III. TROUBLESHOOTING
Additional tips can be found in the
Smart Panel Configuration and Installation Guide.
The Projector keeps turning itself off!
Verify that the NV6XU’s
Economy Mode
is set to
4
as explained in the Special Note in the
Control
Wiring
section of this document. If the
Economy Mode
is set to Mode 1 or Mode 2, the projector will
shut itself off after fifteen minutes.
If a third party power current sensor is being used (e.g., AMX-PCS), the Panel will shut itself off also. If
not, the Panel will remain on and you will have to power the Panel off with the
Off
button; wait until the
lockout timer expires; and then re-power the projector on, before changing this setting as described in
the Special Note.
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
under power status feedback in the
Configuration Utility’s
Wiring Options
tab.
IV. TECHNICAL NOTES
1. By default, projector power status is not verified using this Driver, because we cannot use RS-232 for
polling.
We strongly recommend using a third party power current sensor
(e.g. AMX-PCS) to
enable the power to determine whether the projector is on or off, and remain in sync with it.
2. The Sharp is controlled via Wired Remote/IR only with this Driver. Either infrared or wired remote
may be wired. A discussion of the advantages of Wired Remote versus IR can be found in the
Smart
Panel 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.
