Digitally adjustable motor dimmer. Standby loss 0.3 watt only. Minimal speed, maximum speed and dimming speed are adjustable. Modular device for DIN EN 60715 TH35 rail mounting. 1 module = 18mm wide, 58mm deep. Motor dimmer with phase control for L loads up to 300W, depending on ventilation conditions. Only 1 fan motor should be connected. Universal control voltage 8 to 230V UC and additionally the universal voltage control inputs 8 to 230V UC central ON and central OFF. The control inputs are electrically isolated from the 230V supply voltage and switching voltage. Switching in zero crossing and switch-on at increased speed. If there is a power failure, the switch position and the speed level are saved. The device can be switched on when the power supply is restored. Automatic electronic overload protection and over-temperature switch-off. Enter the 6 functions and times using the MODE and SET keys as described in the operator manual. The functions and times are indicated in the LC display. Other features include language selection and keylock. The total switch-on time is added and indicated in the bottom line of the display. It can be reset to zero. The top line shows the parameters during the setting procedure and the active function in service. The left arrow indicates the switch position ‘ON’ and the right arrow shows the keylock function when applied. During the setting procedure, the middle line shows the parameters set. In service, the middle line indicates the speed between 10 and 99 for the MOD and DSD functions or the remaining time in minutes for the Udo and ODT functions. MOD = Motor dimmer with settings for dimming speed DSP, minimum speed MI%, maximum speed MA%, memory function MEM+ and selection of the central control inputs ON and/or OFF when activated or deactivated. Short commands switch on/off, permanent activation changes speed. An interruption in activation changes the dimming direction. DSD = Motor dimmer with activation with two direction buttons for dimming direction. Setting the dimming speed DSP, minimum speed MI%, maximum speed MA% and memory function MEM+. When activation takes place via +E1, a short command switches on. Permanent activation dims up to maximum speed. A double-click immediately dims to maximum speed. When activation takes place via +F1, a short command switches off. Permanent activation dims down to minimum speed. No central control function. Udo = Motor dimmer as for MOD function with manual on/off. In addition, a time delay time TIM can be set from 1 to 99 minutes. When the time delay expires, the device switches off. Central ON has priority over Central OFF. ODT = Motor dimmer with run-on switch function with adjustable speed SP%, response lag AV adjustable from 1 to 99 minutes and time delay RV adjustable from 1 to 99 minutes. When the control voltage is applied, the device switches on after the AV time expires. When the control voltage cuts off, the RV time begins. When the RV time expires, the device switches off. No central control function. ON = Permanent ON at maximum speed, OFF = Permanent OFF. Press MODE and SET briefly and simultaneously to activate the keylock. Then press SET to confirm the flashing LCK. Press MODE and SET simultaneously for 2 seconds to deactivate keylock. Then press SET to confirm the flashing UNL.bis 300Watt, abhängig von den Lüftungsverhältnissen. Es darf nur 1 Lüfter-Motor angeschlossen werden. Die Steuereingänge sind von der Versorgungs- und Schaltspannung galvanisch getrennt. Schaltung im Nulldurchgang und Einschalten mit erhöhter Drehzahl. Bei einem Stromausfall werden die Schaltstellung und die Drehzahlstufe gespeichert und wird gegebenenfalls bei Wiederkehr der Versorgungsspannung eingeschaltet. Automatische elektronische Ãœberlastsicherung und Ãœbertemperatur-Abschaltung. 6 Funktionen und Zeiten werden gemäß Bedienungsanleitung mit den Tasten MODE und SET eingegeben und auf dem LC-Display angezeigt. Eine Sprachen-Auswahl und eine Tastensperre sind möglich. Die Gesamt-Einschaltzeit wird addiert und im Display in der untersten Zeile angezeigt.
