Warning! Problems with the connections and wiring may only be repaired
by a qualified electrician.
Solution
• Check for main voltage.
• Check to make sure if the plug is plugged into the socket.
• Check to see if the batteries are installed properly in the remote control. See
also section 7.3 'Replacing the batteries in the remote control'.
• The thermal overload cut-out of the motor has been activated and has turned
off the motor. Wait 15 to 30 minutes and then try to unroll or retract the
projection screen again.
• Make sure the projection screen is voltage-free and check the connections as
described in section 4.3 'Connecting electrical projection screens'. Check to see if
any wires are loose.
• It is possible that an object (for example, part of the packaging) fell into the case
prior to mounting. Check to see if this is the case and whether this object is what
is causing the noise.
• If the motor has been damaged during transport, please contact the supplier.
• Adjust the projection screen according to the instructions 'Adjusting limit
switches', available on request.
• If the factory settings are no longer present, this may be due to damage during
transport. If this is the case, contact the supplier.
• Consult the connection diagrams in 4.3 'Connecting electrical projection screen'
and switch the brown and black motor wires.
