  • Page 3: Description

    Description PX714 is an intelligent transistor dimmer with phase cutting where control is carried out on the falling edge (the so-called trailing edge dimming). The module controls four channels 200W each and has an built-in system of interference suppression, fuses and signal controls. The device has the DMX512 input, analogue inputs 0 –...

  • Page 4: Safety Conditions

    The device is closed in the standard housing designated for bar assembling. Safety conditions Dimmer PX741 is powered directly from standard 230V grid, what can cause electric shock when safety rules are not observed. Therefore it is necessary to observe the following: 1.
  • Page 5 5. To connect the devices to the dimmer, use only wires with a cross- section of not less than 0.75mm. 6. Dimmer can be installed in closed electrical switching stations only, with restricted access for people who does not handle proper qualifications 230V supplied devices maintenance.

  • Page 6: Connectors And Control Elements

    NOTE!!! 1. The inappropriate connection of a protective wire creates the risk of electric shock. 2. The inappropriate connection of the neutral wire results in the faulty operation of a dimmer. 3. The dimmer can regulate exclusively the circuits (of capacity) of the resistive type or the capacitive one.

Calibration should be carried out to ensure that the inputs work correctly. In order to do it, the maximum value should be set in the input and the CAL option should be selected, and then the message YES should be confirmed with the key “enter”.

    Each next short pressing of a key when the function realizes the parameter hLd causes that the time of the parameter is counted from 0 (it reset the time elapsed), prolonging the operation of the function at the same time. The value of this parameter is only taken into consideration in the fourth function.

    RDM – available parameters The PX741 supports the DMX-RDM protocol. DMX protocol allows only of a one-way data transmission, while its extension the RDM protocol can transmit information in two directions. This makes possibility of monitoring activities of the compatible devices. Thanks to RDM some available settings of compatible devices may be programmed using this protocol.
