Application
IEC 61508. The operating limits are defined in the data sheets and operating instructions for the separate models. In case of questions, please contact your ABB partner. Acronyms and abbreviations Acronym /... - Page 5 In multidrop mode, up to 15 field devices are connected in parallel to a single wire pair. The analog current signal simply serves to supply power to the devices in two-wire technology with a fixed current of ≤ 4 mA. SM/TTX200/TTX300/SIL-EN TTH200, TTR200, TTH300, TTF300, TTF350...
- Page 6 In this configuration the two current signals 4 … 20 mA have to be evaluated accordingly by the downstream logics unit (a DCS, for example). This results in an HFT = 1 (1oo2 architecture) for corresponding SIL3. TTH200, TTR200, TTH300, TTF300, TTF350 SM/TTX200/TTX300/SIL-EN...

Page 8: Terms And Definitions
A specified function that is carried out by a safety-related system functions with the goal, under consideration of a defined dangerous incident, of achieving or maintaining a safe state for the system. Example: limit temperature monitoring. TTH200, TTR200, TTH300, TTF300, TTF350 SM/TTX200/TTX300/SIL-EN... -
Page 9: Safety Function
Safety function Safety function TTH200-.H, TTR200-.H, TTH300-.H, TTF300-.H, and TTF350-.H transmitters generate a linear temperature unit signal of 4 ... 20 mA. All safety functions refer strictly to the analog output signal. The entire valid range for the output signal must be configured between min. 3.8 mA and max. -

Page 13: Configuration
To implement this, proceed as follows: Activating / Deactivating write protection 1. TTH300-.H, TTF300-.H, and TTF350-.H via the LCD display with local keyboard Go to "Device Setup", "Write Protection" and enter a password other than "0110" to activate write protection. Enter the password "0110" to disable write protection (see the operating instructions). - Page 14 Checks: Write protection must be checked as follows: 1. TTH300-.H, TTF300-.H, and TTF350-.H locking via the LCD display with local keyboard Check whether the lock icon is displayed on the LCD display. Select the "Fault Signaling" menu and make sure the edit icon is not showing on the LCD display.
- Page 15 • Drift duration Maximum 120 s Sensor type freestyle characteristic and Callendar-Van Dusen on the TTH300-.H, TTF300-.H, and TTF350-.H When using these two configurations, it is necessary to check at least 3 reference points to verify the configured characteristic. For complex curves, check more reference points according to complexity.
