SmartPanel Projector Driver Application Note
III. TROUBLESHOOTING
Additional tips can be found in the SmartPanel Configuration and Installation Guide.
The Projector keeps turning itself off!
Verify that the C45XU's Economy Mode is set to OFF as explained in the Special Note in the Control
Wiring section of this document. If the Economy Mode is on, the projector will shut itself off after
fifteen minutes. If power polling or a third party power current sensor is being used (e.g., AMX-PCS),
the Panel will automatically shut itself off also. If not, the Panel will remain on and you will have to
power the Panel off with the Off button and wait until the lockout timer expires before you can re-
power the projector.
The Panel does not do anything at all.
When power is applied to the Panel it should run through a brief power on self-test, during which all of
the Panel lights will turn on and off in sequence. If you do not see this self test, make sure power is
connected correctly and that polarity is correct.
The Panel keeps turning itself off even though the projector is on.
The Panel turns itself off when power status feedback indicates that the projector is off. If a third
party power current sensor is being used, check to make sure that it is correctly wired, and that it is
correctly calibrated according to the manufacturer's instructions. If not, make sure that the Panel is
configured with None or Power Polling under power status feedback in the Configuration Utility's
Wiring Options tab.
IV. TECHNICAL NOTES
1.
By default, projector power is verified by polling every few seconds via the RS-232 port. Power
polling can be suspended by depressing and holding the On key; polling will be restored when the
key is released. Should the Sharp power off, the Panel will usually detect this condition and power
off within twenty seconds. Should the Sharp power on, the Panel will usually detecting this condition
and power on within ten seconds.
2.
The Sharp is controlled via RS-232 and Infrared with this Driver. Wired remote can not be wired as
the Sharp does not have a wired remote port. A discussion of the advantages of Wired Remote
versus IR can be found in the SmartPanel Configuration and Installation Guide.
3.
The lockout timer specifies the amount of time allowed between sending POWER OFF and POWER
ON to the projector (the delay allows the projector bulb to cool before re-powering). This delay can
be configured using the Configuration Utility; however, adjusting the lockout timer delay is
strongly discouraged as rapid re-powering causes undue wear on the projector's bulb. Also, the
Sharp will not allow power to be restored before a minimum delay has expired. Therefore, disabling
the lockout delay will cause potentially confusing Panel behavior.
