User manual HONEYWELL PST

[. . . ] ELECTRONIC PRESSURE SWITCHES/TRANSMITTERS INSTALLATION INSTRUCTIONS PST. . . and PST. . . -R GENERAL INFORMATION Honeywell FEMA's PST. . . and PST. . . -R series Electronic Pressure Switches and Transmitters are microprocessorcontrolled pressure measurement devices suitable for an extremely wide range of applications, including the precision-adjustment and monitoring of system pressures as well as the monitoring and control of pumps and compressors. All versions feature an integrated LCD display, two LED indicator lights presenting the switching and alarm status, and an integrated rotary/push button for parameterizing and configuring the device according to user needs. [. . . ] Unlocking a Locked Device A device locked for parameterization and configuration can be unlocked by inputting the correct code. This is done by going through the basic mode's sequence of screens (Fig. 35) and stopping at the last screen, in which the text "CODE" (instead of "EXP") will appear, thus prompting the user to input the correct code. You must now press the RPB in order to confirm that you wish to input the code. "-- -- -- --" will appear in the display. The correct code must now be inputted by sequentially rotating (as appropriate) and pressing the RPB for each digit of the code (which must be a 4-digit number between 0001 and 9999). If you have inputted the incorrect code, the device will remain in the basic mode and display the text "CODE". Inputting the correct code will place the device into the expert mode. The 1-minute grace period will then immediately become effective again. The user then has the option of either remaining in the expert mode (where configurations can be viewed and changed) or of entering the basic mode. Defining No Code (CODE = 0000) Defining (and permanently storing) a code of 0000 (which is the default shipping setting) means that that the device will under no circumstances ever become locked. If, while in the expert mode, any parameters / configurations are then changed but not permanently stored (via SAVE), the device will nevertheless remain in the expert mode until either a SAVE or a REST (for "restore") is performed. Locking the Device for Configuration ("EXPN" -> "EXPL") It is possible to lock the device for configuration; thereafter, it is still possible to enter the expert mode, but it is impossible to make any changes while there. To do this, it is necessary to change the default shipping setting of "EXPN" to "EXPL". This can be done during the power-up sequence as follows: 1. Immediately after the power is turned ON, press and hold down (for approx. 5 seconds) the RPB until the software version is displayed. Now rotate the RPB CW and go through the sequence of screens until you reach a screen displaying either "EXP" (indicating that as yet no code [CODE = 0000] had been defined) or "CODE" (indicating that a non-zero code has already been defined). If "EXP" appears, you can enter the expert mode and press the RPB to proceed immediately to step 3. If "CODE" appears, you must first input the correct code in order to enter the expert mode, press the RPB, and then proceed to the step 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. [. . . ] AST1 wall attachment set 19 MU1B-0188GE51 R0803 PST. . .
