Double sided#

The double sided clock consist of three parts, one front panel serving as the control module (this one encompasses the jacks to connect powering voltage, synchronization source, the temperature sensor and the keyboard to the clock), and the rear panel serving as the display module (with the terminal for the connection of the interconnecting cable). This part is stainless steel clock body with connecting terminal block. Both panel are interconnected via a 10‑core flat cable. Front panel of the clock is held by neodymium magnets. Rear panel is fixed by the screws and it is not necessary to dismount it. The clock suspension part is delivered separately.

  1. Pull the incoming conductors through the pipe which serves as the clock suspension. Fix the ceiling suspension to the ceiling using 4 appropriate screws of 5 mm diameter. Use dowels if necessary.

  2. Remove the front panel from the clock body. The panel is held by magnets, relatively high force required to remove it.

  3. Disconnect the interconnecting cables by decoupling the terminals on the control PCB. Disconnect the earth wire connecting the body to the front panel.

  4. Pull the incoming conductors through the pipe insert in the clock body. Slip‑on the clock body onto the suspension in a way that the screws fit into the lower groove on the pipe insert. Fix the connection by tightening the screw using an Allen key.

  5. On mains powered clock loosen the screw on the underside of the 230 VAC terminal cover and remove the cover.

  6. Connect the conductors to the terminal block on the clock body in accordance with the descriptive nameplate. Give an appropriate shape to the conductors or cut them off at a length which does not obstruct the mounting of the clock into the clock body.

  7. Mount the connectors to the cable of the temperature sensor, to the keyboard cable, Ethernet cable or to the RS-485 interface connectors if these are used.

    Attention

    If the clock is synchronized by LGC variant, please navigate to Clock Operation Non-Network Clock Operation to get detailed info about connection of various synchronization sources and receivers.

    For LGC variant, check and configure the position of DIP switch according to used synchronization signal (applies only for DCF, MOBALine, polarized impulse line or IRIG‑B).

  8. Push the temperature sensor connector, the keyboard connector, Ethernet connector or the RS-485 jacks into the corresponding terminals on the control PCB of the MASTER display.

Warning

Be careful not to swap terminals. Check the markings of the jack‑plugs.

  1. Connect the interconnecting cables into the corresponding terminals on the clock control PCB including 10‑core flat cable. Reconnect the earth wire to connect the clock body to the front panel.

  2. Put the MASTER display front panel to the clock body. Care should be taken when placing the cables between the clock body edge and the back side of the control front panel so as not to nip them.
