REMOTE SWITCHING UNIT RCU-O2
The RCU-02 is a radio remote controlled switching unit that will allow the remote operation of any appropriate electrical
appliance that is required. The unit is constructed to commercial standards, giving the convenience of remote operation and in
most cases the reduction in installation costs will exceed the cost of switching unit.
The output of the unit is in the form of a relay change over contact rated at 8 amps 240V AC.
On the reception of a valid signal the output can be programmed to be momentary, toggled or timed using the internal dip
switches.
The remote control is achieved by using an encoded UHF radio signal produced by a key fob transmitter with a super-hetrodyne
receiver validating the transmitted code and activating the output accordingly.
The RCU-02 receiver requires a supply of 10 to 24V AC/DC and the output is via a pair of voltage free changeover relay
contacts.
INSTALLATION
First remove the lid and carefully retain the 4 lid screws.
The DIP switches should be positioned in line with the table (overleaf), in order to establish the correct output control (Latched,
momentary or timed).
The receiver unit must be securely mounted, using the mounting bracket provided, vertically with the active part of the aerial
(last 155mm) being positioned away from any metal shielding and extended as far as practically possible. Avoid positioning in
close proximity to electronic equipment as interference from such equipment in certain circumstances could reduce the
operational range.
The unit is not designed to be weatherproof and should be located in a suitable dry environment
The wiring must be passed through the sealing gland, and connected appropriately (see diagram). Ensure that the supply to the
unit is appropriately fused and if there is any doubt whatsoever regarding the electrical installation consult a competent
qualified electrician. The cables must be clamped securely by tightening the sealing gland using a 15mm spanner ensuring that
an adequate clamp is formed against the outer sleeving of the cables.
All connections to the unit must made via the screw blocks provided. Ensure that there are no loose strands of wire present and
that all connections are secure. If the load requires an earth, this MUST be provided.
Terminals 4 and 5 are electrically connected, therefore terminal 4 can be used to link the supply to the relay contacts if
required.
Refer to 'Wiring diagram ' for connection details.
Before applying power ensure that the installation is both complete and safe, and secure lid with the four screws provided.
After the power is applied allow approximately 5 seconds for the electronics to stabilise. Activation of the remote transmitter will
activate the receiver output, provided that it is within range.
