Q.
Q.
A.
A.
I was setting the limits and it
was all ok but it just stopped
and will not move up or
down electrically but I can
still wind the door by hand.
I have pressed the button
on my handset and
nothing is happening.
The motor provided is a friction drive and as such will generate heat.
If the curtain is open and closed a lot in succession (as it is on initial
installation) the thermal cut out can kick in, if this happens turn the
power off and wind the curtain down by hand so as to allow air to pass
over the barrel and cool down, this can take in excess of 45 minutes.
1
Does the red light come on when you press the button on the handset?
If not then change the battery on the handset.
2
Is the light on the receiver box on? If not then check the power supply
to the control panel.
3
Is a noise coming from the motor when you activate it? If so then check
the security straps, if these are disconnected or broken you will need to
contact the office to purchase some more.
4
Can it be opened by using the manual winding handle? If so then can
it be operated after winding? If this still doesn’t work please contact
your installer, as the safety brake may have engaged and could have
damaged the switch. This will need to be re-engaged or, if broken,
replaced.
Q.
A.
Every time I press to close,
the curtain moves and
then it will reopen.
1
Check to make sure there are no obstructions in the way of the curtain
and that the guide runners are clear of debris and have not been
damaged or dented.
2
The safety edge can sometimes think that strong winds are an
obstruction and as such will re-open. If this is the case, then activate
the hold to run function on your handset or receiver box to close fully
and then return to it another day to make sure it is working OK. If
this keeps happening contact your installer as the sensitivity on your
safety edge may need adjusting.
