SH2D10V424 Carlo Gavazzi

SH2D10V424, Analog Output Dimmer Model SH2D10V424., SH2D10V424, This universal dimmer from 1 to 10 V is designed for DIN rail mounting and has a width of 2 DIN modules. It is equipped with 4 independent outputs that, according to the defined percentage of regulation, offer a corresponding output from 1 to 10 V. It is suitable for the regulation of adjustable ballasts with analog inputs from 1 to 10 V. In order to ensure the switching function of the electronic ballast, the SH2D10V424 must be coupled with one or more relay output modules., SH2D10V424, If the SH2D10V424 is connected to the Dupline bus® and the bus is working properly, the dimmer will be in STANDARD mode and the green LED will be activated. The dimmer accesses the LOCAL mode if the button is pressed or if there is a bus failure or is not connected. In LOCAL mode, the dimmer does not support any bus command and the LED will flash. The dimmer can return to STANDARD mode only when the bus status is correct and one of the following events occurs: 1) Immediately after the return of the Dupline bus® 2) After a time limit of 1 minute after pressing a button 3) After restarting the power Button The pushbutton can be used with short or long presses (>2 seconds). Short press: All four outputs are on/off (switching function) with the setting value. The factory setting is 100%; in this way, the first time the button is pressed with a short press, the light turns on 100%. If the module memorizes another lighting scene, the light will turn on at that level. Long press: once the light is on, if the button is pressed for more than 2 seconds, the light will increase to 100% and reduced to 5%. This will be repeated until the button is held down. Each time the push button is pressed, the ramp will be reversed. With a short or long press of the button, all 4 outputs are activated at the same time. Push button activation overwrites the safe state. SH2D10V424 and relay output module Once a regulation function is configured, if a SH2D10V424 is used, it is also necessary to select the relay output modules: they can be decentralized or modules for frame. - SH2RE16A4 - SH2RE16A2E230 - BDA-RE13A-U Programmable parameters Output voltage In order to adjust the optimal output curve for the activation of LEDs or adjustable ballasts from 1 to 10 V, the user can define 6 thresholds for the output voltage. Threshold 1. It is the desired output voltage at a light intensity of 0%. Threshold 2. It is the desired output voltage at a light intensity of 5%. Threshold 3. It is the desired output voltage at a light intensity of 30%. Threshold 4. It is the desired output voltage at a light intensity of 50%. Threshold 5. It is the desired output voltage at a light intensity of 70%. Threshold 6. It is the desired output voltage at a light intensity of 90%. The programming of these 6 values is done through the SH software tool. An example of the use of this threshold is that of converters from 1 to 10 V that have an energy saving system according to which they are turned off if the input voltage is less than a predefined value (usually between 1.2 and 2 V approximately). In this case, threshold 1 (@0%) must be adjusted as a minimum value. See figure. Output curves: Ballast 1 is an example of an output curve for a ballast, while LED 1 is an example of an output curve for an LED of 1 to 10 V (see below). Soft on/off Soft on and off times are programmable from 0 to 30 seconds via the SH configuration tool. The default value is 2. Ramp time Ramp time is programmable from 0 to 30 seconds through the SH configuration tool. The default value is 2. Safe status in case of failure The output status of the dimmers, if there is a failure of the Dupline bus® or not connected, is programmed through the SH tool and the user can choose between the following options: 1. Output always disabled 2. Always on output 3. The output maintains the state it had before the disconnection. By default, the factory setting is disabled.
