User manual HONEYWELL TST-R

[. . . ] TEMPERATURE SWITCHES/TRANSMITTERS INSTALLATION INSTRUCTIONS TST. . . and TST. . . -R GENERAL INFORMATION Honeywell FEMA's TST and TST. . . R series thermostats require adjustment (configuration and parameterization) in only two modes (the basic mode and the expert mode) and are suitable for the precision-adjustment and monitoring of medium temperatures in the fields of plant construction, fluidics, process technology, and pneumatics, as well as in the monitoring and control of furnaces, heating units, and process temperatures, as well as for applications in the field of frost protection. These thermostats provide sufficient accuracy (0. 5% of the final value) for measurement monitoring in many laboratory applications. Models with built-on sensors for a temperature range of -50. . . +200 °C and models with an external sensor for a temperature range of -50. . . +400 °C are available. [. . . ] · · The text "CODE" then means that a code has not yet been defined and that the user is free to define one. The text "LOCK" then means that a code has already been defined and, moreover, that the device has already been locked. Assuming that the text "CODE" has appeared, you must now press the RPB in order to confirm that you do indeed wish to define a code. "0000" will then appear in the display. The desired code must now be defined by sequentially rotating (to select) and pressing (to confirm) the RPB for each digit of the desired code (which must be a 4-digit number between 0001 and 9999). After the fourth digit of the desired code has been defined, the text "LOCK" will appear. You should then rotate the RPB CW one tick, whereupon the "EXIT" screen (Fig. After confirming this by pressing the RPB, the device will re-enter the basic mode, and the 1-minute grace period will immediately become effective (see also section "Time-Out Function" on page 7). If a non-zero code has been defined, the following will apply: · · If the 1-minute grace period is allowed to elapse, or if the device is turned OFF and then ON again, 9 MU1B-0248GE51 R0903 TST. . . AND TST. . . -R ELECTRONIC TEMPERATURE SWITCHES/TRANSMITTERS 3. Rotate the RPB CW until you come to a screen displaying either "CODE" (indicating that as yet no code [CODE = 0000] had been defined) or "LOCK" (indicating that a non-zero code has already been defined). You can now either input the same (old) code or define a new code. The very next screen to appear will display either "EXPN" or "EXPL" (see Table 5 for the code-dependent meaning of this text; the first line is the default shipping setting). Changing "EXPN" to "EXPL" locks the device for configuration. Changing "EXPL" to "EXPN" unlocks the device for configuration. 4. Fig. LCD display screen after power-up If the user does not manipulate the RPB for 30 seconds, and if "LED-" has been set (in the expert mode), the LCD display screen's backlighting will be shut off automatically (see Fig. If (in the expert mode) "LED+" has been set, the LCD display screen's backlighting will remain on permanently. Table 5. Code-dependent meaning of text at power-up parameterization configuration code text (basic mode) (expert mode) 0000 EXPN unlocked unlocked 0000 EXPL unlocked locked 0000 EXPN locked unlocked 0000 EXPL locked locked Lost/Forgotten Code In the event that you have lost or forgotten your code, you can also unlock the device by means of the master code obtained from Honeywell (when contacting Honeywell, please state your device's serial number). Fig. LCD display screen 30 s after last manipulation Sequence of Display Screens in Basic Mode When in the basic mode, rotating the RPB one tick CW at a time results in the presentation, in the following sequence (see Fig. 37), of all of the individual screens available in this mode. At any time, you may rotate the RPB CCW to go back to earlier screens in the reverse sequence. Display state: If the user does not manipulate the RPB for 60 seconds, regardless of the current screen, the LCD display screen will revert to the first screen displaying the temperature. The values displayed in the following examples are valid for devices of the PST. . . -R series, which was chosen because it embodies the full range of possible functions.
