WHAT TO DO IF…?

Malfunction
Possible cause / solution
… the eWickler does not show any sign of
function?
Check your power supply including the connection cable and plug; if necessary, carry out a hardware reset and
adjust the time anew (see p. 26)
… the eWickler does not react in the morning at
the adjusted opening time?
The electronics of the device have switched off the swivel belt winder because the return pulley did not move
anymore.
This is the case if:
1. the lower end position has been set at a spot which is too low. Then, the roller shutter is closed, but the
belt has continued to unwind so that it does not lie tautly on the return pulley anymore.
2. The belt has stretched and the lower end position has changed accordingly.
The belt should not be slack at any time.
Set the lower end position anew (see p. 18) and take care that the belt permanently lies taut on the return
pulley. The return pulley must constantly turn in an even way.
… the roller shutter does not approach the adjus-
ted end positions properly?
It is possible that the end positions have altered because the belt has stretched.
Please adjust the end positions anew (see p. 18).
… the roller shutter stops as soon as you release
the function button?
There are not set any end positions. Please programme the end positions anew (see p. 18).
… the eWickler runs the wrong way round?
The belt has been introduced and mounted on the winding wheel the wrong way round (see p. 12).
Malfunction
Possible cause / solution
… the roller shutter comes to a halt while moving
downwards?
1. Has the roller shutter perhaps come up against an obstacle?
Raise the shutter again and remove the obstruction.
2. Have the roller shutter slats slipped/ shifted their position?
If possible, raise the shutter again and adjust the slats.
3. In the roller shutter box, the shutter rubs against the window frame due to missing pressure rollers, or
insulation material has come loose and is obstructing the shutter.
Open the roller shutter box and remedy the fault. If necessary, lubricate any stiff points or spots at which the
shutters have trouble moving with greasing wax.
4. The roller shutter might be too light.
Weigh the shutter down, e.g. by sliding a suitable flat iron bar into its bottom slat.
… the roller shutter suddenly stops while moving
upwards?
1. The device’s obstacle recognition control has reacted and intervened, e.g. because the roller shutter froze
solid or it encountered other obstacles.
Remedy the cause (e.g. by slightly/ gradually defrosting the frozen shutter).
2. The roller shutter might not be operating sufficiently smooth.
Examine the roller shutter and its rails.
3. The roller shutter might be too heavy.
The eWickler’s maximum traction power has been exceeded (see p. 7).
