3 Preparat on
For universal use, the product could be operated with the 433MHz receiver-module SHR-7. Start installing the selected Receiver-
module for 433 MHz, connecting the receiver carefully to the socket on the board (ref. Fig. 1: Circuit Board SHR-X L3). Make sure the
Receiver is fixed and all Pins are connected well.
If necessary, install an ext. Antenna according the recommendations given in the Operating manual of the receiver.
Mount the product in a case adequate for 230V~/50Hz mains-voltage. Space must be enough to place all cables correctly and free
from the electronic parts inside. Powered wiring must not be mounted over the electronic board.
Ensure that the antenna is mounted as far as possible away from power wiring and is not in contact with any powered part
particularly in the terminal connection area.
For further description of functions and features, the correct preparation and tooling off an receiver-module and installation into the
case is expected.
4 Descr pt on of Operat on
Prior to powering on the receiver, configure first the function that the receiver should execute based on the sender commands.
Delayt me for Key-funct on (Jumper 1)
If jumper 1 is set, the corresponding relay will stay closed with a delay time of 100ms as long as the transmitter key remains active.
Installing the receiver in an RF-disturbed area could result in a chattering (relay contact bounce) during operation if the operating button
is pressed for a longer period. To minimize this effect, all instructions received from a transmitter could be extended to 500ms by
removing jumper 1. The receiver then will operate with delayed-action correctly under RF disturbance.
Key- or Toggle-funct on (Jumper 2)
If jumper 2 is inserted, the relays will stay closed as long as the transmitter key remains active (Key-function). Delay-time set by
jumper 1.
If jumper 2 is removed, it is possible to switch on/off the relays. Each signal command puts the relay into the opposite state. The delay-
time set with jumper 1 is considered to be a „dead time“ between the switching processes. While the timer is running, no new command
is executed.
5 Connect on
All connections must comply with local regulations and standards, including VDE0100, VDE0700, VDE0550/0551, VDE0711
and VDE0860. Only solid core cable is to be used for connection, since stress relief is not provided on the product terminal
connection block. As per DIN 0700 / IEC 335 / EN 60335, no protective earth cable terminal is provided.
According to regulations, this product must only be installed by a qualified electrician. If in doubt seek professional help before
attempting to install. Incorrect Installation can damage the product and connected devices and increase the risk of electric shock,
damaged contacts or fire hazard.
Attention. Extreme danger !
When open ng the product, l ve components may be touched. Isolate SHR-X L3 from the ma ns power supply before
open ng. Ensure that all connected dev ces and components are also d sconnected from the ma ns-power supply.
6 Installat on
Mount the product in a case adequate for 230V~/50Hz mains-voltage.
To avoid damage to electronics, insert cables only via entries on the screw-terminal side.
Connect the power cables for 230V~/50Hz into the correct screw-terminals.
Max. 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 changeover contacts NO/CC/NC 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.
7 Cod ng
After the first connection to the mains each receiver SHR-X L3 could be programmed (taught) with 2 individual address codes with
transmission-key for each relay-output. For programming the code and transmitter-keys, perform exactly as follows:
Set the transmitter (SHT-7/433MHz) to be used to your individual radio-code.
Briefly press one of 3 “learn” buttons (e.g. S1 for Relais K1) .
Flashing LED indicates active in learning mode.
On the transmitter press the button selected for your application (e.g. Key 1 or Key 2+3 together) until the LED flash rate
increases.
The button and radio-code is stored in the receiver. LED continues flashing until the storing procedure is complete.
Check for error free operation of the receiver by pressing the transmitter button(s) again when LED is extinguished. If the
address is learned correctly, the clicking operation of the relay will be audible.
Repeat the procedure for the next relays.
