6 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 1.
• 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.
6.1 Operation with Hand-held Transmitter SHT-7 C
For the hand-held transmitter, T1 through T3 stand for the signals, which are generated with transmitter keys 1
through 3. The SHT-7 C, for example, delivers the signals T1 through T3.
6.2 Operation with Transmitters for Stationary Mounting TX-73 (B)
T1 through T3 react now on the rising edge of the (ON) signal from the transmitter.
When the contact is opened, a Reset-signal will be there for the duration of the transmission time set if
selected.
In every case, the user needs to follow the operating instructions for the transmitter being used.
