Assembly instructions Veranda sunblind VZ520
F. Fault-finding:
F1. Blind will not unroll or roll up:
- The internal final switch points at zero in both directions. Push both adjusting buttons of the motor
and continue adjusting the final switch.
- Wire making poor contact after extending motor cable. Check connections.
- Motor has run hot. Leave ½ hour to cool.
- Faulty adjustment of the limit switches.
- No current supplied to switch. Check using voltmeter.
- Motor wrongly connected. Check using connection chart.
F2. Motor hums:
- Check whether everything can freely turn in both directions. Is anything catching ? (Cable ?)
- Capacitor in motor has blown (as a result of faulty connection of the motor).
- Motor is wrongly connected : check correct connection of motor cables to the switch using the chart
on p.12. A phase wire (brown or black) has been transposed with neutral (blue). The motor will turn
in one direction, but it will hum in the other.
F3. Motor does not switch off in time:
- Faulty adjustment of limit switches.
F4. Internal flap not straight:
- The guide rails are parallel, but not square to the casing. Check by measuring diagonals.
F5. Internal flap slips out of the guides:
- The guide rails are a little too far apart. Adjust them slightly further together.
F6. Internal flap is not straight against the box when rolled up:
- See point 4 above.
F7. Fabric sticks during raising and lowering:
- Internal flap not properly fitted in guide rail.
- Steel cable not running properly over all pulleys.
- Spring blocked.
F8. Fabric not taut at bottom:
- The guide rails are not straight with respect to the box.
(Veranda rails not straight with respect to wall or box).
- Cable sticking somewhere.
- Spring not under sufficient tension.
- Faulty adjustment of limit switches.
- Endprofile runs against the pulleys of the guide rails.
F9. Blinds are not even when unrolled:
- Bad fitting of fabric rolls. Turn one of the tubes 1/4 of 1/2 turn.
