Motor does not run
•
Check to make sure power is on
•
Check to make sure the screen interlock is installed and connected
properly (See page 11.) or, check to make sure the jumper is installed
across the two gray terminals on block 10. (See main wiring diagram on
page 7.)
Skylight closes for unknown reason
•
Check to make sure the rain sensor is clean – debris or bird droppings can
activate the rain sensor. Clean with a mild soap.
•
The motor system may have closed the skylights due to a power outage.
Normal operation is to close the skylights when the power comes back on.
The motor will not respond from the wall switch
•
Verify the connector on the back of the switch is connected properly to the
control unit. See installation instructions supplied with the wall switch unit.
Skylight does not open fully
•
The motor system is programmed to only open a skylight to 90% of full
opening. This is done to protect the hardware from repeated high
stresses. Full opening can be achieved by pressing the open button
repeatedly once the skylight has stopped.
The skylight will not open more than a couple of inches
•
The control system needs to be re-initialized. Follow “System Reset”
procedure below.
•
If the problem reoccurs, the lifting chain my need to be lubricated. Use a
dry lubricant only.
When bench testing the motor system, the motor will not stop
•
This is normal operation. The control unit is looking for a current rise
caused by a motor stall to turn the motor off.
Skylight does not fully close
•
The control system needs to be re-initialized. Follow “System Reset”
procedure below.
Motor system is not functioning as expected
•
Interrupting the power to the control unit for a short period of time
(approximately 30 seconds) will clear some operating errors. When power
is re-applied the unit should close automatically. Normal function should
be restored.
•
If normal function does not return, a partial or full system reset my be
needed. See System Reset on page 22.
