Problem
Description
Motor shuts off.
Motor has been in
use for more than
2 minutes.
When down
button is pressed,
screen stops
halfway
AC Screen won't
run
DC Screen won't
run
Probably Cause
Motor is designed for short
operations (lowering and
retracting), not continuous
duty. Longer operation,
causes the motor to overheat
and shutoff. This typically
happens during installation
when testing the screen.
An intermediate stop was set
for the motor.
SIFI is not powered.
SIFI is not on the local
network.
No AC power available.
No power to 24v DC supply
Action to Take
Allow the motor to cool down.
Complete cooling can take an hour or more. Heat
gain is cumulative and takes time to dissipate.
If motor use is initiated before it has cooled
completely, the motor will shut down again when
it reaches maximum temperature.

Opt. 1
Check the wire pinouts and termination. Look for
broken, loose, or damaged wires. Determinate if
necessary.
Check that the green LED on SIFI is flashing. If not,
make sure power is available via the bus power
supply or PoE (with expansion card only).
Use the service keypad (if available) to validate the
RS485 network and motors are operating properly
before troubleshooting SIFI network problems.
Check that the SIFI is communicating on the local
network. Ping the device via the windows
command prompt, or make sure the device shows
up in the network tab of the Windows File Explorer.
Check to see if the circuit breaker has switched
off. Reset if needed. Check outboard switching
apparatus. Check voltage availability. Contact an
electrician.
Check for power at your plug and/ check for
breaker box.
