will not run.
- The Fire LED is OFF. If the Fire LED is Solid Blue, this
indicates that the unit is receiving a disabling signal from
the existing re system. If the jumper is being utilized, then
please verify that the jumper is properly installed.
- The Power LED is Solid Blue. If the Power LED is
Blinking Blue, then the supply power has been detected
as out of range. In this case, the Error LED will also blink.
Please verify the power source.
- The Error LED is OFF. The Error LED will be Blinking Red
when the module has detected a recoverable motor fault
condition. This will often resolve if the module is power
cycled and re-calibrated. If that does not resolve the issue,
or if the Error LED is Solid Red, please contact customer
service.
- Verify that the door isn’t being prevented from movement
by some sort of physical obstruction or mechanical binding.
This could include a previously existing latching mechanism
that is not supported by the 6440 product.
19b ISSUE: The door opens too slowly or does not open
fully.
• The 6440 will attempt a learning cycle if it has recently
experienced a power loss. During this cycle, the L speed LED
will be Blinking Blue, and the door will open slowly to check
for obstructions. After successful completion, the door will
return to the previously calibrated speed setting. If the module
appears to be unable to complete this learning cycle, a re-
calibration will resolve the issue.
• The door speed may need to be increased. If the low speed
is not due to a learning cycle, there are several methods for
increasing door speed. Please check the following:
- The user selected speed can be increased all the way to
the H setting.
- The closer’s spring setting can be decreased using the
closer’s adjustment tool.
- The closer’s hydraulic backcheck can be adjusted using the
closer’s adjustment tool.
• Verify that there are no hidden obstructions preventing the door
from mechanically operating.
• If there are no obstructions and increasing the door speed
does not resolve the issue, please attempt a re-calibration.
19c ISSUE: The door closes too slowly or does not close
all the way.
• Verify that the closer is adjusted properly. The spring settings
or hydraulic settings may need to be adjusted using the
closer’s adjustment tool in order to ensure a full closure.
• Verify that there are no hidden obstructions preventing the door
from mechanically operating.
• Consider enabling power boost if it is not already. Power boost
helps overcome natural resistance close to the latch and may
be utilized to ensure a full closure.
LFor any other operational issues, please call customer
support.
