2.1Single-sided clock
The frame is fixed using two suspensions (at the above) and two sliding springs (at
the bottom). Lift-off the anchoring plate using a screwdriver inserted in between the
sheet and the frame at the sliding spring point on the clock bottom side (chapter
2.3).
Disconnect the interconnecting cables by decoupling the terminals on the control
PCB.
Drill three anchoring holes into the wall, of a diameter adequate to accommodate
wood-type screws of 4 to 5 mm diameter. As a template for marking the position of
the holes the anchoring plate can be used.
Interlace the incoming conductors through the opening in the anchoring plate and fix
the sheet to the wall.
Connect the incoming conductors in accordance with the descriptive sheet on the
terminal board, placed on the anchoring plate (chapter 2.5). Give the conductors an
appropriate shape or cut them off to a length that will not obstruct the placement of
the clock onto the anchoring plate.
Mount the connectors to the cable of the temperature sensor, to the keyboard cable,
Ethernet or to the RS 232 and RS 485 interface cables, if these have been
delivered.
Push the temperature sensor connector, the keyboard connector, Ethernet
connector or the RS 232 and RS 485 jacks into the corresponding terminals on the
control PCB (chapter 2.6 and 2.9). Check the marking of the jack-plugs, in order to
prevent their mix-up.
Connect the interconnecting cables into the corresponding terminals on the clock
control PCB.
Put 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.
Check whether the anchoring plate on the sides fits exactly into the groove in the
clock frame.
Remove the blind cap from the opening on the clock bottom side.
Insert Allen key into the opening on the bottom side of the clock. Turn the key softly
in anticlockwise direction. The frame catch will snap in.
Replace the blind cap on the opening.
To loosen the frame catch, use the reverse procedure (turn clockwise).
2.2Double-sided clock
The double-sided clock consists of two parts, one 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 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.
Interlace the incoming conductors through the pipe which serves as the clock
suspension. Secure the ceiling suspension (or the side console) to the ceiling (or the
wall), using 4 wood screws of 5 mm diameter.
The frame is fixed using two suspensions (at the above) and two sliding springs (at
the 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 (chapter 2.3).
Disconnect the interconnecting cables by decoupling the terminals on the control
PCB.
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.
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 (chapter 2.5). 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.
Mount the connectors to the cable of the temperature sensor, to the keyboard cable,
Ethernet cable or the RS 232 and RS 485 interface connectors, if these have been
delivered.
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.
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 onto the springs by pushing
on the lower frame part.
Push the temperature sensor connector, the keyboard connector, Ethernet
connector or the RS 232 and RS 485 jacks into the corresponding terminals on the
control PCB (chapter 2.6). Check the marking of the jack-plugs, in order to prevent
their mix-up.
Connect the 10-core interconnecting cable and the interconnecting cables into the
corresponding plugs on the clock control PCB.
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.
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 anchorage plate (after placing the parts the plate
shall not be seen).
Remove the blind cap from the opening on the both lower sides of clock.
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.
Replace the blind cap on the opening.
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.
To loosen the frame catch use the reverse procedure (turn clockwise).
Note: during the disassembly first withdraw the clock, and suspend the suspension
