User manual CARLO GAVAZZI UDM 35 PROGRAMMING

[. . . ] After approximately 20 seconds, the unit will revert to RUN mode if no further entry is made. Movement across the flow chart (see product carton instruction sheet for BD35 and BD40) to a specific parameter heading is accomplished using the and arrow keys. The display will indicate the current setting for the first sub-parameter in this group. Each successive will scroll through the or keys when a remaining sub-parameters. [. . . ] In this example, we can divide the curve into 9 segments (9 segments + 1) corresponding to the vertical axis. The menu must be activated and the number of linearization points set (10 in this example). Then the input/output coordinates must be determined and entered into the program. In this example, going from right to left on drawing, Input 1 (shown on drawing as "1. 0"; displayed as "in. 01") = 4. Likewise "in. 02" (shown on drawing as 0. 9) =4. 5, ou. 02=0. 9. . . . . . Fast-forward to "in. 09"=12, ou. 09=0. 2, and "in. 10"=20, "ou. 10=0. 1. It is important to note that the first and last linearization points must correspond to those points defined in the scale menu . In this example: "in. 01"= LoE, "ou. 01"=Lo. d, "in. 10"=HiE, "ou. 10"=Hi. d. Inputs are noted on the "X" axis and the analog current values along the "Y" axis. The second input, 0. 9, has a value of 4. 5, etc. 10 UDM 35/40 PANEL METER USER MANUAL Navigating & Programming within the Linearization Menu As appears, press followed by and keys to choose to ignore or enable linearization . If you chose YES, you will be prompted to enter the number of Linearization Points, using the escape button to select the position, and the up /down buttons to select to confirm and advance. Press enter Next, the correlation between the inputs and outputs must be defined in the program. Press to toggle through the positions, and use the and keys to select the value. Repeat this procedure for each set of Inputs and Outputs, up through a maximum of 16. Press to advance to the next program step enter key sequence. Alarm Set-point Programming Up to 4 alarm set-points may be configured. You may configure each set point using the following parameters, in order, as shown below: Minimum set-point limit Maximum set-point limit Set-point setting 11 UDM 35/40 PANEL METER USER MANUAL Hysteresis selection Off-Delay Value (0-255s) On-Delay Value (0-255s) Relay Selection (normally energized or de-energized) Alarm Type (off, down, up, up with latch, down with latch) Color of display during alarm (red, orange, green, none) If "none" is selected, basic display color remains. 12 UDM 35/40 PANEL METER USER MANUAL Navigating through this program sequence Minimum Set-Point The lowest value, below which, it is not possible to program a set-point. When sequence. Press is first displayed, you have reached the Set-point program to enter program. To skip this step and advance to the next parameter, press the enter key . Otherwise, press the escape key to select the proper numerical position to enter a value. Press the up/down arrow to select the numerical value for each position. When completed, keys press enter to confirm and advance to next programming sequence. Maximum Set-Point The highest value, above which, it is not possible to program a set-point. Maximum Set-Point Limit . Using the same procedure as above, press the escape key to toggle to the appropriate position. Press up/down arrows to confirm your choice and advance to the next programming step. Set-Point The actual value that must be reached to trigger an output. When is displayed, press the key to toggle to the desired numerical position. to confirm and advance to the next parameter in the program Press sequence. 13 UDM 35/40 PANEL METER USER MANUAL Hysteresis The point at which an active alarm output must revert to for the alarm output to turn off. [. . . ] Any confusion and concern that has surfaced has surrounded the issue of setup with the PC/laptop. The following segment is meant to clarify how to establish solid communication between UDM and PC. Do not connect or disconnect either end of the UCABLE when the input signal is connected to the input module. This may result in failure of the input module, the BD35/40 display, and possibly the PC.
