• Note that, as in Fig. 3, the N/O (normally open) contacts are connected to the screen and projector lift's
MOMENTARY terminals. This allows the momentary action to occur.
• As a practical matter, it will be necessary to see that the projector and the screen positions are both UP
prior to the issuance of the first command. This will ensure that their actions will be synchronized so that
they will both travel in the correct direction when activated.
To overcome the possibility of incorrect synchronization, a method utilizing separate UP/DOWN
paired
commands is illustrated in Fig. 5.
• Fig. 5 assumes that the screen, projector lift, motorized drapes, etc., have inputs that will execute the
desired action with constant ON or
maintained
switch closures.
• The N/C (normally closed) terminals, in this case, are connected to the UP terminals on each of the
controllers, thus placing a maintained closure on them for the UP position.
• Similarly, the N/O (normally
open) terminals are con-
nected to the DOWN termi-
nals on each of the control-
lers. A maintained closure
on them, when activated,
will execute the DOWN po-
sition.
• For this type of operation,
you would program one
button on the Handheld
Learning Remote with the
Pair OFF command (UP)
from the RC68+ Program-
mer, and a 2nd button with
the Pair ON command
(DOWN). See Fig. 2.
In this way, positive UP/DOWN commands can be issued without any possibility of confusion.
Using the Voltage Controlled Input (CI) on the CC12
The CC12 Relay can be operated with a DC control voltage at the CI terminal, instead of IR, if desired. This
allows the switching of high current systems (up to 5 Amps) with a low current DC control signal.
• In Fig. 6, the STATUS (or CO output) of a ZPR68 (+12V) drives the CI (control input) of a CC12 when
the zone is turned ON & OFF. (The common CO of the ZPR68 could also be used).
• A 781RG powers the CC12 as well as supplying the needed +12V to activate the controlled device. If more
than 200 mA is required to operate the controlled device, then a higher current power supply must be used,
such as the 782-00 (12V, 1A).
