3 System operating range
The system is designed for a large operating range. 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 (eg
PC’s) that can produce electromagnetic distortion, may severely reduce the
range of operation and could result in intermittent operation.
Caution
: To avoid influence of “electrical noise” from the load connected to the
receiver (e.g. DC-Motor) install the receiver within a distance of 1 m.
4 Description of Operation
Prior to powering on the receiver, configure first the function that the receiver should
execute based on the sender commands.
Delaytime for Key-function (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-function (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 Connection
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 opening the product, live components may be touched.
Isolate SHR-7 L3
from the mains power supply before opening.
Ensure that all connected devices and components are also
disconnected from the mains-power supply.
6 Installation
•
Using the external fixing lugs, the case of SHR-7 L3 can be wall mounted. Do
not remove the electronic board.
•
Open the cable entries using a suitable piercing tool. To avoid damage to
electronics, only entries on the screw-terminal side should be used.
•
To open the enclosure cover, carefully insert a screwdriver into the slot on side
frames.
•
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.
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.
7 Coding
After the first connection to the mains each receiver SHR-7 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 (Series SH-7 C) 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.
Up to 6 codes could be learned by this way (3x2 per relay). Therefore an older code
could be deleted by learning the new one twice.
The learn mode is completed automatically within approx. 60 sec. In case of error
the teach mode may be interrupted by pressing 2 of the buttons simultaneously.
Pressing learn mode buttons 1 and 3 for a minimum of 3 sec. will delete all stored
data.
In normal operation the LED illuminates if an understandable radio signal is received
by the SHR-7 L3, even if it is not a previously learned signal (HF-Busy).
In case the programmed transmitter-code or transmitter itself should be
changed, it is a requirement that the receiver also be programmed with the
new code.
Operation of the receiver with an unlimited no. off transmitters is possible by coding
the internal tri-dip-switches off all transmitters to the same code.
