Troubleshooting
problem
Lack of transmission. Green LED light (LED1) is working. When button is pressed on
transmitter, the red LED (LED 2) does not function.
Check
Are receiver and transmitter properly encoded?
Solution
Input code for receiver and transmitter (see coding switch)
problem
Wireless control reeacts to proper transmitter. Red LED (LED 2) lights up after button is
pressend on the transmitter but the solenoid does not switch
Check
Is the green LED (LED 3) on? If not, system is in „Standby“
Solution
Set the transmitter in „Active modus“ Press the buttons winch in/winch out
simultaneously for three seconds (see also Stop function)
problem
Wireless control reacts to proper transmitter. RED LED (LED 2) lights up after botton on
transmitter is pressed, green LED (LED 3) lights up, solenoids switching can be heard
but no voltage is measured at output.
Check
Is connector 6 attached to load voltage ?
Solution
Attach connector 6 to load voltage.
Problem
System works for a short period, then stops
Check
Is the system near a source of similiar frequency?
Solution
Turn off source of similiar transmission.
Problem
Effective area of transmission is too small.
Check
Is the second LED on the transmitter on?
Solution
Install a new batterie.
Check
Is the receiver installed close to an electric motor?
Solution
Move to a location away from electric motor. Add an external antenna.
Coding switches
Sender and receiver are assigned via the coding switches. (receiver: coding switch 1)
The coding of the sender and receiver must correspond. An asymmetric coding must be
selected in order to protect against unauthorized switching of the channels. The coding switch
1 in the receiver must be coded before connecting the supply voltage , i.e. first set the same
code for sender and receiver before connecting the
receiver.
function
The radio receiver operates with 6 switching channels and an emergency stop- class 0- which
resides above the other channels. After connection of the power supply the system starts in
the “Standby mode”. A green LED (LED1) flashes. When in this position, no transmission is
possible. After “ON” butten has been activated for around 3 seconds, the system is active.
This position is signaled by a green LED light (LED3) on the main circuit board. The
integrated stop relay is initiated and only after this activation can the winch in and winch out
function be used. If the receiver recognizes a valid signal, a red LED light (LED2) will light up
on the receiver. For each channel there is a relay switch, which switches the connected
power and is turned on when the button belonging to this channel is activated on the
transmitter. Note: It is very important to keep the maximum electrical current in mind. The
system will shut itself down if there has been a five minute time period with no transmission.
Afterwards the system reverts to standby mode.
Emergency stop automatic stop of the category 0 type.
When the red button on the transmitter is depressed, the emergency stop of the category 0
type takes effect. When this happens, immediately the connection is cut to the relay “Stop”
The green LED light (LED 3) goes out. At this point the system is returned to the Standby
position. At the point the transmitter can be brought back online by the steps shown above.
Emergency Stop: Automatically activated emergency stop category 0
The system continually tests if there is a similar transmission on the same frequency within
the utilization field. If there is interference, the system automatically initiates an emergency
stop – category 0. Turning on the unit is, then, only possible when the interference has
stopped. The system is also continually checking the strength of its own signal. When the
maximum range has been reached, the automatic stop is also initiated. Turning on the unit is,
then, only possible when the transmitter is within range.
Multiple scanning
In this operating mode the sent key codes and the set address are scanned and stored twice
in the processor. The transferred values are continuously compared with the stored code. If
the code does not match with the values for a certain time, the stored information is deleted.
Proceed as follows to set this operating mode:
The scanning time can be installed with coding switch B Attention: In this operating mode a
short delay of the switching relays must be taken into account.
Connection of the antenna
An internal antenna is integrated in the housing as standard. The range of the system
depends on local conditions and can be very different . Athmospheric interferences may
influence the frequency. Interferences occur due to the operation and switching on/off of
electronic devices. High degrees of interference mainly occur due to transmission lines,
transformer stations, industrial and electronic data-processing stations. Interference fields of
electromotors must also be taken into account. Keep a large distance to the devices
mentioned above when installing the receiver. The largest range can be obtained if you keep a
long distance to metal items.
(
Observe the distance to live parts !! Interferences !! ) For a
better reception we recommend an external antenna which can be ordered by ELJO. This
antenna must then be connected on the terminals (see connection diagram) and must be laid
out of the housing via an IP 65 screw connection.
