Frequently Asked Questions

  • How do you read an existing configuration?

    This is a completely different procedure depending on the type of controller.

    • For the CTD controllers this goes as follows:

    In the SMIII via "File" or "Utilities / Setup / SD card", click on "Recover QDB from SD".

    After confirmation you choose the name and location where the file should be saved. The zipped QDB file is then read from the SD card of the CTD and saved. With a positive answer to the question "Unzip and open restored QDB?", All data will then be immediately available. If the data you were still working on was not sent or saved, you will first receive a notification to do so.

     

    • For a CTL controller follow the following procedure:

    Because this controller does not yet have a large memory, only limited data can be recovered. Ao the names are abbreviated to 12 characters and serial numbers are not stored anywhere.

    The first step is therefore to type in ALL serial numbers via SMII via "File / Modules". These 6-digit serial numbers can be found on every module (DIN rail, switch, detector, etc.). For the SWC0x switches, an extra option was provided to have them send their serial number via “Search for modules”.

    When you then click on the "down arrow", you can read all this limited information.

  • Always use the latest software for configuration.

    It is always recommended to use the most recent version. This version supports the newest modules and resolves all known bugs.

    If, for example, you enter a serial number and the correct module information does not appear, you are likely not working with the most recent software.

    A newer version will always be able to open the older files (.QDB) without data loss.

    The latest version of the System Manager software, along with the user manual and version history, can be found in the knowledge center.

General

  • Safety Regulations

    Read the full manual before installing the module and activating the system.

    WARNING

    • The device must be assembled and commissioned by a qualified electrician in accordance with country-specific regulations.
    • The device must not be opened except as described for battery replacement. The warranty is void if the module is opened.
    • Keep batteries out of reach of children.

Installation and wiring

  • Installation

    wall outlets or built-in enclosures

  • Check battery

    The battery voltage is checked by the module each time:

    • The status of the contact changes (sending the new status)
    • At least once every 24 hours after an operation.

    As soon as the battery status is considered weak, a "Battery Low" signal is sent at least once every 4 hours.

    Once the battery is empty, the red LED will blink 3 times shortly at an interval of 20 seconds and the low voltage telegram will be sent automatically. It is advisable to replace the battery at this point. (see "Replacing the Battery")

    If the voltage drops further, the module will shut itself off and no more status changes will be sent. 

  • Replace the battery
    1. Open the enclosure.
    2. Remove the battery from the holder and replace it with the new battery. Use only CR2032 type batteries. Ensure that the positive terminal is visible on the top!
    3. Click the enclosure shut again.
    4. If you have disconnected the wiring, check the connection again.

    Note: The module's link with the QWI/EW remains intact, no further steps are required.

  • Troubleshooting

    If the receiver does not respond to this module:

    • Check the battery status.
    • Verify that the wireless connection in the installation is not being disrupted between this module and the QWI/EW.
    • Check the configuration of the QWI/EW and whether the link with this module is still active.
    • Ensure that other wireless devices operating at the same frequency or in close proximity are not interfering with the operation of this product.

For each wireless module it is important that it is enrolled to the gateway (QWI/EW)
An I/O module receives a code from the QWI/EW, an input module sends its code to the QWI/EW.

When you briefly press a push button, it will send its transmission code and store it in a free place in the QWI. The transmission code is displayed and the key pressed is displayed in green.

However, with this module you can select whether you connect 4 push buttons or 2 long-term contacts. This requires a different wiring. A long-term contact can act as “normally open” (The I/O follows the status of the input) or “switch” (the I/O reverses with every change on the input)
