The product should only be used in a case adequate for mains-voltage if applied!
The Relay Board is a state-of-the-art product. However, there is a risk of danger if installation or operation is performed by
unqualified personnel
If the relay contacts switch mains power supply, the electronics has to be operated in a corresponding installation casing.
Attention. Extreme danger!
When opening the product, live components may be touched. Isolate SHR-12 K1 from the mains power supply before
opening. Ensure that all connected devices and components are also disconnected from the mains-power supply.

System operating range
The system SH-7 is designed for a large operating range of many hundred meters. Walls including steel reinforced concrete can be
penetrated. The maximum range can be achieved under optimum conditions and by line-of-sight contact between transmitter and
receiver without disruption by external high frequency disturbances.
The following are possible causes that could reduce range of operation:
Obstructing buildings, vegetation or other factors will substantially reduce the operating range.
The distance between the antenna and the operator's body or other conducting objects (e.g. Earth) may influence the working
range.
Background "electrical noise" could be relatively high so that the signal-to-noise-ratio may decease and therewith the operating
range. Also other devices, with similar operating frequency, operated in the neighbourhood of the receiver may reduce the
sensitivity.
Operating the receiver adjacent to badly shielded electronic components (e.g. PC's) that can produce electromagnetic distortion,
may severely reduce the range of operation and could result in intermittent operation.
Adjustable and open components should not be adjusted or modified.

Description
The SHR-7 K1 provides the choice of a key-function or a timer switching function (up to 60 minutes) as well as a steady switching
function.
A channel with key-function can be set with the shortest timer setting (refer to table 1). The relay remains closed as long as the
transmitter key stays activated.
For applications, where, for example, inductances produce signal glitches due to electromagnetic interference during the switching
process (apparent relay bouncing), the timer setting can be increased in small steps. The resulting delays, which can be considered
as falling edge delays, avoid the undesirable bouncing of the relay contacts when short glitches occur.
Furthermore, the adjustable timer settings provide time-limited switching (falling edge delayed) of any number of devices.
For applications that require a steady on/off switching, the user can select the static function (one button switches on and a second
button switches off)
Independently of the selected function, the relay can be controlled also by a wired connection, e.g. via an external push-button (not
included in delivery).

Installation
Open the housing by turning the 4 screws in the bottom left hand side.
Because the circuit board is open, make sure that no static discharges occur and that the components will not be damaged!
Open cable entries using a suitable piercing tool. To avoid damage to electronics, only entries on the screw-terminal side should be
used.
Coding: The eight small dipswitches "CODE" below the receiver module allow 3 switch positions (+ / - / 0), which
have been set to the center position at the factory.
To avoid undesirable triggering by other senders, the user should choose an individual code by changing one or
more dipswitch positions before using the device.
The code set at the SHR-X K4 must coincide with the code of the sender being used (same switch positions)!
Connect all connection cables for the power supply at the corresponding screw terminals. Please note that the voltage applied at
screw-terminals 1 and 2 can be only between 12 and 24 V. You can apply DC or AC voltages, which means, you can ignore the
polarity in case of DC voltage.
The maximum cross section of wires to be used is limited to 1.5 mm²
The connection wires are to be stripped to a maximum of 4 mm (to avoid accidental contact)
Connect the wires to devices into screw-terminals for change-over-contacts NC/CC/NO as per fig.
All wiring should be installed neatly and rectilinearly. Powered wiring must not be mounted over the electronic board. Care must be
taken that wiring is not squeezed or damaged.
Select the desired function of your receiver using „ON/OFF" jumpers :
The jumper in the uppermost position "ON" effects that the relay can be switched on with the transmitter key 1; 2 or 3.
The jumper in the lower position "OFF" effects that the relay can be switched off with the transmitter key 1; 2 or 3.
