Double sided#

The double sided clock consists of two parts, one serving as the control module (this one encompasses the jacks to connect power voltage, synchronization source, the temperature sensor and the keyboard to the clock) and the other serving as the display module (with the terminal for the connection of the interconnecting cable). Both clock parts are interconnected via a 10‑core flat cable. The clock suspension part is delivered separately.

  1. Interlace the incoming conductors through the pipe which servers as the clock suspension. Secure the ceiling suspension (or wall bracket) to the ceiling (or the wall) using 4 wood screws of 5 mm diameter.

  2. The frame is fixed using two suspensions (above) and two sliding springs (bottom). Lift‑off both parts of the clock from the anchoring plate using a screwdriver inserted in between the sheet and the frame at the point where there are the sliding springs on the clock bottom side.

  3. Disconnect the interconnecting cables by decoupling the terminals on the control PCB.

  4. Interlace the incoming conductors through the pipe insert on the anchoring plate to the side which finds itself to the opposite of the terminal board. Slip‑on the plate onto the suspension in a way that the screws fit into the upper groove on the pipe insert. Fix the connection by tightening the screw using an Allen key.

  5. Interlace the incoming conductors through the opening located next to the terminal board and connect the conductors to the terminal board on the anchoring plate 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 onto the anchoring plate.

  6. Mount the connectors to the cable of temperature sensor, to the keyboard cable, Ethernet cable or to the RS-485 interface connector 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).

  7. Place the display part of the clock to the anchoring plate at a position which is opposite to the terminal board and suspend this part onto the upper springs. Interlace the 10‑core interconnecting cable through the lower opening which finds itself at the closest to the terminal board on the anchoring plate.

  8. Care should be taken when placing the cables between the frame edge and anchoring plate, so as not to nip them. Snap the clock onto the springs by pushing by pushing on the lower frame part.

  9. Connect the 10‑core interconnecting cable and the interconnecting cables into the corresponding plugs on the clock control PCB.

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

Warning

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

  1. Put the control part of the clock opposite to the anchoring plate and suspend it onto the upper springs. Care should be taken when placing the cables between the frame edge and the anchoring plate, so as not to nip them. Snap the clock in onto the springs by pushing on the lower part of the frame.

  2. Check whether the anchoring plate on the sides fits exactly into the grooves established in both parts of the calendar digital clock (these must be pushed against each other in a way to mask the anchoring plate – after placing the parts the plate shall not be seen).

  3. Remove the blind cap from the opening on the both lower sides of clock.

  4. Insert Allen key into the opening on the lower side of the clock. Turn the key softly in anticlockwise direction. The frame catch will snap in. Secure both parts of the clock.

  5. Replace the blind cap on the opening.

  6. Loosen the screws on the suspension using Allen key and lift the clock into the suspension in a way that the screws fit into the lower groove on the pipe insert. Secure the attachment by tightening the screw using the Allen key.

  7. Loosen the screws on the suspension using Allen key and lift the clock into the suspension in a way that the screws fit into the lower groove on the pipe insert. Secure the attachment by tightening the screw using the Allen key.

Note

During the disassembly first withdraw the clock and suspend the suspension on the upper groove at the pipe insert.
