5-13. Various Display Modes
In this system, various LED display patterns are provided
in relation to the display modes shown in Table 5-8-1.
Operation processes from the status of AC cord plugged
to that of power on and power off will be given below.
(1) Data of the non-volatile memory are checked when
the AC cord is plugged, and all the LED are turned
on in red in the initial use. In second or later use, all
the LEDs are turned on in green and the unit enters
the standby status.
(2) In the standby status, only the ON/STANDBY LED
is turned on in orange, and the main power is off
and the lamp power is also off.
(3) When the power is on by pressing the ON/
STANDBY key, the unit enters a normal status in
passing through following processes.
1) The main power is on, and ON/STANDBY LED
turns on in green.
2) The fan power is on, and the fan starts to rotate.
3) The lamp power is on, and LAMP LED blinks
in green for about 3s.
4) With the lamp turned on, LAMP LED turns on
in green and the unit enters the normal status.
(4) If the lamp does not turn on, ON/STANDBY LED
turns on in orange, and the LAMP LED blinks in
green for about 1 min. and then the unit returns to
the standby status.
(5) In the normal status, ON/STANDBY LED and the
LAMP LED are turned on in green, and the main
power and the lamp power are turned on.
(6) When the power is turned off by pressing the ON/
STANDBY key, the unit enters the standby status in
passing through following processes.
1) When the lamp power is turned off, ON/
STANDBY LED turns on in orange.
2) The LAMP LED blinks in green for about 1
min. For this period the lamp can not be turned
on again by the ON/STANDBY key.
3) When blinking of the LAMP LED stops, only
the ON/STANDBY LED turns on in orange.
After this, the lamp can be turned on again by
the ON/STANDBY key.
(7) Moreover, the fan works for about 2 min. to lower
temperature of the unit. When the main power turns
off, the fan also stops and returns to the standby
status.
(8) If an error occurs due to some causes, the ON/
STANDBY LED turns on in red, and the error
information is kept in the display status of the
LAMP and TEMP LEDs. When the error is
detected, the unit enters the standby status after
cooling down process for about 2 min. In this case,
if the error status continues, the error display is also
kept and any key entry is not accepted.
Table 5-12-1 shows each kind of the drive system IC
control.
