INSTALLATION
First remove the lid and carefully retain the 4 lid screws.
The DIPswitches 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 holes provided, vertically with the aerial
pointing upwards. Avoid positioning in close proximity to electronic equipment as interference from such
equipment in certain circumstances could reduce the operational range.
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 19mm spanner ensuring that an adequate seal is formed against the
outer sleeving of the cables (IP65 weather proof).
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;
the comm. block can be used to connect the incoming earth to corresponding earth on the load.
Refer to ‘Wiring diagram’ for connection details.
Prior to attaching the lid, check the integrity of the sealing gasket, using all 4 screws provided; tighten
evenly until a weatherproof seal can be established.
Before applying power ensure that the installation is both complete and safe.
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.
CODING RADIO KEYS INTO UNIT
Normally the unit is supplied with 1 dual button radio key coded into the unit.
In this situation, when the unit is first powered the unit will enter Auto Coding (see below), after a key has
been added or ten seconds have elapsed the LED will illuminate green, indicating that power is applied to
the unit and h as been pre-programmed to respond to at least one radio key. If the LED is red this indicates
that the unit has no radio keys programmed.
The unit is capable of responding to 9 radio keys of differing codes
.
Programming
1. Press and release the function button (see diagram), the LED will extinguish for a brief period, followed
by a 10 second coding period. During this period the LED will flash green, the number of times the LED
flashes correspond to the number of radio keys that are coded into the unit. (If the LED does not flash then
no radio keys are programmed).
2. Press a button on the radio key that is required to be coded into the unit, the LED will flash yellow
briefly to confirm that the unit has accepted the radio key.
3. The LED will illuminate green to show that normal operation has resumed, and the unit will respond to
the newly coded key. If the unit does not respond to the key then this will probably due to the 10 seconds
allowed for coding having elapsed before the key fob button has been pressed (in this case go back to step
1) or the unit already has the maximum 9 radio keys programmed.
Auto Coding
In some applications it is inconvenient to access the coding button. In this instant it is possible to add radio
keys by followingthe procedure below:
1. Disconnect the power supply.
2. Re -connect the supply and immediately press the corresponding button on the radio key that you require
to be added within range of the receiver. The unit will learn and store the code from the radio key and
regard the code as valid.
NB. The unit will not ‘learn’ the radio key code if more than ten seconds have elapsed after applying
power before the radio key button is pressed or if the unit has the maximum number of keys already stored.
If the unit receives a code that is already programmed the unit will leave ‘Auto-coding’ and operate
normally.
It not possible to delete keys without access to the ‘coding button’
